Investigation for the Effects of Newly Designed Hip Prosthesis on Crack Propagation Using Probabilistic Methodology

Abstract

In orthopedic prosthesis design, finite element method is one of the commonly used mathematical methods for performing structural analyzes and reducing test costs before it is applied to the patient. Surgeons and engineers should work together to design reliable durable and hip replacement. Desirable functional requirements for prosthesis design include high fatigue life, small relative displacement between the prosthesis-cement interface, and reduced stress on the bone and prosthesis. For this purpose, the progression of the fracture was calculated by applying the scenario of the presence of crack in the bone cement of the designed prosthesis using optimization methodology. The same conditions were analyzed in commercially available Charnley type prosthesis and the results were compared. When the obtained results are examined, it is seen that the newly designed prosthesis is more effective than the Charnley type prosthesis.
