The segmental rectus abdominis free flap for ankle and foot reconstruction

The reconstruction of soft-tissue defects of the ankle and foot usually requires free-tissue transfer. Although certain local flaps have been described for the reconstruction of these injuries, their utility may be compromised by significant crush injury or the size and location of the defect. Part of the rectus abdominis muscle, the segmental rectus abdominis free flap, is ideally suited for this use because of the muscle's versatility, reliability, and negligible donor deformity when harvested through a low transverse abdominal incision. Seven patients reconstructed with this flap are presented, and the technique is discussed. All patients have been successfully reconstructed with preservation of the ankle and foot. At present, all patients are fully or partially weight-bearing. The segmental rectus abdominis free flap is recommended for the reconstruction of such wounds.
