Sexing Of Human Clavicles Of North Karnataka Zone By Measuring Their Mid-shaft Circumference

ABSTRACT

The sex determination of the individual is primary criterion of identification in Forensic anthropology but this isvery difficult problems & becomes even more challenging when only a single bone like clavicle is available. Thecorrect determination of the sex of a dead person is a critical requirement in physical anthropology. Within pastfew years, the physical anthropologists have become increasingly involved in the problems of humanidentification. The traditional methods of sexing bone are subjective and not of much help where 100% accuracyof sexing is required. For the metrical analysis of sexing of clavicle by the present study method, mid-shaftcircumference of 155 adult human clavicles of known sexes were measured with the help of measuring tape, stripof graph paper and Vernier Calipers. The mid-shaft circumference of right side male clavicles ranges from 30mmto 46mm (mean of 37.14 ± 4.10mm), where as that of female clavicles ranges from 25.5mm to 41.5mm (mean of30.50 ± 3.3mm). The mid-shaft circumference of left male clavicles ranges from 30mm to 48mm (mean of 37.04±4.2mm) where as that of female clavicles ranges from 24.5mm to 39.5mm (mean of 30.3±3.3mm). The mid-shaftcircumference of clavicles has a high significance in sex determination (P<0.001). The prediction of correct sexby mid-shaft circumference of clavicles alone is 77% for male & 83.30% for female right clavicles & 80% for ofmale & 87.50% for female left clavicles.
