title: Femoroacetabular impingement--diagnosis and treatment.
abstract: Femoroacetabular impingement results from an abnormal contact between the femur and the pelvis. This abnormal contact leads to developmental changes in the femoral neck, labrum, and acetabulum. Secondary to the altered hip joint mechanics, chondral damage occurs and initiates the degenerative process, eventually leading to osteoarthritis. Numerous etiologies have been implicated in femoroacetabular impingement, and a variety of treatment algorithms have been established, with no definitive gold standard. However, the treatment of this disorder with joint preserving techniques offers a viable option between the extremes of nonoperative treatment and total joint arthroplasty.
