Biomechanical Analysis of Selected Endoprostheses of Hip Joint by Means of Finite Element Methods

Abstract:

The main purpose of this paper was biomechanical analysis of hip joint endoprosthesis – femur systems by means of the Finite Element Method. During the analysis two endoprostheses with differential geometric features were selected. Geometric models of analysed implants were compiled on the grounds of real models like Merotan and The DePuy Proxima which were chosen from series diamensional. Afterwards the models were discretization and boundary conditions were set. Those boundary conditions with right accuracy copied a phenomena which occurred in real models - the Pauwels model. The field of analysis involved determination of the state of displacements, strains and stresses which were cut down in the of endoprosthesis – bone systems. The analysis that was carried out constitute the basics for optimisation of implant geometry and right selection of material’s mechanical properties to its production.
