Measurements of the curvature of the lumbar spine are useful in the investigations of low back pain. It is unclear whether the degree of lumbar lordosis, sacral inclination and lumbosacral angulation are the same for all normal adults. Radiographic studies were carried out on the lumbar spines of subjects aged 9-61 years. Mean and 95% tolerance ranges of the values of lumbar lordosis, lumbosacral angle and sacral inclination for adult age groups up to the sixth decade are given. The results showed that all three parameters varied steadily with age. The pattern of changes differed in males and females. Females had greater angles than males. Sacral inclination appeared to be a more important determinant of the degree of lumbar lordosis. All three parameters showed a tendency to decrease after the sixth decade. The significance of the findings is discussed.
腰椎曲度的测量对于腰痛的研究很有用。目前尚不清楚所有正常成年人的腰椎前凸程度、骶骨倾斜度和腰骶角是否相同。对9至61岁受试者的腰椎进行了影像学研究。给出了直至第六个十年的各成年年龄组腰椎前凸、腰骶角和骶骨倾斜度值的平均值及95%容许范围。结果表明，所有这三个参数均随年龄稳步变化。男性和女性的变化模式不同。女性的角度大于男性。骶骨倾斜度似乎是腰椎前凸程度更重要的决定因素。所有这三个参数在第六个十年之后都呈现出下降趋势。文中讨论了这些发现的意义。
