Originální abstrakt
The presented work deals with the creation of computational model of total hip arthroplasty and the subsequent performance stress-strain analysis. The models of geometry of the pelvis and femur were created on base of CT data. In 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 prosthesis 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.
Český abstrakt
Předložená práce se zabývá tvorbou výpočtového modelu totální náhrady kyčelního kloubu a následné deformačně-napěťové analýzy. Tyto modely geometrie pánve a stehenní kosti byly vytvořeny na základě dat z CT. Výpočtový model obsahuje dřík totální endoprotézy tak i jamku. Na této soustavě byly simulovány skutečné podmínky zatížení. Chování celého soustavy je hodnocena na deformačně-napěťové analýzy.
