The body of the lumbar vertebrae, like that of the cervical vertebrae, is wider in the transverse than the sagittal diameter. The dimensions of the vertebral body have been measured in skeletal populations of several ethnic groups (8, 30, 64, 96). The mean values obtained in the various studies are comparable, although not equal. This probably depends, to a large extent, on constitutional characteristics related to racial factors. An overall analysis of the results indicates that the transverse and sagittal diameters, as well as the height, as measured on the anterior aspect of the vertebral body, show a regular or only slightly irregular increase from L1 to L5 in all human populations.
