Anterolateral thigh flap technique in hand and upper extremity reconstruction

The anterolateral thigh flap is an extremely versatile flap first described in 1984. The flap is based on either a septocutaneous or musculocutaneous perforator of the descending branch of the lateral circumflex femoral system. It can be designed as a skin and subcutaneous flap, fasciocutaneous, or musculocutaneous flap. Furthermore, it can be harvested as a sensate flap by taking the lateral cutaneous nerve of the thigh. Technique for harvesting the flap is described in detail. Complications include flap failure and donor site morbidity. Due to its versatility, the anterolateral thigh flap is particularly useful for upper extremity reconstruction.
