Introduction: The identification of sex in human skeleton is important for many anthropologists, anatomists and forensic experts. Pelvis remains the most reliable region for assessing sex. Sacrum, as a part of pelvis also demonstrates differences. The most useful aspect of such studies is to determine appropriate standards of parameters for sexual dimorphism in different populations. Hence this study was undertaken to evaluate the role of different parameters of sacrum in sex determination. Materials and Methods: Study was carried out in Department of Anatomy, BVDU Medical College, Pune. Adult, dry sacra were collected randomly from Anatomy department of different Medical colleges of Maharashtra, with the kind permission of the concerned authorities.141 sacra were classified in to male and female bones by observing parameters like length of sacrum, width of sacrum, transverse diameter of body of S1, anteroposterior diameter of S1, length of ala of sacrum. Results: As a part of univariate analysis, demarcating point (D.P.) was obtained for each of the parameter. The % of bones identified beyond D.P. was found for each of them. The accuracy of this method varied from parameter to parameter. Ventral straight length of sacrum, mid-ventral curved length, anteroposterior and transverse diameter of body of S1 were more in male than female sacra with statistically significant difference in them. Whereas values for the parameters like sacral width (breadth) and length of ala of sacrum were more in female than male sacra with statistically significant difference. Conclusion: For different populations based on geographic areas different anthropometric criteria should be applied which could be specific to that particular population. It can be concluded that to identify the sex of sacrum with 100 % accuracy, single parameter was not sufficient instead it requires multiple parameters and indices to reach at the most accurate result.
