Finite Element Analysis in Femoral Fixation with TA3 Titanium Compressioll Plate

Abstract

To analyze the stress shielding in femoral fixation with TA3 Titanium compressioll plate by using the finite element method. Firstly, establish TA3 Titanium compressioll plate, screws and three-dimensional geometric model of the femur; and its mesh, and the establishment of the corresponding three-dimensional finite element model; the final definition of material properties, and load boundary conditions. During standing state, the strength of plate and screw has been analyzed by the finite element method, while the femoral stress shielding has been analyzed. Standing stress when compared to normal bone stock, TA3 Titanium compressioll plate and screws for femoral stress shielding effect is not obvious. Established in this paper plate on the femur stress shielding of the analytical method can be widely applied in other state analysis of stress shielding bone fracture.
