Reverse second dorsal metacarpal artery flap for reconstruction of fourth-degree burn wounds of the hand

We sought to show how severe soft-tissue injuries of the proximal index finger caused by fourth-degree electrical burns to the hand may be surgically reconstructed. Soft-tissue coverage was provided with a reverse second dorsal metacarpal artery flap in two patients. Both digits were successfully salvaged by use of this reconstructive method. Both donor sites were closed primarily and healed without difficulty. The reverse second dorsal metacarpal artery flap provides well-vascularized tissue without excess bulk and allows near-normal hand function.
