[Biomechanical studies of bone treated with intramedullary nailing, with special reference to possible axis deviations].

The effect of a misalignement of a nailed bone on the stress distribution in the cross section is shown theoretically. Also for pure axial loading of the bone a superposed bending due to the misalignement produces large tension stresses as well in the nail as in the bone, when the fracture is not healed. After healing the stresses in the nail and in the bone are reduced striking. The removing of the nail does not increase the stresses in the bone significantly.
