Anterolateral Thigh Flap
- 406 Downloads
The anterolateral thigh (ALT) compartment has four anatomical limits: the rectus femoral muscle medially, the iliotibial tract laterally, the anterior superior iliac spine (ASIS) inferiorly, and the lateral femoral condyle inferiorly. A superficial fascia, with subcutaneous tissue, covers the entire muscular structure. The deepest fascia in the lateral part is formed by the tensor muscle of the fascia lata connected with the fascia lata to compose the iliotibial band, which provides stability in the knee joint.
