Abstract :

INTRODUCTION:–

The sex determination of the skeletons is of most importance to the physical and the forensic anthropologist’s .Sex determination is an important issue of anthropological and forensic sciences. Determination of sex is a priority issue for further analysis of unidentified ancient human remains, because all techniques of identification are markedly different for males and females. The tibia is an ideal long bone of the limb which is used for sex determination, as it resists the erosive forces which act and it remains unaffected even after the burial of the body.The present study provides sex determination using discriminant analysis from tibia measurements in Mumbai region.

Material and Methods:

100 human tibia of known sex (50 males and 50 females) were procured from the Department of Anatomy from various medical colleges of Mumbai.

RESULTS AND DISCUSSION:–

In our study, the length of the right and the left tibia of the males and females were measured. The length of the right male tibia ranged from 34.2 –46.8 cm with a mean of 40.5 cm whereas the length of the right female tibia ranged from 32.6–44.2 cm with a mean of 38.4 cm. Calculated t–value and P value Showed that the difference in the mean maximum length in male and female was highly statistically significant with P<0.001.

CONCLUSIONS–

From the present study, it was clear that certain parameters of the tibia could help in sex determination from fragments of the tibia also. The sexual dimorphism in the tibia is not only due to the general growth and the musculoskeletal activity, but also due to the genetic structure of the population.
