Abstract

The present research was designed to derive a model to determine sex from digital measurement of adult clavicle. The following discriminant function was obtained:

DF = 0.61 (Right Clavicle Length) + 5.40 (Right Mid Shaft Diameter) – 14.05

Overall 90.0 % of the cases could be correctly classified in to the two sexes from the two predictors [in the model]. Cross-validated results showed correct classification in 88.3% cases. At the individual group level, 86.2% of males and 93.5 % of female were correctly classified. Sexing of the adult human clavicle is thus possible with reasonably acceptable accuracy using the age specific discriminant function on a sample obtained from the Indian Bengali population. This investigation help postulate that the clavicle undergoes morphometric and morphological remodeling with aging even after completion of ossification.
