Simulation here confirms the assumption that shape parameters are naturally optimal within a given nonpathological forearm. We here present a preliminary quantitative approach to analysing how 3D shapes match in order to better evaluate how such a coupling impacts on a functional motion. Addressing long bone morphometry, we study the influence of the 3D shape of forearm bone structures on the limitation of rotational range during pronation-supination motion. On the basis of modelling at successive stages –shape, deformation, then motion–, simulation here confirms the assumption that shape parameters are naturally optimal within a given nonpathological forearm. While the need to focus on shaft regions is supported as regards this particular bone-joint subsystem, it is finally advised that the restriction to only bones should give way to including the interosseous ligament into a higher order of modelling.
