title: Fracture of a supracondylar humeral myositis ossificans.
abstract: Although myositis ossificans is a well-known sequela of elbow trauma, reinjury to the affected region can also occur, resulting in acute symptoms from a fracture of the myositis ossificans. An 18-year-old man presented with localized pain, soft-tissue swelling, and a bony mass along the anterolateral distal humerus with restricted elbow range of motion after injury to his elbow during football. One year earlier he had sustained a similar crush injury to his elbow that resulted in a limited, although painless, arc of motion. Radiographs and tomograms established the diagnosis of a fractured supracondylar humeral myositis ossificans. Surgical excision of the large mature ossified fragment confirmed the diagnosis and restored a full range of motion of the elbow.
