Femoroacetabular impingement is a newly defined painful hip pathology that affects young adults. The pain is due to mechanical impingement between the femoral head-neck junction and the acetabular rim during hip movement, especially in flexion. This abnormal and recurring impingement results in destruction of the labrum and cartilage, which is thought to result in osteoarthritis of the hip in untreated patiens. In the current literature, it seems that early surgical treatment of this mechanical problem stops or delays the advancement of this hip disease.
