髋臼盂唇与发育性髋关节发育不良

The acetabular labrum and developmental dysplasia of the hip

髋臼盂唇是由骨性髋臼外缘延伸而出的坚韧的纤维软骨结构,在维持髋关节稳定、压力平衡及生长发育等方面起着重要作用。在发育性髋关节发育不良(developmental dysplasia of the hip,DDH)中,股骨头脱位、半脱位后对髋臼产生的异常应力使盂唇肥厚、退变,阻碍股骨头中心复位。但在DDH治疗中对髋臼盂唇的处理尚存争议,该文综述了正常盂唇与DDH盂唇的解剖、影像学特点及其对DDH治疗的影响。

The acetabular labrum,a tough fibrocartilaginous structure attached to the periphery of the osseous acetabular rim,plays an important role in maintaining hip stability,pressure balance,and growth.In the developmental dysplasia of the hip(DDH),the abnormal stress on the acetabulum after dislocation or subluxation of the femoral head causes the labrum to become hypertrophy and degeneration,which become the obstacle of the central reduction.However,the treatment of acetabular labrum in DDH is still controversial.This article reviews the anatomical and imaging features of the normal labrum and DDH labrum and its effect on DDH treatment.
