Figure 3. Anterolateral thigh flap (ALT) design. The ALT is based on the lateral femoral circumflex system^[48]. The dimensions of this flap are determined by the available perforators. Generally, it should be approximately 20 cm in width for a tube-in-a-tube design and can vary in length. The flap should be as distal as possible to ensure pedicle length. Given the dimensions of this flap, the donor site must be skin grafted. Photos courtesy of Dr. Jens Berli
