Tendofascial island flap based on distal perforators of the radial artery: anatomical and clinical approach.

Abstract

The possibility of transferring vascularized tissue to restore function and to resurface large defects, together with the use of composite flaps, has led to recent advances in "one-stage" reconstructive surgical procedures. On the basis of a previous study of the blood supply of the adipofascial flap and a new study of the blood supply of the flexor carpi radialis tendon from the transfascial and direct branches of the radial artery, a fascial island flap complete with tendon was devised and used to treat four male patients who had sustained traumatic soft-tissue losses on the dorsum of the hand and segmental losses of the extensor digitorum communis. The use of a completely vascularized, single-stage, composite flap did not involve sacrifice of the radial artery, the functional and aesthetic results were good, and there was minimal donor-site morbidity.
