BACKGROUND
A new radiographic view was proposed to evaluate the coronal plane alignment of the hindfoot under weightbearing conditions.
METHODS
We studied 46 feet of individuals with normal appearing asymptomatic feet. On the antero-posterior roentgenogram using this new method, the line from the top of the sustentaculum tali to the lateral-inferior end of the posterior articular surface of the talus was obtained as the standard line showing varus or valgus of the calcaneus. We defined the angle between the longitudinal axis of the tibia and the standard line as described above as Varus-Valgus angle (V-V angle).
RESULTS
The mean (±SD) V-V angle of the 46 feet studied was 76.4 (±3.6) degrees.
CONCLUSION
The findings from this study indicate that it is possible to estimate the alignment of the hindfoot quantitatively by comparing individuals to the mean V-V angle that we calculated in our sample, which was 76.4 degrees.
背景
提出了一种新的放射影像学视图，以在负重条件下评估后足的冠状面排列。
方法
我们研究了 46 例外观正常、无症状的足部。在使用这种新方法的前后 X 线片上，从跟骨的距骨下外侧后关节面的跟骨顶到距骨下外侧后关节面的顶的线作为标准线，显示跟骨的内翻或外翻。我们将胫骨的纵轴与上述标准线之间的夹角定义为内翻-外翻角（V-V 角）。
结果
研究的 46 只脚的平均（±SD）V-V 角为 76.4（±3.6）度。
结论
本研究结果表明，通过将个体与我们在样本中计算得出的平均 V-V 角进行比较，有可能对后足的排列进行定量估计，我们计算出的平均 V-V 角为 76.4 度。
