Background: Confirmation of the identity of an individual from fragmentary pieces of bones after considerable time lapsed since death is very crucial in medico legal cases. Hip bone is considered as one of the ideal bones for sex determination as it not only reflects the general differences between two sexes but also shows special adaptation of female hip bone for childbearing. Materials and Methods: 178 Adult hip bones (54 of females and 124 of males) of both sides were examined with special reference to chilotic line index, Ischiopubic index and Acetabulopubic index. All the hip bones were dry, free of damage or deformity and fully ossified. The personal record of all the hip bones for sex and race are all available with the bone bank (Govt Medical College Aurangabad).For all the six parameters and three indices, we measured range, mean, standard deviation, P value and demarcating points. All the observations were tabulated and analyzed statistically and compared with the previous studies. All the parameters and indices are statistically significant. Observations and Results: It was observed that when we applied univariate analysis only a few numbers of hip bones were correctly identified. Further we combined three indices in a single group and applied multivariate analysis. From our study it become very clear that very large number of hip bones can be identified correctly i.e. 85.5% of males and 83.3% females (mean 84%). Conclusion: Thus the sex of hip bones can be identified correctly in 84% cases by using these indices.
