The Second Dorsal Metacarpal Artery Neurovascular Island Flap

Abstract

Eleven patients have had second dorsal metacarpal sensate island flaps used to cover local skin defects in the hand. The arterial supply is reliable but if the flap is extended beyond the proximal interphalangeal joint, distal flap necrosis or donor site difficulties may occur. Possible applications for this flap are demonstrated and some untried variations to increase its range are suggested. Its main use appears to be in the release of first web contractures and for resurfacing radio-palmar and thumb defects.
