  • Abstract Information regarding the stresses and strains in the canine femur during various activities is important for veterinary orthopeadic surgeons, engineers designing implants for dogs. Finite element analysis has commomly been used to investigate the effect of stress distribution following hip replacement. Therefore, the objective of the current study is to reconstruct the three-dimensional solid model of GOLDEN RETRIEVER and investigate the biomechanical performance of a prosthesis(designed by Dr. Lin)by comparing the stress distributions with the intact canine femur. Assess this prosthesis and face the feasibility in clinic, is regarded as the reference of future operation or other academic research by this.
    An image-processing software(Armira)was used to process the sectional computed tomography images of a GOLDEN RETRIEVER femur and to reconstruct the solid model of the bone. Then the solid model of the bone was transferred to a CAD program(Soliworks)to simulate the implantation of a hip prosthesis. Finally, the finite element analysis was performed using a finite element package(Cosmos)with the proper setting of boundary and losding conditions.
     The results can be summarized as : the torsion and the bending moment was occurred on the femur and the peak effective stress was reached at the caudo-medial diaphysis. We found that the implanted femur has physiological stress distribution on the intact femur. Furthermore, as far as prosthesis be concerned the peak tensile stress occurred in the hole of the posterior diaphysis. Nevertheless, the prosthesis was not broken. It can provide immediate stabilization of the implant and the preservation of endosteal vascularity.
