Double keystone flap for large lower thigh defect

Abstract

Large lower thigh defects are a reconstructive challenge. Keystone design perforator island flap in the lower thigh is not routinely performed as the skin here is less extensible. We present a case of a large anterolateral lower thigh defect wherein we used double keystone flaps from the remaining circumference of the thigh and grafted the donor site in the posterior thigh. Circumferential incision/scarring in the limbs risk damage of superficial lymphatico-venous circulation and distal edema. However, our case demonstrates an uneventful recovery and excellent aesthetic and functional outcome.
