Iliotibial tract

The iliotibial tract (iliotibial band) is a superficial band of fascia covering the thigh. It is a downward continuation of the Fascia lata.

It is attached to the lateral condyle of the tibia.

The part of the iliotibial band which lies beneath the Tensor fasciæ latæ is prolonged upward to join the lateral part of the capsule of the hip-joint.

The Gluteus maximus muscle inserts upon the tract.

Clinical significance
Iliotibial Band Syndrome (ITBS or ITBFS, for Iliotibial Band Friction Syndrome) is a common thigh injury generally associated with running. Additionally it can also be caused by biking, hiking or weight-lifting (especially squats).
