Material and Methods: 60 adult sacra (30 male &30 female) were studied. Mean maximum sacral length and mean maximum sacral breadth were taken by sliding vernier caliper & sacral index was calculated. Data was statistically analyzed. Result: Mean maximum sacral length is significantly greater in males (113.5mm) than females (94.6). The difference between mean maximum sacral breadths is not significant. (Males-105.83 Females-104.33). Mean sacral index in females (110.63) is significantly greater than males (93.8). As per present study sacral index can reliably identify 53.33% of male sacrum and 46.67% of female sacrum. Conclusion: Sacral index is a reliable criterion for sex determination and is useful for anatomical, medico legal and anthropological purposes.
