Abstract

Introduction: Human hip bone sexual dimorphism is an important parameter in determining gender of an unknown hipbone, an important point in Anatomy and Anthropology.

Aims & Objectives: To measure the Chilotic index of male and female dried hip bones in local population of Pakistan and determine a useful value to correctly identify male and female hip bones.

Place and duration of study: The study was conducted in the Department of Anatomy at University College of Medicine and Dentistry over a period of six months from October 2022 to Feb 2023.

Material & Methods: It was a descriptive cross-sectional study conducted on 44 (22 male and 22 female) dried hip bones gathered through stratified random sampling with 5% level of significance with desired power of 95%. Chilotic index was calculated after measuring sacral and pelvic parts of Chilotic line with vernier calliper. Data was analysed in SPSS 22, p value ? 0.05 was taken as significant.

Results: The range for the Chilotic Index for male hip bones was 81.92 to 124.91, with a mean and median of 102.08 &

103.75 respectively . On the other hand, the range for the Chilotic Index for female hip bones was 72.22 to 109.85, with a mean and median of 89.89 &87.19 respectively. The p value of 0.0023 and t value of 2.01 indicate that there is a significant difference between the Chilotic Index of male and female hip bones in the local population.

Conclusion: Overall, the results suggest that the Chilotic Index, as well as the pelvic and sacral segments of the Chilotic lines, are different between male and female hip bones. The cut off value of 95.98 statistically correct in identifying male and female hipbones in local population.
