ABSTRACT:

Background: Unfortunately, in the forensic context there are cases involving fetal and neonatal skeletal remains. Accurate sex estimation of these remains can be very important to medicolegal authorities. The present study was aimed to determine the sex of the fetal pelvis by the morphometric analysis of greater sciatic notch.

Materials and Methods: The study was carried out on 100 fetal hip bones extracted from 50 fetuses (25 female; 25 male). Morphometric analysis was carried out on the greater sciatic notch. The width and depth of the greater sciatic notch were recorded and the Index was calculated.

Results: Statistically significant difference was found between the female and male greater sciatic notches in relation to width, depth and index. Female greater sciatic notches were wider than the male and the male notches were deeper than the female. The greater sciatic notch index shows sexual dimorphism with 100% accuracy.

Conclusion: Accurate sex estimation of fetal remains can be very important to medicolegal authorities in forensic analysis. With the results of the present study the greater sciatic notch width, depth and the index can be taken as a best parameter in sex determination of fetal skeletal remains.

Key words: Greater sciatic notch, sex determination, Pelvis, Fetus, Sexual Dimorphism.
