Sex Determination from Lower End of Humerus Using Morphological Traits in Indian Population

Abstract

One of the main objective in forensic examination is identification. In case of skeletal remains examination
sex determination is one of the important parameter for identification. Here in this study lower end of
humerus is studied for sex determination by morphological method. As there is difference in carrying angle
between male and female, there also should be observable difference existing in lower end of humerus.
Hence four morphological characteristic features of distal humerus including shape of olecranon fossa, angle
of medial epicondyle, trochlear symmetry and trochlear constriction were assessed for sexual dimorphism
and their accuracy in sex determination. When each of these features considered individually the result was,
shape of olecranon fossa showed more accuracy (m:87%, f:69%) in sex determination and if any three of
these features considered collectively accuracy in sex determination was (m:61%, f:72%).
