Snapping iliopsoas tendon in a recreational athlete: a case report.

OBJECTIVE

To describe the evaluation, diagnosis, and conservative treatment of a 31-year-old female recreational athlete with a snapping iliopsoas tendon.

BACKGROUND

The iliopsoas tendon has been implicated as an inflamed structure in this unique form of snapping hip. Hip pain, limitation of motion, or both may severely restrict vocational and recreational function and activities of daily living.

DIFFERENTIAL DIAGNOSIS

Left snapping hip syndrome secondary to the iliopsoas tendon or the iliotibial band.

TREATMENT

The treatment goal was to restore the athlete's pain-free, functional abilities. The primary focus of the treatment program was stretching of the left hip flexors. The patient demonstrated reduced pain and improved function following a 4-week stretching program and was fully functional and symptom free at 6 months.

UNIQUENESS

Snapping hip syndrome is a clinical entity that may be described as hip pain associated with an audible snap of the hip during motion. The most common and well-known cause of this syndrome involves the snapping of the iliotibial band over the greater trochanter. A less common cause is the snapping of the iliopsoas tendon over the iliopectineal eminence.

CONCLUSIONS

Understanding the anatomy and function of the iliopsoas tendon and related structures provides a basis for evaluation and treatment of this unique problem.
