Abstract

The snapping hip syndrome is a symptom complex characterized by hip pain and an audible snapping of the hip with exercise typically seen in young individuals. External and internal etiologies have been described, although the internal etiology is poorly understood. A clinical, radiographic, and anatomical study of eight patients with this disorder secondary to an internal etiology, was undertaken to aid in the diagnosis and surgical treatment. Iliopsoas bursography with cineradiography revealed subluxation of the ilopsoas tendon to be an apparent cause of the snapping hip. The anatomy of the hip in relationship to the iliopsoas tendon is defined with the anterior inferior iliac spine, iliopectineal eminence, and lesser trochanter assuming a significant role in the syndrome. An operative approach involving a partial release and lengthening of the iliopsoas tendon, with minimal resection of a lesser trochanteric bony ridge, if involved, is described. Verf.-Referat
