Abstract
Vertebral heights were measured on lateral spine radiographs covering T4—L5 in 113 healthy Caucasian volunteers (73 females aged 22–80 years, and 40 males aged 22–79 years). Vertebral heights were significantly higher in men than in women (p < 0.001). In women, a significant correlation was found between the height of T4 and the heights of the other vertebrae with correlation coefficients ranging from 0.71 (T5) to 0.38 (L1) and similar figures were found in males. Both the absolute and relative vertebral heights in this series were close to those reported by others. Selection of subjects and racial, environmental, and technical factors may explain the small differences. It is concluded that vertebral heights can be predicted from vertebrae rarely affected by spinal osteoporosis. Both relative and absolute vertebral heights differed between sexes. Although the reference values in this Scandinavian population were in agreement with previously reported data, small differences between populations were found, emphasizing the need for regional normative data.
