The Use of Tensor Fascia Lata Interposition Grafts for the Treatment of Posttraumatic Radioulnar Synostosis

PurposeThere 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.MethodsA 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.ResultsThirteen patients were identified for this study. The mean preoperative pronation was 14° and the mean postoperative pronation was 62°. The mean preoperative supination was 4° and the mean postoperative supination was 62°. The mean follow-up time was 30 months.ConclusionsThese results indicate that synostosis resection with tensor fascia lata graft interposition is an effective technique for the treatment of posttraumatic radioulnar synostosis.Type of study/level of evidenceTherapeutic, Level IV.
