Inkcazelo emfutshane:

Ufakelo lwe-X4 edolweni lusetyenziselwa ukuphelisa izikhalazo zesigulana malunga namalungu amadolo angasebenziyo okanye ngokwemilinganiselo, ngaphandle kwezigulana ezinomgangatho wobomi obuhlayo obubangelwa ziintlungu ezinxulumene ne-arthrosis.Iiprostheses ezidibeneyo zedolo ziquka ezi nxalenye zilandelayo;amacandelo femoral, ufakelo, amacandelo tibial, iziqu, izikhonkwane, amandongomane, amacandelo patellar.

Iinkcukacha zeMveliso

Iithegi zeMveliso

I-condyle yangaphambili yeprosthesis ye-femoral ibonelelwa ngobubanzi obuncitshisiweyo kunye nobukhulu ukunciphisa uxinzelelo lwangaphambili lwe-condyloid kunye ne-quadriceps tension.I-geometry ye-sagittal efanayo kunye ne-curvature egudileyo ivumela i-patella ukuba inganyusi amandla e-quadriceps femoris xa idolo lilula kwaye liguquguquka.Ngokudibanisa ne-patellar trochlear groove enzulu, inokuqinisekiswa ukuba i-patella izinzile kwaye kwi-groove nakwi-flexion ephezulu ngaphandle kokuphazamiseka, kunye nokudibanisa okuzinzileyo phakathi kwe-patella kunye ne-femoral prosthesis kugcinwa ngamaxesha onke.

I-prosthesis ye-femoral iyilwe kunye nenqwelomoya egobile kancinane ukunyusa indawo yoqhagamshelwano ukuze kuncitshiswe uxinzelelo oluphezulu kwi-polyethylene efakwe.I-point-to-point edge bearing ikhutshwa ngexesha lokujikeleza kwe-varus-valgus emadolweni, ukwenzela ukuba i-tibiofemoral joint ihlale igcina ukujongana nobuso.

I-patellar notch yangaphambili ye-polyethylene ifaka inciphisa uxinzelelo olongezelelweyo kunye noxinzelelo kwi-quadriceps femoris ngexesha lokunyuka okuphezulu.

I-condylar curvature yangasemva iyanda.I-tibiofemoral articular surface ihlala idibene nomphezulu kunokuba i-point contact xa i-flexion ifikelela kwi-135 degrees.

Vula i-intercondylar fossa design: I-osteotomy ye-intercondylar iyancitshiswa, kwaye ithambo ligcinwe kwinqanaba elikhulu kwisigulane.

Ukulungelelaniswa kwesakhiwo se-cam-post: Ikhamera isagcinwa kwisiseko sekholomu ngelixa idolo liphezulu, likhusela ukwenzeka kokukhutshwa komlomo wesibeleko ngexesha lokunyuka okuphezulu kwinqanaba elincinci.

Kunikiwe isixhobo sokutshixa esisodwa.Ukulungiswa kwesibini kunye nee-anchors zetsimbi kunokuphelisa ukugqoka okukhathazayo phakathi kwezi zibini.

Isakhiwo se-tri-wing sithintela ukujikeleza kwaye sigweme ukuxinzelela uxinzelelo.
