Se desarrollaron 14 funciones discriminantes para los metacarpos, con porcentajes del 79,5% a 85,3% de asignación sexual correcta, siendo el segundo metacarpo el hueso más dimórfico de la muestra.
Empleando un vernier digital se tomaron 5 medidas (longitud máxima y 4 anchuras) en cada uno de los huesos del metacarpo y del metatarso. Se analizaron métricamente los metacarpos y metatarsos de 112 esqueletos adultos contemporáneos (49 femeninos y 63 masculinos) de la Colección-UNAM del Laboratorio de Antropología Física, Facultad de Medicina, UNAM.
Therefore, it can be used in forensic contexts for human identification with complete or fragmented remains, in the cases where no other bone element is available, such as the pelvis.Įl objetivo de este estudio fue la obtención de funciones discriminantes para estimación del sexo a partir de mediciones directas en metacarpos y metatarsos para contribuir en la identificación de individuos desconocidos. The discriminant functions of metacarpal and metatarsal bones obtained are generally above 80%, which is similar to reports from other populations. In general terms, the widths of both epiphyses were the most dimorphic measurements. In this case the first metatarsal was the most dimorphic. For metatarsals, five discriminant functions were obtained, ranging from 77.8% to 83.2% of certainty. The second metacarpal was the most dimorphic of the sample. Resultsįourteen discriminant functions were developed for metacarpals with percentages from 79.5% to 85.3% of correct gender classification. Five measurements were taken (maximum length and four widths) of each metacarpal and metatarsal bones employing a digital calliper. The sample belongs to the Autonomous University of Mexico (UNAM) Collection from the Physical Anthropology Laboratory, UNAM Faculty of Medicine. Material and methodsĪn analysis was performed on metacarpal and metatarsals bones of 112 adult contemporary skeletons (49 females and 63 males). The aim of this study was to obtain discriminant functions for estimating gender from direct measurements of the metacarpal and metatarsal bones for identification of unknown individuals.
