The use of tensor fascia lata interposition grafts for the treatment of posttraumatic radioulnar synostosis.

Abstract

There is no agreement on the ideal treatment of traumatic radioulnar synostosis, especially the type of interposition material to be used. The purpose of this study is to report our experience with synostosis resection and interposition of tensor fascia lata grafts. A chart review was conducted for all patients treated for posttraumatic radioulnar synostosis between 2000 and 2004. Demographic data, mechanism of injury, length of time to synostosis resection, range-of-motion, patient satisfaction, and postoperative complications were analyzed. Thirteen patients were identified for this study. The mean preoperative pronation was 14 degrees and the mean postoperative pronation was 62 degrees. The mean preoperative supination was 4 degrees and the mean postoperative supination was 62 degrees. The mean follow-up time was 30 months. These results indicate that synostosis resection with tensor fascia lata graft interposition is an effective technique for the treatment of posttraumatic radioulnar synostosis. Therapeutic, Level IV.
