[Computer stimulation of stress distribution in finite element models of the normal femur and after Weller, Centrament, Parhofer-Mönch type prosthesis implantation].
The paper presents an example of application of computerized analysis in the evaluation of the biomechanical reactions of the bone tissue after total hip replacement. Finite element models of the normal femur and femurs after Weller, Centrament and Parchofer-Monch type hip prosthesis implantation were constructed. Basing on these models, a comparative analysis of the stress patterns in all femurs was performed according to Pauwels' method. This study showed that total hip replacement leads to a redistribution and diminution of stress in the bone tissue, because of material disconformity of the prosthesis. The authors believe that the evolving virtual analytic tools used in simulations will in the future play a major role in reconstructive surgery.
