Throughout history, fractures have been treated by immobilization, traction, and internal fixation. Construction of a stabilization system composed of bone plate and screws combination depends on factors such as type of fracture, biomechanical behavior of stabilization system, and surgical preference. In this study, the influence of plate design, material properties, and screw placement was investigated through the use of Experimental Design and Finite Element simulation. A three dimensional model of the ulna bone was reconstructed from computer tomography images and a simple oblique fracture was simulated. The fracture was stabilized in different modes, using combinations of three different design plates with the material properties of stainless steel and titanium alloy fixed with three, four, and six screws. The biomechanical behavior was compared in terms of equivalent stress and total deformation. Results showed that the fixation mode and plate design have the largest influence on the biomechanical behavior of the bone-plate assembly.
