This study evaluates donor site outcomes in patients receiving radial forearm free flap reconstruction versus ulnar forearm free flap reconstruction. Patients who meet criteria for forearm free flap reconstruction are randomized to receiving either radial forearm free flap or ulnar forearm free flap reconstruction.
The radial forearm free flap and the ulnar forearm free flap are both well-described procedures used for free tissue transfer in reconstructive surgery. Although forearm free flaps are frequently performed, there is insufficient prospective data looking at the morbidity of the radial compared to ulnar forearm free flaps. The goal of this research study is to characterize the outcomes for each of these two flaps, and to determine if there is surgical equipoise, or if one flap is better than the other.
