Mathematical Standard-Parameters Dual Optimization for Metal Hip Arthroplasty Wear Modelling with Medical Physics Applications

Total hip metal arthroplasty (THA) constitutes an important proportion of the standard clinical implant usage in Medical Physics and Biomedical Engineering. A computational nonlinear optimization is performed with two commonly materials Metal-on-Metal (MoM) THA. Namely, Cast Co-Cr Alloy Titanium. The principal result numerical determination K adimensional-constant parameter model. Results from a new more powerful algorithm than previous contributions, show significant improvements. Numerical figures for dual give acceptable model-parameter values low residuals. These results are demonstrated 2D 3D Graphical/Interior Optimization also. According to findings/calculations, optimized metal-model parameters mathematically proven verified. Mathematical consequences obtained model improvements vitro simulation methodology. wear magnitude determinations these data constitute innovation method. In consequence, erosion prediction laboratory experimental testing THA adds valuable information literature. Applications lead medical physics material/metal-THA designs.
