Originální abstrakt
Possibility of substituting the affected hip joint with endoprothesis is for many people all over the world the only way for returning to the normal life without pains and significant motion limitations. But the age limit requiring the application of replacement becomes lower and lower. The endoprothesis applied to young patients must be replaced several times during their lives and the application and repeated replacements affect the bone so that it may happen that the next application may not be possible any more. For such cases the surface replacement the purpose of which is to postpone the need of the first application of the classic total endoprothesis, has been invented. So that the objective of the contribution consists in creating a computing model of the healthy hip joint and the hip joint with the classic total hip replacement and with the surface replacement, in carrying out the stress-strain analyses, and in mutually confronting the results obtained. The problem has been solved as a direct task by means of computational modelling, by the method of finite elements in the ANSYS. The computational model consists of these components: sacral, pelvic and femoral bone, muscles, cup, and femoral component.
Český abstrakt
V současné době dochází k velmi intenzivnímu rozvoji povrchových náhrad kyčelního kloubu. Povrchové náhrady typu kov-na-kov byly navrženy jako alternativa k totálním náhradám kyčelního kloubu pro mladé a pohybově aktivnější pacianty. Cílem tohoto příspěvku bylo vykonat deformačně-napěťovou analýzu kyčelního kloubu s aplikovanou povrchovou náhradou.
