Abstract

Background: A primary aim of forensic medicine is gender determination. Although hip is the optimal bone for this purpose, different determining criteria of this bone do not have the same accuracy. This is important in conditions that only parts of hip remain to determine gender. This study aimed to evaluate the accuracy of different hip criteria in gender determination.

Methods: This cross-sectional study evaluated a total of 160 paired hips (80 males and 80 females) removed from the bodies for bone transplantation. Morphometric criteria were vertical and horizontal acetabular diameters and superior and inferior pubic ramus widths. Morphological criteria were a greater sciatic notch, obturator foramen, pubic body, preauricular sulcus, acetabular fossa position, and ischial tuberosity. The obtained data were analyzed using Cross Tab, t-test, and logistic regression analysis by SPSS. The significance level was set at P<0.05.

Results: There was no significant difference in morphometric and morphological criteria between the studied left and right hip bones (P>0.05). In gender determination, acetabular diameter and greater sciatic notch had the highest accuracy (85%), and obturator foramen (67.5%) and superior and inferior pubic ramus widths (65%) had the lowest accuracy.

Conclusion: Hip bone is not always completely available and preserved to determine gender. Moreover, sometimes not all anthropometric criteria of the bone are in favor of one gender. Therefore, investigating the accuracy of different criteria can be very important in interpreting the results. Thus, it has always been emphasized on the use of all available information in gender determination.
