Clinical radiographic features of the wrist without osteoarthritis and its relations to age and sex in Japanese.

The purpose of this study was to identify a clinical radiographic features containing the measurements of carpal alignment, configuration, and joint space width of the wrist without osteoarthritis (OA) in Japanese. We also aimed to analyse age-related correlations in these parameters with reference to the difference between men and women. A total of 184 cases were analysed to establish the following relations: (1) Sex-related differences in the morphology and joint space width of the wrist without OA; (2) correlation coefficient between these parameters and age according to sex. This study suggests that carpal height ratio (CHR) was higher in men than in women. Also the ulnar variance (UV) increased and the radial inclination (RI) decreased with age in both men and women, and the volar tilt (VT) decreased with age in women.
