Reverse dorsometacarpal flap in digits and web-space reconstruction.

Abstract

Skin defects in some areas of the digits are difficult to reconstruct, such as the ulnar aspect of the little or ring finger, radial aspect of the index, dorsal or volar aspect of fingers with proximal interphalangeal or metacarpophalangeal joint involvement, and proximal phalanx of the thumb. Moderate or severe contracture of the web space and multiple finger injuries without an available cross-finger flap are also a challenge to reconstructive surgeons. The reverse dorsometacarpal flap presents an option for reconstruction because of these difficulties. It is reliable and versatile in design. The donor site can be closed primarily provided the flap is less than 2 cm wide.
