Popis: Sex identification is an important step toward establishing identity from unknown human remains. The study was performed to test accuracy of sex identification using digital radiography of proximal epiphysis of femur among known cross-sectional population at Suez Canal region. Seventy-two radiographs of femur of living non-pathologic individuals were included. Original sample was divided into two equal groups of females and males (24 each). Test sample (group 3) included 24 radiographs. Six landmarks (A–F) were selected and 15 distances were generated representing all possible combinations of these landmarks. A is a point on the shaft under lower end of lesser trochanter, B is a point on the shaft. A–B is perpendicular to the axis of the shaft. C and D are points on femoral neck. E and F are points on femoral head. In original sample, mean and standard deviation were calculated, then accuracy, sensitivity and specificity. In test sample, the 15 distances were used to identify sex of that radiograph according to the cut-off value made from original sample. In original sample, CE and EF were most distinctive measurements for sexual dimorphism. AB and CF showed least accuracy (66.7% and 70.8%). BF, CE and EF were most sensitive for identification. In test sample, CE and EF showed 100% accuracy. AB and CF showed least accuracy (54.2% and 62.5%). AC, AE, BC, BE, BF, CE and EF were most sensitive for identification. Digital radiography of femur can be an alternative measurement used in sex identification in Egyptian population.
