The tensor fasciae latae (TFL) is a muscle of the proximal anterolateral thigh that lies between the superficial and deep fibers of the iliotibial (IT) band. There is high variability in muscle belly length, although, in most patients, the TFL muscle belly ends before the greater trochanter of the femur. The TFL works in conjunction with the gluteus maximus, gluteus medius, and gluteus minimus in various hip movements, including flexion, abduction, and internal rotation. This muscle acts via the iliotibial (IT) band's attachment to the tibia to assist with knee flexion and lateral rotation. The TFL is most important clinically for assisting pelvic stability while standing and walking.
阔筋膜张肌（TFL）是大腿近端前外侧的一块肌肉，位于髂胫束（IT）的浅纤维和深纤维之间。肌腹长度存在很大差异，不过，在大多数患者中，阔筋膜张肌的肌腹在股骨大转子之前结束。阔筋膜张肌在各种髋关节运动中，包括屈曲、外展和内旋，与臀大肌、臀中肌和臀小肌协同工作。该肌肉通过髂胫束附着于胫骨来发挥作用，以协助膝关节屈曲和外侧旋转。阔筋膜张肌在临床上最重要的作用是在站立和行走时协助骨盆稳定。
