I have seen many instances of expansion of the articular ends of bones, especially of the inner condyle of the femur and of the head of the tibia, ensuing from a blow or other slight injury. ‘The gradual enlargement of the bone was accom- panied by tenderness in the part, by a slight increase of its heat, but by no change in the soft coverings. Local depletory remedies and counter-irritants were in such cases effective in restoring the part to a natural condition, as far as its sensations were concerned; but, as in other affections of bone, the morbid action very often recurred, and I have not in any instance clearly recognized a dimi- nution of the enlarged bone. I believe that a bone once enlarged by the expansion of its tissue will permanently remain so. ENLARGEMENT OF BONE WITH INDURATION OF ITS TISSUE. ; The enlargement of bone with induration is the effect of prolonged inflammation in its tissue; and, according to the observation of Mr. Paget, it appears that the lamelle of the inflamed bone are first separated and its cells widened; and that the lamellae become thickened, hardened, and consolidated together. As, in the original formation of bone, its solidity is owing to the formation of osseous con- centric laminz upon the insides of the Haversian canals, so, in disease, its induration is the effect of increased osseous formation within these canals, narrowing some of them and obliterating others. Accordingly, indurated 2 Plate 1, figs. 4, 5, 6.
