The purpose for this work was to analyze the structural effects of the implantation of contemporary patellofemoral prosthesis on femur cancellous bone. In fact, studies on the state of strain/stress on patellofemoral arthroplasty are still very limited. The influence of the geometry and rigidity of the bone-implant interface is discussed, applying the Finite Element Method. One of the major reasons...
Aseptic loosening is the critical reason for the failure of the cemented total hip arthroplasty. It occurs due to bone remodeling triggered by stress shielding and cement mantle fracture. In this study, stress shielding and bone thickening phenomenon of the cemented THA femur was analysed using three dimensional finite element method for walking load case. The intact femur is modeled to consist of...
In this paper, a three-dimensional (3D) FE model of the healthy human axis was built considered cortical and cancellous bone. The model was validated using numerical results obtained by other authors. The stress distribution and potential fracture patterns of the anterior odontoid were analyzed under different loading direction within coronal plane and sagittal plane. The direction of loading is the...
