Sexual Dimorphism in the Femoral Head—A new Approach

ABSTRACT This paper presents a new method for metrically defining sexual dimorphism in the human femur. It presents a standardized technique for establishing anatomically meaningful landmarks for measuring vertical and horizontal diameters of the femoral head, based on weight transmission. The study was conducted at the Medicolegal Institute of Bhopal, India, on a sample comprising of 124 individuals (80 males and 44 females), the majority of them being medicolegal specimens. The mean age was 58.3 years for males and 52.4 years for females. To check the efficacy of the newly suggested method, the bones were also measured for maximum vertical and horizontal diameters following traditional anthropometric techniques. The method based on “non-conventional” measures was found to be more accurate (94.7% for vertical and 95.2% for horizontal diameter) as compared to the traditional techniques. Intra- and inter-observer statistics are also presented.
