Bifid iliopsoas tendon as a cause for internal snapping hip syndrome: A case report.

Snapping hip syndrome, or coxa saltans, can result in significant clinical manifestations in patients including pain and limited mobility. A variety of both intra- and extra-articular pathologies have been implicated in snapping hip, including an anatomic variant known as the bifid iliopsoas tendon which has been briefly described in the literature. We report a case of a bifid iliopsoas tendon leading to internal snapping hip syndrome which was ultimately successfully treated with surgical release, including review of the clinical presentation, pathophysiology, and dynamic sonographic findings.
