髋关节撞击征的诊断和治疗

Diagnosis and Treatment of The Femoroacetabular Impingement

髋关节撞击综合征(femoroacetabular impingement,FAI)是以髋关节解剖结构异常而引发的股骨近端和髋臼间发生异常碰撞,从而导致髋关节盂唇和关节软骨的退行性变化,引起髋关节慢性疼痛的疾病。髋关节活动范围特别是屈曲和内旋受限,最终发展为髋关节骨关节炎。FAI在我国国内为一个较新的概念,临床能得到诊断的病例不多,但实际病例很多,相当一部分的髋关节疼痛是由撞击征造成,平常的药物止痛不能解除持续的撞击,最终会发生骨关节炎。由此早期的诊断及手术干预,可以消除疼痛,防止骨关节炎的发生,进而推迟或消除关节置换手术是有巨大的经济和社会价值。

Femoroacetabular impingement （FAI） is a condition of too much friction in the hip joint. Basically, femoral head and acetabulum rub abnormally results in the degenerative changes of the hip joint, cause chronic pain of patients. Hip joint range especially buckling and intemal rotation is limited, eventually results in the tearing of the labrum and breakdown of articular cartilage （osteoarthritis）. FAI is a new concept in our country, very few cases can be diagnosed and treated correctly, however, there are so many cases need to be cure. Quite a number of hip chronic pain is caused by FAI. The conventional painkillers can not resolve the fi＇iction of hip joint, finally it leads to osteoarthritis. Therefore, early diagnosis and surgical intervention can eliminate the pain and prevent the occurrence of os- teoarthritis, delay or prevent hip replacement surgery. It has important economic and social effect.
