Significance of weight for sexual dimorphism of talus bone

The present study aims to determine the sexual dimorphism of talus bone by using weight as a parameter. 100 pair of talus bones of known sex obtained from unknown or unclaimed cadavers brought to the mortuary for autopsy were included in the study. Weight of right talus and left talus of 50 males and 50 females was measured using an electronic weighing scale in this cross-sectional study. All the measurements in male talus were greater than the measurements in female talus bones. Univariate discriminant and logistic regression analyses were conducted on the data to estimate sex from the weight of the talus bone. The overall accuracy came out to be 89% in both sexes (84%-90% in males and 88% - 94% in females). In contrast to Identification and Demarcating points, Limiting point showed maximum classification accuracy in sex determination. Weight of talus bone thus showed statistically significant sexual dimorphism results and can be used to estimate sex along with other parameters
