Upper limb reconstruction with reverse flaps: a review of 52 patients with emphasis on flap selection.

Abstract

Reverse flaps lend themselves to transposition from proximal to distal locations in the extremities. This series comprised 18 radial forearm flaps, 17 digital artery flaps, 13 posterior interosseous flaps, 3 lateral arm flaps, 2 dorsal digital flaps, and 1 dorsal metacarpal flap, all of which were utilized in a reverse pattern. The radial forearm flap was mainly chosen for defects involving part of the palm and the palmar aspect of the first web space. The posterior interosseous flap was more commonly utilized for resurfacing the dorsum, dorsal aspect of the first web space, and especially the hypothenar aspect of the hand. The lateral arm flap was used to reconstruct antecubital fossa and proximal forearm defects. All posterior interosseous and lateral arm donor areas were closed primarily. Sensate digital artery flaps yielded 5 mm on average static two-point discrimination in 6 to 18 months of follow-up. Functional and cosmetic results concerning the recipient and donor areas were found to be satisfactory. It was concluded that reverse flaps are versatile tools in the coverage of all kind of defects in the upper limb and should be thought of in the first place.
