Eleven patients with tears of the acetabular labrum are discussed and the syndrome of the torn labrum is defined. In all cases the lesion was associated with acetabular dysplasia, and a constant early radiological sign was a cyst in the lateral aspect of the acetabulum. The diagnosis was confirmed by arthrography. It is suggested that these tears are degenerative, occurring as a consequence of abnormal stresses imposed by the uncovered lateral portion of the femoral head. Once a tear is present a localised stress point occurs on the femoral head, leading rapidly to degenerative arthritis.
本文讨论了11例髋臼盂唇撕裂患者，并对盂唇撕裂综合征进行了定义。所有病例中，病变均与髋臼发育不良相关，髋臼外侧出现囊肿是一个持续存在的早期影像学征象。关节造影证实了诊断。研究表明，这些撕裂是退行性的，是由于股骨头未覆盖的外侧部分施加的异常应力所致。一旦出现撕裂，股骨头就会出现局部应力点，迅速导致退行性关节炎。
