title: Posttraumatic radioulnar synostosis treated with a free vascularized fat transplant and dynamic splint: a report of two cases.
abstract: Two cases of posttraumatic radioulnar synostosis are presented. The patients were treated with excision of the cross-union and interposition of a free vascularized fat transplant. A newly devised pronation-supination dynamic splint was employed for 3 months postoperatively in both patients. After a 1-year postoperative follow-up, an increased range of motion was restored in both cases, and there was no evidence of recurrent synostosis formation in subsequent radiographs. We suggest that an interposed vascularized fat graft may be an ideal biologic barrier to fill the space created by cross-union excision.
