Reversed neurofasciocutaneous flaps based on the superficial branches of the radial nerve.

Abstract

Soft-tissue reconstruction of the hand needs to cover the vital structures with flaps. It is usually difficult to maintain function and form with minimal morbidity. Local tissue is preferable but it is also very valuable. Especially in the distal part of the upper extremity, flap coverage is a challenging problem because of limited reconstructive alternatives. On the dorsum of the hand, flaps can be designed based on the paraneural vascular network of the cutaneous sensory nerves. These paraneural vascular networks send branches to the surrounding tissues. The branches to the skin are known as neurocutaneous perforators. The authors used eight reversed neurofasciocutaneous flaps based on the superficial branches of the radial nerve. Six flaps were based on the branch to the index finger and two flaps were based on the branch to the thumb. All flaps survived completely, and successful flap coverage was achieved in all patients with minimal morbidity.
