Fracture of the radial forearm osteocutaneous donor site.

Since the introduction of the osteocutaneous radial forearm flap in 1983, fractures of the radius have been reported to occur in approximately 30% of cases. Fracture of the donor forearm has been the cause of the most significant morbidity, and the difficulty in management of these fractures has been reported. We report our experience in managing three fractures involving the donor forearm. Optimum results can be achieved by early stabilization with external fixation and vascularized bone grafting. Excessive resection of the radius should be avoided and alternative sources of vascularized bone used to avoid mutilation of the forearm.
