Abstract

Sve veća životna dob stanovništva, način života, nepravilna ishrana, veća tjelesna težina i smanjena fizička aktivnost samo su neki od razloga koji dovode do učestalijih pojava artroze,smanjene pokretljivosti i povećanja boli zgloba kuka. Endoproteze predstavljaju kliničko rješenjekoje bi trebalo u odgovarajućoj mjeri otkloniti navedene pojave. S biomehaničkog stanovištaosnovni uvjet endoproteze je zadržati funkcionalnost kroz cijelo vrijeme eksploatacije.U ovom radu provedeno je dinamičko ispitivanje izdržljivosti endoproteze zgloba kuka uskladu sa normama ISO7206-1 do ISO7206-8. Odabrani su uzorci izrađeni od različitihmedicinskih materijala te dobiveni različitim tehnologijama izrade koje se danas koriste uproizvodnji endoproteza. Dobiveni rezultati osim same verifikacije proizvoda koristit će se i urazvoju novog proizvoda.

Abstract (english)

The increasing life time expectancy, life style, irregular diet, the increasing body masstogether with decreasing physical activity are some of the reasons that lead to frequent incurrenceof the arthrosis, reduced mobility and increasing paint in the hip joint region. Hip joint prosthesesare the clinical solution that should sufficiently overcome these problems. From thebiomechanical point of view hip joint prostheses should maintain life time functionality.In this paper dynamic determination of endurance properties of hip joint prostheses wascarried out according to the international standards ISO7206-1 - ISO7206-8. Specimens used inthe experiments were made from different medical materials and produced with differenttechnologies which are currently used in the hip joint prostheses production. Beside productverification, the obtain results will be used in new product developments.
