Iliotibial Band Syndrome


What is iliotibial (IT) band syndrome?

Iliotibial (IT) band syndrome can be a cause of pain along the outside of the hip.

The IT band is thick supportive tissue (fascia) that begins at the pelvis, crosses the outer aspect of the hip (greater trochanter) and extends to the tibia (one of the large bones below the knee) on the outer aspect of the knee.

Iliotibial band syndrome is common in athletes, particularly runners. IT band syndrome result in a condition called "external snapping hip", where the IT band snaps over the greater trochanter causing pain or even a popping noise. IT band syndrome can be treated with rest, activity modification, foam rolling and physiotherapy to stretch the IT band.

If conservative measures fail to improve IT band syndrome of external snapping, hip arthroscopy can be undertaken to lengthen the IT band.
