Sexing based on measurements of the femoral head parameters on pelvic radiographs

Abstract Background and aim Previous studies have shown that the collo-diaphysial angle varies by race and sex in different populations. This study was performed to compare the femoral head parameters in the two sexes using pelvic radiography in Iranian adults during the August 2011 to August 2012 period. Materials and methods This cross-sectional study was done on 100 male and 100 female. After taking hip radiography, collo-diaphysial angle, maximum femoral head diameters and minimum femoral neck width were measured on both sides. Dominant hand, height, weight and body mass index were also recorded. Data were analyzed using SPSS software. Sex differences were tested using independent t -test and ROC curve. Results The mean of the right and left maximum femoral head diameters and the minimum width of the femoral neck were significantly higher in men than in women ( p
