目的研究股骨髋臼撞击（一种伴有髋臼和股骨之间异常基台的髋关节疾病）的发生率，并评价与股骨髋臼撞击相关的影像学特征在有髋臼和没有髋臼撞击的日本患者中的差异。材料和方法我们使用计算机断层成像检查了每侧1178髋（男性695人，女性483人，平均年龄58.2岁）。通过测量髋外侧中心边缘角、髋臼指数、髋臼转角、α角和股骨头颈偏移量对髋关节形态进行放射学评估。HPs定义为位于股骨颈前皮质下方，被硬化骨包围的圆形或椭圆形囊性病变。结果所有放射测量的类内和类间重现性均可接受（ICC: 0.71-0.98）。所有受试者的hp患病率为13.9%，男性（18.1%）显著高于女性（7.8%,p< 0.001）。hp在男性（p< 0.001）和老年人（p< 0.005）中较大。在患有hp的受试者中，整个队列和男性的α角较大，股骨头颈偏移和偏移比较小。Logistic回归分析显示，所有受试者的放射凸轮型FAI与hp之间存在相关性（优势比：1.86,p< 0.001）。结论：我们揭示了hp的患病率，并表明在这个日本队列中，它对男性有偏爱。股骨头非球形或小头颈偏移在hp患者中比无hp患者更常见。
ObjectiveTo examine the prevalence of herniation pits (HPs) and to evaluate differences in radiographic features related to femoroacetabular impingement—a hip disorder with abnormal abutment between the acetabulum and femur—between hips with and without HPs in a convenience sample of Japanese patients.Materials and methodsWe reviewed 1,178 hips on each side (695 men, 483 women; mean age, 58.2 years) using computed tomographic images. The radiological assessments of hip morphology were performed by measuring the lateral center edge angle, acetabular index, acetabular version, alpha angle, and femoral head-neck offset. HPs were defined as the round or oval cystic lesions surrounded by sclerotic bone located below the anterior femoral neck cortex.ResultsIntraclass and interclass reproducibility of all radiographic measurements was acceptable (ICC: 0.71–0.98). The prevalence of HPs was 13.9 % in all subjects and was significantly higher in men (18.1 %) than in women (7.8 %;p< 0.001). HPs were larger in male (p< 0.001) and elderly subjects (p < 0.005). In subjects with HPs, the alpha angle was larger and femoral head-neck offset and offset ratio were smaller in the cohort overall and in men. Logistic regression analysis revealed the association between radiological cam-type FAI and HPs in all subjects (odds ratio: 1.86,p< 0.001).ConclusionsWe revealed the prevalence of HPs and showed it has a predilection for men in this Japanese cohort. Femoral head asphericity or small head-neck offset was more common in subjects with HPs than those without HPs.
