title: One-stage rotational osteotomy for congenital radioulnar synostosis.
abstract: We report the results of a one-stage rotational osteotomy of the proximal third of the ulna and distal third of the radius with segmental bone resection for treating congenital radioulnar synostosis. We retrospectively reviewed 25 patients (28 forearms) treated by operation. Patients were divided into two groups according to the method of internal fixation at the osteotomy sites. In Group 1 the ulnar osteotomy was stabilized with an intramedullary pin and in Group 2 no fixation was used. The average forearm position improved from 47° pronation before surgery, to 27° supination after surgery. There were no statistically significant differences between the two groups in surgical outcomes. One-stage rotational osteotomy of the proximal third of the ulna and distal third of the radius with segmental bone resection is a simple and safe treatment for patients with congenital radioulnar synostosis. Internal fixation at the osteotomy site seems to be unnecessary. Level of evidence: Level 4.
