Introduction: Identification is establishment of identity of a person with the help of different physical characteristics. The different physical characteristics of human skeleton between both the genders is the reason of Sexual dimorphism. Many researchers have studied and observed the different parameters for sexual dimorphismin different bones. Femur is an important bone which shows sexual dimorphism in different parameters. In modern era of advancement, pathological autopsy is shifting towards the virtual autopsy in which CT scan, MRI and X-rays are replacing the conventional autopsy instruments. From the femur bone, we took femur neck shaft angle for study.
Aims & Objective:To establish gender differentiation criteria in population of Bihar based on femoral neck shaft angle.
Materials and Methods:We used 200 antero-posterior view of pelvic along with femur bone digital radiograph, equal from both genders. Through digital radiograph of pelvic along with femur bone, we measured femur neck shaft angle with DICOM software. Results:Femur neck shaft angle in male and female gender was 127.51±9.18 and 124.68 ±7.25 respectively. Angle between shaft and head of femur for determination of gender was statistically significant.
Conclusion: males had significantly higher mean valve of femur neck shaft angle than female.
