Materials and Methods Finite Element Models.
The material properties for cannulated screw model, cancellous and cortical bones were appointed as homogenous, isotropic and linear elastic materials.
The stainless steel was chosen as material of cannulated screw thus the Young’s modulus of cannulated screw was assigned to 193 GPa.
