IT Band Syndrome

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, running or hiking).

It is usually developed by people who suddenly increase their level of activity, such as runners who increase their mileage. Other risk factor for ITBS include gait abnormalities, for example overpronation, leg length discrepancies, or bow-leggedness.

The Iliotibial Tract or Iliotibial Band (a.k.a. Maissiat's band, IT Band) is a longitudinal fibrous reinforcement of the fascia lata. It is attached to the midpoint of the external lip of the iliac crest and to the lateral condyle of the tibia. The figure shows only the proximal part of the iliotibial tract.
