Use of reverse second dorsal metacarpal artery flap for the treatment of syndactyly of the first web

Abstract

Complex Syndactyly in the hand it is a challenge for surgical corrections. A critical point to assess is the reconstruction of the web space, while scarcity of skin it is often present. The web space should be always planned and designed to bring some function and covering of the deformities. The first web space has an importance to give function on grasping and pinch. In this report, we present a case of a complex syndactyly with a narrow first web space that was reconstructed by the second dorsal metacarpal artery flap. Despite of a critical malformation in the hand, the patient improved his pinch function and showed a good aesthetic outcome. We believe that this flap could be considered an alternative in dealing with this kind of condition and bring a satisfactory solution for web space reconstruction.

Hand soft tissue reconstruction with dorsal metacarpal artery perforator (Quaba) flap

“…The dorsal metacarpal artery, a thin fasciocutaneous local flap, is one of the most effective reconstructive methods for soft-tissue defects of the metacarpophalangeal joint, web space, proximal phalanx, and proximal interphalangeal joint perforator (Quaba) flap, with reliable and relatively straightforward anatomy of the pedicle [ 2 ]. While most commonly used for dorsum soft tissue defects of the proximal phalanx, it can also have good results when used for the volar side of the proximal phalanx [ 3 ].…”
