Ulnar Rotation Osteotomy for Congenital XXXX .

@entity1 @entity571 @entity8244 @entity11535 @entity717
PURPOSE: To evaluate an @entity717 for @entity8244 . METHODS: Nine @entity1 (5 @entity1 and 4 @entity1 aged 6 to 13 years) with @entity8244 were treated with @entity717 . Magnetic resonance imaging of the elbow showed the proximal radioulnar joint on the anterior-lateral side of the ulna rather than on the lateral side in @entity1 with @entity8244 . On the basis of this finding, we performed an osteotomy on the ulna and laterally rotated the proximal radioulnar joint achieving radial head reduction and restoring the anatomical relationship between the radial head and the capitellum. Clinical and radiographical evaluation of the elbow was performed before surgery and at postoperative follow-up. RESULTS: All @entity1 were followed for 13 to 45 months after surgery. Elbow radiography showed that the radiocapitellar joint was reduced in all @entity1 at the last follow-up visit and that the carrying angle was decreased relative to that in the preoperative condition. Elbow stability and the range of @entity11535 were improved at the last follow-up. We did not observe ulnar osteotomy site nonunion or @entity571 in these @entity1 . Furthermore, @entity8244 did not recur. CONCLUSIONS: At early follow-up, @entity717 was a safe and effective method for the treatment of @entity8244 . TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
