Among radiographic views available for assessing hindfoot alignment, the antero-posterior weight-bearing view with metal cerclage of the hindfoot (Méary view) is the most widely used in France. Internationally, the long axial view (LAV) and hindfoot alignment view (HAV) are used also. The objective of this study was to compare the reliability of these three views.
The Méary view with cerclage of the hindfoot is as reliable as the LAV and HAV for assessing hindfoot alignment.
All three views were obtained in each of 22 prospectively included patients. Intra-observer and inter-observer reliabilities were assessed by having two observers collect the radiographic measurements then computing the intra-class correlation coefficients (ICCs).
The intra-observer and inter-observer ICCs were 0.956 and 0.988 with the Méary view, 0.990 and 0.765 with the HAV, and 0.997 and 0.991 with the LAV, respectively. Correlations were far stronger between the LAV and HAV than between each of these and the Méary view. Compared to the LAV and HAV, the Méary view indicated a greater degree of hindfoot valgus.
Intra-observer reliability was excellent with both the LAV and HAV, whereas inter-observer reliability was better with the LAV. Excellent reliability was also obtained with the Méary view. Combining the Méary view to obtain a radiographic image of the clinical deformity with the LAV to measure the angular deviation of the hindfoot axis may be useful when assessing hindfoot malalignment. A comparison of the three views in a larger population is needed before clinical recommendations can be made.
II, prospective study.
在可用于评估后足对线的X线片视图中，后足金属环扎的前后位负重视图（梅里视图）在法国使用最为广泛。在国际上，也使用长轴视图（LAV）和后足对线视图（HAV）。本研究的目的是比较这三种视图的可靠性。
后足环扎的梅里视图在评估后足对线方面与LAV和HAV一样可靠。
对22例前瞻性纳入的患者均获取了这三种视图。通过让两名观察者收集X线测量数据，然后计算组内相关系数（ICC）来评估观察者内和观察者间的可靠性。
观察者内和观察者间的ICC在梅里视图中分别为0.956和0.988，在HAV中分别为0.990和0.765，在LAV中分别为0.997和0.991。LAV和HAV之间的相关性远强于它们与梅里视图之间的相关性。与LAV和HAV相比，梅里视图显示出更大程度的后足外翻。
LAV和HAV的观察者内可靠性均极佳，而LAV的观察者间可靠性更佳。梅里视图也获得了极佳的可靠性。在评估后足对线不齐时，将梅里视图用于获取临床畸形的X线图像，同时结合LAV测量后足轴的角度偏差可能会很有用。在做出临床建议之前，需要在更大的人群中对这三种视图进行比较。
