Innervated Gluteus Maximus For Huge Thigh & Groin Defects

Abstract

Gluteus maximus is a bulky muscle with three sources of blood supplying also a skin flap that extends from iliac crest down to the popliteal fossa. The myocutaneous flap has been used long time ago, as an insensate flap, to cover defects in the buttocks.9,10,12 In this study we use this muscle as a sensate flap keeping sensory and motor nerves, to cover major defects in the buttocks and groin. This study included seven cases with different indications. The technique depends upon full mobilization of the muscle based on two main vascular pedicles to maintain adequate vascularity and nerve supply of the transposed flap.
