“…16 In contrary, osteometric measurement require a specific tool for measurement, but is simple, reliable and decreases the problem of observer's subjectivity. 7,10,16,19,27 On the other hand, metric method is also subjected to greater intraand inter-population variability. 16,19 Various metric studies have been applied using dry bones, X-rays and CT-scan image by various workers around the world.…”

“…The identification points (IP) were determined by the lowest value of a parameter in females and highest value for the same in males. 7,[23][24][25][26] All the values less than the minimum value for the females were treated as male bone for width, posterior segment, total angle, posterior angle and Index II and the bones having values more than maximum value of males were treated as female bones as females have greater measurement than male for these parameters. Similarly for Index I and depth, maximum value of female was IP for male and minimum value of male was IP for female as males have greater measurement than female in these parameters.…”

“…Early detection of disputed sex of an unknown individual is an important aspect of forensic investigation.

Background Sex identification from the skeletal remains, is the first and the foremost step encountered by forensic experts. Hip bone being comparatively robust is resistant to damage and scores even in improperly preserved skeletons. It is also widely agreed that the greater sciatic notch (GSN) holds the greatest degree of sexual dimorphism. Objective To study the role of greater Sciatic Notch parameters in sex determination among Nepalese population by means of reconstructed Multi Slice Three-Dimensional Computed Tomography (MDCT) images. Method The CT images of individuals who underwent pelvic CT in the Department of Radiology, Dhulikhel Hospital were included in the study. Measurements of width, depth, angles and indices of greater sciatic notch were measured and calculated. Data were entered and analyzed using SPSS (Statistical Package for Social Sciences) version 25.0. Result There was a significant difference between means of all greater sciatic notch parameters (p > 0.001) between sex showing sexual dimorphism except depth (p=0.65). By using limiting point, 78.18% male and 83.64% female were correctly classified by using total width. Total angle, Posterior segment and Total width had sensitivity and specificity exceeding 80% and overall accuracy of 87% to 92% in all parameters except depth by receiver-operator characteristic curve analysis. Conclusion Application of 3D-CT virtual images in the present study helped us to easily quantify greater sciatic notch parameters. The important greater sciatic notch predictors for sex determination in Nepalese population were determined which would help forensic experts in ascertaining the sex of an unknown individual.

The accurate observations and measurable investigations to identify the sex is the intrinsic step in biological profile development of the sample. In such scenario, sacrum identifies unknown sex and associated sex related functional differences more precisely. In the past, studies have shown that the morphological features of the sacrum are influenced by the sex hormone secretion and its associated reproductive functions. There are several parameters that can be considered when the sacral dimorphism is considered. Along with the sacrum measurements, the subpubic angle of the individual can also be measured. Among all the parameters used, the breadth and curvature of the sacrum were reliable indicators of sex among these measures. Additionally, it was also reported that none of the criteria could completely determine the sex of the bones. Therefore, it can be said that in order to determine the sex of the sacrum with 100 percent accuracy, consideration of all the parameters should be done. Further, other factors associated with the environment, physical stress, and genetic factors also affects this measurement. Hence, a groundwork about the previous research, is required while evaluating the sexual dimorphism in sacrum.
