ABSTRACT:

Aims and Objectives: To study the sexual dimorphism of dried human hip bone with respect to chilotic line and chilotic index (CI) and finding a cut off value for the chilotic index that will be accurate for identification of sex in the human hip bone.

Materials and Methods: The study was undertaken with a sample size of 44 adult human dried hip bones from the department of Anatomy GVP.I.H.C & MT, Visakhapatnam, Andhra Pradesh. The Chilotic line (sacral segment and pelvic segment) was measured using a Vernier calliper and chilotic index was calculated.

Results: The chilotic index in male hip bones fall in the range of 102.77mm-139.46mm with a mean value of 118.32mm and for females it lies in the range of 61.63mm – 98.17mm with a mean value of 84.84mm. This finding is statistically significant with p-value = <0.001.

Conclusion: The total chilotic line in males is longer than in females and a cut off value of 100.48 is statistically 100% correct in identification of a male and a female hip bone.

Key words: Chilotic Line, Chilotic Index, Ilium, Dimorphism, Sex Determination.
