Forensic Assessment of Sex Using Pelvic X-rays in Libyan Population in Tripoli

Background: Estimation of sex represents one of the most important aspects of analysis in forensic anthropology. Selection of appropriate methods depends of course on what skeletal elements are present and what general age is represented. The pelvis is possibly the most accurate bone in the human body for age and sex determination, with the accuracy being 95% when completed. Aim: This study aimed to determine the forensic sex using pelvic X-rays on a sample of Libyan Population in Tripoli. Subjects and methods: The study includes 156 persons (15-25 years) in two groups; Group I which includes 78 Males. Group II which includes 78 females). All subjects will be subjected to poster anterior pelvis X-rays to determine sex estimation by: the height of ilium, interacetabular distance, acetabular diameter, pelvic breadth and pelvic inlet breadth. Results: In comparison between male and female in different measured parameters, there was a statistical significance increase in the height of ilium and acetabular diameter in male and in inter-acetabular distance and breadth of pelvic inlet among females; but no statistical significance difference found between male and female in greatest breadth of pelvis. Conclusion: The pelvis bone is good for sex determinations with the maximum percentage of 86% sex estimation accuracy. It is reliable tool in estimation of forensic sex estimation.
