Femoral Condyle prosthetic pob qij txha

Peb muab cov txheej txheem pob txha caj qaum uas khoov tau zoo, cov txheej txheem pob txha caj qaum uas txwv tsis pub khoov, thiab cov khoom siv pob txha caj qaum uas kho raws li qhov mob qog nqaij hlav. Cov khoom siv pob txha caj qaum uas hloov tau tag nrho feem ntau muaj pob luj taws femoral, lub tais tibial, thiab lub ncoo tibial. Nws cov khoom muaj ntau yam qauv kom tau raws li qhov xav tau ntawm kev kho mob.
Lub cev pob qij txha caj dab siab: qhib lub thawv hloov pauv rov qab, khaws cov pob txha ntim, tswj qhov sib txuas ntawm cov pob txha cortical pem hauv ntej, lub vojvoog me me J-puab tsim ntawm posterior malleolus ntawm femur, tsim cam zoo tshaj plaws, yooj yim rau kev khoov siab, 3-degree ridge ntawm tibial tray medullary cavity qia Posteriorly inclined, anatomical tibial tray tsim ua rau muaj kev npog ntawm tibial osteotomy nto, txhim kho tibial spacer ncej, thiab ua rau femoral dov hauv kev khoov siab. Tibial spacer yog chamfered nyob rau hauv pem hauv ntej kom txo qhov cuam tshuam nrog patella thaum lub sijhawm khoov tob. Lub trochlear groove ntawm femoral pob luj taws yog ntev, tob thiab lateral kom zoo tshaj plaws trajectory ntawm femur, uas tuaj yeem txwv qhov haum dav dav ntawm lub hauv caug pob qij txha prosthesis.
Kev txwv tsis pub siv cov pob qij txha: tsim nyog rau kev hloov pob qij txha thawj zaug thiab kev kho pob qij txha, hloov kho rau qhov tsis ruaj khov thiab qhov sib txawv ntawm lub hauv caug, J-nkhaus, ntau lub voj voog tsim raws li tib neeg lub cev, siv ua ke nrog koob medulla los kho qhov sib koom ua ke ntawm lub hauv caug, kev tsim qauv tom qab dav thiab siab, paub txog qhov txwv ntawm kev tig sab hauv thiab sab nraud ± 1.2 degrees, kev tig sab hauv thiab sab nraud ± 2 degrees, kev tsim qauv tibial symmetrical, lub kaum sab xis 0 degree retroversion, rov qab zoo dua ntawm qhov sib txawv ntawm kev nthuav dav thiab kev hloov pauv, cov lus qhia sib txawv thiab cov qauv ntawm cov ntaub qhwv, ua tau raws li qhov xav tau kev kho mob. Tag nrho cov pob qij txha: femoral pob luj taws prosthesis anterior malleolus elevation kaum sab xis ntawm 5 degrees kom tsis txhob muaj notch; inter-ankle fossa yog anterior kom txo qhov osteotomy, femoral pob luj taws patella chute txav mus rau sab nraud thiab tob zuj zus, patella tsis yooj yim rau dislocate, tibial pad adopts cassette thiab Lub ntsia hlau yog ob chav-xauv, qhov chaw sib cuag ntawm tibial tray yog polished heev, thiab tibial tray tis kov ua kom muaj kev ruaj khov ntawm cov txheej txheem kho cement.

Kev kho kom haum rau lub pob qij txha yuav tsum tau koj muab cov lus qhia ntxaws ntxaws, xws li CT zaj duab xis, MRI duab thiab lwm yam ntaub ntawv, yog li peb tuaj yeem kho cov khoom kom raug thiab tsim nyog tshaj plaws rau koj.
