QUEIROZ, Antonio et al. Sex determination by measures and weight verification of sternum bone.Brasil. Med. leg. Costa Rica [online]. 2005, vol.22, n.1, pp.73-78. ISSN 2215-5287.

Human gender determination is one of the main attributions of forensic odontologists and forensic pathologists responsible for the anthropological analysis of skeletons, parts and fragmented bones. One of the bones that can and must be analyzed is the sternum, considering its particular characteristics. In the present study we’ve measured and weighed 100 sternums, 50 belonging to female gender and 50 to male gender proceeding from Cuiabá-MT, with age varying between 19 and 103 years. It was verified that the measure of the center of the chamfer of the insertion of the first to the left costal arc and the weight of the manubrium and body of sternum, are highly significant, becoming parameters to determine the gender. A mathematical formula was also obtained that permitted to determine the gender in future analyses with indices of 69,2%. (SEX DETERMINATION BY MEASURES AND WEIGHT VERIFICATION OF ESTERNUM BONE)
