Biomechanical Analysis of Femoral Fixation with a New Compression Plate Using Finite Element Method during Stair Climbing

Article Preview

Abstract:

LC-DCP (limited contact—dynamic compression plate) is the preferred plate in internal fixation. A new LC-DCP fixed with the femur was designed. Its strength was investigated with finite element method during stair climbing. Also, stress shielding and strength of femur fixed with TC4 (Ti6Al4V) compression plate was analyzed for different load mode during stair climbing. Simulated results demonstrated that compression plate’s design was reasonable, and it was not obvious to eliminate femoral stress shielding through adding preload on the screws. Also the analytical methods of stress shielding for femur fracture, established in the work, can be widely applied to stress shielding analysis of other bone fracture.
