Functional reconstruction of traumatic loss of flexors in forearm with gastrocnemius myocutaneous flap transfer.

Abstract

Reconstruction of flexor function of forearm remains a challenge in the reconstructive surgery. With development of microsurgical techniques, reconstructive surgeons have been able to envision muscle transplantation for restoration of function and not simply for provision of soft tissue coverage. In this report, we present our experience in three patients of successful treatment of traumatic flexor loss in the forearm with the microsurgical medial gastrocnemius myocutaneous flap. At 18- to 24-months follow-up, the detected action potential (Latency and Amplity) in the transferred muscle was significantly improved in the EMG examination. The strength of the digital flexion reached to III degree in one case, IV degree in two cases. No complications were noted in the donor legs. We conclude that the microsurgical medial gastrocnemius myocutaneous flap transfer can be an ideal alternative for functional reconstruction of the forearm flexor muscle in three posttrauma patients.
