“…However it can't be said if any particular sternum given is definitely male or female by these rules. 2,9 The sternal index of female was significantly greater than the male in our study. However few authors found no significant difference between the SI of two sexes as both of the values were close and above fifty.…”

“…1,7,19 Though, a number of bones such as pelvis, skull, femur etc., have contributed significantly in estimating sex, 2,7,10,20 in situations when these bones are missing, less sexually dimorphic bones as sternum should be taken. 2,7,9,14,15,[21][22][23][24] The sternum having a robust structure can survive a great degree of compression and can be procured from cadavers without damage. 1,2,5,10,13,18 Many researchers have studied sternum in order to prove its usage as an indicator of sex in different populations.…”

“…5,7 Since the bones resist putrefaction and destruction by animals, they are cardinal clue for identification.

Introduction: The comprehensive goal in forensic anthropology is the identification of skeletal remains for which researchers are constantly working to produce methods that are as accurate as possible. Because of distinct sexual dimorphism, bones of the pelvis and skull are preferred; however, when these bones are unavailable other bones like sternum have to be used as it holds a great deal of sexual dimorphism. Objective: To evaluate sexual dimorphism in the metric parameters of the sternum through MDCT images amongst Nepalese adults. Materials and Methods: Sternal dimensions of 105 study participants (62 male and 43 female) were measured using Computed Tomography (CT) images from Radiology Department of Dhulikhel Hospital. An independent t test was performed to assess the strength of association between different variables and genders. Differences were considered significant at P < 0.05. ROC curve analysis was done to determine the discriminating power of variables for sex determination. Result: The different measurements of sternal lengths were significantly greater in male than females(p<0.001) except Sternal Index which was found to be higher in female (p<0.001). Despite this difference in mean, most of the sterna were in overlapping zone. The limiting point of 126 was determined for total sternum which could correctly classify majority of sternum. Using ROC curve the mesosternum and total sternum were found to be most accurate (>95%) in sex determination. Hyrtl’s law could classify 91.9% of the male and Ashley’s rule of 136 could 97.67% of the female. Conclusion: Hence this study made an effort in sexing the sternum in Nepalese population amongst which mesosternal length and total sterna length were found to be best estimators of sex whereas manubrium length and sternal index were not found to be satisfactory.

“…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.…”

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.
