1) capitellum; 2) radial head; 3) internal (medial) epicondyle; 4) trochlea; 5) olecranon; and 6) external (lateral) epicondyle. The medial epicondyle is an apophysis since it does not contribute to the longitudinal growth of the humerus. Try to find out what went wrong in the chapter on positioning. 1. When checking the position of the internal epicondyle on the AP radiograph: If part of the epicondyle is covered by part of the humeral metaphysis then an avulsion has not occurred.
