Thin and Thinned Anterolateral Thigh Flaps for Upper Extremity Reconstruction

Abstract

Upper extremity reconstruction remains challenging due to the high functional and esthetic demands of this location. The anterolateral thigh (ALT) flap is a workhorse flap for microsurgical reconstruction of the upper extremity and can be elevated in various planes depending on desired thickness of the flap. Microsurgical reconstruction of the upper extremity often benefits from a thin flap that can resurface the extremity, which can provide improved functional and esthetic outcomes. This article reviews the anatomy, preoperative planning, and operative technique, as well as presents 4 cases to illustrate the outcomes and benefits of thin and thinned ALT flaps.
