Reverse digital artery neurovascular cross-finger flap.

Abstract

Soft tissue loss with digital nerve defect in the finger was reconstructed with the reverse digital artery neurovascular cross-finger flap in two cases with favorable results. The flap harvested from the lateral side of the proximal phalanx of the neighboring healthy finger is nourished by a distally based digital artery. The flap contained a segment of digital nerve dorsal branch, which is used to bridge the nerve gap in the wound while the flap is used to reconstruct the soft tissue defect concomitantly. The reverse digital artery neurovascular cross-finger flap seems to be a useful addition to the options for complicated finger damage involving soft tissue loss and nerve defect.
