 eMedicine - Snapping Hip Syndrome : Article by Joseph P Garry
Originating along the posterior ilium, dorsal surface of the sacrum, and gluteal aponeurosis, the gluteus maximus inserts on the iliotibial tract and gluteal tuberosity of the femur.
Subluxation of the iliotibial band over the greater trochanter may occur while the hip extends from a flexed position (in which the iliotibial band lies anterior to the greater trochanter) to a position posterior to the greater trochanter.
Snapping hip syndrome may be due to an external cause (eg, snapping of the iliotibial band or gluteus maximus over the greater trochanter) or an internal cause (eg, snapping of the iliopsoas tendon over the iliopectineal eminence, acetabular labral tear, intra-articular loose body).
