Abstract

We aimed to determine the normal ranges of radial and ulnar deviation of the wrist in relation to the ulnar variance. A total of 102 healthy subjects (204 wrists) were included in the study. The ranges of radial and ulnar deviation of the wrists were measured using a universal goniometer. Ulnar variance was assessed manually or radiographically, and recorded as ulna minus, ulna plus or ulna minus/plus. When the ranges of radial and ulnar deviation were compared with ulnar variance, ulnar deviation was greater in ulna minus subjects and radial deviation was greater in ulna minus/plus subjects. There was no significant difference in the total range of radio-ulnar deviation. The results of this study indicate that ulnar deviation is greater in ulna minus wrists, and we suggest that ulnar variance should be recorded alongside measurements of radial and ulnar deviation.
