Abstract

In the case of femur bone fracture, internal fixation is usually applied for the treatment due to the convenience and amenities of follow-up care. Due to a high demand for internal fixation implants in Indonesia, causing Pelopor Teknologi Implantindo Inc. (PTI Inc., Mojokerto-Indonesia) produces conventional implant material made from annealed local raw material of 316L stainless steel, with a yield strength of 317 MPa and ultimate tensile strength of 580 MPa. Compared to implant material in ASTM F138, it has a higher value of both yield and ultimate tensile strength. To determine the effects of material type, normal stresses will be used to evaluate the fractured bone, while von Mises stresses will be used to analyze the strength of fixation plate. Besides, influence of material variation to the bone healing process is also discussed. Transversal-type fracture is chosen for fracture modeling of femoral shaft. The loading is taken from body weight of Asians, which is applied at femur head. The simulation result indicates that in the case of conventional fixation plate, there is no significant influence on the bone healing caused by different material type.
