A practical treatise on fractures and dislocations . responding to the head. The capsule presented theappearance of a large sac with walls very much thickened at certain points. Inthe part corresponding to the superior margin of the glenoid cavity were a num-ber of superposed horizontal folds, of the size of a centimetre, and projectinginto the interior of the cavity; these folds divided it into two portions, an infe-rior one, corresponding to the old articular cavity, and a superior one, corre-sponding to the new one. The head could be abnormally moved in all directionswithin the capsule, and it appeared flattened above and behind and was denudedof its cartilage. On the level of the anatomical neck, the cartilage was wornout in places; in others it presented a velvety alteration, at which points it wasof a yellowish-gray color. The bicipital groove was very shallow. Panas and Angers1 have demonstrated upon the cadaver that the head of thehumerus could be dislocated upward above the acromio-coracoid vault withoutdestroying it.

A sudden pain was felt in the shoulder at the time, but after-ward the whole arm felt numb, although on touching it or on attempting to raiseit there was very acute pain. Six weeks after the accident there was a large,hard, slightly-irregular, rounded swelling about a fingers breadth in front ofthe right acromion and immediately to the outer sid
