More than 17% of men and 4% of women suffer from hip and groin pain due to a bump at the femoral head causing impingement between the ball and hip socket for activities requiring large hip flexion and external rotation. This condition is named cam femoroacetabular impingement (FAI). Symptoms are related to the degree of deformities and occur earlier in the presence of activities requiring high range of motion of the hip joint. Increasing evidence suggests that hip bone deformity contributes to the development of early adult hip osteoarthritis (OA). Although the causes of cam FAI remains unknown, the alteration of bone remodelling due to high mechanical stresses between the head-neck junction of the femoral head and the hip socket's rim could be one of the risk factors.

超过17%的男性和4%的女性患有髋关节和腹股沟疼痛，这是由于股骨头处的肿块导致需要大髋关节屈曲和外旋的活动中球和髋关节窝之间的撞击。这种情况被称为凸轮股骨髋臼撞击（FAI）。症状与畸形的程度有关，并且在需要髋关节大范围活动的活动中出现较早。越来越多的证据表明，髋骨畸形有助于早期成人髋关节骨关节炎（OA）的发展。虽然凸轮FAI的原因尚不清楚，骨改建的改变，由于高机械应力之间的股骨头和髋关节窝的边缘的头颈交界处可能是一个危险因素。
