继发于髋臼后倾的髋臼覆盖物过多导致钳形撞击，这可能导致髋关节早期骨关节炎。我们的目的是确定髋臼翻转和髋关节骨关节炎之间是否存在关系。使用图像处理和分析软件，我们研究了117例年龄小于65岁的患者接受CT仿真结肠镜检查的髋关节CT图像。髋臼后倾的18个髋关节的平均CT关节间隙比髋臼对线正常的99个髋关节的平均CT关节间隙窄（p < 0.0001）。右髋髋臼扭转与右髋关节平均间隙的相关系数r = 0.46（p < 0.01），左髋髋臼扭转与左髋关节平均间隙的相关系数r = 0.31（p = 0.02）。髋臼后倾与髋关节骨关节炎的放射学证据有关。了解髋关节骨关节炎的力学基础，可以早期治疗潜在的结构异常，并防止退行性疾病的进展。
Excessive acetabular cover secondary to a retroverted acetabulum causes pincer impingement, which may cause early osteoarthritis of the hip. Our aim was to determine if there was a relationship between acetabular version and osteoarthritis of the hip. Using image processing and analysis software we studied 117 CT images of the hip in patients aged less than 65 years who had undergone a CT virtual colonoscopy. The mean CT joint space of the 18 hips with acetabular retroversion was narrower compared with the 99 hips with normal acetabular alignment (p < 0.0001). A correlation of r = 0.46 (p < 0.01) was found between right hip acetabular version and the mean right hip joint space and of r = 0.31 (p = 0.02) between left hip acetabular version and the mean left hip joint space. Acetabular retroversion is associated with radiological evidence of osteoarthritis of the hip. An understanding of the mechanical basis of osteoarthritis of the hip allows early treatment of the underlying structural abnormality and prevents progression of the degenerative condition.
