ABSTRACT

Aim: To find out similarities and differences in the metrical values of different sacral parameters in males and female and also to highlight the best parameters that could be used to study sexual dimorphism of sacrum. Material and methods: The average values of sacrum for ventral straight length was found to be 103.94±5.82 mm in male and 92.13±6.03 mm in female, maximum breadth was 102.31±4.26 mm in male and 103.21±6.37 mm in female and sacral index was 97.89±4.35 mm in male and 112.92±5.43 mm in female. The average values of first sacral vertebra for transverse diameter was 48.13±4.14 mm in male and 40.32±3.46 mm in female, antero-posterior diameter was 28.87±2.29 mm in male and 26.82±2.30 mm in female and index was 59.84±4.64 mm in male and 65.89±5.01 mm in female. Conclusion: Sacral index was found to be the best criterion for sex determination of sacrum using sacral index alone 28.31% of bones in males and 58.2% of bones in females could be identified. However not a single parameter could identify 100% of the bones.
