BACKGROUND
Few methods have been described for measuring hindfoot alignment from an anteroposterior view. The objective of this study was to compare two methods of angular measurement based on the views of Meary and Saltzman.
METHODS
Thirty asymptomatic volunteers were included. Four radiographs were performed: the views of Meary and Saltzman with parallel feet and with the Fick correction. The reproducibility was determined by the inter- and intraobserver variability (ICC).
RESULTS
Meary's method revealed a mean valgus angulation of 3.9° (SD 3.47°). The reliability was extremely variable with a mean ICC of 0.59. The best reproducibility was obtained with Meary's method with and without Fick correction.
CONCLUSION
The results of this study show that the reliability of the angular measurements depends on the radiographic view and measurement method chosen. The lateral Fick correction did not counteract the influence of tibial rotation. The same method should be used consistently.
背景
很少有方法被描述用于从前后位视图测量后足对线。本研究的目的是比较基于Meary和Saltzman视图的两种角度测量方法。
方法
纳入30名无症状志愿者。进行了四张X线片检查：双脚平行时的Meary和Saltzman视图以及采用Fick校正的视图。通过观察者间和观察者内变异性（ICC）确定可重复性。
结果
Meary方法显示平均外翻角度为3.9°（标准差3.47°）。可靠性变化极大，平均ICC为0.59。采用有或没有Fick校正的Meary方法可获得最佳可重复性。
结论
本研究结果表明，角度测量的可靠性取决于所选择的X线片视图和测量方法。外侧Fick校正并未抵消胫骨旋转的影响。应始终使用相同的方法。
