It has been suggested that variances in the anatomy of the acetabulum determine the type of hip fracture in elderly patients. Based on this concept, an overly anteverted acetabulum would lead to impingement of the femoral neck against the posterior rim of the acetabulum, causing a femoral neck fracture, whereas with a retroverted acetabulum, external rotation of the hip would be limited by the capsular tissues attached to the trochanteric region, causing a trochanteric fracture. To test the hypothesis that acetabular version predicts hip fracture type in elderly patients, we measured acetabular version using computed tomography scans for 135 patients with hip fracture. Logistic regression analysis was used to check for an association between version angle and fracture type. No significant relationship between acetabular version and fracture type was found. Therefore, we conclude that acetabular version angle does not predict hip fracture type in the elderly, and our data do not support the impingement concept as the mechanism of hip fractures.
有人提出，髋臼解剖结构的差异决定了老年患者髋部骨折的类型。基于这一概念，髋臼过度前倾会导致股骨颈撞击髋臼后缘，从而引起股骨颈骨折，而髋臼后倾时，髋关节的外旋会受到附着于转子区的关节囊组织的限制，导致转子间骨折。为了验证髋臼旋转角度可预测老年患者髋部骨折类型这一假设，我们对135例髋部骨折患者进行了计算机断层扫描，测量了髋臼旋转角度。采用逻辑回归分析来检验旋转角度与骨折类型之间的关联。未发现髋臼旋转角度与骨折类型之间存在显著关系。因此，我们得出结论，髋臼旋转角度不能预测老年人的髋部骨折类型，我们的数据不支持撞击概念作为髋部骨折的机制。
