Izimila Zokufaka Ezishintshayo Ze-Titanium Total Knee Joint Zekhwalithi Ephezulu
Izici ze-Titanium ze-Knee Implants
Izifakelo zokufakelwa kwe-titanium yamadolo ezisezingeni eliphezulu
Ukufakelwa kwamadoloobeye aziwe njengoi-prosthesis yamalunga edolo, yizinto zokwelapha ezisetshenziselwa ukufaka esikhundleni samalunga edolo alimele noma agulayo. Zivame ukusetshenziswa ukwelapha iziguli ezine-arthritis enzima, ukulimala, noma ezinye izimo ezibangela ubuhlungu obungapheli bedolo kanye nokuhamba okulinganiselwe. Inhloso eyinhloko yokufakelwa kwamalunga edolo ukunciphisa ubuhlungu, ukubuyisela ukusebenza, kanye nokuthuthukisa ikhwalithi yokuphila iyonke yeziguli ezine-degeneration enkulu yamalunga edolo.
Ingxenye yesifazane ye-aukushintshwa kwejoyinti ledoloyingxenye yensimbi noma ye-ceramic ethatha indawo yengxenye yethambo lethanga (i-femur) ejoyintini ledolo. Inesimo esilingisa ukwakheka kwemvelo kwethambo ukuze lingene kahle ejoyintini. Ingxenye ye-femoral ivame ukunamatheliswa ethanjeni ngesamente ekhethekile noma ngendlela yokucindezela ekhuthaza ukukhula kwamathambo azungeze i-implant.
Ngesikhathiukushintshwa kwejoyinti ledoloNgemva kokuhlinzwa, udokotela ohlinzayo uzokwenza i-incision edolweni bese esusa ingxenye eyonakele ye-femur. Udokotela ohlinzayo uzobe eselungiselela ithambo ukuze lithole i-femoral component implant. Ingxenye ye-femoral izobekwa futhi ivalwe endaweni yayo kusetshenziswa usimende wethambo noma indlela yokucindezela. Uma ingxenye ye-femoral isikhona, udokotela ohlinzayo uzovala i-incision bese isiguli siqala inqubo yokululama. Ngemva kokuhlinzwa, iziguli ngokuvamile kuzodingeka zihlanganyele ekuzilolongeni kokwelashwa ngokomzimba ukusiza ukuqinisa idolo nokukhuthaza ukuphulukiswa. Ngemva kwezinyanga ezimbalwa zokuvuselelwa, iziguli ngokuvamile zingalindela ukuthi idolo lizizwe lingcono kakhulu futhi libe nokusebenza okuthuthukisiwe. Kodwa-ke, kubalulekile ukulandela noma yimiphi imiyalelo yangemva kokuhlinzwa enikezwa udokotela ohlinzayo ukuqinisekisa ukuphulukiswa nokululama okuhle kakhulu.
Gwema ukuthambekela ngezici ezintathu
1. Umklamo we-radius eminingi unikezainkululeko yokugoba nokujikeleza.
2. Umklamo werediyasi enciphayo yama-J curve femoral condyles ungathwala indawo yokuxhumana ngesikhathi sokugoba okuphezulu futhi ugweme ukumba okufakiwe.
Umklamo obucayi we-POST-CAM ufeza i-osteotomy encane ye-intercondylar ye-PS prosthesis. Ibhuloho lamathambo eliqhubekayo elingaphambili eligciniwe linciphisa ingozi yokuqhekeka.
Idizayini ye-trochlear groove efanele
I-patellatrajectory evamile iyisimo sika-S.
● Vimbela ukuthambekela kwe-patella medial ngesikhathi sokugoba okukhulu, lapho idolo kanye ne-patella kunamandla okusika kakhulu.
● Ungavumeli umugqa ophakathi nendawo we-patella trajectory.
1. Ama-wedge afanelana
2. Udonga oluseceleni olucwebezelisiwe kakhulu lugwema ukuklwebheka ngemuva kokukhubeka.
3. Ibhokisi elivulekile le-intercondylar ligwema ukuklwebheka kwengxenye ephezulu yeposi.
Ukugoba okungu-155 degrees kungabakufeziwengobuchwepheshe obuhle bokuhlinzwa kanye nokuzivocavoca okusebenzayo
Amakhoni okuphrinta e-3D okugcwalisa amaphutha amakhulu e-metaphyseal ngensimbi enezimbobo ukuze kungene ukukhula.
Izinkomba Zokufaka I-Knee Joint
Isifo samathambo esibizwa ngokuthi i-rheumatoid arthritis
I-arthritis yangemva kwenhlekelele, i-osteoarthritis noma i-arthritis ewohlokayo
Ukwehluleka kwe-osteotomy noma ukushintshwa kwe-unicompartmental noma ukushintshwa kwedolo lonke
Imininingwane Yokufakelwa Kwamalunga Edolweni
