Abstract :The femur is one of the most commonly recovered bones in mass casualty disasters and is often used for identification, both for height and gender. However, in most cases the femur cannot be obtained as a whole. Therefore, this study evaluated and compared the reliability of gender estimates based on measurements taken from the proximal and distal ends of the femur.The study was conducted by evaluating the measurements of 226 femurs on radiological images obtained from a total of 128 individuals (67 males and 61 females). All the radiological images were obtained from the archive of the Radiology Department of Başkent University Faculty of Medicine, Adana Application Research Center. Eleven of the anthropometric measurements were linear and two were angular.When the anthropometric measurements obtained from the whole sample were evaluated in terms of differences between the right and left sides, significant differences were observed between the sides in terms of intercondylar angle, intertrochanteric distance (bc), inclination angle (inc), and collum femoris width (b - b). On the other hand, as a result of statistical analyses performed to predict gender, significant differences were found between both sexes in all measurements except intercondylar angle and inclination angle. Logistic regression analysis was performed and a formula was developed to determine sex with the data obtained. ROC analysis was performed to determine a threshold for the discriminability of the measurements taken from the distal and proximal ends of the femur for gender prediction, and the variable that gave the best results was determined to be the inter-epicondylar distance.
