Abstract		Background. Total hip replacement is a good solution for the patients with hip arthrosis. Aseptic loosening is the major long-term problem which is manifested with pain, especially with weight bearing. Interface between bone ad implant is of crucial importance for the developing of aseptic loosening. Due to forces and pressures acting on the cement mantle, micromovements and frank fissures develop, leading to the development of soft tissue interface membrane. Due to citochemical factors acting in the interface chronic inflamation and finally osteolysis and loosening issue. Conclusions. In the article historical backroung of total hip replacement and mechanical and biological factors in relation to aseptic loosening are presented.
Summary		Izhodišča. Vstavitev umetnega kolka je dobra rešitev za bolnike z artrozo kolka. Največji dolgoročni problem predstavlja aseptično omajanje, ki se sprva kaže z rentgenskimi znaki, kasneje pa postane tudi klinično manifestno z bolečino, zlasti pri obremenjevanju. Stik med kostjo in vsadkom je bistvenega pomena za nastanek omajanja. Zaradi delovanja sil in tlakov se pojavijo premiki in celo poke v cementnem plašču, na stiku pa nastane vezivna membrana, kjer zaradi delovanja citokemičnih dejavnikov pride do kroničnega vnetja in posledično do osteolize in omajanja. Zaključki. V članku je opisan zgodovinski razvoj umetnega kolka ter osnovni mehanični in biološki dejavniki, povezani z omajanjem.
