title: Femoroacetabular impingement: a resurfacing solution.
abstract: Femoroacetabular impingement (FAI) is commonly   associated with early hip arthritis. We reviewed our series of 1300   hip resurfacing procedures. More than 90% of our male patients,   with an average age of 53 years, had cam impingement lesions. In   this condition, there are anterior femoral neck osteophytes, and   a retroverted femoral head on a normally anteverted neck. It is   postulated that FAI results in collision of the anterior neck of   the femur against the rim of the acetabulum, causing damage to the   acetabular labrum and articular cartilage, resulting in osteoarthritis.   Early treatment of FAI involves arthroscopic or open removal of   bone from the anterior femoral neck, as well as repair or removal   of labral tears. However, once osteoarthritis has developed, hip   replacement or hip resurfacing is indicated. Hip resurfacing can   re-orient the head and re-shape the neck. This helps to restore   normal biomechanics to the hip, eliminate FAI, and improve range   of motion. Since many younger men with hip arthritis have FAI, and   are also considered the best candidates for hip resurfacing, it   is evident that resurfacing has a role in these patients.
