Currently, many techniques for the diagnosis of carpal disorders have been developed.

Plain radiograph is the most simple anti low-cost procedure that offers various

information on the normal wrist. Nonetheless, a sufficient amount of morphometric

database for Koreans has not been studied. In this study, the authors reviewed 100

cases of plain posteroanterior radiograph of the wrist in normal Korean adults for both

sexes in order to establish normal databases. Various parameters were measured, and

comparisons between the sexes, age groups, foreign databases and other domestic

databases were made. The results were as follows.

1. In all measurements of the length and ratio except ulnar parlance, there were

significant differences between the sexes. But there was no significant difference

between the sexes in angular measurements. No significant difference in measurements

were found among the groups based on their age.

2. The average ulnar variance was 0.6 ㎜, and it was higher than Europeans and


3. The average carpal height ratio was 53.5% and significantly lower in females, but

the revised carpal height ratio was higher. This means that the length of the capitate is

shorter and the length of the third metacarpal bone is relatively longer in females, if the

carpal height is constant.

4. The carpal-radial distance ratio, the carpal-ulnar distance ratio, and the carpal

width-carpal height ratio were significantly lower in females. This means that the carpal

width is relatively narrower in females.

The authors hope that information concerning normal roentgenographic measurements

of the wrist can help to diagnose the carpal disorders including the diseases appearing

carpal collapse or carpal translation and to design wrist implants.
