It serves as an accessory muscle in abduction and flexion of the hip. Tensor fascia latae is one of two muscles that insert onto the iliotibial band. The tensor fasciae latae is a tiny muscle, inferior to the iliotibial band.


Where does the tensor fascia latae muscle attach? Tensor fascia latae inserts on the iliotibial band. Together with gluteus maximus and the iliotibial band, it further stabilizes the hip joint by holding the head of the femur in the acetabulum. Tensor fasciae latae muscle is the prime mover in hip medial rotation and a weak hip abductor motion.

Origin. The tensor fasciae latae originates just behind (posterior) or to the outside of the Anterior Superior Iliac Spine or ASIS. Insertion.
TENSOR FASCIA LATA. ORIGIN Outer surface of anterior iliac crest between tubercle of the iliac crest and anterior superior iliac spine: INSERTION Iliotibial tract (anterior surface of lateral condyle of tibia) ACTION Maintains knee extended (assists gluteus maximus) and abducts hip:
