Origin: Iliac crest
Insertion: Iliotibial tract
Artery: Primarily lateral circumflex femoral artery, Superior gluteal artery
Nerve: Superior gluteal nerve (L4, L5)
Action: Thigh - flexion, medial rotation. Trunk stabilization.
The Tensor fasciae latae (Tensor fasciae femoris) arises from the anterior part of the outer lip of the iliac crest; from the outer surface of the anterior superior iliac spine, and part of the outer border of the notch below it, between the Glutaeus medius and Sartorius; and from the deep surface of the fascia lata. It is inserted between the two layers of the iliotibial band of the fascia lata about the junction of the middle and upper thirds of the thigh.
