A young boy who has been a star pitcher for his Little League team suddenly complains of swelling and extreme soreness of his pitching arm at the elbow whenever he throws a pitch. How would a knowledge of surface anatomy assist in determining the nature of the problem?
What will be an ideal response?
An examination of the sore region would indicate that most of the pain occurs with rapid extension of the arm, as occurs during the final phase of a pitch. The point of the elbow and the area distal to it are also sore and swollen. The probable cause of this problem is a separation of the epiphysis of the ulna from the diaphysis, which separates the olecranon process from the shaft of the bone, causing irritation and swelling.
