Sexing of ulna by multivariate analysis

ABSTRACT

All bones show sexual dimorphism but hip bone, sacrum and skull are valuable in accurate diagnosis. Different workers studied different bones and determined the sex with some accuracy [ranging from 70 - 100%]. They used the following methods:-Traditional-non material method [Morphological], and Metrical method [Anthropological]. 193 ulnae of known sex available in bone bank of the department of anatomy, government medical college, Aurangabad, India are studied and various dimensions are measured in this study. The methods used for analysis of sexing of ulnae are univariate, multivariate and morphological methods. It was found that 88.1% accuracy of sexing can be done even if one ulna is studied, and changing combinations of 4 groups doesn't influence the percentage of accuracy of sexing. From the above results, we conclude that the multivariate analysis is the best possible method for sexing of ulnae
