[citation needed] The more common lateral extra-articular type of snapping hip syndrome occurs when the iliotibial band, tensor fasciae latae, or gluteus medius tendon slides back and forth across the greater trochanter.

This normal action becomes a snapping hip syndrome when one of these connective tissue bands thickens and catches with motion.

[citation needed] Less commonly, the iliopsoas tendon catches on the anterior inferior iliac spine, the lesser trochanter, or the iliopectineal ridge during hip extension, as the tendon moves from an anterior lateral (front, side) to a posterior medial (back, middle) position.

[2] Athletes appear to have an increased risk of snapping hip syndrome due to repetitive and physically demanding movements.

[citation needed] Extra-articular snapping hip syndrome is commonly associated with leg length difference (usually the long side is symptomatic), tightness in the iliotibial band (ITB) on the involved side, weakness in hip abductors and external rotators, poor lumbopelvic stability and abnormal foot mechanics (overpronation).

[7] The causes of intra-articular snapping hip syndrome seem to be broadly similar to those of the extra-articular type, but often include an underlying mechanical problem in the lower extremity.

[citation needed] Referral to an appropriate professional for an accurate diagnosis is necessary if self treatment is not successful or the injury is interfering with normal activities.

The examiner may check muscle-tendon length and strength, perform joint mobility testing, and palpate the affected hip over the greater trochanter for lateral symptoms during an activity such as walking.

In addition, corticosteroid side effects can include weight gain, weakening of the surrounding tissues, and even osteoporosis, with regular use.

[citation needed] If medicine or physical therapy is ineffective or abnormal structures are found, surgery may be recommended.

[citation needed] Both active and passive stretching exercises that include hip and knee extension should be the focus of the program.

Light aerobic activity (warmup) followed by stretching and strengthening of the proper hamstring, hip flexors, and iliotibial band length is important for reducing recurrences.
