Extremity reconstruction using the free deltoid flap

The deltoid fasciocutaneous flap is a thin, reliable flap that is easily dissected from the posterolateral arm. It has large-caliber vessels and is capable of sensory reinnervation to portions of the flap above the deltoid/triceps groove through the lateral brachial cutaneous nerve. There is little sensory return to the large vascular territory, which can be extended inferiorly below the deltoid triceps groove. The donor site can be closed primarily or skin grafted and when large may be objectionable to some patients. The flap is an excellent choice for extremity soft-tissue reconstruction on the plantar or palmar surfaces. Protective sensibility has returned to all reinnervated flaps. We present our experience in 10 patients with extremity problems.
