Homodigital Antegrade-Flow Neurovascular Pedicle Flaps for Sensate Reconstruction of Fingertip Amputation Injuries

Abstract

Fingertip amputations through the distal 50% of the nail matrix usually create a finger that is best served by maintaining length. When the amputation is more proximal than this, revision with ablation of the small residual nail unit may provide greater overall patient satisfaction. When amputations in the distal 50% of the nail matrix are transverse or short oblique in orientation, a flap of some kind is needed to restore the contact surface of the pulp. Many alternative reconstructive strategies are possible but have inherent limitations that detract from the quality of the final result. Inadequate padding, lack of sensibility, excessive tension, hook nail deformity, poor durability, and donor site morbidity are but some of the considerations. Although not a panacea for all distal fingertip amputations, the antegrade-flow homodigital neurovascular pedicle flap offers a good ratio of advantages to disadvantages. As with all flaps, knowledge and execution of the details largely determine the outcome.
