Introduction: In the identification of sex in human skeletal remains, sacrum is an important bone of the human skeletal system. Being a component of axial skeleton and because of its contribution to the pelvic girdle and in turn to the functional differences in the region between the sexes, it has an applied importance in determining the sex and related disorders with the help of measurements carried upon it. Therefore a study for sex determination was carried on 50 sacra, in the department of Anatomy Kasturba medical college, Manipal. India Materials and methods: The parameters used for the study were the different dimensions of the sacrum. Using the same the sacral index, auricular index were calculated. The morphology of the sacral hiatus and the extensions of the auricular surface were also studied. All the measurements were carried out using the digital vernier calliper. The readings were recorded and their mean and standard deviations were calculated. Results and conclusion: All the parameters chosen for the study were found to be reliable in sexing the sacra and identifying the related disorders.
