根据 247 名 35-54 岁男性和女性股骨头顶点水平的 X 光片测量腿长不均。 其中，53 人从未有过任何腰背问题，但他们的腿长不平等程度有相当大的差异（平均 SD，5.5 +/- 4.1 毫米；范围，高达 20 毫米）。 这组无症状个体与过去 12 个月内患有致残性腰痛 (LBP) 的 78 人组没有区别（平均 SD，5.3 +/- 4.0 毫米；范围高达 17 毫米）。 对于腿长不等增加 5 毫米，过去 12 个月内曾经患有 LBP 和致残性疼痛的调整后相对风险（比值比）分别为 0.78（95% 置信区间，0.43-1.17）和 1.02（0.68-1.38）。 这项研究的结果使轻度腿长不平等与腰痛之间的关联值得怀疑。
Leg-length inequality was measured from radiographs at the level of the vertices of the femoral heads in 247 men and women aged 35-54 years. Of these, 53 had never had any low-back problem, but they had considerable variation in leg-length inequality (mean SD, 5.5 +/- 4.1 mm; range, up to 20 mm). This group of symptom-free individuals did not differ from a group of 78 persons who had disabling low-back pain (LBP) during the previous 12 months (mean SD, 5.3 +/- 4.0 mm; range, up to 17 mm). The adjusted relative risks (odds ratios) of having LBP ever and of disabling pain during the last 12 months were 0.78 (95% confidence interval, 0.43-1.17) and 1.02 (0.68-1.38), respectively, for an increase of 5 mm in leg-length inequality. The results from this study make an association between mild leg-length inequality and LBP questionable.
