I-Orthopedic titanium knee joint prosthesis
I-Orthopedic titanium knee joint prosthesis
Idolo liyilunga elikhulu kunawo wonke emzimbeni womuntu. Ixhuma i-femur yakho ku-tibia yakho. Kukusiza ukuthi ume, unyakaze futhi ugcine ibhalansi yakho. Idolo lakho libuye libe ne-cartilage, njenge-meniscus, nemigqa, kuhlanganise ne-anterior cruciate ligament, i-middle cruciate ligament, i-anterior cruciate ligament, kanye ne-anterior cruciate ligament.
Kungani sidingaukushintshwa kwamadolo ahlangene?
Isizathu esivame kakhuluukuhlinzwa esikhundleni samadoloukuqeda ubuhlungu obubangelwa isifo sokuqaqamba kwamalunga. Abantu abadinga ukuhlinzwa okufakwe amadolo banenkinga yokuhamba, ukugibela izitebhisi nokusukuma ezihlalweni. Umgomo we-knee replacement prosthesis ukulungisa ubuso bendawo eyonakele emadolweni nokunciphisa ubuhlungu bamadolo obungakwazi ukulawulwa ezinye izindlela zokwelapha. Uma ingxenye yedolo yonakele, udokotela ohlinzayo ngokuvamile angashintsha leyo ngxenye. Lokhu kubizwa ngokuthi i-partial knee replacement. Uma lonke ilunga lidinga ukushintshwa, ukuphela kwethambo le-femur kanye ne-tibia kuzodinga ukubunjwa kabusha, futhi lonke ukujoyina kuzodinga ukuvela. Lokhu kubizwaukushintshwa kwamadolo okuphelele (TKA). I-femur bone kanye ne-tibia amashubhu aqinile anesikhungo esithambile ngaphakathi. Ukuphela kwengxenye yokwenziwa ifakwa engxenyeni emaphakathi yethambo.
Gwema i-pendency ngezici ezintathu
1.I-multi-radius design inikeza
s inkululeko yokuguquguquka nokujikeleza.
2.Umklamo werediyasi eyehlayo ye-J curve femoral condyles ingathwala indawo yokuxhumana phakathi nokuguquguquka okuphezulu futhi igweme ukufaka umgodi.
Idizayini ethambile ye-POST-CAM ifinyelela i-osteotomy encane ye-intercondylar ye-PS prosthesis. Ibhuloho lethambo eliqhubekayo elingaphambili eligciniwe linciphisa ingozi yokuphuka.
Idizayini ye-trochlear groove efanelekile
I-patellatrajectory evamile iyisimo sika-S.
● Vimbela ukuchema kwe-patella medial ngesikhathi sokugoba okuphezulu, lapho idolo elihlangene kanye ne-patella kunamandla okugunda kakhulu.
● Ungavumeli i-patella trajectory cross center line.
1.Amaweji aqhathanisekayo
2.Udonga oluseceleni olupholisheke kakhulu lwe-intercondylar lugwema ukuhuzuka kokuthunyelwe.
3.Ibhokisi elivulekile le-intercondylar ligwema ukuhuzuka kwe-post top.
I-Flexion 155 degree ingabaokuzuziwengesu elihle lokuhlinza nokuzivocavoca okusebenzayo
Izigaxa zokuphrinta ze-3D zokugcwalisa amaphutha amakhulu e-metaphyseal ngensimbi enezimbotshana ukuvumela ukungena.
Izinkomba Zokushintshwa Kwamalungu Edolo
I-Rheumatoid arthritis
I-post-traumatic arthritis, i-osteoarthritis noma isifo samathambo esiwohlozayo
Ama-osteotomies ahlulekile noma ukushintshwa kwe-unicompartmental noma ukushintshwa kwamadolo okuphelele
idolo lokufakelwa Imininingwane
