背景：通过站立 X 光片准确测量扁平足，可以正确诊断病情并评估重建手术。方法：使用盲法观察者将有症状的成人平足患者的站立放射学测量值与对照组进行比较。结果：在侧位片上，患者组和对照组的距骨与第一跖骨角、跟骨倾斜角和内侧楔骨第五跖骨高度存在显着差异。侧位X光片上距骨与第一跖骨角度的差异最具统计学意义（患者组21.1 +/- 10.8度，对照组7.1 +/- 10.7度，p < 0.0001），读数之间具有良好的相关性（观察者内0.75，观察者间0.83）。在前后位（AP）X线照片上，距骨头暴露距离是这些组之间最显着不同的测量值。结论：这些发现支持这样的假设：距骨第一跖骨角是有症状的成人平足患者的准确放射学识别标志。
Background: The accurate measurement of flatfoot on standing radiographs allows correct diagnosis of the condition and evaluation of reconstructive procedures. Method: The standing radiographic measurements of patients with symptomatic, adult flatfoot were compared to controls using blinded observers. Results: On the lateral radiograph, the talar-to-first metatarsal angle, the calcaneal pitch angle, and the medial cuneiform-fifth metatarsal height differed significantly between the patient group and the controls. The difference in the talar-to-first metatarsal angles on lateral radiographs was the most statistically significant (patient group 21.1 +/- 10.8 degrees and control 7.1 +/- 10.7 degrees, p < 0.0001) with good correlation between readings (intraobserver 0.75, interobserver 0.83). On the anteroposterior (AP) radiograph, the talar head uncoverage distance was the most significantly different measurement between these groups. Conclusions: These findings support the hypothesis that the talar-first metatarsal angle is an accurate radiographic identifier of patients with symptomatic, adult flatfoot.
