Iyo bigeze kubaga gusimbuza ikibuno ,.umutwe w'umugoreBya iikibunoni kimwe mu bintu byingenzi bigize ibice. Ifite uruhare runini mu kugarura umuvuduko no kugabanya ububabare ku barwayi bafite indwara zifata ikibuno nka osteoarthritis cyangwa necrosis avascular yo mumutwe wumugore.
Hariho ubwoko butandukanye bwibibuno bya prothèse femorale imitwe yo guhitamo, buri kimwe cyagenewe guhuza ibyifuzo byumurwayi hamwe nibitekerezo bya anatomique.Ibikoresho bikunze kugaragara ni ibyuma, ceramic na polyethylene.
Umutwe w'igitsina goreisanzwe ikozwe muri cobalt-chromium cyangwa titanium alloys kandi izwiho kuramba n'imbaraga. Mubisanzwe bikoreshwa mubarwayi bakiri bato, bakora cyane bakeneye igisubizo gikomeye gishobora kwihanganira urwego rwo hejuru rwibikorwa.
Umutwe wigitsina gore, kurundi ruhande, batoneshwa kubera igipimo gito cyo kwambarana biocompatibilité. Ntibakunze gutera allergie reaction, bigatuma bahitamo neza kubarwayi bafite sensibilité yicyuma. Byongeye kandi, ceramic femorale imitwe itanga ubuso bworoshye, kugabanya guterana no kwambara.
Polyethylene imitwe yumugorezisanzwe zikoreshwa zifatanije nicyuma cyangwa ceramic. Byaremewe gutanga umusego kandi muri rusange birahenze cyane. Ariko, ugereranije nibyuma cyangwa ceramic, birashobora gushira vuba, bigatuma bidakwiriye abarwayi bato kandi bakora cyane.
Muri make, guhitamo kwaikibunogufatanyaprothèse femorale umutweni ngombwa kugirango intsinzi yo kubaga ikibuno. Gusobanukirwa ubwoko butandukanye bwimitwe yumugore - ibyuma, ceramic, polyethylene, na hybrid - birashobora gufasha abarwayi nabashinzwe ubuzima gufata ibyemezo byuzuye ukurikije ibyo buri wese akeneye ndetse nubuzima bwabo.
