Background: Sex determination of unidentified skeletal remains from crime scenes or excavation sites is an important component in the development of the biological profile in forensics, anthropology and bioarchaeology. The purpose of this research is to determine whether sexing of unknown adult human humerus bones can be done by applying values of morphometric parameters and formulae generated by present study on adult human humerus bones of known sex and to find out the best parameters for sex determination.Methods: Various metric measurements were recorded using osteo metric board, measuring tape, non-elastic thread, sliding calipers and Vernier calipers on adult human humerus bones.Results: Sex was correctly estimated by using stepwise discriminant function analysis, for the clavicle 100% of males and 95% of females, with a total accuracy of 98.1%. Direct discriminant function analysis, correct estimated sex for the clavicle was 100% in males and 95% in females with a total accuracy of 98.1%.Conclusions: Present study exhibited better classification accuracy for multiple variables than those of single variables, the most discriminating variables in stepwise analysis are the weight, total length, transverse diameter of head, circumference of midshaft, trochlear width, capitulum width. In direct analysis, the single most useful variable was the transverse diameter of head.

“…1, 2 , Pablo Sebastián Giannotti 1, 2 , Horacio Chiavazza 3 y Gustavo Barrientos 1,4 Estimar el sexo a partir de huesos largos ha resultado de suma utilidad en muestras donde los indicadores clásicos, como la pelvis y el cráneo, se encuentran mal conservados, son fragmentarios o están ausentes (Black 1978;Mac Laughlin y Bruce 1985;Sakaue 2004;Šlaus 1997;Trancho et al 1997). Asimismo, en muestras procedentes de entierros secundarios u osarios, donde es necesario conocer el sexo de los huesos largos aislados para realizar reensamblajes de individuos (Byrd 2008), para hacer cálculos de número mínimo de individuos (Ubelaker 1974) y el número más probable de individuos (Adams y Konisberg 2004).…”

“…De esta manera, surge la necesidad de elaborar modelos regionales específicos en un intento de mejorar la exactitud en la determinación del sexo. Además, la mayoría de las muestras óseas empleadas para desarrollar criterios de estimación sexual a partir de huesos largos han sido obtenidas de poblaciones asignadas cronológicamente entre los siglos XV y XX y son principalmente de ancestría europea, africana o asiática (Asala 2001; Di Bennardo y Taylor 1982; King et al 1998;Mall et al 2000;Purkait y Chandra 2004;Sakaue 2004;Šlaus y Tomičić 2005). Si bien estos criterios podrían llegar a ser útiles en muestras de poblaciones históricas, en muchos casos tenemos el problema de no conocer la ancestría de los individuos analizados.…”

Páginas 00-00 Chungara, Revista de Antropología Chilena Los esqueletos incompletos y huesos humanos aislados constituyen un volumen importante del material recuperado en templos coloniales americanos. Esta situación lleva a la necesidad de realizar procedimientos que permitan la asignación sexual de cada elemento con el fin de profundizar diversos tipos de estudios bioantropológicos. El objetivo de este trabajo es desarrollar funciones discriminantes para estimar el sexo a partir de huesos largos en una muestra recuperada en tres templos coloniales de Mendoza (Argentina) correspondiente al período entre los siglos XVII y XIX. La muestra comprende 61 individuos adultos (entierros primarios completos), con sexo determinado a partir de indicadores pélvicos y craneanos. En cada caso, se tomaron un conjunto de medidas del húmero, radio, ulna, clavícula, tibia y fémur que fueron empleadas para generar funciones discriminantes. Las funciones desarrolladas permitieron estimar el sexo con un elevado porcentaje de asignaciones correctas, siendo el fémur (92,1%) y el húmero (90%) los elementos con porcentajes promedio de estimaciones correctas más altos y con porcentajes más elevados en el sexo masculino que en el femenino. La ulna (79,3%), la clavícula (79,2%), la tibia (75,9%) y el radio (73,3%) obtuvieron un poder de clasificación más bajo. Los resultados son discutidos considerando factores genéticos, ambientales y tafonómicos de la muestra estudiada.Palabras claves: estimación sexual, esqueleto postcraneal, poblaciones históricas, norte de Mendoza. Incomplete skeletons and commingled human bones constitute a significant volume of recovered material in American colonial temples. This poses the need to perform procedures that allow the sexual assignment of each element in order to deepen various types of bioanthropological studies. The objective of this work is to develop discriminant functions to estimate sex from long bones in a sample

“…Dimensions from the upper long bones (humerus, radius, ulna, and clavicle) have been used to successfully distinguish between the sexes in several European (Cowal and Pastor 2008;Bašić et al 2013;Kranioti and Tzanakis 2015), Asian (Sakaue 2004;Lee et al 2014) and African populations (Steyn and Işcan 1999;Barrier and Abbé 2008). In mentioned studies, different measurements have been shown to be good indicators of sex dimorphism.…”

Several studies have shown that sex estimation methods based on measurements of the skeleton are specific to populations. Metric traits of the upper long bones have been reported as reliable indicators of sex. This study was designed to determine whether the four long bones can be used for the sex estimation of an historical skeletal population from Radom (Poland). The material used consists of the bones of 169 adult individuals (including 103 males and 66 females) from the 18th and 19th centuries. Twelve measurements were recovered from clavicle, humerus, radius and ulna. The initial comparison of males and females indicated significant differences in all measurements (p < 0.0001). The accuracy of sex estimation ranged from 68% to 84%. The best predictor for sex estimation of all the measurements in Radom's population was the maximum length of the radius (84%), and the ulna (83%), and the vertical diameter of the humeral head (83%). The Generalized Linear Model (GLM) detected the strongest significant relationship between referential sex and the vertical diameter of the humeral head (p < 0.0001), followed by the maximal length of the ulna (p = 0.0117). In other measurements of the upper long bones, GLM did not detect statistically significant differences.
