Dislocation backwards of the fiend of the fiuments on the dor sum of (he scapula, ike result of accident. — In this dislocation the arm Is Fig. Dislocation on the dorsum of the scapula. directed from above downwards, inwards, and forwards. The deformity of the joint is well seen by viewing it in front, where a deficiency is noted of the normal roundness of the articu- lation. When we look at the shoulder side- ways, the head of the humerus maybe seen to form a remarkable saliency behind the posterior angle of the acromion. In this dislocation the head of the bone is thrown on the posterior surface of the scapula immediately below the spine of this bone, and there forms a very re- markable protuberance, and when the elbow is rotated as far as practicable this protuberance moves also. The dislocated head of the bone may be easily grasped between the fingers, and distinctly felt resting below the spine of the scapula; the motions of the arm are impaired, but not to the same extent as in the other luxations of the shoulder, and the longitudinal axis of the humerus may be observed to run upwards, backwards, and to a point, evidently behind the situation of the glenoid cavity. In Guy's Hospital Reports * Sir A. Cooper has published a case of this species of dislocation, from which
