Abstract :

Background: The successful identification of human skeletal remains relies on new methods for sex determination. Materials & methods: This research utilized 135 humeri from Bulgarian modern population (88 men, 47 women) to conduct a sex determination from the following features of distal humerus: olecranon fossa size and angle of the medial epicondyle. Results: The quantitative assessment of humeral anthroposcopic landmarks using Hand-held laser scanner can be used as a good sex predictor. In the present study the variables are subjected to discriminant function analysis. Discriminant function score equations were derived for individual and combined variables from the lower end of the humerus of the Bulgarian forensic sample. The combination of olecranon fossa size and angle of the medial epicondyle provided the best result with 85.7% accuracy. Discussion: The current forensic practice whereby criminals dismember the remains of their victims in an attempt to make their identification difficult requires that simple methods of sex determination from fragmented skeletal remains are available to forensic anthropologists and skeletal biologists. The distal humerus is an example of such bone fragments. The objectives of the present study were therefore to establish the standard numerical values for sex determination in Bulgaria.
