Umgangatho oPhezulu we-Titanium iyonke yoMfakelo woTshintsho oluHlangeneyo lwedolo
I-Knee Implants ye-Titanium Iimpawu
Umgangatho ophezulu wokufakelwa kwamadolo e-titanium edibeneyo
Ukufakelwa kwedolokwaziwa njengeidolo ilungu lokwenziwa kwamalungu, zizixhobo zonyango ezisetyenziselwa ukutshintsha amadolo awonakele okanye anesifo. Ngokuqhelekileyo zisetyenziselwa ukuphatha izigulane ezine-arthritis enzima, ukulimala, okanye ezinye iimeko ezibangela intlungu engapheliyo yamadolo kunye nokuhamba okulinganiselweyo. Injongo ephambili yokufakelwa kwamadolo adibeneyo kukunciphisa intlungu, ukubuyisela umsebenzi, kunye nokuphucula umgangatho wobomi bonke kwizigulane ezinobunzima obukhulu bedolo.
Icandelo lobufazi le-aidolo joint replacementyintsimbi okanye iqhekeza le-ceramic elithatha indawo yokuphela kwethanga (femur) kwindawo edibeneyo yedolo. Inemilo elinganisa i-anatomy yendalo yethambo ukuyinceda ukuba ingene ngokukhuselekileyo kwilungu. Icandelo le-femoral lixhomekeke kwithambo ngesamente ekhethekileyo okanye ngokusebenzisa i-press-fit technique ekhuthaza ukukhula kwamathambo malunga nokufakelwa.
Ngexesha leidolo joint replacementutyando, ugqirha uya kwenza i-incision edolweni kwaye asuse inxalenye eyonakalisiweyo ye-femur. Ugqirha wotyando uya kuthi ke alungise ithambo ukuze lifumane ukufakelwa kwelungu lobufazi. Icandelo le-femoral liya kubekwa kwaye likhuselwe endaweni ngokusebenzisa i-samente yethambo okanye ubuchule bokucofa. Emva kokuba icandelo le-femal likhona, ugqirha uya kuvala i-incision kwaye isigulane siya kuqalisa inkqubo yokubuyisela. Ukulandela utyando, izigulana ziya kufuna ukuthatha inxaxheba kuqeqesho lonyango lomzimba ukunceda ukuqinisa idolo kunye nokukhuthaza ukuphilisa. Emva kweenyanga ezimbalwa zokuvuselela, izigulane zinokulindela ukuba idolo lizive lingcono kakhulu kwaye liphucule ukusebenza. Nangona kunjalo, kubalulekile ukulandela nayiphi na imiyalelo emva kokusebenza enikezelwe ngugqirha wotyando ukuqinisekisa ukuphilisa kunye nokubuyisela.
Kuphephe ukuxhomekeka kwizinto ezintathu
1.Uyilo lweradiyasi ezininzi lubonelelas inkululeko yokuguquguquka kunye nokujikeleza.
I-2.Uyilo lwe-radius ehlayo ye-J curve femoral condyles inokuthwala indawo yoqhagamshelwano ngexesha lokunyuka okuphezulu kwaye ugweme ukufaka ukukhutshwa.
Uyilo oluthambileyo lwe-POST-CAM lufezekisa i-osteotomy encinci ye-intercondylar ye-PS prosthesis. Ibhulorho yamathambo eqhubekayo yangaphambili inciphisa umngcipheko wokuphuka.
Uyilo olufanelekileyo lwe-trochlear groove
I patellatrajectory eqhelekileyo yi S shape.
● Thintela i-patella medial bias ngexesha lokujika okuphezulu, xa idolo elihlangeneyo kunye ne-patella zithwala amandla okucheba kakhulu.
● Musa ukuvumela ipatella trajectory cross line line.
1.Iiweji ezinokuqhagamshelwa
2.Udonga lwecala lwe-intercondylar olukhazimlisiweyo luthintela ukukrazula kwesithuba.
3.Ibhokisi ye-intercondylar evulekileyo ithintela ukukrazula kwe-post top.
I-Flexion 155 degree ingabayimpumelelongobuchule obulungileyo botyando kunye nomthambo osebenzayo
Iicones zoshicilelo ze-3D ukuzalisa iziphene ezinkulu ze-metaphyseal ngesinyithi esinemingxuma ukuvumela ukungena.
I-Knee Joint Replacement Izalathisi
Irheumatoid arthritis
I-post-traumatic arthritis, i-osteoarthritis okanye isifo samathambo
I-osteotomies ehlulekile okanye ukutshintshwa kwe-unicompartmental okanye ukutshintshwa kwedolo elipheleleyo
