Abstract

Background: The skeletal dimensions remain an important to identify the victim in cases of disastars where key identification points of the body is lost. Sex determination is the first step in identifying a body.The main objective of this paper was to generate race-specific femoral database and to determine sexual demorphism of femur in South Africans ethnic groups and South Africans of Europeon decent. Six standard femoral variables were used; bone length, maximum head diameter, bicondylar breadth, head-neck length, lateral and medial condylar length. Ten South African ethnic groups (Zulu, Tswana, Swazi, Sotho, Xhosa, Dart Peti, Shan, Dart Shan, Ndebele and Venda) were considered as the independent variable and South Africans of European Descent. A total of 235 male femura and 160 female femora were obtained from Dart's Collection at Witwatersrand University. Results: Male dimensions were significantly larger than females dimensions in all the ethnic groups (p 0.001) except Shan and Dart Shan. Strong correlation was observed between head diameter and bone length. Conclusions: This study developed a database for sexual demorphism in femura among 10 South African ethnic groups and SAED. Results showing male dimensions larger than females. This is the first such study elaborating the race-specific sexual demorphism in South African ethnic groups.
