Abstract:

Biomechanics is the application of mechanical principles on the living organisms and utilizing the principles of physics, simulation and study of biomechanical structures are carried out. Finite Element Method is one of the widely accepted tools for modeling the biomechanical structures. The femur is the only bone located within the human thigh. It is both the longest and the strongest bone in the human body, extending from the hip to the knee. The method most surgeons use for treating femoral shaft fractures is intramedullary nailing. During this procedure, a specially designed nailing is inserted into the marrow canal of the femur. The rod passes across the fracture to keep it in position. An intramedullary nail can be inserted into the canal either at the hip or the knee through a small incision. It is screwed to the bone at both ends. This keeps the nail and the bone in proper position during healing. The Femur bone is modelled using 3-D Scanner and analysis is carried out in an ANSYS environment. The fracture fixation nailing is modelled using the commercially available Solidworks CAD software. The stress distribution at the fractured site of the femur is obtained when the system is subjected to compressive loadings along with healing stages. The effects of the use of different biomaterials for the nailing on the stress distribution characteristics are also investigated. Intramedullary nails are usually made of titanium. They come in various lengths and diameters to fit most femur bones. But the titanium is very costly metal. Hence the cost of surgery is more. Therefore aim to find best alternative metal in low cost.
