RESUMO

Forensic anthropology has an important and fundamental role in the identification of victims from mass disasters, such as automobile accidents, plane crashes, fire disasters, tumbling and other types of catastrophes, when the victims get so mutilated, that even the relatives are not able to recognized them. It is also essential in the analysis of cadavers in Iate decomposed state, bones or even in cases of isolated bones, when the authorities need to clear the victim s identity, and the probable cause of the death. Concerning bones, the analysis is conducted to identify the species, sex, age, height and racial type. The present work aims to determine the sex of human skeletons, through a quantitative research, in which measurements of some lineal greatness of pelvic bones were taken, in a sample Brazilian. Pelvic bones from 90 skeletons were measured, raging from 19 to 107 years old, 45 species were male and 45 were female, all of them had the identification data well known. The variable selected measurements were: sacre superior width; first sacral vertebra length and width; length and width; length and depth and, the distance from the anterior iliac spine to the pubic tuberculum. The success rates in the determination of the sex varied according to the statistical method and the variable measurements used. According to the discriminate analysis, the best results were obtained when the data from all the variable measurements were used, representing success in 87,8% for male and 82,8% for female. Using logistic regression, the success rates to determine the sex in general population were from 76,5% to male and 83,3% for female. Using the reliable intervals, the results showed that the variables: first sacral vertebra (width), acetabulum vertical diameter, obtured foramen diameter (Iength) and great ischiatic notch (depth) are good items to use and that the others are not recommended for studies of that nature. Therefore, it was concluded that the studied anatomical structures presented different degrees of sexual dimorphism and, that the results obtained by that quantitative analysis, made possible its use as a technique to determine the sex of human skeletons, either in the cases that the experts have complete pelvis, as well in those that there is just part of the pelvic bone for analysis
