Note 33 — Chapter IV · PATHOLOGY

The beading may have the usual, rounded, smooth, knobby character. There may be, however, what one might term “angular beading,” the junction taking on a step-like form, as if the abutting ends of the cartilage and the bone were of unequal size and not well fitted to each other. The cartilage overtops the bone, so that on palpating the joint there is a precipitous fall as we run the finger outward from the surface of the cartilage, or a sudden elevation on palpating the rib from without inward toward the sternum.
