CAIAFFO, V.; ALBUQUERQUE, P. P. F.; ALBUQUERQUE, P. V. & OLIVEIRA, B. D. R. Sexual diagnosis through morphometric evaluation of the proximal femur. Int. J. Morphol., 37(2):391-396, 2019. SUMMARY: 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; FNLfemoral 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.

Performance Evaluation of LIBSVM and MSVM in Human Age Estimation and Gender Identification from Digital Images of Femur bone

“…Authors have developed a model using an artificial neural network by collecting 100 individual femur samples from Coimbra Skeletal Collection. Vitor Caiaffo et al [11] conducted a survey study for comparison of male measurement and female measurements in the proximal femur part by collecting and examining 120 femur bones of 60 pairs, out of which 29 pairs of male gender and 31 pairs of females. The authors measured the bones by using software called ImageJ and they recorded the following variables for both males and females for comparison-Femoral head diameter (FHD), Femur Neck Diameter (FND), and Femoral Neck Length (FNL).…”

“…Las otras variables estudiadas, indican que las mujeres tienen fémures más pequeños que los hombres, tanto en su largo, como en el ancho epicondilar y el diámetro de la cabeza, por lo que el dimorfismo sexual sí estaría influyendo de manera significativa en el tamaño femoral. Esto también ha sido ampliamente documentado en otras poblaciones, e inclusive son variables que se utilizan para la creación de funciones discriminantes para determinar el sexo (Caiaffo et al 2019;Cavaignac et al 2016;Krenzer 2006).…”
