Herniated lumbar disc or definite sciatica was diagnosed in 16 of 195 men and women who had reported a history of low-back pain in a health survey. Measurements related to the size and shape of the lumbar spinal canal were subsequently made from the survey radiographs and compared between various types of back syndromes. Age, body height, body mass index, occupation, and parity of women were controlled as potential confounders using analysis of covariance. Several dimensions of lumbar vertebral canals appeared more shallow in the subjects who had herniated disc or definite sciatica than in the other ones. In particular, the interarticular distance of the first sacral vertebra was found to be narrowed in the presence of sciatica, the difference of the adjusted distances to the other back pain category being in men 30.5 mm versus 35.1 mm (P = 0.02) and in women 23.8 mm versus 30.3 mm (P = 0.002), respectively.
在一项健康调查中报告有腰痛病史的195名男性和女性中，有16人被诊断出腰椎间盘突出或明确的坐骨神经痛。随后从调查X光片中测量了与腰椎管大小和形状相关的数据，并在各种类型的背部综合征之间进行了比较。使用协方差分析将年龄、身高、体重指数、职业和女性的生育状况作为潜在混杂因素进行控制。与其他受试者相比，患有椎间盘突出或明确坐骨神经痛的受试者的几个腰椎管维度似乎更浅。特别是，发现存在坐骨神经痛时第一骶椎的关节间距离变窄，与其他背痛类别相比，调整后距离的差异在男性中分别为30.5毫米对35.1毫米（P = 0.02），在女性中分别为23.8毫米对30.3毫米（P = 0.002）。
