The role of bone shape in determining gender differences in vertebral bone mass.

Dual-energy X-ray absorptiometry (DXA) measures of bone mineral density (BMD) in children fail to account for growth because bone depth is unmeasured. While multiple adjustment methods have been proposed using body or bone size, the effect of vertebral shape is relatively unknown. Our study aimed to determine gender differences in vertebral shape and their impact on areal BMD (aBMD).
