A Thickening of fascia lataRef: Grays Anatomy, 41st ed. pg. 1337-38 The iliotibial tract is a thickened portion of the deep fascia of the thigh fascia lata. This tract runs from the lateral aspect of the iliac crest to Gerdys tubercle and produces the flattened appearance of the lateral thigh. The attachment on Gerdys tubercle is on the anterior aspect of the lateral condyle that is usually approximately 1 cm inferior to the joint line and about 2 cm superolateral to the tibial tuberosity. The upper end of the tract splits into two layers, where it encloses and anchors tensor fasciae latae and receives, posteriorly, most of the tendon of gluteus maximus.
