Which simple roentgenographic angle should be used to assess medial (varus) deviation of the first metatarsal in cases of hallux valgus has been a topic of debate. Measurements were made from roentgenograms of 100 symptomatic feet in women with hallux valgus. These were compared with similar measurements obtained from symptomatic normal feet of women of a similar age distribution. The hallux valgus angle was associated with medial deviation of the first metatarsal measured by all three of the parameters defined and tested, i.e., the intermetatarsal, metatarsus primus varus, and metatarsus omnis varus angles. Of these, the best measure was the intermetatarsal angle, which in the hallux valgus feet differed significantly from controls more than the other measurements. No evidence was found to support any concept of second metatarsal deviation from normal.
在拇外翻病例中，应使用哪种简单的X线角度来评估第一跖骨的内翻（内收）偏斜一直是一个有争议的话题。对100例有症状的拇外翻女性足部的X线片进行了测量。将这些测量结果与从年龄分布相似的有症状的正常女性足部获得的类似测量结果进行比较。拇外翻角与通过定义和测试的所有三个参数测量的第一跖骨内翻偏斜相关，即跖间角、第一跖骨内翻角和全跖骨内翻角。其中，最佳测量方法是跖间角，在拇外翻足部，该角度与对照组的差异比其他测量方法更显著。没有发现证据支持第二跖骨偏离正常的任何概念。
