I-prosthesis yedolozizixhobo zonyango ezisetyenziswa kutyando lokutshintshwa kwedolo. Ngokusekelwe ekubeni i-posterior cruciate ligament igciniwe na, ii-primary total knee arthroplasty prostheses zahlulwe zibe zii-Cruciate Retention (CR) type kunye ne-Posterior Stabilized (PS).
Iprosthesis Yokugcina Imilenze Eqinileyo (CR Prosthesis)
Iboniswa kwizigulana ezinomsebenzi opheleleyo we-posterior cruciate ligament, ukukhubazeka okuncinci kwamalungu kunye ne-osteoporosis enzima.
Iprosthesis Ezinzileyo Yangasemva (PS Prosthesis)
Ifanelekile kwizigulana ezineengxaki zomsebenzi we-posterior cruciate ligament, ukukhubazeka okukhulu kwamalungu, i-osteoporosis okanye iziphene zamathambo.
Zithini izinto eziyinxalenye yei-prosthesis yamadoloNgokwesiqhelo yenziwe ngamacandelo amathathu.
Inxalenye yeFemoralIthatha indawo ye-articular cartilage yomphezulu wefemoral kwaye idla ngokwenziwa ngeesinyithi ezifana ne-cobalt-chromium alloy okanye i-titanium alloy.
Inxalenye yeTibialIthatha indawo yesakhiwo se-meniscus yomntu. Iqulathe ipleyiti yesinyithi kunye ne-polyethylene liner ukubonelela ngenkxaso ethwala ubunzima.
I-Tibial Baseplate ithatha indawo ye-articular cartilage yomphezulu we-tibial kwaye idla ngokwenziwa nge-titanium alloy.
Kutheni sifunaukutshintshwa kwedolo?
Eyona sizathu siqhelekileyo sotyando lokutshintshwa kwedolo kukunciphisa iintlungu ezibangelwa yi-arthritis. Abantu abafuna utyando lokutshintshwa kwedolo banengxaki yokuhamba, ukunyuka izinyuko kunye nokuvuka ezitulweni. Injongo yokufakelwa kwedolo kukulungisa umphezulu wendawo eyonakeleyo yedolo kunye nokunciphisa iintlungu zedolo ezingenakulawulwa zezinye iindlela zonyango. Ukuba yinxalenye yedolo yonzakeleyo kuphela, ugqirha otyandayo unokutshintsha loo nxalenye. Oku kubizwa ngokuba kukutshintshwa kwedolo elingaphelelanga. Ukuba lonke ilungu lifuna ukutshintshwa, isiphelo sethambo le-femur kunye ne-tibia kuya kufuneka sitshintshwe, kwaye lonke ilungu kuya kufuneka libe ngaphezulu. Oku kubizwa ngokuba kukutshintshwa kwedolo elipheleleyo (TKA). Ithambo le-femur kunye ne-tibia ziityhubhu eziqinileyo ezineziko elithambileyo ngaphakathi. Isiphelo senxalenye yokwenziwa sifakwa kwindawo ethambileyo ephakathi yethambo.
Isishwankathelo,oi-rhetopedicki-neeiizityalo ezifakelweyozisisombululo esibalulekileyo ekunyangeni izigulana ezinengxaki yokungasebenzi kakuhle kwamalungu edolo. Zibonelela izigulana ngendlela yokubuyisela ukuhamba kwazo nokuphucula umgangatho wobomi bazo, nto leyo ezenza zibe lukhetho olubalulekileyo kwicandelo lezonyango lwamathambo. Ngokuhambela phambili kwetekhnoloji, uyilo kunye nezixhobo zeayokwenyaniki-neeji-ointzihlala ziphucuka, kwaye kulindeleke ukuba oku kuzise iziphumo zonyango ezingcono kwizigulana kwixesha elizayo.
