Prothèse yo gusimbuza ikibuno imara igihe kingana iki?

Hip arthroplasty ni uburyo bwiza bwo kubaga uburyo bwo kuvura umutwe wa femorale femorale, osteoarthritis yo mu kibuno, hamwe no kuvunika kwafemoraleijosi mu zabukuru.Hip arthroplasty ubu nuburyo bukuze bugenda bwamamara buhoro buhoro kandi burashobora kurangizwa no mubitaro bimwe na bimwe byo mucyaro.Hamwe n'ubwiyongere bw'umubare w'abarwayi basimbuza ikibuno, abarwayi bakunze guhangayikishwa n'igihe prothèse izamara nyuma yo kubagwa gusimbuza ikibuno niba bizaramba ubuzima bwabo bwose.Mubyukuri, igihe cyo gusimbuza ikibuno gishobora gukoreshwa nyuma yo kubagwa biterwa nibintu bitatu byingenzi: 1, guhitamo ibikoresho: kuri ubu hari ibikoresho bitatu byingenzi bifatanyiriza hamwe: head ceramic head + igikombe ceramic: igiciro kizaba gito muremure.Inyungu nyamukuru yuruvange ni uko usanga irwanya kwambara.Muri ceramic na ceramic friction, umutwaro umwe, kwambara no kurira ugereranije nicyuma ni ntoya cyane, kandi uduce duto dusigaye mumyanya ihuriweho kubera kwambara no kurira nabyo ni bito cyane, mubyukuri ntihazabaho reaction yo kwangwa kumubiri kwambara ibice.Ariko, mugihe cyibikorwa bikomeye cyangwa igihagararo kidakwiye, harikibazo gito cyane cyo guturika ceramic.Hariho kandi abarwayi bake cyane bahura nijwi rya "creaking" ryatewe no guterana ceramic mugihe cyibikorwa.

HeadMetal head + polyethylene igikombe: amateka yo gusaba ni maremare kandi ni menshi cyane.Ibyuma kuri ultra-high polymer polyethylene, mubisanzwe ntabwo bigaragara mubikorwa bifite urusaku rudasanzwe, kandi ntibizacika nibindi.Ariko, ugereranije na ceramic na ceramic friction interface, yambara ugereranije gato munsi yumutwaro umwe mugihe kimwe.Kandi mu mubare muto cyane w'abarwayi bumva neza, bizakira imyanda ishaje, bitume gutwika imyanda yo kwambara bibaho mubisubizo, kandi buhoro buhoro ububabare bukikije prostate, kurekura prothèse, nibindi. Kuri interineti yo guteranya ibyuma (cobalt-chromium alloy, rimwe na rimwe ibyuma bitagira umwanda) Iyi interineti yo guteranya yakoreshejwe mu myaka ya za 1960.Nyamara, iyi interface irashobora kubyara umubare munini wibyuma byambara, ibyo bice birashobora kuba fagocytose na macrophage, bikabyara umubiri wamahanga, kwambara ibyuma byakozwe na ion bishobora no kwinjira mumaraso, bigatera allergie reaction mumubiri.Mumyaka yashize, ubu bwoko bwimikorere ya interineti bwahagaritswe.Head Umutwe wa Ceramic kuri polyethylene: Imitwe yubutaka irakomeye kuruta ibyuma kandi nibikoresho byatewe cyane.Ceramic ikoreshwa muri ubu buryo bwo kubaga gusimburana hamwe ifite ubuso bukomeye, budashobora kwihanganira, bworoshye cyane bushobora kugabanya cyane igipimo cyo kwambara cya interineti ya polyethylene.Igipimo cyo kwambara cyatewe ni munsi yicyuma kuri polyethylene, mu yandi magambo, ceramic to polyethylene nuburyo bwo kwambara birwanya kwambara kuruta ibyuma kuri polyethylene!Kubwibyo, ikibuno cyiza cyibihimbano cyiza, gusa mubijyanye nibikoresho, ni ceramic-to-ceramic interface ihuriweho.Impamvu yubuzima burebure bwigihe kinini cyuru rugingo ni uko igipimo cyo kwambara kigabanywa inshuro icumi kugeza ku magana ugereranije n’ingingo zabanjirije iyi, bikongerera cyane igihe cyo gukoresha hamwe, kandi ibice byambara ni imyunyu ngugu ihuza abantu idakora. bitera osteolysis na osteoporose hafi ya prothèse, ikwiriye cyane kubarwayi bakiri bato bafite ibikorwa byinshi.2. Gushyira neza prothèse yibibuno: binyuze mugushira neza kwa prothèse mugihe cyo kubagwa, acetabulum nigiti cyigitsina gore Gukosora neza kwa prothèse hamwe nu mfuruka ibereye bituma prothèse idashyirwa hamwe kandi ikimurwa, bityo ntibitera kurekura prothèse.

Kurinda ikibuno cyabo: kugabanya uburemere, ibikorwa bikomeye (nko kuzamuka no gutwara ibiro birebire, nibindi) kugirango ugabanye kwangirika kwa prothèse.Byongeye kandi, irinde gukomeretsa, kubera ko ihahamuka rishobora gutera kuvunika hafi ya prothèse yo mu kibuno, bishobora gutuma prothèse irekura.

Kubwibyo, prothèse yibibuno ikozwe mubikoresho bidakabije, gushyira neza nezaikibunokandi uburinzi bukenewe bwikibuno gishobora gutuma prothèse imara igihe kirekire, ndetse no mubuzima.
