The dorsal reverse adipofascial flap for fingertip reconstruction.

Nine patients who presented with fingertip amputations were treated with the dorsal reverse adipofascial flap. The mean age of the patients was 41.3 years and the mean follow-up was 18 months. The flap described here was used only for amputations at the level of the nail fold, from approximately the lunula to the proximal nail matrix. This flap is based on the dorsal arterial branches that originate from the volar digital arteries just distal to the distal interphalangeal joint. The flap uses only the adipofascial tissue over the middle phalanx of the injured finger; it is turned over to cover the fingertip defect and then covered with a split-thickness skin graft. All flaps survived completely, and the patients continue to use their fingertips as before the amputation injury. This one-step operation is easily performed (even in the emergency department), makes no use of the adjacent digits, and provides a pleasing and stable cover for the fingertips.
