Determination of Bilateral Asymmetry of Clavicle in the Population of Vidarbha Region of Maharashtra

Anthropometric study of bones conveys information regarding race, sex, age and height of person. We conducted anthropometric study to know bilateral asymmetry in the clavicle of the population of Vidarbha region of Maharashtra.

The study consist of fully ossified clavicles belonging to the 60 dissection hall cadavers out of which 48 were males and 12 were females of known sex and stature collected from different medical colleges of the region. Measurements were taken with the help of Osteometric board, Vernier calliper and Spreading caliper. The length of each bone was measured in millimeters and the weight was taken in grams. Data was analyzed using "t" test by Microsoft excel software.

The length of right clavicle ranges from 108mm to 156mm with mean 137.78mm, SD 9.95, SEM 1.28 and coefficient of variation 7.22. On the left side the length varied from 108mm to 154mm with mean 138.76mm, SD 9.85, SEM 1.27 and coefficient of variation 7.09. The right clavicle is about 1mm smaller than the left clavicle (p > 0.05). The mean weight of right clavicle was 17.2gm while for left it was 17.09gms indicating that right clavicle is heavier than the left clavicle.

We conclude that the left clavicle is slightly longer than the right clavicle in both sexes and the right clavicles are heavier than the left clavicle in both sexes in the population of Vidarbha region of Maharashtra.
