ABSTRACT
Objective: To do study the distance between Posterior superior Iliac Spine and Ischial tuberosity (PSIS-IT) of human hip bone for determination of sex. Methods: The study comprised unpaired 272adult human hip bones of known sex. The posterior superior iliac spine and ischial tuberosity were identified in all the hip bones and a slidingcaliper was used to measure the distance between them. Results: The raw data obtained was statistically analyzed. Range, mean, standard deviation and standard error of mean were determined for parameter. Conclusion: It was observed that out of 272 hip bones taken for study 160 were of males and 112 were of females. The Mean distance in males was observed to be greater in comparison to females. Statistically calculated t- test reveals that the parameter taken for study is very highly significant in terms of sex differentiation.
