title: Low back pain associated with internal snapping hip syndrome in a competitive cyclist.
abstract: Low back pain is a common complaint among cyclists. Here we present the case of a competitive master cyclist with low back pain and whose symptoms ultimately resolved when he was treated for internal snapping hip syndrome. Internal snapping hip syndrome is a painful lesion of the iliopsoas caused by snapping of the tendon over the iliopectineal eminence or anterior femoral head when the femur is extended from a flexed position. This is the first published report that we are aware of that describes this syndrome as a potential cause of low back pain in a competitive cyclist.
