Degree of vertebral wedging of the dorso-lumbar spine

From a random sample consisting of 164 persons, the degree of vertebral wedging was calculated as the ratio between the heights of the anterior and posterior aspects of the vertebrae Th8 to L3. The normal values and confidence limits are described. The degree of wedging was significantly greater at almost all levels in the male group than in the female group. No positive relationship to age was found.
