Resumen : In the framework of the armed conflict, forced disappearance in the country and in Antioquia, which occupies the first place, has contributed to the increase of unidentified bodies found mainly in graves. In this regard, estimating the sex of the human skeleton is basic in rebuilding the biological profile of the unknown individual. Due to the lack of local methods, forensic researchers use international methods for human identification; A slow and difficult process due to the population variability expressed in the specific shape and size characteristics of each individual that change throughout the life cycle. Due to the above and bearing in mind that the humerus is one of the bones most conserved from the taphonomic effects, this study sought to establish the multivariate indicators of size and shape that more accurately estimate the sexual dimorphism in the humerus. In the reference collection of the laboratory of Anthropological Osteology of the University of Antioquia, measurements of the humerus were taken. With the discriminant statistical model of step inclusion, we selected the best measures for sex discrimination, we obtained centroids or cut-off points. We generated the constant, the coefficients and the classification rates for each measurement and the general classification rates. 91.3% of the individuals were correctly classified, while the cross-validation was 90.7%. This means that the model has great significance and predictive ability, therefore it can be used for the estimation of sexual dimorphism in humerus.
