Izimila Ezihlanganisiwe Zezinga Eliphezulu Le-Titanium Total Knee Replacement
I-Knee Implants Izici ze-Titanium
Izimila zekhwalithi eziphezulu ze-titanium ezihlanganisa idolo
Ukufakelwa kwamadoloobeye aziwe njengoi-prosthesis ehlangene yamadolo, ziyimishini yezokwelapha esetshenziselwa ukufaka esikhundleni samalunga amadolo awonakele noma anesifo. Zivame ukusetshenziselwa ukwelapha iziguli ezine-arthritis enzima, ukulimala, noma ezinye izimo ezibangela ubuhlungu obungapheli bamadolo nokuhamba okulinganiselwe. Inhloso eyinhloko yokufakelwa kwamadolo ahlangene ukukhulula ubuhlungu, ukubuyisela ukusebenza, nokuthuthukisa izinga lempilo yonke yeziguli ezinokukhubazeka okukhulu kwamadolo.
Ingxenye yesifazane ye-aukushintshwa kwamadolo ahlangeneucezu lwensimbi noma lwe-ceramic oluthatha indawo yokuphela kwethanga(i-femur) endaweni ehlangene yamadolo. Inomumo olingisa i-anatomy yemvelo yethambo ukuyisiza ukuthi ingene ngokuvikelekile ekuhlanganyeleni. Ingxenye yesifazane ivamise ukunamathiselwa ethanjeni ngosimende okhethekile noma ngendlela yokucindezela ukucindezela ekhuthaza ukukhula kwethambo eduze kwesifakelo.
Ngesikhathi se-ukushintshwa kwamadolo ahlangeneukuhlinzwa, udokotela ohlinzayo uzokwenza ukusika edolweni futhi asuse ingxenye eyonakele ye-femur. Udokotela ohlinzayo uyobe eselungisa ithambo ukuze lithole ukufakelwa kwengxenye yesifazane. Ingxenye yesifazane izobekwa futhi iqiniswe endaweni kusetshenziswa usimende wethambo noma indlela yokulinganisa ukucindezela. Uma ingxenye yesifazane isisendaweni, udokotela ohlinzayo uzovala ukusika futhi isiguli sizoqala inqubo yokutakula. Ngemuva kokuhlinzwa, iziguli ngokuvamile zizodinga ukuhlanganyela ekuzivocavoca umzimba ukusiza ukuqinisa amadolo nokukhuthaza ukuphulukiswa. Ngemva kwezinyanga ezimbalwa zokuvuselelwa, iziguli ngokuvamile zingalindela ukuthi amadolo azizwe engcono kakhulu futhi abe nokusebenza okuthuthukisiwe. Kodwa-ke, kubalulekile ukulandela noma yimiphi imiyalelo yangemva kokuhlinzwa enikezwa udokotela ohlinzayo ukuze kuqinisekiswe ukuphulukiswa okuphelele nokululama.
Gwema i-pendency ngezici ezintathu
1.I-multi-radius design inikezas 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
Imininingwane Yokwenziwa Kwamalungu Edolo
