Extended Trapezius Myocutaneous Free Flap for the Reconstruction of a Foot Defect Lacking Adjacent Recipient Vessels

Abstract

Foot reconstruction requires tissue that is durable and can withstand the extremes of pressure and stress. The trapezius myocutaneous flap has not been used previously as a free flap for foot reconstruction. In this report, the trapezius was used as an extended myocutaneous free flap for the reconstruction of a foot wound lacking adjacent and adequate recipient vessels. The extended trapezius flap may be one of the longest free flaps that can be harvested. The indications for the use of this flap are limited. In an extremity that lacks adequate recipient vessels adjacent to the defect, this flap can be extended such that more proximal vessels in the leg can be used as the recipient vessels without the need for vein grafts to bridge the distance. The donor-site morbidity of this flap is minimal when the superior fibers of the trapezius muscle and its innervation are preserved.
