Humeroulnar Bridging Myositis Ossificans Traumatica: A Case Report

Myositis ossificans traumatica (MOT) of the elbow is a rare entity in children. It is a self-localized tumor-like lesion of the elbow causing ankylosis due to humeroulnar bridging. It is a complication arising due to a muscle contusion injury.

We report a case of an 8-year-old female who presented with a 2-year history of a fixed elbow and a palpable bony mass. The examination confirmed a confined bony mass on the anterior aspect and ankylosis of her left elbow. On confirmation of the diagnosis, an en bloc excision was performed. Follow-up every 2 weeks for the first 3 months, then once a month for the next 6 months, and finally once every 6 months for the next 4 years. The affected limb functioned well, with no sign of recurrence.

MOTs of the elbow in children are a rarity, and excision of the lesion without delay is an effective management strategy for a satisfactory outcome.
