Abstract

BACKGROUND

To examine the relationship of the Böhler's angle with age, sex, and laterality, and to analyze the interrater agreement.

METHODS

After 248 digital lateral radiographs of the foot were submitted to exclusion criteria, three raters independently measured the Böhler's angle on the remaining 130 X-rays in PACS. The variables were analyzed with correlation coefficients, and one-way ANOVA. The repeated measures of ANOVA were computed across age groups (30-39, 40-49, 50-59, and 60-69 years). The interrater agreement was calculated using intraclass correlation coefficient (ICC).

RESULTS

The mean value of the Böhler's angle was 34±5° (21-46°). It was not related to age (in general [p=0.057], and across groups [p from 0.107 to 0.122]), sex (p=0.344; p=0.342), and laterality (p=0.618; p=0.617). The interrater reliability was almost perfect (ICC=0.94).

CONCLUSIONS

The Böhler's angle was not related to age, sex, and laterality, whereas the interrater agreement was almost perfect.

摘要

背景

研究跟骨角与年龄、性别及左右侧的关系，并分析评估者间的一致性。

方法

248例足部数字化侧位X线片经排除标准筛选后，三名评估者独立在PACS系统中测量剩余130例X线片上的跟骨角。采用相关系数及单因素方差分析对变量进行分析。对各年龄组（30 - 39岁、40 - 49岁、50 - 59岁和60 - 69岁）计算重复测量方差分析。使用组内相关系数（ICC）计算评估者间的一致性。
