Evaluation of sex criteria on the basis of pelvic bone radiological imaging in modern anatolian populations

Sex estimation plays an important role in positive identification, which is especially important in terms of guiding the solution of forensic cases. It is known that the pelvis is used for sex estimation due to the prominent sexual dimorphism on the pelvis. In this context, in order to predict sex, 24 anthroposcopic evaluations were made and 23 osteometric measurements were taken on the pelvis. These measurements were taken over the pelvic openings, os coxae, and sacrum. Due to the need for current data of the society at the point of enlightening forensic events, this study aims to reach information about the modern Anatolian society and to create an index with this information. In line with the targeted purposes, in this study, the patients who were included in the radiological observation database of the Akdeniz University Medical Faculty Hospital between July - November 2019 were randomly selected from among those who met the research criteria. Anthroposcopic evaluations and anthropometric measurements were carried out on pelvic CT images of 120 women and 120 men in total. Results were obtained by performing Paired Sample and Independent Sample T Test, Correlation Analysis, and Discriminant Function Analysis (DFA) with the help of the IBM SPSS Statistics 22 program. According to the results, statistically significant differences were observed in the majority of measurements (19/23) taken over the pelvic openings, os coxa, and sacrum between women and men, and this was interpreted as an indicator of sexual dimorphism. The sexes of 86% of men and 85% of women were correctly predicted with the right ischiopubic index. With the left ischiopubic index, 84% of men and 83% of women were correctly predicted. According to the DFA results, the variable with the highest explanation rate in the sex estimation in the coxae was found to be the height of the coxa. The results of the analyzes were compared with other studies in the literature, and their similarities and differences were noted.
