Abstract

Prediction of sex from incomplete and decomposing skeletal remains is vital in establishing the 
identity of an unknown individual. The purpose of this study is to assess the applicability of external 
and medullary parameters of third and fourth metacarpals using multi-detector computed tomography
in sex determination in Egyptian population. All measurements showed significant sexual differences 
(P < 0.05). By simple discriminant analysis, mediolateral diameter of midshaft of the third metacarpal 
showed the highest percentage of accuracy (69%) in sex determination. This study concluded that 
metacarpals are useful bones for sex determination and also it imposes new forensic standards for 
determination of sex in Egyptian metacarpals using various discriminant equations.
