I-prosthesis ye-titanium yamadolo ethathelwa indawo yi-orthopedic knee joint
I-prosthesis ye-titanium yamadolo ethathelwa indawo yi-orthopedic knee joint
Idolo liyilungu elikhulu kunawo wonke emzimbeni womuntu. Lixhumanisa i-femur yakho ne-tibia yakho. Likusiza ukuthi ume, unyakaze futhi ugcine ibhalansi yakho. Idolo lakho liphinde libe ne-cartilage, njenge-meniscus, kanye ne-ligaments, okuhlanganisa i-anterior cruciate ligament, i-middle cruciate ligament, i-anterior cruciate ligament, kanye ne-anterior cruciate ligament.
Kungani sidingaukushintshwa kwejoyinti ledolo?
Isizathu esivame kakhulu salokhuukuhlinzwa kokushintsha idoloiwukudambisa ubuhlungu obubangelwa yi-arthritis. Abantu abadinga ukuhlinzwa kokufakelwa kwamalunga edolo banenkinga yokuhamba, ukukhuphuka izitebhisi nokuvuka ezihlalweni. Umgomo wokufakelwa kwamalunga edolo ukulungisa ubuso bendawo eyonakele yedolo nokunciphisa ubuhlungu bamadolo obungenakulawulwa ngezinye izindlela zokwelapha. Uma ingxenye yedolo yonakele kuphela, udokotela ohlinzayo ngokuvamile angayifaka esikhundleni saleyo ngxenye. Lokhu kubizwa ngokuthi ukushintshwa kwamalunga okungaphelele. Uma lonke ilungu lidinga ukushintshwa, ukuphela kwethambo le-femur kanye ne-tibia kuzodingeka kushintshwe, futhi lonke ilungu kuzodingeka libe phezulu. Lokhu kubizwa ngokuthiukushintshwa kwedolo eliphelele (i-TKA)Ithambo le-femur kanye ne-tibia kuyimibhobho eqinile enesikhungo esithambile ngaphakathi. Isiphetho sengxenye yokwenziwa sifakwa engxenyeni ephakathi yethambo ethambile.
Gwema ukuthambekela ngezici ezintathu
1. Umklamo we-radius eminingi unikeza
inkululeko 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 yejoyinti ledolo lokufakelwa
