Abstract
Deformity of the forearm is common in patients with multiple osteochondromas, producing cosmetic and functional impairment in which shortening of the ulna is a significant factor. The results of ulnar lengthening with excision of the osteochondromas in three forearms of three patients are reported. In all patients, the cosmetic appearance was improved. In one patient without dislocation of the radial head, clinical result was excellent. But in two patients with dislocation of the radial head, they got deterioration of the forearm movement and pain in the wrist joints after surgery. We propose the new method for reduction of the radial head with ulnar lengthening. Deformities of the forearm should be treated before dislocation of the radial head to prevent disability.
