The posterior arm free flap

A new cutaneous free flap is described on the posterior side of the arm. This flap is supplied by an unnamed artery from the humeral artery or the deep humeral artery. It is drained by the accompanying venae comitantes. Its nerve supply is from the radial nerve. Its advantage is a flexible skin and a primary closure of the donor site if the flap does not exceed 7 cm in width. The principal disadvantage is its modest measurements. This flap has been employed in five cases for reconstruction of hand and foot. All flaps survived despite a necessary revision of an arterial anastomosis in one case and a partial necrosis in another case. Results are satisfactory, especially in restoration of weight-bearing areas of the foot.
