“…They concluded that the mean sacral index in females is higher than that of males in Indian populations. Somesh et al (2015) [17] also endorsed that the sacral index remains very useful indicator, though they suggested that other parameters, e g., sacral linear and curved lengths should also be included in sex determination. Shreekrishna et al (2013) [18] from Tamil Nadu sacra highlighted the importance of certain parameters like sacral index while also demonstrating insignificance other parameters, but basic fact remains that as far as the sex determination of sacrum is concerned no single parameter could identify sex in 100% of the bones and hence, it can be concluded that for sex determination of the sacrum with 100% accuracy is possible only when maximum number of parameters are taken into consideration.…”

Aim: To report the first ever made discovery of two 70,000 years-old prehistoric fossil sacra along with their detailed comparative morphometric study with modern human sacra to see any pattern of difference between the modern and prehistoric sacra.Methods: In all 22 parameters were used for the metric analysis of the two fossil sacra which include 17 linear and curved measurements and five indices, and six were used as sexing criteria. These were compared with those of the extant Indian populations. Results:The two fossil sacra show some morphological difference from the modern human sacra in having less posterior curvature, and squarer outline of the male and rectangular of the female sacrum. They also exhibit very distinct sexual dimorphism in sacral index, though metric variables are within modern human range. Conclusion:There are noticeable differences between the fossil sacra and typical modern human sacra, more so among the sexes indicating as if early humans were highly dimorphic sexually since ca.70-80 kya.

Background: Sacral Index is the most important parameter in assessing the sexual dimorphism. Materials and Methods: A total of 42 dry adult human sacral bones of known sex (19 -female sacra; 23male sacra) collected from Anatomy Department, Santhiram Medical College, Nandyal. The sacral length measured from the promontory to the middle of antero-inferior margin of last sacral vertebra. The sacral breadth measured from the lateral most points of ale of sacrum. The sacral index (SI) is calculated and statistically analyzed. Results: We noted the mean sacral index 101.142+2.148 in male sacra, and 103.668+2.271 in female sacra with significantly higher sacral index in female sacra than male sacra in the present study. Conclusion:Our study acknowledges the importance of sacral index and its significance can be useful in sexual dimorphism.
