ABSTRACT
The determination of variables such as age, height, ethnicity and sex are extremely important to the identification of biological findings, especially in accidents with fatal victims. The diagnosis of sex can be 100 % certain for cases in which the skeleton is complete and in a good state of conservation, the individual is an adult and the morphometric variables of the population to which the individual belongs are known. The aim of the present study was to perform a morphometric evaluation of the proximal femur and compare measurements between males and females. Sixty pairs of femurs were acquired from the Department of Animal Morphology and Physiology of the Universidade Federal Rural de Pernambuco. The bones were measured with the aid of the ImageJ software program and the following variables were compared between bones from male and female cadavers DFH - diameter of femoral head on the craniocaudal and sagittal axes; DFN - diameter of femoral neck on the craniocaudal and sagittal axes; FNL - femoral neck length; ILL - intertrochanteric line length. The morphometric variables had the following mean values in the male bones DFH-craniocaudal axis - 45.10 ± 0.35 mm; DFH-sagittal axis - 48.27 ± 0.35 mm; DFN-craniocaudal axis - 33.21 ± 0.40 mm; DFN-sagittal axis - 29.96 ± 0.05 mm; FNL - 31.71 ± 0.05 mm; ILL - 66.47 ± 0.59 mm. The mean values for the female bones were as follows DFH-craniocaudal axis - 40.68 ± 0.20 mm; DFH-sagittal axis - 42.61 ± 0.20 mm; DFN-craniocaudal axis - 29.11 ± 0.03 mm; DFN-sagittal axis - 26.05 ± 0.04 mm; FNL - 31.10 ± 0.04 mm; ILL - 60.80 ± 0.41 mm. With the exception of the femur neck length, all variables measurements were significantly larger (p < 0.0001) on the male bones. The present findings demonstrate that the femur bone, particularly the proximal portion, exhibits important sexual dimorphism and has high potential for forensic purposes.
RESUMEN
La determinación de variables como la edad, la altura, el origen étnico y el sexo son extremadamente importantes para la identificación de los hallazgos biológicos, especialmente en accidentes con víctimas fatales. El diagnóstico de sexo puede entregar una coincidencia del 100 % para los casos en los que el esqueleto está completo y en un buen estado de conservación, el individuo es un adulto y se conocen las variables morfométricas de la población a la que pertenece el individuo. El objetivo del presente estudio consistió en realizar una evaluación morfométrica del fémur proximal y comparar las mediciones entre hombres y mujeres. Se adquirieron sesenta pares de fémures del Departamento de Morfología y Fisiología Animal de la Universidade Federal Rural de Pernambuco. Los huesos se midieron con la ayuda del programa de software ImageJ y se compararon las siguientes variables entre los huesos de cadáveres masculinos y femeninos DCF diámetro de la cabeza femoral en los ejes craneocaudal y sagital; DCF diámetro del cuello femoral en los ejes craneocaudal y sagital; LCF - longitud del cuello femoral; LLI - longitud de línea intertrocantérea. Las variables morfométricas tenían los siguientes valores medios en los huesos masculinos Eje craniocaudal DCF - 45,10 ±0,35 mm; DCF-eje sagital - 48,27±0,35 mm; DCF-eje craneocaudal - 33,21 ± 0,40 mm; DFN-eje sagital - 29,96 ± 0,05 mm; LCF - 31,71 ± 0,05 mm; LLI - 66,47 ± 0,59 mm. Los valores medios para los huesos femeninos fueron los siguientes DCFeje craneocaudal - 40,68 ± 0,20 mm; DCF-eje sagital - 42,61 ± 0,20 mm; DCF-eje craneocaudal - 29,11 ± 0,03 mm; DCF-eje sagital - 26,05 ± 0,04 mm; LCF - 31,10 ± 0,04 mm; LLI - 60,80 ± 0,41 mm. Con la excepción de la longitud del cuello del fémur, todas las medidas variables fueron significativamente más grandes (p <0,0001) en los huesos masculinos. Los presentes hallazgos demuestran que el hueso del fémur, particularmente la porción proximal, exhibe un importante dimorfismo sexual y tiene un alto potencial para fines forenses.
