The reverse radial artery flap or chinese flap is still the gold standard for reconstruction of skin loss of the hand. The major disadvantage of the flap is the division of the radial artery. With the understanding of microcirculation of small perforators originated from the main vessel at the wrist region, we have been able to harvest this flap without sacrificing the radial artery. We performed consecutively 11 cases in two years with satisfactory results for skin coverage of both dorsal and volar aspects of the hand. There was one partial necrosis of the distal portion of the flap, treated with a free lateral arm flap, with anastomosis at the radial artery, which was preserved. We think it is a reliable and versatile flap, being an option of the traditional chinese flap or the posterior interosseous artery flap, in hand reconstructive surgery.
