Abstract
Forensic Anthropology is the branch of Physical Anthropology that deals with criminal examinations of bones and charred corpses or those in an advanced state of decomposition. Sex estimation is an essential step in identifying unknown individuals and often depends on the presence of highly dimorphic bones such as the pelvis and skull. In the absence of the skull and pelvis, isolated sacrum can be used to estimate sex, as it is a bone favored for preservation. The objective of our study was to perform an osteometric study on dry adult sacrum and relate the results to sexual dimorphism. For this we used a sample of 200 dried sacrums, 130 male and 70 female, all belonging to the Center for Forensic Anthropology at FAP-Araripina. We performed three linear measurements on these bones: maximum height, maximum width and transverse diameter of the body of the first sacral vertebra. All measurements were taken with the aid of a precision digital caliper graduated in millimeters from the Vonder brand. According to our results, the average maximum height was greater in males (117.0mm), while the maximum width and transverse diameter of S1 were higher in females with 111.1mm and 44.1mm respectively. We hope that more studies on our population will be carried out, especially in different regions, due to the large territorial area of Brazil and the great miscegenation that exists in our country.
