ABSTRACT:

Introduction: Sex determination of a skeleton remains is very important to the anatomists, anthropologists as well as forensic experts. The innominate has long been recognized as one of the most reliable skeletal indicators of sex in adult human beings. Three common parameters used by Derry (chilotic line index), Washburn (ischiopubic index) and Schulter Ellis (acetabulum pubic index) claimed to identify sex in high percentage of hip bones. Jit and singh (1966) suggested use of Demarking points (DP) to identify sex of the bone to highest accuracy. Present study was done to study sexual dimorphism in Ischiopubic index of hip bone and to study accuracy of Demarking Points of ischiopubic index in identifying a bone of a particular sex.

Materials and Methods: In present study, total numbers of 111 adult human hip bones 79 male and 32 female in department of Anatomy, M. P. Shah Govt. Medical College, Jamnagar, Gujarat were selected, their pubic length and ischial length were measured; Ischiopubic index calculated; DP for ischiopubic index determined.

Results: There was statistically significant difference in Ischiopubic index of male and female hip bones which was in accordance with previous studies. Also DP of present study was different from other studies.

Conclusion: Ischiopubic index differs from population to population and region to region  in same population; also DP method has certain limitations in sex determination. Therefore present study points towards a need for proper standardization of Mean Ishciopubic index as well as Demarking Point method for individual population, race etc for better identification of male and female hip bones.

Key words: Ischiopubic index, Demarking points, Sexual dimorphism.
