| Abstract | This study investigated the influence of proximal radius fracture pattern on the biomechanical performance of lockingcompression plate (LCP) using the finite element method. Two transverse neck fracture levels and one oblique proximal radiusfracture, stabilized with stainless steel and titanium implants, were included in this study. The models of proximal radius andLCP implant set were created and virtually aligned using CAD. Four-node tetrahedral elements were used in the FE model.Articular contact pressures at the 0?, 45?, and 90? flexion angle of humeroradial ulna joint were applied to articular surface of theproximal radius. High stress concentrations were found between the proximal screws holes and around the combined holes ofLCP. Elastic strain at fracture gap stabilized with implant did not significantly differ between stainless steel and titaniumimplants. The stainless steel implant may present higher stresses than the titanium implant, especially with a fracture close to thearticular surface. |
