Background: Determination of biological sex is one of the most important determinations to be made from human remains and is an essential first step in the development of the biological profile in forensics, anthropology and bioarchaeology. The aim of this study was to determine whether sexing of unknown adult human Ulna bones can be done by applying values of morphometric parameters and formulae generated by present study on adult human Ulna bones of known sex and to find out the best parameters for sex determination.
Methods: Various metric measurements were recorded using osteo metric board, measuring tape, non elastic thread, sliding calipers and vernier calipers on adult human Ulna bones.
Results: Sex was correctly estimated by using stepwise discriminant function analysis, for the Ulna 95.6 % of males and 89% of females, with a total accuracy of 93.2 %.
Conclusions: Present study exhibited better classification accuracy for multiple variables than those of single variables. In the Ulna, the most discriminating variables in stepwise analysis are the Weight, Physiological length and Minimum olecranon breadth.
