The sagittal plane of the growing spine was studied from standardized radiographs of 670 normal subjects to establish standards of reference for thoracic kyphosis, lumbosacral lordosis, and sacral inclination. Cobb's method of measuring spinal deformities was compared with new indices of kyphosis and lordosis that take into consideration the length and width of each curve. Boys and girls had comparable degrees of kyphosis. Although girls initially had higher degrees of lordosis and sacral inclination, by maturity these measurements were similar in both sexes. Significant correlations were found between kyphosis and lordosis and between lordosis and sacral inclination, indicating that these curvatures tend to balance each other.
通过对670名正常受试者的标准化X线片研究生长中脊柱的矢状面，以建立胸椎后凸、腰骶前凸和骶骨倾斜度的参考标准。将测量脊柱畸形的Cobb方法与考虑每条曲线长度和宽度的新的后凸和前凸指数进行比较。男孩和女孩的后凸程度相当。虽然女孩最初的前凸和骶骨倾斜度较高，但到成年时，两性的这些测量值相似。发现后凸与前凸之间以及前凸与骶骨倾斜度之间存在显著相关性，表明这些曲度倾向于相互平衡。
