The aim of this study was to evaluate the biomechanical behavior of xenogenic bone plate system (equinebone) using a three-dimensional finite element ulna fracture model. The model was used to calculate the Von Misesstress (VMS) and stress distribution in fracture healing periods with metallic bone plate and xenogenic bone platesystems, which are installed while the canine patient is standing. Bone healing rate (BHR) (0%) and maximum VMSof the xenogenic plate was similar to the yield strength of equine bone (125 MPa). VMS at the ulna and fracturezones were higher with the xenogenic bone plate than with the metallic bone plate at BHRs of 0% and 1%. Stressdistributions in fracture zone were higher with the xenogenic bone plate than the metallic bone plate. This study resultsindicate that the xenogenic bone plate may be considered more beneficial for callus formation and bone healing thanthe metallic bon plate. Xeonogenic bone plate and screw applied in clinical treatment of canines may provide reducedstress shielding of fractures during healing.
