✦ Synopsis
Sex identification of human long bones has been studied by several investigators. Measurements of the radius and the ulna have also been reported as an indicator of sex by reference to separate parameters and/or to combinations of the parameters of a single bone.
This study was designed to determine whether the radius and the ulna can provide reliable information for the sexing of human bones, as can the lower leg bones, if the forearm measurements include the weight index of the two bones as a parameter. The materials consisted of the dried radii and ulnae of 20 recently deceased Japanese males and 20 similar females. Almost all the dimensions exhibited statistically significant sex differences. The radio-ulnar weight index did not, however, differ between the sexes. In discriminant analysis, the rate of correct sex discrimination based on distances between various pairs of points was not improved by the inclusion of the radioulnar weight index. Therefore, the radio-ulnar weight index cannot be recommended as a parameter for the sexing of human bones.
