Indomethacin: an adjunct to surgical excision of immature heterotopic bone formation in a patient with a severe head injury. A case report.

This case reports heterotopic ossification which produced ankylosis around the hip joint in a young adult treated with steroids for moderate cognitive defects secondary to brain trauma. It is associated with a high recurrence rate, especially if the bone is immature. The patient's heterotopic bone was surgically excised nine months post-injury, augmented with six weeks of indomethacin, and followed for three years.
