A 14-year-old boy experienced a significant injury to his triceps muscle playing football six months prior to when this film was taken. The radiograph shows heavy, mature bone formation in the long head of the triceps muscle fusing the humerus firmly to the scapula so that the boy had severe limitation of motion at the shoulder. This picture is quite diagnostic of traumatic myositis ossificans. Because of the severe restricted motion, he was taken to the operating room and the ossifying mass was resected. Following surgery, he was placed on Didronel to reduce the chance of further heterotopic bone formation.
