Unusually Large Myositis Ossificans of Elbow

Abstract

An eighteen year old male came to our out-patient department with contusion right elbow with moderate edema and tenderness. X-rays showed no evidence of fracture. He was treated with above elbow POP slab in 90 degree flexion. He was lost for follow up and presented 6 weeks later with a swelling in the anterior aspect of arm and inability to flex the elbow to full range. He had massage after removing the plaster. On examination flexion was possible only upto 45 degree and a bony hard, non tender, large non mobile mass was palpated over anterior aspect of ann. Roentgenographic examination showed an anterior myositis ossificans of $6\times4$ ems in brachialis. He was treated conservatively with indomethacin, isometric muscle strengthening and gentle active assisted range of muscle exercises within the limits of pain. Range of motion progressively increased over a period of 2 months, and he could improve his range to 110 degree. By another 2 months he was able to completely restore the mobility, the size of the myositis mass decreased.
