After femoral shaft fractures, metal plates can be implanted to help its recovery. However, the main problem is that a bone fracture plate could crack or fail in the process of recovery, which cause a secondary damage to the patient. The stress concentration caused by the screw layout of the implanted plate is one of the main reasons for the fracture or failure. Since different screw layout solutions lead to different features of stress concentration, taking the femoral straight Ti alloy metal plate as the object, this research employed the optimization theory and the finite element analysis method to optimize the screw layout. Finally the optimal solution is obtained, which can improve fatigue strength of the fixation system and reduce the failure probability of the system, avoiding the secondary damage to the patient.
