Stress-Strain Analysis of Hip Joint after Application of Total Hip Arthroplasty with Consideration of Wear

Abstract:

The presented work deals with the creation of computational model of total hip arthroplasty and the subsequent performance of stress-strain analysis. The models of geometry of the pelvis and the femur were created on base of CT data. In To this model were fitted both of components, i.e. femoral stem and acetabular liner. On this system was subsequently modeled the real load conditions. Just real loading of the endoprosthesis leads to wear and it has great influence on the deterioration of bone tissue. These properties were simulated under the acetabular component. The behavior of the whole system is assessed on base of stress-strain analysis. From comparison the obtained results with clinical study it is evident that the places, that are dangerous in terms of establishment wear particles, are identical. This whole issue is very topical today.
