Abstract: One hundred and twenty-seven pairs of tibias of Chinese were measured. They were collected from Changchun and Tongliao Districts, Liaoning Province. Twenty-six measurements including the length, width, circumferece, diameter and angle were measured and four indices were calculated. The results show that most measurements have no statistic difference between two sides, but the sex-difference of all the measurements are highly significant (P<0.01). The data were analysed by using Fisher's method. Five discriminant formulae for sex determination with accuracy test on the same series of tibias produced correct results in 78.3% to 82.3% of cases.
