原发性髋关节骨关节炎可能有结构基础。据推测，髋臼后倾的放射学外观可以通过改变髋臼壁的形态特征来产生，并且根据骨盆的前后位X光片所定义的髋臼后倾与髋部骨关节炎相关。使用骨盆模型来模拟正常的、增强的、缺陷的和旋转的髋臼壁，并拍摄放射线照片以将修改后的髋臼壁的投影与已知的后倾髋臼的平片放射线外观进行比较。将特发性髋骨关节炎全髋关节置换术前拍摄的 131 张高质量骨盆前后位 X 线照片与 99 张因非骨科原因拍摄的高质量 X 线照片进行比较。放射学检查显示髋臼后倾的患病率在特发性髋骨关节炎患者中为 20%，在普通人群中为 5%。骨盆前后位X光片上髋臼后倾的出现是由于髋臼后壁缺陷造成的。放射学髋臼后倾与髋骨关节炎之间存在统计学上显着的关联。这些发现适用于了解髋骨关节炎的机械病因，以及髋臼周围截骨术和全髋关节置换术期间的手术技术。
Primary osteoarthritis of the hip may have a structural basis. It was hypothesized that the radiographic appearance of acetabular retroversion could be created by altering the morphologic features of the acetabular walls, and that acetabular retroversion, as defined on an anteroposterior radiograph of the pelvis, is associated with osteoarthritis of the hip. A model pelvis was used to simulate normal, augmented, deficient, and rotated walls of the acetabulum, and radiographs were taken to compare the projections of the modified acetabular walls with the known plain radiographic appearance of a retroverted acetabulum. One hundred thirty-one good quality anteroposterior radiographs of the pelvis taken before total hip arthroplasty for idiopathic hip osteoarthritis were compared with 99 good quality radiographs taken for nonorthopaedic reasons. The prevalence of radiographic acetabular retroversion is 20% among patients with idiopathic hip osteoarthritis and 5% among the general population. The appearance of acetabular retroversion on an anteroposterior radiograph of the pelvis is created by deficiency of the posterior wall of the acetabulum. There is a statistically significant association between radiographic acetabular retroversion and hip osteoarthritis. These findings have applicability to understanding the mechanical etiology of hip osteoarthritis, and to surgical technique during peri-acetabular osteotomy and total hip arthroplasty.
