title: Vertebral dimension differences between Caucasian populations, and between Caucasians and Japanese.
abstract: Various criteria have been proposed for using vertebral measurements to identify vertebral fractures. It is known that the normal distributions of vertebral heights and ratios vary with location within the spine. However, very little is known regarding the degree to which differences in these parameters may exist between populations. We report the vertebra-specific distributions of vertebral dimensions and ratios for Japanese-Americans, and compare these values to published data for Caucasians. The mean Japanese vertebral heights were 1 to 2 mm shorter than Caucasians, which may be due in part to the shorter stature of Japanese. However, differences in mean values were also observed between Caucasian populations. Furthermore, anterior/posterior vertebral height ratios differed between Caucasian studies, and between races. Additional studies are needed to determine to what degree these differences are due to technical and biological factors before criteria derived from one population can be used for identifying vertebral fractures in other populations of the same, or different, race.
