Cross section geometric (CSG) properties of the diaphysis of bones enable quantitative evaluations of bone functional adaptation. Several studies have previously analysed the effects of the division of labour, nutritional aspects, the ruggedness of the terrain, sexual dimorphism and of other factors affecting bone modelling and remodelling. The aim of this study is to evaluate the bone functional adaptation of the lower limbs through the analysis of the moments of inertia along the three axes x, y, z of bone cylindroids, and to compare the outcomes with the average values of the CSG properties (areas and second moments of area).
