MODAL ANALYSIS OF FEMUR BONE TO FIND OUT THE SUITABLE BIO COMPOSITE BONE IMPLANT MATERIALS

The materials selected for the bone implants are most important and while selecting the materials care must be taken like biocompatibility, cost and feasibility and so on. Three different materials viz natural bone, PMMA/HaP, Nylon 6/HaP, and Poly-lactic acid/HaP are selected for the modal analysis. A three-dimension model of the femur bone is prepared from the CT scan image using ITK-SNAP code. MSC- Patran-2017 is used as a pre and post processor and Nastran-2017 as the solver. From this analysis, we found that the probable fracture of bone occurs near the femoral head and knee joint, but the modal frequency of any of these materials is not exceeding natural fumer bone frequiency. PMMA/HaP is best suited for bone implants because its modal frequencies are optimal and also it had an optimum weight in comparison with Nylon 6/HaP, and Poly-lactic acid/HaP composite materials.
