Abstract
Background: There are some relatively definite indications for fixing these problems which can be as the surgery with Osteotomy and the deformation and making the bone fixed in new location. There are so many techniques in this field with respect to the surgery and the kind of osteotomy, and with respect to the kind and fixation tool.Genovalgum is usually a disorder in femur distal and this point can be repaired by osteotomy. From the past, the blade plate is an attractive option for the fixation which can be harder than newer methods like lockable blade-plates for the younger surgeons. In this research, our goal was to present a new design of blade plate for more easiness in tool installation and test the finite element for making sure of the effectiveness of the new tool. The goal of this research is to design a modular sample of blade plate and the biomechanical comparison of these two states in the finite element form. In this research, the biomechanical behavior of these two methods with pseudo-static loading on the made model in the finite element software. Methods: The CT-Scan images were transformed to Mimics software. Then, the model under biomechanical analysis was placed in abaqus19.0 software in pseudo-static form. The bone was considered as orthotropic and stainless-steel implant. Results: In the comparison of the tension of blade plate and bone, the tension on the blade-plate and bone has been reduced in modular blade plate which is possibly related to the energy waste in the connection of blade and plate. The strain of modular blade plate is significantly less than the older blade plates, but the strain of the bone without orthosis is much more similar to the previous blade plate with respect to the strain of the bone
