I-prosthesis yamadolokuyizinto zokwelapha ezisetshenziswa ekuhlinzeni esikhundleni sedolo. Ngokusekelwe ekutheni i-posterior cruciate ligament igciniwe yini, ama-primary total knee arthroplasty prostheses ahlukaniswa ngohlobo lwe-Cruciate Retention (CR) kanye nohlobo lwe-Posterior Stabilized (PS).
I-Cruciate Retention Prosthesis (i-CR Prosthesis)
Kuboniswa iziguli ezinomsebenzi ophelele we-posterior cruciate ligament, ukukhubazeka okuncane kwamalunga kanye ne-osteoporosis enzima.
I-Prosthesis Ezinzile Yangemuva (i-PS Prosthesis)
Ifanele iziguli ezinenkinga yokusebenza kahle kwe-posterior cruciate ligament, ukukhubazeka okukhulu kwamalunga, i-osteoporosis noma izinkinga zamathambo.
Yiziphi izingxenye ze-i-prosthesis yamalunga edoloNgokuvamile yakhiwe izingxenye ezintathu.
Ingxenye YesifazaneIthatha indawo ye-cartilage ehlanganisiwe ebusweni besifazane futhi ngokuvamile yenziwe ngezinsimbi ezifana ne-cobalt-chromium alloy noma i-titanium alloy.
Ingxenye Yesinqe Ithatha indawo yesakhiwo se-meniscus yomuntu. Yakhiwe nge-baseplate yensimbi kanye ne-polyethylene liner ukuze inikeze ukwesekwa okuthwala isisindo.
I-Tibial Baseplate ithatha indawo ye-articular cartilage ebusweni be-tibial futhi imvamisa yenziwe nge-titanium alloy.
Kungani sidingaukushintshwa kwejoyinti ledolo?
Isizathu esivame kakhulu sokuhlinzwa kokufakelwa idolo ukunciphisa ubuhlungu obubangelwa yi-arthritis. Abantu abadinga ukuhlinzwa kokufakelwa idolo banenkinga yokuhamba, ukukhuphuka izitebhisi nokuvuka ezihlalweni. Umgomo wokufakelwa kwedolo ukulungisa ubuso bendawo eyonakele yedolo nokunciphisa ubuhlungu bedolo obungenakulawulwa ngezinye izindlela zokwelapha. Uma ingxenye yedolo yonakele kuphela, udokotela ohlinzayo angayishintsha leyo ngxenye. Lokhu kubizwa ngokuthi ukushintshwa kwedolo okungaphelele. Uma lonke ilungu lidinga ukushintshwa, ukuphela kwethambo le-femur kanye ne-tibia kuzodingeka kushintshwe, futhi lonke ilungu kuzodingeka libe phezulu. Lokhu kubizwa ngokuthi ukushintshwa kwedolo okuphelele (TKA). Ithambo le-femur kanye ne-tibia kuyimibhobho eqinile enesikhungo esithambile ngaphakathi. Ukuphela kwengxenye yokwenziwa kufakwa engxenyeni ethambile ephakathi yethambo.
Ngokufigqiwe,oi-rthopedicki-neeiizimilaziyisisombululo esibalulekile sokwelapha iziguli ezinenkinga yokungasebenzi kahle kwamalunga edolo. Zinikeza iziguli indlela yokubuyisela ukuhamba kwazo nokuthuthukisa ikhwalithi yempilo yazo, okwenza zibe ukukhetha okubalulekile emkhakheni wezokwelapha ngamathambo. Ngokuthuthuka kobuchwepheshe, ukwakheka kanye nezinto zokwakhaaokwenziwayoki-neeji-ointziyathuthuka njalo, futhi kulindeleke ukuthi zilethe imiphumela yokwelashwa engcono ezigulini esikhathini esizayo.
Uma ufuna ukufunda kabanzi mayelana ne-ijoyinti yedolo le-titaniumulwazi, sicela ukhululekeXhumana nathi; ithimba lethu lizokunikeza ukwesekwa kochwepheshe kanye nezimpendulo.
