Treatment of forearm deformity with radial head dislocation because of multiple osteochondromas: a series of three cases treated by simple axis correction and distraction osteogenesis of the ulna.

Radial head dislocation in multiple osteochondroma leads to functional impairment and cosmetic problems, and surgical intervention has not been successful to date, with high rates of redislocation. Simple correction of the longitudinal axis and distraction oste8ogenesis of the ulna without corrective osteotomy of the radius were performed within 1 year of radial head dislocation. The mean age of the patients was 7.2 years and the postoperative follow-up duration was 63.6 months. In all cases, the dislocated radial head was repositioned without surgical invention involving the radius. All patients were pain free, with no impairment of daily activity, and all were satisfied with the cosmetic appearance, indicating successful medium-term postoperative outcomes for our surgical procedure.
