Abstract

This Research Study analyze the Biomechanical performance (Stress Strain and Displacement) Fixation Plates used for fixing the Femur Fracture. The Femur Anatomy and Fixation Plates were designed in CAD tool and further Biomechanical performance were analyzed using Comsol Multiphysics. In simulation Femur distal end kept Fixed and Applied load on femoral head to analyze the walking condition of human body. Results Finalized that overall deformation of Femur and Fracture plate was very low which means that the system was stable and can hold fractured bone properly. However the highest stress and strain were observed near the fracture region and at screw bone area because of greater portion of applied load concentrated here. Among all the materials (Stainless steel and Cobalt) which were analyzed Titanium is the one which shows best biomechanical performance because it provide good balance between Stiffness and stability. The appropriate material selection and using Finite element analysis made the stress Distribution to the bone plate easy. This study help to reduce Stress Shielding and ensure the successful healing of the fractured bone. It recommends the use of mechanically stable materials such as titanium alloys along with FEM-assisted pre-surgical planning.
