Note 62 — PART SECOND. OF PARTICULAR SURGICAL SUBJECTS. (continued 12)

[The bones, owing to falls, blows, or other external violence, are occasionally bent, with or without partial fracture. Within the last few years a considerable number of cases of this accident have been reported by American and European practitioners. The first regular account of it was published in 1810, by Professor Jurine of Geneva; and in 1821 a very able article on the subject appeared in the American Medical Recorder, from the pen of that distinguished surgeon, Dr. John Rhea Barton, of Philadelphia.

Simple bending is most common in the radius and ulna, though it is by no means confined to them. For obvious reasons it happens only in children, before the completion of the ossific process, or in whom there still exists a predominance of animal matter. In older persons the bones more readily break than bend. The diagnostic signs of the accident are, pain and deformity at the seat of the injury, loss of power in the limb, want of displacement of fragments, and absence of crepitation. The deformity consists in an unnatural curvature, which can be made to disappear under pressure and extension, but recurs, to a certain extent, when the limb is liberated. When attended with partial fracture, the symptoms are the same, excepting that, instead of a curvature, there is angular deformity opposite the seat of the accident. When the injury occurs in the forearm, and only one bone is implicated, extension generally produces no change in the appearance of the limb. The treatment, in both cases, is to be conducted upon the same principles as that of fractures. The attempts to remove the curvature by extension should neither be too violent nor long continued, otherwise they must prove injurious. Mr. Mantel of England, distinguished alike as an able surgeon and an accomplished geologist, thinks that the application of leeches and the usual antiphlogistic means should alone be trusted to when there is much pain and swelling, alleging that the action of the muscles will ultimately restore the limb to its natural form.—ED.]
