Abstract
Introduction: The hip bone is an ideal bone for sex determination because it reflects the general differences between the two sexes and it also shows a special adaptation of female hip bone for childbearing. For sexing of human skeleton opinion of the experts regards the hip bone as providing the highest accuracy levels. Traditional non-metric methods such as visual examination of bone morphology for determination of sex, depends entirely on the ability and experience of an expert. It is almost impossible to assign sex with 100% certainty in all cases unless the whole skeleton is available.
The purpose of Study: The present study is done to determine the sexual dimorphism of human hip bone with respect to chilotic line and chilotic index (CI).
Materials and Methods: In the present study about 50 dry adult human hip bones of unknown sex are studied, the sex of the bones were determined by some non-metrical parameters, about 31 were classified as male and 19 were classified as females. From these two groups, the bones were further studied for metrical parameters which involved measurement of the pelvic segment and the sacral segment of the chilotic line, and the CI was also calculated.
Results: From the present study, it is revealed that the pelvic segment of the chilotic line is greater in females than in male hip bones and vice versa. The mean value of CI in males is found to be 117.86 and that in female hip bones is found to be 79.88. From the present study, it is also seen that the bones having CI < 85 are classified as female hip bones and bones having CI > 105 are classified as male hip bones.
Conclusion: From this study, it is concluded that the total chilotic line in males is longer than in females.
