A major avulsion is easy to overlook when an elbow has been transiently dislocated and then reduces spontaneously5,6 because the detached epicondyle may, on the AP radiograph, be mistaken for the normally positioned trochlear ossification centre (p. 105). Displacement of the anterior fat pad alone however can occur due to minimal joint effusion and is less specific for fracture. var windowOpen; 2.
