Abstract
Introduction: There are many features in humans which exhibit sexual dimorphism. A unique feature showing this gender differentiation is the ratio of lengths of index and ring fingers. Sexual dimorphism in finger lengths has been studied across the globe, wherein ethnic and racial variations in digit ratio have been reported. Our studywas conducted in the central Indian population, where no such study was done till now. Aim: To study the prevalence of sexual dimorphism in central Indian population using ratio of phalangeal and metacarpal length of index and ring fingers.

The lengths of phalanges and metacarpals of index and ring fingers were measured on X rays films and their ratios were taken and analyzed statistically.
