髂前下棘与棘下撞击综合征

Anterior inferior iliac spine and subspine impingement syndrome

髋股撞击综合征是髋关节骨关节炎重要的诱发因素之一,而关节外撞击诱发的髋股撞击综合征往往不为人所重视。髂前下棘下间隙正常情况在髋关节屈曲时提供缓冲区域。髂前下棘异常增生时会造成髋臼盂唇损伤、髋股撞击综合征和软骨损伤。目前涉及髂前下棘撞击症的文献较少,本文的重点在于对目前髂前下棘撞击征的发病原因、临床诊断以及治疗方法进行归纳分析,为临床医师认识和治疗髂前下棘撞击症提供理论依据。

The femoro-acetabular impingement syndrome （FAI） is one of the risk factors of hip osteoarthritis. However, the FAI due to extra-articular factors is always neglected in clinical practice. The normal subspine space provides a buffer area for the hip labrum during flexion. Abnormal hypertrophy of anterior inferior iliac spine （AIIS） causes labrum lesion, impingement and cartilage injury. To date, few studies have been focusing on the etiology of subspine impingement. The objective of this article was to summarize the causes, the diagnosis as well as the managements of the subspine impingement. The review would provide evidences to the clinical treatment of subspine impingement.
