Abstract

The present study was carried out to clarify the anatomical changes of lumbar intervertebral discs by aging. Anterior height, posterior height, anteroposterior diameter of intervertebral discs were measured on 512 normal plain lateral radiographs of lumbosacral spine. And the indices of disc wedging and relative disc height were calculated. There was a cephalocaudal gradient of increase in the indices of disc wedging in all age groups. The indices of relative disc height were constant at all lumbar levels. These suggest that the lower disc is more wedge shaped and the height of discs changes in the constant ratio with that of vertebral body.
