Strain - Stress Analysis of Artificial Hip Joint, Influence of Bearing Material on Contact Pressure
Result description
Hip resurfacing surgery has been proposed as an alternative to THR for younger more active patients. The metal-on-metal hip resurfacing procedure involves fitting the femoral head with a metal surface and lining the acetabulum with a metal cup to form apair of metal bearings. Short-term clinical results persuade us to deal with FE analyses because it is important for development of the surface replacement prosthesis. The objective of this contribution is to perform finite-element analyses of computational model of the total surface replacement with different materials of bearing couples (acetabular cup/femoral head) and physiological hip joint. All results will be compared one another and then confronted with results of the physiological hip joint. The three-dimensional computational model consists of these components: sacral, pelvic and femoral bone, muscles, artificial socket, and surface hip replacement. The geometrical models of bones are generated by means of computed tomography

Deformačně - napěťová analýza uměleho kyčelního kloubu, vliv materiálu na kontaktní tlak
Czech description
Povrchová náhrada byla navržena jako alternativa k totální náhradě kyčelního kloubu. Je určena pro mladší a aktivní pacienty. Procedura nahrazení zahrnuje nahrazení hlavy femuru kovovou tenkostěnnou komponentou a acetabula kovovou jamkou. Cílem práce bylo vykonat deforormačně-napěťovou analýzu kyčelníhou kloubu s aplikovanou povrchovou náhradou pro různé kombinace materiálů jamka/femorální komponenta. Prostorový konečnoprvkový model obsahoval: pánevní, křížovou a stehenní kost, svaly, povrchovou náhradu. Geometrický model byl vytvořen z CT řezů. Uvažujeme stoj na jedné dolní končetině.
