In the adult, a fracture through the original line of junction of the superior epiphysis with the shaft of the humerus would be attended with nearly similar symptoms. In alluding to the injury in question, Sir A. C. observes, that in children it is the result of falls upon the shoulder. The signs of it are as follow : — The head of the bone remains in the glenoid cavity of the scapula, so that the shoulder is not sunken as in dislocation; when the shoulder is examined a projection of bone is perceived upon the point of the coracoid process, and when the elbow is raised and brought forward this projection is rendered particularly conspicuous. By drawing down the arm the prominence is removed, but it im- mediately re-appears upon ceasing to make the extension, and the natural contour of the shoulder is lost. All the movements of the shoulder joint are painful, and the patient cannot raise the arm unless by the aid of the other hand. The elbow is with difficulty withdrawn from the side, and the arm requires support. Sir A. Cooper adduces a case illustrating the above symptoms in a child aet. 10, who had fallen on the shoulder into a sawpit the depth of which was eight feet. The writer has witnessed many examples of fracture of the humerus in the line of junction of the superior epiphysis with the shaft of the bone, or in the immediate vicinity of this line. In these cases the youth of the patient, and the situation of the fracture, led him to con- jecture that a separation of the superior epi- physis of the humerus had occurred; but he had no opportunity of ascertaining anatomi- cally the true nature of the l
