Ultrathin Free Flaps to the Foot and Ankle: New Options for Optimal Soft Tissue Coverage and Functional Contour

Soft tissue defects and chronic wounds around the foot and ankle can prove difficult to reconstruct using conventional techniques. Traditional flaps used for coverage in this region can result in the need for future debulking, shoe gear modifications, donor site morbidity, decreased function, and scarring. Successful reports of ultrathin free flaps harvested along suprafascial planes have yet to be described in the foot and ankle literature. We present 2 cases of ultrathin flaps used for foot and ankle defects that provide optimal contour while not limiting anatomic function. The resultant functional outcomes and contour shown by both flaps underscore the benefit of a thin and pliable flap in this region.
