Study of Greater Sciatic Notch in Sex Determination of Hip Bone by Metric Method

Abstract

Identification of sex of an unknown individual from the skeletal remains is the first and the most important step encountered by the forensic experts and archiologists. The hip bone is considered as an ideal bone for sex determination as it provides the highest accuracy levels. Many workers have studied various metric parameters for sexing of hip bone. The present study was done with an aim to find out the sex of hip bone using various parameters of greater sciatic notch. For this purpose, 100 dry hip bones were collected from the Department of Anatomy, VIMS, Bellary. Seven different parameters of the greater sciatic notch were used for the study: Maximum width, Maximum depth, Posterior segment, Index I, Index II, Total angle and Posterior angle. All the parameters (especially posterior segment, posterior angle and index II) were found to be highly indicative of sex hip bone by t-test (p<0.005) except the depth.
