We evaluated the relationship and the difference between measurements of version angles (VAs) of the acetabular components in total hip arthroplasty taken using 2 different methods. One VA was measured on an anteroposterior radiograph of the hip joint (VAP) and the other on a cross-table lateral radiograph (VCL) in 97 hips after surgery (clinical data) and 6 sawbone pelvic models (model data). There was a positive correlation between VAP and VCL for both data. Mean and standard deviation of the differences (VCL - VAP) between the 2 measurements were 5 degrees +/- 4.2 degrees in clinical data and -0.01 degrees +/- 0.32 degrees in model data. These differences on clinical data should be taken into consideration when comparing VAs in the literature using different measuring methods.
我们评估了在全髋关节置换术中使用两种不同方法测量髋臼组件的版本角度（VA）之间的关系和差异。在97例术后髋关节（临床数据）和6个锯骨骨盆模型（模型数据）中，一个VA在髋关节前后位X线片上测量（VAP），另一个在交叉台侧位X线片上测量（VCL）。两种数据的VAP和VCL之间均呈正相关。临床数据中两次测量之间差异（VCL - VAP）的平均值和标准差为5度±4.2度，模型数据中为-0.01度±0.32度。在使用不同测量方法比较文献中的VA时，应考虑临床数据中的这些差异。
