Numerical analysis for a distal radio fracture fixation plate using the Finite Element Method

A plate for internal fixation of distal radius fractures is presented. A stre sses numerical evaluation under different loads is made. The finite element method, through the ANSYS V.11 program, has been used. The implant geometry was modeled to generate a complete system with the plate, bone and screws. The contour conditions were applied using external forces on osseous segment. Stresses concentrations near hole of plate, extremes screws and interface bone-plate are shown. In general, the plate stresses was under elastic r ange.
