Anil Kumar, Nitin Vishwakarma

Abstract: Sacrum is a part of axial skeleton and has long been held as a bone which is highly sexually dimorphic. In the present study 43 dry human sacra were subjected to anthropometric analysis to study the gender difference. The measurements taken were tabulated and analyzed statistically. Sacral index, Curvature index, Corpobasal index and Index of first sacral vertebra were calculated. The results of present study were compared with previous studies. The sacral index was found to most useful parameter to establish the sexual identity of the bone. The values obtained in the present study can be a useful guideline for sex identification in cases of forensic investigations.
