A TREATISE (continued 6)

Case I. Francis Leclert, of a sanguine temperament, fell on the 7th of October, 1790, on his right knee, and produced a transverse fracture of the rotula. He was not able to rise; he was carried home, where a surgeon, on discovering the nature of his disease, advised him to be taken to the Hotel-Dieu.

He was conveyed thither on the day following, and, in the interval, a considerable swelling had occurred around the joint. The usual bandage was employed; the pains ceased immediately after its application; a copious blood-letting was directed, and a low diet was prescribed.

The whole apparatus was wet with vegeto-mineral water, two or three times a day. On the next day some light food was allowed, and the quantity increased by degrees, till in a short time the patient returned to his usual regimen. Eighth day, the swelling being almost gone, the bandage had become relaxed it was therefore reapplied. Every day the inclined plain formed by the bolsters was carefully examined, and put in order again as often as it became deranged.

Fifteenth day, a new application of the apparatus: twentieth day, an evacuation in consequence of a bilious disposition. Nothing particular occurred from this time till the completion of the cure, which took place on the sixty-seventh day after the accident: no depression existed at the place of the fracture: the motions were perfectly free; these were aided, by daily exercising the knee joint for some time.

Case II. Vincent Grenier, aged thirty-eight, making a false step, fell on the rotula, and fractured it, on the 6th of June, 1791: he was brought to the Hotel-Dieu, where Desault demonstrated to his pupils, by the usual signs the existence of the disease: a considerable swelling had already taken place. The bandage formerly described was applied: the same precaution as in the preceding case; apparatus examined every day; renewed as often as relaxed; extension maintained with great exactness. On the forty-fifth day, the consolidation was nearly effected; on the fifty-second it was complete, the joint was exercised for some time, and on the seventy-seventh day the cure being in all respects complete, the patient was discharged.

MEMOIR XIV.

ON THE FORMATION OF FOREIGN BODIES IN THE JOINT OF THE KNEE.

1. The history of foreign bodies divides itself naturally into two great sections; the one includes those that are introduced from without; the other such as are formed within our own systems. This latter section may be again divided into two classes; to the first class belong bodies altogether inorganic, such as the different kinds of stones; to the second, those which are truly organic, and become foreign only by being situated in places where they impede the functions, such as cartilaginous or bony productions, existing accidentally within the joints.

On the subject of the latter class, art is much more deficient than she is with regard to the former. Let us endeavour to assist her a little, by giving a sketch of the opinions and practice of Desault with respect to these productions.

2. Before his time, the surgery of France appears to have contained scarcely a record of this affection. Described only in some ancient works, such as the writings of Pare, it had been forgotten by the moderns, when numerous instances of it were suddenly met with by English and German surgeons, and soon afterwards by Desault, who illustrated and confirmed the practice of his predecessors in it, and even added something of his own.

3. All the joints may become the seat of these concretions; Haller found many of them in that of the lower jaw; Bell mentions, as a very rare occurrence, their existence at the junction of the foot with the leg. Some authors have met with them in the wrist; but none are more common, or merit more particular attention, than those that exist in the joint of the knee. To these alone shall the following observations be confined, because these alone have fallen under the notice of Desault.

§ II.

OF THE VARIETIES.

4. Concretions of the joints do not always assume the same aspect. They vary greatly as to number, size, figure, structure, &c. In general, these bodies exist singly; sometimes, however, two of them are found in the same joint, and then they may be extracted either at the same time, or in succession, as was once done by Desault. Some English surgeons have also met with two concretions, and Morgagni has found even twenty-five, in the same joint.

5. They vary also in size. The largest ever met with by Desault, was fourteen lines in its longest, and ten in its shortest diameter. Six lines diameter in every direction, was the measure of the smallest one that occurred in his practice.

6. Their figure is sometimes lenticular and smooth on both sides, sometimes unequal, rough in one part, even in another, concave on one side, convex on the opposite, sometimes marked around the circumference and sometimes not with reddish points, and having occasionally a stem of a cellular texture and of some length, as may be seen in a paper by Theden. They usually consist of a single mass, but are in some cases divided into several lobules united by a kind of ligaments, as in the fourth case related in the Journal of Surgery. Though most frequently detached and floating in the interior of the joint, they have yet been found adhering by means of small portions of cellular substance, loose and capable of being stretched, or tight, hard, and even of a ligamentous nature.

7. If, from the external figure, we pass to the structure of these bodies, we will find them existing in three different states. Sometimes purely cartilaginous, sometimes completely bony, they at other times partake of both these states, in which case a bony nucleus is covered with a cartilaginous crust. Out of five cases, recorded by Desault, three are of the first, and two of the third kind. Many authors have met with the second kind, particularly Morgagni, who has even found in the same joint, some bodies of a bony and others of a cartilaginous nature. Hence it appears, that this variety of structure is to be attributed to the longer or shorter standing of the disease, that every concretion must pass successively through these three states, and that there is a great analogy between the formation of such bodies and natural ossification.

8. If we examine a body of the third kind cut in two through the middle, we will find it red and vascular in the centre, like an epiphysis, even when it is floating in the joint perfectly loose and free from adhesion.

9. Bell, in his treatise on surgery, speaks of a kind of tumour, at first soft, membranous, and adhering to the internal surface of the capsule, but which, according to him, may become afterwards hard and solid, and be detached so as to float loose in the joint. But are not these tumours different in their nature from those destined to be converted into bone? Do they, in fact, ever undergo the changes mentioned by Bell? Desault having never met with any of them, was unable to offer an opinion on the subject. In the mean time, an observation made by Monro, may serve to throw some light on the question: he once saw, in one of these productions, a cellular nucleus surrounded by a covering of bone.

10. Though usually simple and free from complication, this affection may, according to some authors, give rise occasionally to a dropsy in the joint. Pare is the first who has made mention of this: he found one of these bodies in a patient’s knee, into which he had made an incision for the purpose of drawing off a collection of water. Simson, on extracting a similar body, gave vent to four ounces of water. But, as on the one hand, a dropsy of a joint oftentimes exists without these foreign bodies; so, on the other, these bodies are almost always found disconnected from dropsy. Nor is there any affinity between the acknowledged causes of an accumulation of synovia, and the presence of these bodies; so that when the two diseases do exist together, it is altogether probable, that they are independent of each other.

§ III.

OF THE CAUSES.

11. The formation of articular concretions succeeds frequently to blows or falls received on the joint, in which case, a swelling more or less considerable in the surrounding soft parts, showing itself from the first, and remaining for some time, at length allows the foreign body to be perceived, and does not, in general, disappear during the continuance of the body in the part.

12. Sometimes no external injury contributes to the formation of the body, and then, a spontaneous swelling precedes its detection, as Desault observed in two patients, where nothing was known to have concurred in the production of the disease. Constant rest increases this swelling, while exercise and a temperate mode of life diminish it.

13. But what can be the immediate cause of these tumours? Are they, as some allege, an aggregation or crystallization of particles of matter conveyed into the interior of the joint by the synovia, in the same manner as the rudiments of a stone are conveyed into the bladder by the urine? Their organic appearance and the vessels that pervade them, are unfavourable to such an opinion. Can they be, agreeably to the conjecture of Theden, articular glands bruised by means of strokes or falls? Or are they, as some authors will have it, portions of the cartilage of the joint, detached by the same causes? How then will their spontaneous formation be explained?

But why trouble ourselves about the cause, provided we can remedy the effects? Nature conceals from us the means, and discloses to us nothing but the results. Theories are fluctuating; but experience is still the same: let us search, then, by an attention to facts, for that which we cannot learn from first principles.

§ IV.

OF THE SIGNS.

14. The phenomena which announce the presence of foreign bodies in the joint of the knee, are sometimes clothed in a character of such evidence, that they cannot be mistaken; at other times, the nature of the disease eludes the most accurate researches: the cause of this variety may be easily perceived.

As the joint presents different depressions and eminences, and as the bodies, being usually loose and detached, may travel through its whole extent, they produce different effects, according to the particular situations which they occupy. If lodged in a depression, they are not compressed, and cannot, of course, give rise to any troublesome affection. If they bear on an eminence, such as the condyls, or the posterior part of the rotula, they are forcibly compressed, and must derange, in some measure, the functions of the joint. Hence the precise nature of the affection cannot be at all times derived from the state of the symptoms.

15. Sometimes the patient can stand and walk with perfect freedom and ease, while, at other times, a sudden pain seizing him, obliges him to sit down, or even causes him to fall, if there be nothing at hand to support him. This pain subsists for a longer or shorter time. One motion produces it, and sometimes another, made in an opposite direction, removes it. But in common it is of some continuance, and then the patient is obliged to keep his bed.

16. If the state of the joint be examined, it will be found more or less swollen, when the pain is very acute. When the pain ceases, the swelling in part disappears. It is never sufficient to prevent the fingers, when drawn along the external surface of the joint, from discovering the presence of the foreign body, when it forms a protuberance under the integuments. It is then found sometimes above the rotula, by the side of the tendon of the extensor muscles, and that is the place where it usually produces least pain; at other times, it is lower down, in front of the condyls, and by the side of the rotula. It is occasionally found immediately behind the tendon of the extensor muscles; in this case so acute is the pain, that the patient is generally unable to stand. But it is when it is situated behind the rotula, near to the projecting ridge which runs across its posterior surface, that it gives rise to the most serious affections.

17. The body passes from one place to another, on the least motion, and sometimes, as Bell observes, the patient, on changing his position during sleep, is awakened by severe pain, in consequence of the foreign body being moved by this change. It happens, in certain cases, that it disappears, and lies concealed for some time, in the back part of the joint. During this period the joint performs all its functions with freedom and ease. Desault made this remark, in the case of a captain of dragoons, from whom, for the first time in his practice, he extracted one of these bodies, and who, for six months previously, had been able to perform all the motions of the joint freely, without pain. This person, experiencing no uneasiness, considered himself perfectly cured, when the body suddenly reappeared, in consequence of a hasty extension of the leg.

18. If the body, when projecting under the integuments, be gently compressed, it yields to the pressure, changes its situation, and, according to the impression it has received, moves either to the internal or the external side of the joint, or reciprocally from one side to the other, passing also behind the rotula, behind the inferior ligament, or sometimes behind the tendon of the extensor muscles. In these alternate displacements, it may in some cases be turned round, in such a manner that its anterior surface will take the place of its posterior one, and then resume its primitive situation. Desault met with an instance, in which the patient himself was in the habit of turning the body round in this manner.

19. Bell, in conformity to the distinction of articular concretions into cellular and solid, attributes to each division its peculiar signs. In the first case, the pains, being rather obtuse than sharp, are constant; in the second, they are extremely acute, but disappear and return at intervals. Supposing the division to be a real one, cases of the last description certainly occur much more frequently than those of the first.

§ V.

OF THE TREATMENT.

20. From what has been said it follows, 1st, that these cartilages floating through the joints, do mischief mechanically (14), by coming into contact with the articular surfaces: 2dly, that to obviate this mischief, it is necessary either to prevent their contact, by fixing the bodies in a spacious part of the joint, and thus doing constantly what nature does on certain occasions, or to extract them through an opening made into the articular cavity.

21. Hence, art can have recourse to but two methods of cure, all hope of discussing these tumours by external applications being, as Bell observes, entirely extinguished.

22. The first method was proposed by Middleton and Gooch, who having brought the foreign body into a situation where it produced no pain, endeavoured to confine it there a length of time sufficient to make it form adhesions with the corresponding part of the capsule. As we are not informed of the result of the experiments of these two physicians, we are left to our own conjectures on the subject.

23. Are these foreign bodies capable of forming adhesions? Supposing they are, will the internal surface of the capsule attach itself to them at the pleasure of the surgeon? Even admitting the existence of both these conditions, by what means can the bodies be kept stationary for a length of time sufficient for the formation of these adhesions? Will they not be displaced by the slightest motion? Besides, experience seems to be unfavourable to the expedient. I have already said (17) that, in a certain case, the foreign body disappeared for six months, remaining, no doubt, during that whole time, in the same place: but, if it could not, on that occasion, form adhesions, if a motion was sufficient to produce its reappearance, can we expect that art will be more fortunate in her attempts?

24. But, even admitting that the foreign body does form these adhesions with the capsule, if it should increase in size in the part of the joint which it occupies, becoming in a short time disproportioned to its extent, it will impede motion as before, and produce, by degrees, nearly the same affections.

25. From these considerations it follows, that the only expedient which can promise a radical cure is, the extraction of the foreign body. In the performance of this extraction, an incision must first be made through the integuments and the capsule.

26. This operation, simple and easy in itself, has given rise to apprehensions as to its consequences, which have long prevented practitioners from undertaking it.

It was in former times a maxim in surgery, that wounds of the joints are, if not mortal, at least extremely dangerous, in consequence of their admitting air into contact with the articulating surfaces. But observation has demonstrated the fallacy of this doctrine, and Desault in particular, has thrown great light on the subject, as I have frequently had occasion to mention in the course of this work: so that, at the present day, it is clearly ascertained, that, if judiciously treated, these wounds are seldom productive of serious consequences.

27. Hence it follows, that the operation we are considering, when skilfully performed, never gives rise to any dangerous or disagreeable affections. Experience has proved the truth of this assertion in the practice of Theden, Simson, Gooch, Broomfield, Bell, and Desault, the latter of whom performed the operation five times with complete success. The only case in which he was less fortunate, was that of a man, in whom the wound of the integuments closed up at first without any accident, but which was succeeded by two abscesses, one in the thigh, and the other in the leg, but without any affection of the interior of the joint. This patient was subject to a wandering rheumatism, which oftentimes attacked the lower extremities, and was perhaps in the present case the chief cause of the unfavourable occurrences.

28. It is to the English that we are indebted for the first operation performed for the extraction of these bodies. An account of this is given in the Transactions of a society in Edinburgh. Since that, the operation has been frequently repeated, and more than ten instances of it were already on record, when Desault first performed it in France. His method, somewhat different from that of others, was as follows.

1st, The patient must be laid on a bed, or seated on a high chair. The first position, however, is to be preferred, because when it is adopted, the patient need not be moved after the operation.

2dly, The leg is extended on the thigh, in order to relax the anterior part of the capsule of the joint.

3dly, The surgeon then searches for the foreign body, moves it to the internal side of the joint, against the attachment of the capsule, and secures it between his thumb and the fore-finger of his left hand, while an assistant draws the skin over the fore part of the rotula.

4thly, Taking then a common bistoury, he makes, on the protuberance formed by the body, a longitudinal incision of an extent proportioned to its size, through both the integuments and the capsule, so as to lay the body bare at the first stroke.

5thly, Sometimes the body escapes immediately of its own accord, in consequence of the compression made on it by the fingers. If its passage out be not spontaneous, a small scoop or a taper-pointed spatula passed under it, answers the purpose of extracting it. But, in the introduction of these instruments, it is necessary to avoid touching the articulating surfaces with their ends, lest, by being irritated, they might swell, and give rise to troublesome accidents.

6. If any resistance be met with, enlarge the opening and the extraction will become easy. Without this precaution, the edges of the wound, being bruised and irritated by the passage of the body, will swell, inflame, and unite again with difficulty.

7. When the extraction is finished, the assistant who draws the skin towards the inside of the joint, suddenly lets it go, when it returns to its natural situation. This causes the two incisions, which corresponded, at the time of the operation, to change their relative situation, the one remaining internal and the other becoming external.

8. Hence arises a twofold advantage; the entrance of air into the interior of the joint is prevented, and the external and loose portion of the capsule, being drawn inwards with the skin, unites with the condyl, if it be not brought into exact apposition with the other portion of the capsule, divided near its attachment.

9. The extraction being finished, it is then necessary to examine carefully, in order to ascertain whether or not the joint contain any more of these foreign bodies. On some occasions, when this is even the case, they cannot at the time be discovered. Desault himself was once deceived on this score, in consequence of which his patient was obliged to submit to a second operation.

10. The incision in the integuments is now united by means of adhesive plaster. Over this are laid compresses and a little lint, and the whole secured by a few turns of a roller drawn moderately tight.

11. The leg being then placed on a pillow, is kept in a state of extension, by means of a splint applied, for a few days, behind the joint.

29. If we examine but for a moment the process in this operation, we must perceive, that an incision made through the skin and capsule at a single stroke, is, in no respect, less advantageous than one made at two strokes, as recommended by all practitioners, and that, it is in the following respects greatly preferable to it: 1st, it shortens the operation very considerably: 2dly, it diminishes the pain: 3dly, it exposes the joint a much shorter time to the contact of the air.

30. The object of the operator is better answered by drawing the skin outward and towards the rotula, than by either depressing it, as Broomfield did, or raising it, as Bell does. Being more loose and more easily stretched in this direction, the opening in it is removed farther from that in the capsule, which prevents more certainly the access of air to the joint, and also favours the examination of the capsule.

31. In the mean time, the operation may succeed, even although the openings in the integuments and the capsule correspond to each other. Many English and German practitioners, without previously stretching and changing the natural situation of the skin, make a common incision, which they dress afterwards like a simple wound, and are yet no less successful than others in the result of their operations. This is a further proof of the fallacy of the ancient surgical doctrine, respecting the admission of air into the cavities of joints. Perhaps Desault might have omitted this precaution, had any operations of the kind occurred in his practice during the last years of his life.

32. The operation is seldom attended with much pain. Only one patient manifested signs of this in the practice of Desault. Nor have those operations of the kind performed in England been more painful, so that it may be laid down as a principle, that in most cases no primitive accident is to be dreaded.

33. With regard to hemorrhagy, as there is no large artery near the place of the incision, there is nothing to be apprehended on that score. Oftentimes there is scarcely any loss of blood at all, as may be seen in the first case published in the Journal of Surgery. But, even admitting that a small articular branch be divided, the reunion of the edges of the wound will be sufficient to check the hemorrhagy, in the same manner as in the operation for the hare-lip, the contact of the divided integuments of the lip, puts an end to the hemorrhagy from the small arteries of the part.

§ XIV.

OF THE SUBSEQUENT TREATMENT.

34. I have already said that but little is to be apprehended on the score of accidents subsequent to the operation (26). Out of the numerous operations of the kind performed lately in Europe, but few cases have proved troublesome in their consequences, and even these were influenced by some foreign circumstances. Thus, for example, one of the patients of Simson rode out on horseback a few hours after the operation, on a cold and stormy day, and thus produced a troublesome affection of the part. A similar remark may be made respecting the case formerly mentioned (27).

35. The apparatus or dressing remains untouched for the two or three first days, during which time it is necessary to wet it frequently with vegeto-mineral water. It is a certain truth, that the use of this liquid retards the suppuration of wounds, and that, when continued a due length of time, it keeps inflammation at that degree most proper for the process of healing.

36. On the removal of the dressing, the wound is sometimes so perfectly healed up, as not to exhibit the least discharge. At other times a slight suppuration takes place; but, at the end of a few days, the cure is complete. Under the care of Desault, it was always effected in eight or ten days.

37. Let us bring the doctrine just laid down to the test of experience. Five cases have been published on this point. I have selected two of them, both which occurred in the same subject, where we find the same operation twice performed with equal success.

Case I. M. Vielle, aged nineteen, was attacked about the beginning of the year 1790, by a spontaneous swelling in the joint of the knee. Inconsiderable at first, but increased afterwards by a laborious journey, it disappeared at the end of two months, discovering to the touch, near the internal edge of the rotula, a foreign body, which was hard and moveable, and which somewhat impeded the motions of the joint.

About a month afterwards, the swelling returned, and, having continued for three months, disappeared again, when the body was found at the external side of the rotula, increased in size. Sundry external applications were tried for six months without success.

Weary of this unavailing practice, the patient came, in March, 1791, to consult Desault, who discovered a cartilaginous substance of a flat and circular figure. Its usual situation was at the external side of the joint, but it could be easily moved to the internal side, and could be turned on its own axis within the joint, nor did it occasion any pain, when suffered to remain at rest by the side of the rotula. But, when it passed behind the tendon of the extensor muscles, the patient was unable to stand, and he experienced severe pains when it made its way under the condyls or behind the rotula.

The indication was evident. Before the operation Desault prepared the patient by a proper regimen, and then, in the method already described (28), extracted a foreign body, whitish, and oval, fourteen lines in length, ten in breadth, and two and a half in thickness at its middle. It consisted of three pieces, united by a ligamentous substance, and was smooth on the side next the joint, but rough with irregular tubercles on the opposite side, and on its circumference. There was no loss of blood during the operation: the usual dressing was applied, after the most attentive examination, as to the existence of a second body.

Neither pain nor swelling supervened, and by the fourth day, the reunion was complete. In a short time motion was performed with as much ease as before the occurrence of the complaint. In the mean while, a degree of uneasiness remained in the joint; but barely perceptible at first, this uneasiness continued to increase; in about four months, symptoms of the existence of another foreign body made their appearance.

M. Vielle being now a distance from Desault, put himself under the care of his brother, who extracted a second body, in the manner already described, except that the incision was made at two strokes.

Dressing the same as in the preceding case, with this additional precaution, that the thigh and leg were covered by a roller, for the purpose of moderating the action of the muscles.

No fever, no pain; the reunion completed on the eighth day, except a small point in the centre of the wound, which suppurated slightly till the fourteenth. There was now neither difficulty in walking, nor the least sensation of pain. Since that time, M. Vielle has enjoyed the entire use of his limb.

OBSERVATIONS AND REFLECTIONS ON FORMS OF APPARATUS FOR FRACTURES OF THE LEG.

§ I.

1. Case I. (Reported by Levacher). Catharine Belet, aged fifty-five, of a strong and vigorous constitution, fractured her leg in the middle, by a false step in alighting from a carriage. Being carried home, in a careless manner, she was visited by a surgeon, who merely reducing the fracture, but applying nothing to retain the reduction, sent the patient to the Hotel-Dieu. She was conveyed on the same day to the amphitheatre, where Desault discovered the existence of the affection by the following signs.

Pain in the middle of the leg, less severe when the limb was at rest, more so when it was suddenly moved; the patient absolutely unable to support herself on it so as either to stand or walk since the accident; inequalities sensible to the touch on the anterior surface of the tibia; a shortening or contraction of about half an inch; a preternatural mobility at the place of the fracture; evident crepitation, produced by the rubbing of the fragments against each other, when moved in contrary directions: a change in the direction of the lower fragment, which was bent somewhat outwards. These signs, added to the circumstance of the fall, evidently announced a simple fracture of both bones. The reduction was effected in the following manner.

One assistant made counter-extension by grasping the lower part of the thigh with both his hands, the fingers being placed behind it, and his thumbs corresponding to its anterior surface. Another made extension, not as writers recommend, at the lower part of the leg, but on the foot itself, which was taken hold of in such a manner that the fingers met on its upper side, while the thumbs crossed each other on its sole. In this way a lever of the first kind was formed, the resistance to which was the fragment to be replaced, while its centre of motion was in the joint.

Extension being directed at first in the course or line of the displacement, till the limb had attained its usual length, was then directed in such a way as to restore to the leg its natural form. By this, the fragments being brought into apposition, united exactly without the process of coaptation being employed.34 The apparatus, usually employed by Desault in such cases, was applied to maintain the reduction: the different pieces of it had been previously arranged on a pillow in the following order: 1st, four strong pieces of tape placed at equal distances from each other; 2dly, a junk-cloth,35 long enough to reach from the knee beyond the sole of the foot; 3dly, a bandage of strips, similar to that described for the thigh (page 246), arranged in the usual mode; 4thly, two long compresses, the lower one of which being the longest was turned back on the other; three bolsters had also been prepared; these, being formed of several pieces of linen joined together, were about one inch and a half thick: the broadest of these was designed to be placed on the anterior part of the leg; the two other lateral ones, though narrower, were a little longer, in order that, by folding back on themselves, they might be accommodated to the inequalities of the limb; 6thly, lastly, there were also prepared two splints, an inch broad, three lines thick, and of the same length with the junk-cloth.

Every thing being ready, the assistants still keeping up extension raised the leg a little, while a pillow was slipped under it, to support it equally and uniformly throughout its whole length. The leg was placed on this pillow in such a way as to correspond exactly to the middle of the apparatus which was arranged in order on it, and was previously wet with vegeto-mineral water.

On the anterior part of the leg was then applied a long compress, extending from the knee to the upper part of the foot. Over this were lapped the other two compresses, which had been previously placed in order as part of the apparatus. These were then secured by the bandage of strips, the application of which was begun at the lower strip next to the foot, and continued successively upwards with the rest, making them cross each other at the anterior part of the leg.

On the sides were placed the bolsters which were doubled at the ancle to protect that part from the pressure it might otherwise sustain. The splints were then applied along the external surfaces of the bolsters, the edges of the junk-cloth having been previously folded round them, in order to render their pressure the more close and steady. Along the fore part of the leg was laid the largest of the bolsters, and the whole was then secured by the four pieces of tape tied on the external splint, with a degree of tightness sufficient to keep the fragments immoveable.

A compress wet with vegeto-mineral water covered the foot, and was secured by a roller, applied in such a manner, that its two ends, crossing on the back of the foot, were fastened laterally to the two splints.

The leg, being firmly fixed by this apparatus, and gently flexed by means of a pillow placed under it, was protected by hoops from the pressure of the bedcloaths. The fragments being now in complete apposition irritated the parts no longer, in consequence of which the pain ceased.

The patient being properly disposed in bed, remained tranquil and easy throughout the remainder of the day. Diluting drinks and light nourishment were prescribed.

Next day, no pain; patient composed; a slight swelling on the back of the foot; the apparatus wet anew with vegeto-mineral water. Fourth day, the bandages a little relaxed; the point of the foot turned somewhat outwards; a new application of the apparatus. Seventh day, bilious symptoms appear, loathing of food, nausea, and bitterness of the mouth. Eighth day, tongue furred, inclination to vomit; loss of appetite; a grain of tartar emetic given in solution; copious dejections; evidently better: next day, appetite returned, tongue clean. Tenth day, a third application of the apparatus, which had become too loose. Fifteenth day, fresh bilious symptoms; further evacuations; success the same. Twentieth day, consolidation evidently advancing; no deformity of the limb; fourth application of the apparatus. Thirty-second day, consolidation almost complete; the apparatus still kept on till the forty-second day, when the patient was discharged perfectly cured.

2. This case, which is in no respect different from those that most frequently occur in practice, presents us with a view of the mode of reduction, the means of retention, and the subsequent treatment, employed by Desault, in cases of the kind. The advantage of the bandage of strips, which allows the limb to be uncovered without being disturbed, is now generally acknowledged in fractures of the lower extremities. In the treatment of these, practitioners reject entirely, at present, the roller bandage, which was recommended by Petit, Heister, and all the authors who preceded them, and which, by producing a new displacement, at each time of reapplication, may entirely prevent the fragments from uniting. The bandage of Scultet, brought into use again by Desault, the form of which has been just described, is also preferable to the eighteen-tailed bandage, which some practitioners still employ.

3. The strips which compose the former bandage, being narrower than the tails of the latter, can be more neatly applied to the leg, as they more readily mould themselves to its inequalities; the compression made by them is, therefore, more exact, more uniform, and consequently less inconvenient. If one of the strips become soiled, it can be changed without deranging the bandage. (Respecting this point, see what was said on fractures of the thigh.) This bandage being less bulky than the eighteen-tailed one, is therefore less troublesome to the patient.

4. The broad and strong splints which form a part of this apparatus, have the following advantages over those previously used both by the ancients and the moderns; 1st, they come in contact with and bear on a larger extent of the surface of the limb; 2dly, they consequently maintain the fragments in apposition with greater firmness and effect; 3dly, they prevent the rotation of the foot outwards, an accident which very frequently occurs when the fracture is complete, that is, when both bones are broken; 4thly, they remain constantly in their place, without slipping either forward or backward, an inconvenience necessarily attendant on the other splints, which, from their roundish form, touch the limb in only one point or line.

5. To sustain the foot, Petit recommends a piece of a board to be applied immediately to its sole, and supported by two bits of tape fastened to the splints. This practice is adopted to some extent even at present: but a simple roller, applied in the manner already mentioned, is sufficient for the purpose; the tendency of the foot to turn outwards is never so strong as not to be effectually resisted by this expedient: besides, should the piece of board be placed ever so little too vertically, it retains the foot in a state of inconvenient and painful flexion.

6. The situation of the leg, gently flexed by means of a thick cushion or pillow placed between it and the mattress, is, in all respects to be preferred to the method of Pott, which is exclusively adopted by Bell. What, indeed, can be the object of this latter method? To relax, say they, the muscles, that tend to make the lower fragment overlap the upper one. But is it not evident, that most of these muscles, not being attached to the os femoris at all, cannot be influenced by this position? To obtain the relaxation of the posterior muscles, it is necessary to flex the foot; but, in such a case, the anterior muscles are necessarily in a state of tension: this completely counter-balances the relaxation of the others, and, therefore, there is nothing whatever gained. It is certainly much best to allow the leg to be in a state of moderate flexion, such as we assume when asleep, and which appears to be the most natural.

7. The apparatus just described, produces on the fragments a twofold action: 1st, by a kind of side walls formed by the splints, it prevents their displacement laterally, and from this circumstance alone, is fully sufficient for the retention of transverse fractures: 2dly, the pressure of the rollers, splints, and bolsters, if these be applied with sufficient tightness, prevents the lower fragment from mounting on the upper one, and thus preserves the natural length of the limb. Hence its advantages in oblique fractures; and, as the powers of displacement are weaker here than in the thigh, this apparatus, is in general, sufficient to counteract them.

8. It is true that cases do sometimes though rarely occur, where, in consequence, of being irritated by splinters, or the points of the fractured bone, or acted on by some other causes which make them contract, the muscles overcome the resistance of the apparatus, and make the fragments overlap. Under such circumstances, permanent extension affords here the same advantages as in fractures of the thigh.

9. Most authors, to obtain the desired end in such cases, recommend means calculated to act on the thigh. Thus, Manne proposes the use of his glaussocome. Desault, under such circumstances, effected his purpose by the apparatus described in the following case.

§ II.

10. Case II. Pierre Bejol, aged thirty-seven, of a strong and vigorous constitution, fell, as he was carrying a heavy load, over a beam which lay in his way. His leg was fractured towards its lower part; he was lifted up and carried home, where a surgeon, by making unskilful efforts at reduction, gave him extreme pain.

A roller and a kind of round splint applied to each side of the limb, forming the whole of the apparatus, and not being sufficient to retain the fragments, soon allowed them to overlap each other nearly two inches. The pains continue; a considerable swelling appears around the fracture; the patient is greatly agitated; he is brought to the Hotel-Dieu, where, from the deformity of the limb, Desault was satisfied, at first sight, of the existence of a fracture; on a more attentive examination, it was discovered to be complete and very oblique.

The muscles being tense and in a state of violent contraction, drew the inferior fragments very forcibly upwards; these were finally, however, by means of well directed efforts, brought into perfect contact, with the superior fragments: the difficulty now lay in maintaining this contact. The age of the patient, his strength, and the almost convulsive state of the muscles, gave reason to apprehend that a displacement was about to occur. An attempt was made to prevent this in the following manner.

The patient being laid on a bed properly prepared,

1st, The foot and the leg above the ancle, were covered by a bolster or compress, round which was passed a strong roller intended for the purpose of making extension. The ends of this roller, being left free, were carried, one on the outside, and the other on the inside of the limb.

2dly, Below the tubercle of the tibia was placed another bolster, surrounding the leg, and on this, was secured another roller for the purpose of counter-extension. The ends of this roller, after crossing under the knee, were left hanging loose one on each side of the limb.

3dly, The two rollers being thus arranged, while the assistants, still continued to make extension, the surgeon applied successively, and in the order already mentioned, the compresses, the bandage of strips, and the bolsters.

4thly, He then took two splints with notches in their lower ends, of the same breadth with the splints already described, but long enough to reach, each of them, from four inches above the knee to the distance of four inches beyond the sole of the foot. One of these was applied on the outside and the other on the inside of the leg.

5thly, The surgeon then taking hold of the two ends of the upper roller, drew them over the upper ends of the corresponding splints, while an assistant crossing the two ends of the lower roller under the sole of the foot, drew the external end over the lower extremity of the internal splint, and the internal end over the lower extremity of the external splint. Carrying them, then, up along each side, he brought them, at the middle of each splint, to meet the ends of the upper roller, to which they were firmly secured by knots, so as to make extension at the foot, and counter-extension at the knee. The two fragments, being drawn by this apparatus, the one down and the other up, could not again overlap.36

On the same day the patient was bled copiously; a low diet was prescribed; some diluting drinks were administered; and the whole apparatus was frequently wet with vegeto-mineral water.

Next day, fever; restlessness; blood-letting repeated; the extending rollers, having become relaxed, were tightened. Third day, evidently better. Fifth day, a new application of the apparatus; some swelling of the foot; a few small blisters on the leg; these were opened and dressed with cerate spread on linen. Eighth day, the patient easy and tranquil; a little shortening of the limb; a third application of the bandage. Twelfth day, bilious symptoms appear. Thirteenth day, an emetic given in solution; symptoms decline. Twentieth day, the fractured limb in a favourable state; the roller for extension laid aside; that formerly described employed in its place. Thirtieth day, an appearance of consolidation. Thirty-fourth day, bilious symptoms recur; further evacuations. Forty-third day, consolidation perfect; scarcely a vestige of the fracture remains. Exercise is repeated for several days. Fiftieth day the natural strength and motion of the part completely restored.

11. The general end to be answered by every bandage intended to retain a very oblique fracture of the leg, is evidently, 1st, to hold the knee up, and with it the superior fragments; 2dly, to draw the lower fragment down: from this twofold effect arises a twofold resistance diametrically opposed to the powers of displacement, which are; 1st, the slipping down of the trunk, which pushes the thigh before it, and with it the upper fragments of the leg; 2dly, the action of the muscles of the leg, drawing the foot upwards, and the lower fragment along with it.

12. But, if to these indications we compare the bandage described in the foregoing case, we will perceive that they are perfectly fulfilled by it. Indeed the splints forming a kind of pullies which change the direction of the rollers, we must count on the action of these rollers only from the part of the limb which they surround, to the ends of the splints over which they are reflected: whence it follows, that the two ends of the upper roller, reflected over the superior extremities of the splints, cannot be drawn down along each of these splints, without that part of the rollers, which reaches from the leg to these extremities, being drawn up, and with it the knee and the upper fragment. In like manner, the ends of the lower roller cannot be drawn up towards the ends of the upper one, without those portions of them which run from the sole of the foot, being drawn down and pulling the foot and the inferior fragments along with them.

13. Hence it follows, that by tying on each side, one end of the upper roller to the corresponding end of the lower one with sufficient tightness, the two indications above laid down (12) are accurately fulfilled.

14. But, in general, the common bandage is sufficient, as I have already mentioned, even in cases of oblique fractures, to prevent the ascent of the lower fragments on the upper ones. Desault never employed any others in the last years of his practice, and it was only in cases of extraordinary disposition to muscular contraction, that he ever had recourse to the second kind. By means of the common apparatus, he was able to prevent the overlapping of the fragments from forming any protuberance on the anterior and internal part of the leg.

15. We must acknowledge, however, that this apparatus is liable to the same objection with most others intended for permanent extension. The roller placed below the knee, for the purpose of counter-extension, surrounds almost all the muscles, which tend to make the inferior fragments overlap the superior ones, by drawing the foot upwards. By pressing on and irritating these, it favours, and even excites their contractions, and, by that means, gives rise to a shortening of the limb, the very accident which the apparatus is intended to prevent. This inconvenience induced Desault, in a particular case, to substitute to the preceding apparatus, that used for permanent extension in fractures of the thigh.

MEMOIR XV.

ON THE DIVISION OF THE TENDO ACHILLIS.

1. It might be supposed that a work on diseases of the soft parts, would be a more proper place for this article, than the present one, where my express object is to treat of affections of the hard parts. What induces me to insert it here is, the analogy which exists between a division of the tendo Achillis and a fracture of the os calcis, the light which the treatment of the one throws on that of the other, and the example of the celebrated Petit, who, in his work on diseases of the bones, speaks also of this division.

§ I.

OF THE CAUSES AND VARIETIES.

2. The division of the tendo Achillis is the result, either, 1st, of the action of a cutting instrument; or, 2dly, of muscular action: hence two very different modes of its production, the one by a wound, the other by a rupture. The first is not a very rare accident, because the projection of the tendon exposes it oftentimes to the stroke of external bodies: the second, though but little noticed by the ancients, has been frequently observed by the moderns, since their attention was called to it by Petit.

3. The manner in which the division is produced by a wound, has nothing particular in it; that by a rupture, takes place in the following manner. A man leaps over a ditch, but his spring or exertion is too weak; he reaches the opposite bank only with the ends of his feet: the line of gravity not falling on the ground, the weight of the body throws the feet into a state of violent flexion, the muscles contract with great force, to prevent a fall backwards, and, at that instant, the tendon is ruptured, in consequence of being drawn downwards by the violent flexion of the foot, and upwards by the effort of the muscles: hence it appears that Petit was deceived with regard to the mechanical cause of the rupture, which he considered as taking place at the moment of the patient’s alighting on his feet, when, as he said, the tendons were surprised, so to speak, into a state of too great tension. It is easy to apply the principles of this particular case to others that may happen, and where the position may not be the same; such as, when we leap on a table, &c. Sometimes slighter efforts have produced the effect; and, as Louis observes, dancers have sometimes ruptured the tendo Achillis by making a powerful exertion on the point of the foot, as well as by other motions.

4. Divisions produced in the first mode, may be situated in any part of the tendon. Those produced in the second, occur more particularly about its middle: to that part the effort or strain is most forcibly determined, and there the resistance is the weakest. The rupture of the tendon may, according to Petit, be either complete or incomplete; but, if we consider the simultaneous contraction of the gastrocnemii and soleus muscles, and the intimate manner in which their two tendons are united at a considerable distance above the heel, it will be difficult to conceive how these tendons can be ruptured separately. With regard to divisions produced by cutting instruments, the case is different: there, the weapon may pass half way through the tendon either from behind or laterally; and perhaps divisions of this kind are much more frequently incomplete than otherwise, in consequence of the great resistance of the tendinous fibres.

§ II.

OF THE SIGNS.

5. The superficial situation of the tendo Achillis, always renders the diagnosis of its division easy. It can be rendered difficult only by the occurrence of a considerable swelling, an accident that rarely happens. If there be an external wound, the depth to which the instrument has penetrated, and the possibility of sometimes feeling the ends of the tendon between the edges of the wound, are the first evidences of its division. If, on the other hand, the tendon be only ruptured, then at the moment when the rupture happens, a report is heard by the patient, not sharp, and like the crack of a whip, as is said to take place when the plantaris muscle is ruptured, but more dull and flat, according to the account given to Desault by a patient, whom he interrogated on the subject.

6. In either case, there occurs suddenly, if not an entire inability, at least, an extreme difficulty in either standing or walking: hence the patient falls, and is unable to rise again; but, in divisions that are only partial or incomplete (4), this sign does not occur. Between the divided ends of the tendon there exists a depression sensible to the touch. This depression is increased by the flexion of the foot, but diminished and even entirely removed by its extension.

7. The patient can spontaneously flex the foot, none of the flexor muscles being affected, and this flexion may be carried even beyond what is natural, because the divided tendon forms no obstacle to it behind. Spontaneous extension is also practicable, in as much as the peroneus longus, tibialis posticus, &c. which remain uninjured, are capable of producing that motion. Some have alleged that the calf of the leg must be increased in size by the swelling of the gastrocnemii and soleus muscles, in consequence of their state of contraction; but modern experience has shown, that there is but little reliance to be placed on that appearance.

§ III.

OF THE PROGNOSIS.

8. Divisions of the tendons are not in general dangerous. These organs, being insensible in their nature, are not painful when ruptured, as is proved both by experiments on living animals, and by the observations of surgeons who have had such affections under their care, more particularly of Monro, who experienced the accident in his own person. No inflammation supervenes, and if a swelling be sometimes the consequence, it is in general soon dispersed, leaving behind it nothing serious.

9. Whence arose then the exaggerated fears of the ancients respecting injuries of this kind? Doubtless from an opinion which was then entertained, that tendons and nerves were of the same nature. Hence the severe pains, the convulsions, and even death itself, which, according to them, frequently happened, and was always to be apprehended, as the consequence of injuries done to these organs. Lamotte, among the moderns, still entertained these prejudices, when, in speaking of affections of the tendo Achillis, he said, “So dangerous are they in their consequences, that they can seldom be brought to a favourable termination.”

10. Doubtless the unskilful treatment, employed by the ancients, in cases of this kind, the use of the bloody suture without proper means to retain the parts in a suitable situation, the abuse of irritating remedies applied externally, the imprudent administration of oily substances, and, still more, the motions of the patient, contributed not a little to the production of those accidents, which no longer occur in the practice of the moderns, since the nature and treatment of the disease is better understood. It has been proved, by late observations, that the division of the tendo Achillis is apt to produce some diminution in the size of the affected leg. But this soon disappears, nor does it, indeed, even occur, if, by a proper application of the bandage, a speedy union of the divided part be obtained. The patients of Desault never experienced it.

§ IV.

OF THE INDICATIONS OF CURE.

11. That I may present, in order, what I have to offer on the treatment of the division of the tendo Achillis, 1st, I will lay down, with precision, the indications of cure that arise out of this division: 2dly, with these indications I will compare the means used by different authors, by which the insufficiency of almost all of them will be demonstrated: 3dly, by showing the relation or correspondence that subsists between these indications, and the apparatus employed by Desault, I will prove that it fulfils them sufficiently, and is, therefore, to be preferred to every other.

12. To bring the edges of the division into contact, and to retain them so, are here, as in other simple wounds, the two general principles of treatment. The first of the principles presents an easy indication; it is only to extend the foot forcibly on the leg. The indications that arise out of the other, are more difficult to be fulfilled.

13. To form a proper idea of these, let us call to mind what it is that prevents the contact of the divided ends. As far as relates to the lower end, it is the flexion of the foot on the leg, and with respect to the upper one, the contractions of the gastrocnemii and soleus muscles, which are not now opposed by the continuity of the tendon. Therefore, 1st, to keep the foot permanently extended; and 2dly, to oppose the action of these muscles, are the two general indications or objects of every apparatus destined to retain the two ends of the tendon in contact.

14. But, the action of the muscles may be opposed in different ways; 1st, by keeping the muscles themselves in a state of relaxation. This relaxation may be easily effected, as far as relates to the gastrocnemii, in consequence of their insertion into the posterior part of the condyls of the os femoris: it is sufficient, for this purpose, to keep the leg half-bent on the thigh: 2dly, by a judicious and well directed compression made on the muscles. I say judicious and well directed, because it ought to bear chiefly on the fleshy portion, and not on the tendon, otherwise it will depress its divided ends, destroy their contact, and make them unite, not with each other, but with the adjacent parts, and thus produce considerable lameness. At the same time that care is taken not to depress the divided ends, these ends must not be permitted to move from side to side, a kind of displacement which may readily occur, in consequence of the hollow or depression situated on each side of the tendon. But, the only expedient to attain this twofold purpose, is, to place in these hollows, some soft substance, lint, for example, which may project sufficiently to protect the tendon behind, and to retain it laterally.

15. This compression, that ought to be made by the bandage, appears to have escaped all writers, as none of them have given it a place among their means of cure. Yet, do we not plainly perceive, that, by confining the muscles, impeding their contractions, and reducing their irritability by its long continued use, it must tend to prevent the superior end from being drawn upwards and thus separated from the inferior one? Will not compression, in this case, be similar to the effect of the uniting bandage, in transverse wounds, where the great number of circular casts which cover the limb, are particularly intended to weaken muscular action, analogous to what takes place in hare-lip, where the compresses do as much good by compressing the muscles, as by bringing together the edges of the divided lip? But further, besides reducing the force of the muscles, does not this compression serve to prevent the swelling of the limb, an effect almost inevitably resulting from its state of rest and deficiency of action? So far, then, from being, as Louis says, one of the inconveniencies of the first bandage of Petit, it constitutes one of its principal titles to a preference among practitioners.

16. It appears from what has been just advanced (13...15), that the following are the three ends to be attained by every bandage, intended to retain the divided ends of the tendo Achillis in contact; 1st, the immobility of the foot in a state of permanent extension on the leg; 2dly, the immobility of the leg, in a state of semiflexion, on the thigh; 3dly, a judicious and well directed compression made on the whole leg and foot, but bearing on the tendon with only sufficient force, to keep it from moving backward or laterally. Let us compare the methods of authors with these indications.

§ V.

OF THE DIFFERENT METHODS OF CURE.

17. The treatment recommended by authors may be reduced to three general methods. The first consists in rejecting all artificial aid, and leaving the cure to nature and the position of the limb. To the second belongs the use of sutures, intended to retain the edges of the division together. The third includes the different kinds of apparatus employed for the same purpose.

18. First method. Chronological order places this method after the others. But this order must be disregarded by him, whose object is things rather than time. The history of the sciences calls sometimes for the approximation of distant periods, and, at other times, for the separation of those already approximated.

19. Several practitioners, in France and England, have lately proscribed the use of all external means. Pibrac and Dupouy were of opinion, that the mere precaution of the patient not to flex the foot, assisted by constant rest, was sufficient. Hoin and Gauthier mention many cases in confirmation of this doctrine. M. J. Rodbard, surgeon at Ipswich, having ruptured his own tendon about three inches above the heel in leaping over a little rivulet, instead of confining himself to bed, continued in the exercise of his profession. He walked every day, without any other precaution than that of not flexing the foot, and five years afterwards, he was able, as he mentions, “to walk, run, mount or alight from his horse, without pain, in a word, the affected leg performed its functions as well as the other one.” We have an account of a patient who was cured without a bandage by A. Petit.

20. Was there indeed a true rupture of the tendon, in all these cases, particularly in those where the patients continued to walk as before the accident? Most of the cases which we have seen prove the impossibility of either standing or walking (6). But, admitting that they were ruptures, are we authorized to pursue the mode of treatment there adopted? Certainly we are not. None of the indications formerly mentioned (16) is there fulfilled. What is there, under such circumstances, to prevent an involuntary motion from destroying the contact of the divided ends, by forcibly flexing the foot and extending the leg? The limb is not subject to any compression. Should such an accident happen, the cure must necessarily be tedious. Besides, if the ends be separated, a reunion cannot take place, except by an intermediate substance, which, by filling up the vacant interval between them, must lengthen the tendon. In consequence of this, the muscles will be impeded in their contractions, and the foot in its motions, as Desault has oftentimes observed in animals, which he left to themselves, after having divided the tendo Achillis. Thus, in a fracture of the rotula, the motion of the limb is very much impaired, when the ligamento-cartilaginous substance which unites the fragments is too long.

21. Hence it follows, that here, in like manner as in other ruptures of the tendons, art must assist nature, because without the former the powers of the latter will be insufficient.

22. Second method. The ancients pursued a course not less uncertain, and much more dangerous. Sutures, sanctioned by general custom, were extended to wounds in the tendons, and were even more especially employed in such cases, because the tendinous end being drawn forcibly and greatly displaced by the contraction of the fleshy portion in which it terminates, it was deemed necessary to oppose to this force a greater resistance.

23. What useful end was attained by this practice? Muscular action was left perfectly free; and the only thing done was an attempt made to resist its effect. But, in a short time the tendinous ends, in consequence of being forcibly stretched by the contractions of the muscles, either gave way at the points where the stitches were introduced, or, in case they did not give way, became swollen, painful, and inflamed, in consequence of the violent distension which they suffered: hence the serious affections produced by such treatment (9 and 10).

24. The ancients, then, were mistaken, with respect to the indications in this disease, which are, not to resist muscular contraction left free and unimpeded, but to check and prevent this contraction, by the means formerly pointed out (16). It is a principle generally acknowledged at the present day, that sutures ought not to be used as a mean of approximating divided parts, but only to keep the edges of parts already approximated in perfect contact. But, in the present case, the means of approximation being sufficient for the purpose of exact contact, sutures are altogether unnecessary. This, however, does not hold true in every case, though certain practitioners, who have too generally rejected the use of sutures, contend that it does. Finally, however, these means have been excluded from the treatment of the division of the tendo Achillis, and the doctrine of the Academy of Surgery, though erroneous in many other cases, has established, with regard to the present one, the true practice.

25. Third method. It is to the celebrated Petit that we are indebted for that method of treating the division of the tendo Achillis, which consists merely in position maintained by apparatus. Having ascertained that the extension of the foot brought the fragments into contact, he conceived the idea of continuing this extension throughout the whole treatment, for the purpose of continuing the contact also. This was a happy idea, the simplicity of which recommended it to practitioners, and which, being once discovered, has formed the common basis of all the numerous processes devised since by different authors.

26. When we consider the action of these several processes, and compare it with the indications formerly laid down (16), we may divide the processes themselves into three general classes. Thus, some of them fulfil only the first and third of these indications, namely, the permanent extension of the foot, and a regular compression made on the leg; others fulfil only the first and second, the latter of which consists in keeping the leg constantly flexed on the thigh; while those of the third and last class, fulfil the first indication only. This manner of classing the processes, will shorten the consideration of each of them individually, since it is evident that each class is chargeable with one general inconvenience, namely, that of being deficient with respect to one or two of the leading indications. I shall examine nothing, therefore, but the disadvantages peculiar to each.

27. To the first class belongs, almost exclusively, the first bandage invented by Petit. It is formed by a long compress, placed longitudinally behind the leg and foot, and secured by a roller applied regularly on these parts. The two ends of the compress, being reflected back, are then knotted together behind the leg so as to extend the foot. This expedient is simple and ingenious, and would be preferable to all others, were it not that, besides the charge of not fulfilling the second general indication (16), it is further liable to the following objections: 1st, the compression which it makes is injudicious and ill directed, because it bears not only on the fleshy portion of the leg, but also on the divided tendon, which being more projecting and therefore more exposed, has its two ends pressed down and separated: 2dly, in some cases, it does not maintain the extension of the foot with sufficient certainty: 3dly, it does not prevent displacement in a lateral direction.

28. To the second class belong, 1st, the celebrated slipper of Petit, substituted by that author for his first bandage; this machine was composed of a slipper fixed to the foot, of a knee-piece37 secured on the lower part of the thigh, and of a strap running from the one and fastened to the other, to extend at pleasure the foot on the leg, and to flex the leg on the thigh: 2dly, the bandage of Duchanoy, made in imitation of the preceding apparatus, and consisting of a simple sock surmounted by a roller, which running along the back part of the leg, was fastened to another roller applied round the lower part of the thigh. Besides the general objection of not at all fulfilling the third indication (16), these processes are liable also to the following ones; 1st, they fatigue the toes by the constant pressure of the slipper and the sock, as Monro experienced in his own person, to such an extent that he was unable to support their use; 2dly, the slipper is quite too complicated, and is therefore seldom at hand when wanted. The apparatus of Duchanoy, does not possess sufficient solidity and steadiness.

29. In the third class are included, 1st, the first machine of Monro, formed of a slipper similar to that of Petit, surmounted by a strap of leather, which was to be fastened by a buckle to a kind of guetre or spatterdash, fixed on the upper part of the leg; 2dly, the second apparatus of the same author, subject, like the other, to several inconveniences; 3dly, the simple apparatus of Schneider, who rested satisfied with maintaining the extension of the foot, by a splint placed anteriorly. Besides various other objections to them, these are all chargeable, alike, with the radical fault, of not fulfilling the second and third indications (16).

30. From this comparison of the indications (16) with the means destined to fulfil them, it appears that there were material defects on the part of the latter. Let us examine whether or not that of Desault was better calculated for the purpose. It is, so to speak, nothing but a modification of the apparatus of Petit (27), but such a modification as amounts to an improvement in principle, and entitles it to be called the apparatus of Desault.

31. The pieces which compose it are; a compress two inches broad, and long enough to reach from the lower part of the thigh to the distance of four inches beyond the foot; a roller five or six yards long and two inches wide; a sufficient quantity of lint; and two long graduated compresses.

32. Every thing being ready;

1st, An assistant supports the foot and leg, the former in a state of great extension, and the latter half-flexed: another assistant supports the thigh, grasping it about its middle.

2dly, If there be a wound of the integuments, a little lint wet with vegeto-mineral water is laid directly over the division of the tendon; if it be a simple rupture, this precaution is unnecessary. Under the foot, up behind the leg, and the lower part of the thigh, is then extended the long compress, which is to be secured in that situation by the hands of the assistants.

3dly, The hollows situated at the sides of the tendo Achillis, are then filled up with pledgets of dry lint, surmounted by the two long graduated compresses, which retain the pledgets, and must project a little beyond the tendon, because they are liable to be rendered flat by pressure.

4thly, The surgeon now taking the roller, makes at first several circular turns round the toes, fixing the long compress there, the end of which, being reflected over these first casts, is secured by a few additional ones which cover the whole foot, and are afterwards directed obliquely above and below the division, round which is formed a kind of figure of 8, that brings the edges of the wound into perfect contact. If there be no wound of the integuments, it is necessary to take care, lest the skin interposing between the divided ends of the tendon, should separate them, and thus prevent their reunion. Ascending, then, by circular casts, along the whole leg, and even to the lower part of the thigh, the surgeon there turns down the upper end of the long compress, and securing it by a few more circular casts, finishes the application of the roller.

5thly, The apparatus being thus applied, and the extension of the foot and the flexion of the leg firmly secured by it, the leg is then placed on a pillow or bolster, one side of which corresponding to the angle which the leg forms with the thigh, assists in keeping it half-flexed.

6thly, Should the long compress prove insufficient to keep the foot extended, or should it, by becoming relaxed too soon, render frequent reapplications of the apparatus necessary, (circumstances which rarely happen when the bandage is well applied), a splint placed anteriorly, as was the case in Schneider’s apparatus (29), completely remedies the defect.

33. On comparing this apparatus with the indications formerly laid down, in the present disease (16), we find it evidently calculated to fulfil them with great exactness. 1st, The extension of the foot is permanently secured, both by the long compress, and by the splint when it is employed: 2dly, the same compress, aided by the bolster or pillow placed under the leg, maintains the flexion of the leg on the thigh: 3dly, The muscles are effectually compressed; their action is impeded in part by the compression of the circular bandage, which does not bear on the tendon, in consequence of the bolsters of lint placed on each side of it: these bolsters prevent the tendon both from moving laterally, and from being depressed: hence it follows, that the action of the circular bandage is precisely conformable to the principles already established (14 and 15); and that the whole of the apparatus, taken together, fulfils perfectly all the indications (16); this is an advantage not to be derived from any of the forms of apparatus used by preceding authors.

34. This apparatus is in no degree complex or troublesome. Simple and easy, it requires nothing for its construction but what the surgeon can easily obtain, and what he can even himself prepare. There exists a great analogy between it and the bandages which Desault used for the reunion of transverse wounds, and for fractures of the rotula and the olecranon. A truly great man does not estimate his merit, by the number of processes which he invents; he well knows that the perfection of art consists in producing numerous effects by few and simple means.

35. We will confirm, by two cases, the principles laid down in this memoir. One of these relates to a division of the tendon, connected with a wound, and was reported by Bezard; the other by Manouri, and relates to a simple rupture of the tendon.

Case I. J. B. Lavigne, aged thirty, as he was going down into a cellar without light, struck his leg against the edge of a sharp saw, which completely divided the tendo Achillis. The patient was immediately carried to the Hotel-Dieu. The wound of the integuments was transverse, two inches long, and had its edges but slightly separated from each other. The ends of the tendon, in contact during the extension of the foot, were separated two inches when it was flexed.

The usual apparatus was applied (32), and the limb placed on a bolster, in a position favourable for the relaxation of the posterior muscles.

In the evening, wound painful; pulse raised; a copious blood-letting; low diet. Next day, more blood taken away; antiphlogistic regimen, which was continued for several days, till the symptoms were gone: no troublesome accident occurred. Tenth day, the apparatus taken off; the wound partly healed; the apparatus reapplied, and continued till the twentieth day, when the perfect reunion of the parts rendered its further use unnecessary. From this time the patient began to walk on crutches. Thirty-sixth day, could walk well without his crutches. At this period, a small abscess occurring in his heel, induced him to remain in the Hotel-Dieu two weeks longer, when he was discharged perfectly cured.

Case II. M. Delp, leaping with some of his young companions, ruptured the tendo Achillis, about two inches above the os calcis. Both standing and walking became instantly impracticable: the patient falling down, was taken up, carried home, and from thence to Paris, where he arrived in the evening. Desault being immediately called to him, found him affected with all the signs of a division of the tendon; such as, a hollow between its divided ends, which was increased by the flexion of the foot, diminished by its extension, &c. The usual apparatus was immediately applied, and as the patient felt but little pain, only a moderate blood-letting was prescribed. Next day, no alteration in the treatment; antiphlogistic regimen; low diet continued for some days, when the patient was permitted to return to his usual mode of living. Ninth day, apparatus removed for the first time: a slight separation of the ends of the tendon; and a wrinkle in the skin interposed between them: a new application of the bandage, taking care to free the integuments from wrinkles. Twelfth day, a relaxation of the rollers; a third application of the bandage: every thing found in a good state; but, the patient being, from sprightliness, too much inclined to exert himself, a splint was applied anteriorly to prevent the extension of the foot. Seventeenth day, a fourth application of the apparatus, which was not moved again till the thirtieth. At this period, the reunion was somewhat advanced: fortieth day, almost complete. Fiftieth day, the patient was permitted to leave his bed, and take very gentle exercise, which he continued to increase gradually, till the sixtieth day, when he was discharged cured. Doubtless the tediousness of this case was owing to the slight separation which existed for some time between the fragments.

MEMOIR XVI.

ON THE FRACTURE OF THE OS CALCIS.

§ I.

1. The os calcis, being a short and thick bone, has such a power of resistance, that it is but seldom fractured. Such an accident does, however, sometimes occur, and may arise from two causes, 1st, the action of external bodies, which is rare: 2dly, the contraction of the gastrocnemii and soleus muscles, from which it almost always proceeds. Thus, the rotula is more frequently broken by the action of the extensor muscles, than by blows received on the bone from without: there is, however, this difference between the effects of muscular contraction in these two cases, namely, that in the former, the rupture of the tendo Achillis is common, and the fracture of the os calcis very rare; whereas in the latter, on the contrary, the rotula is oftentimes broken, while the tendon of the extensors remains almost always sound. This phenomenon is explained by the difference between the thickness of the two bones, between the length of the two tendons, and between the power of the causes.

2. Be the cause of the fracture what it may, it generally occurs in that portion of the os calcis, called its great tuberosity, which projects behind the astragulus, which corresponds above and below to a large quantity of cellular membrane, inwardly to the great groove of the bone, externally to some ligamentous attachments, and behind to the insertion of the tendo Achillis.

3. It is known, 1st, by an evident inequality under the heel: 2dly, by an elevation, sensible to the touch, of the posterior fragment above its usual level: 3dly, by an almost entire inability either to stand or walk: 4thly, by severe pain being the inevitable consequence of moving the foot: 5thly, by its being practicable to increase the displacement by flexing, and to diminish it by extending the foot: 6thly, by the facility with which the posterior fragment may be moved in every direction by taking hold of it with one hand, and steadying the foot with the other: 7thly, by a swelling more or less considerable, which frequently appears around the divided surfaces.

4. The ancients gave in general an unfavourable prognosis respecting this kind of fracture. Hippocrates was apprehensive of some injury being done to the surrounding parts. Pare considered the case mortal, on account of the laceration of numerous vessels which are connected with the bone. Most of the moderns adopt these principles, not for the foregoing reasons, but on account of the vicinity of the accident to the joint of the foot. The practice of Desault cannot throw much light on this subject, as he never had more than one or two such cases of fracture under his care; but the analogy of other fractures, situated in the neighbourhood of joints and even extending into them, induces us to believe, that, if properly treated, fractures of the os calcis will terminate as favourably as those of other bones.

§ II.

5. If we attend to the signs just mentioned (3), we will perceive that they almost all result from the displacement of the fragments. But, whence arises this displacement? As far as the anterior fragment is concerned in it, it arises from, and is increased by, the flexion of the foot; and, as far as relates to the posterior one, it is to be attributed to the contraction of the muscles attached to the tendo Achillis, which is itself inserted in that fragment. Hence it follows, that the apparatus intended to prevent this displacement, ought, 1st, to keep the foot permanently extended on the leg: 2dly, to prevent the action of the muscles, by keeping them in a state of habitual relaxation by means of the constant flexion of the leg on the thigh, by making on those whose contractions are dreaded, such a regular and well directed compression as may disqualify them for contracting; and, lastly, by placing behind the posterior fragment some resisting substance, to prevent it from rising upwards.

6. If to these indications we compare Desault’s apparatus for a rupture of the tendo Achillis, as described in the preceding memoir, we will readily perceive 1st, that it perfectly fulfils that indication which relates to the anterior fragment; 2dly, that that one which relates to the posterior fragment will be equally well fulfilled by the half flexed state of the leg, by the compression made on the muscles, and by a thick compress, not very broad, laid transversely above the fragment, secured by the long roller, and afterwards by a circular bandage, which must form here, as in the case of a fractured rotula, a kind of figure of 8 around the fracture. This compress is the only modification of the apparatus requisite to accommodate it to the particular case now under consideration.

7. In applying the figure of 8 bandage here, as well as in the case of a fractured rotula, to prevent the ascent of the fragment, it is necessary to use the utmost care to free the integuments from wrinkles both above and below the fracture, lest by getting between the fragments, they might keep them asunder, and thus impede their reunion.

8. Desault used to relate in his lectures, the case of a woman whom he had formerly seen receiving a fracture of the os calcis, by falling from a great height. I cannot state the case fully, because I am not in possession of all the facts. The following one however drawn up during the first years of Desault’s practice in the Hotel-Dieu, will furnish an example of his mode of treatment.

Case. A man, likely to be arrested by some one who pursued him, leapt from a window nearly twelve feet high. In lighting, his feet struck on a beam which lay in his way, in such a manner, that the fore part of them only was supported. He made an effort to recover his equilibrium, but as the line of gravity of his body had nothing to rest on, he fell backwards, rose in order to make his escape, but fell a second time unable to rise again.

When assistance came to him, he complained of a severe pain in his heel, and said, that on falling, he had heard a considerable report. He was taken up, and assisted in walking to the Hotel-Dieu, where he did not arrive without pain, being able to bear only on the point of the diseased foot, and suffering greatly if he attempted to put his heel to the ground.

From the signs mentioned (3), Desault perceiving that there existed a fracture of the os calcis, made arrangements for reducing it. This he did by extending the foot on the leg, and drawing down the exterior fragment from the elevation to which muscular contraction had raised it, so as to bring it into perfect contact with the body of the bone. He then applied the common apparatus for a rupture of the tendo Achillis, with the modification already pointed out (6).

In the evening venesection was prescribed: the patient experienced sharp pains at the place of the fracture; a slight swelling occurred at the ends of the toes; an anodyne was prescribed. Next day, evidently better: venesection again. Fourth day, the patient is allowed to return to his usual regimen. Eighth day, apparatus removed for the first time; fragments in contact. Fifteenth day, a second application of the bandage. Nineteenth day, bilious symptoms. Twenty-first, an emetic given in solution. Thirty-second day, further evacuations: apparatus renewed. Forty-seventh day, consolidation complete. A stiffness remained in the part for some time, but this was gradually removed by exercise.

MEMOIR XVII.

ON COMPLICATED LUXATIONS OF THE FOOT.

§ I.

1. Complicated luxations of the foot, like complicated fractures, show themselves under such a variety of forms, are accompanied by so many peculiar affections, and so many different circumstances are connected with them, that it would be difficult to lay down rules applicable to their treatment in all cases. On this subject, indeed, art is in possession of certain general principles, liable however to numerous exceptions and modifications. In the treatment of such cases, who can fix the limits between reduction, and amputation or extirpation? Who can point out, with precision, where the one ceases to be useful and becomes hazardous; while the others constitute the only resources of art? Experience and talents alone are capable of deciding on these points, and that only in the chambers of the sick. It is, therefore, less by precept than example that practitioners ought to be instructed here.

2. To furnish suitable examples on this head constitutes my only object in the present memoir, which will consist of the histories of a few cases, with such inferences and remarks as the occasion may seem most naturally to suggest. Here the practice of a great master, varying his means with the varying forms of disease, will serve as models to those who may meet with similar cases. Our experience is composed of the facts which we receive from reading, as well as of those derived from observation. Who would have a right to call himself a surgeon, if he had no other title to that name, but such as resulted exclusively from his own personal observation?

3. However difficult it may be, as already observed, to speak in general terms, on the present subject, we may yet assert with safety, that authors have greatly exaggerated the danger of complicated luxations of the foot. Terrified at the extent and unpromising appearance of the accidents, these writers have lost that confidence in the powers of nature which we never ought to abandon. They have taken up an opinion, that luxations of the foot, differing in their symptoms from other luxations, require also a different mode of treatment; that reduction, by perpetuating the accidents of the case, must prove fatal, and that amputation ought to be adopted as the only resource. Cases do certainly at times occur, where a doctrine different from this would be fatal in its effects: such are those terrible lacerations, where the foot is entirely separated from the leg, except some shreds of flesh with a few tendons among them that still retain it.

4. But, provided the blood-vessels have escaped, and any hope of circulation and life in the part still remain, the success of reduction should always be first tried; and the following examples will show, what ought to be expected from this practice, when accompanied by skilful treatment.

§ II.

LUXATION OF THE FOOT, COMPLICATED BY A FRACTURE OF THE FIBULA, TIBIA, &C.

Case I. (The following case was collected by Leveille.) Abraham Genty, aged forty-three, a dealer in wine, as he was running along the street, slipped, and made a false step on his left foot, which turned with its external edge under him, and its internal edge upwards. He fell, luxated his foot, and fractured the fibula.

The patient was carried home, where a surgeon who was ignorant of his profession being called, did nothing but apply a cataplasm to the foot. In the evening the parts began to swell, and were extremely painful; fever supervened, accompanied with great restlessness. Third day, to a rapid increase of all the symptoms was added a delirium; blood-letting from the jugular vein was prescribed to no purpose; things continued to grow worse till the sixth day, when the patient was brought to the Hotel-Dieu, in extreme danger.

The following was then the state of the parts. A considerable swelling around the joint; a projection of the malleolus internus, with a depression underneath it; a preternatural direction of the tibia before, and of the os calcis, behind; a depression near the lower end of the fibula; a crepitation readily perceived, on moving the fragments; a large tumour on the outside of the foot: with a depression and mobility of the malleolus externus.

The luxation was immediately reduced. Extension made on the foot and leg brought the parts into their proper situations, where they were retained by means of the bandage for fractures of the leg, and four compresses well secured by the bandage. One of these compresses, being placed on the malleolus internus, another on the outside of the foot, a third on the anterior and lower part of the tibia, and the fourth under the os calcis, prevented these different parts from being again displaced.

As soon as the apparatus was applied, the pupils remarked with astonishment, that the restlessness of the patient ceased, that his pains were relieved, and his delirium disappeared; he expressed his surprise at the state from which he had just recovered, and was now able to give an accurate account of his fall. He was scarcely put to bed, when he fell into a tranquil sleep, which lasted three hours. For six days previously he had not slept a moment.

In the evening, the patient was free from pain, and perfectly tranquil. Diluting drinks were prescribed, with twenty-five drops of Hoffman’s anodyne liquor: the apparatus was wet from time to time with vegeto-mineral water: the patient slept well throughout the night.

Next day, the apparatus renewed: the parts perfectly in place: swelling diminished; same means continued. Sixth day, the anodyne discontinued. Tenth day, swelling still less; echymosis gone; a yellow colour in the skin, an evidence that resolution is going forward. Twentieth day, swelling gone.

Thirtieth day, the fracture of the fibula healed; that bone slightly separated from the tibia: the circular roller drawn tighter; and a thick compress placed on the external malleolus, to bring it to its proper place. Forty-fifth day, the apparatus for a fractured leg removed, and a simple roller substituted in its place: the motions of the foot painful and contracted; a small gangrenous spot appeared on the heel. Fifty-fifth day, the ulcer which proceeded from this spot healed: motions of the part more free and extensive. Sixty-first day, the patient able to walk without assistance, though not without pain.

5. It is difficult to find an instance where the advantages of reduction have been more remarkable than in the preceding one. The patient had passed six days in pain, extreme agitation, and uninterrupted delirium: the foot was reduced, and these unfavourable appearances instantly vanished, and were succeeded by a state of tranquillity. Alarmed by such a state of things, the ancients would doubtless have proceeded to amputation. Let us examine into the motives which led Desault to an opposite line of practice, and then inquire into the cause of the success with which that practice was crowned.

6. Had amputation been performed here, it must have been for one of the two following reasons; 1st, for fear of gangrene; or 2dly, to remove the unfavourable symptoms that existed. The first apprehension would have been quite visionary, in as much as all the blood-vessels were sound. Would the second consideration have been any better founded? It was perfectly obvious, that the unfavourable symptoms which existed arose from the tension and overstretching of the parts, in consequence of the preternatural position of the bones of the foot. The indication was evident. Replace these bones in their natural situations, the strained parts will then necessarily become relaxed, and all the troublesome and alarming symptoms cease with the cause that produced them. Experience confirmed the justness of this reasoning.

7. But the mere replacement of the parts would be of very little avail, if it were not permanently maintained, and followed up by a judicious mode of treatment. Without such treatment there would doubtless be reason to apprehend all that train of troublesome consequences, of which authors speak in such frightful terms, and which arise, not from the nature of the luxation, but from the manner in which the patient is treated. A loose apparatus, incapable of preventing displacement, would allow the bones to be deranged anew, and to produce again an overstraining of the parts, accompanied with pain, swelling, &c. Irritating local applications, such as camphorated spirits of wine, &c. would increase these pains; emollients which are employed in other cases would keep up the swelling.

8. It follows from what has just been said, that an opposite mode of treatment ought to succeed the reduction, and this we see was the case in the preceding instance. There, when the bones were once reduced, all new displacement was prevented, because the apparatus was so constructed, as to counteract the tendency of the bones to be displaced. The external edge of the foot, which had been turned outwards, was now pushed inwards by a thick compress; the same means served to push outwards the internal malleolus, which had received by the accident an inclination inwards, and to push the anterior part of the tibia backward, and the os calcis forward, both of which were displaced, as has been remarked, in contrary directions. Two strong splints fixed the lateral compresses, while the anterior and posterior ones were firmly secured by rollers. In the midst of all these resistances, the foot being necessarily immoveable, no new displacement could occur.

9. A suitable and judicious position, in which the foot, raised a little higher than the leg, was placed on a pillow forming an inclined plain, prevented swelling, while gentle compression, made by a bandage, contributed to the same end. This end was also further attained by the external topical applications. To relieve pain and remove congestion, were here, as in sprains, the two indications to be fulfilled. To these indications the spirituous and the relaxing applications formerly in use, are alike opposed. Vegeto-mineral water, on the contrary, fulfils them extremely well. Hence the necessity of keeping the apparatus constantly wet with that liquid.
