The study was done on CT and x-rays, in a number of 200 cases (98 males 102 females), the benchmarks followed being described in relation to the comparative right/left sex and by age groups. We found sexual differences in the size of carpal bones, in most cases, the dimensions being larger, with variable differences, most frequently 1-2 mm, in favor of the male. We also found special dimensions between the two parts, either related to height or the width of the same carpal bone, as well as dimensional differences between the age groups studied. Cases of total right/left symmetry (in which the width and height of a carpal are equal to the two sides, right and left) were encountered in relatively uncommon percentages, the percentages being characteristic of each carpal bone. Total symmetries were more common in females, finding them more common 6% of cases in female. The most common cases of symmetry were found in the trapezoidal bone, in a total percentage of 17% of cases, in female being in 19.61% of cases, and in male 14.29% of cases. The lowest percentage of similarity i met in the semi-monthly (3% of cases), in male being 4.08% of cases, and in female in 1.96% of cases.

The lowest percentage of similarity i met in the semi-monthly (3% of cases), in male being 4.08% of cases, and in female in 1.96% of cases. Depending on the age group, symmetry cases were most commonly found in age groups 10-18 years (12% of cases), 21-29 years (13% of cases), 30-39 years (14% of cases) and 41-49 years (16% of cases). The reduced percentage symmetries I encountered over the age of 59: 4% of cases in the age group 62-69 years and 6% of cases, in the age groups, 62-69 years and 72-78 years. These asymmetries would probably be due to rheumatic morphometric changes that frequently affect the age over 60 years. [ABSTRACT FROM AUTHOR]
