Ingxenye yejoyinti yedolo yokufakelwa ye-Femoral Condyle

Sikunikeza izinhlelo zamadolo ezigobekayo kakhulu, izinhlelo zamadolo ezivimbelayo kanye nezinhlobo zokufakelwa zamadolo ezenziwe ngokwezifiso. I-prosthesis ephelele yokufakwa esikhundleni samadolo ngokuvamile iqukethe iqakala le-femoral, ithreyi le-tibial, kanye ne-tibial pad. Izingxenye zayo zitholakala ngezindlela ezahlukahlukene ukuze kuhlangatshezwane nezidingo zomtholampilo.
Uhlelo lokuhlangana kwamadolo olugobile kakhulu: ukwakheka kwebhokisi elivulekile ngemuva, kulondoloza umthamo wamathambo, kugcina ukuqhubeka kwethambo le-cortical elingaphambili, ukwakheka okuncane okufana no-J kwe-posterior malleolus ye-femur, ukwakheka kwe-cam okwenziwe kahle, okulula ukugoba okuphezulu, umugqa wamadigri amathathu we-tibial tray medullary cavity stem Ukwakheka kwe-tibial tray ethambekele ngemuva, okunokwakheka komzimba kwandisa ukumbozwa kobuso be-tibial osteotomy, kuthuthukisa i-tibial spacer post, futhi kwandisa ukugoba kwe-femoral ekugobeni okuphezulu. I-tibial spacer i-chamfered ngaphambili ukuze kuncishiswe umthelela we-patella ngesikhathi sokugoba okujulile. Umsele we-trochlear we-femoral ankle mude, ujulile futhi usemaceleni ukuze kulungiselelwe indlela ye-femur, okungakhawulela ukulingana okuvamile kwe-prosthesis yejoyinti lamadolo.
Uhlelo lokuhlangana kwamadolo olunemingcele: lufanelekela ukushintshwa kwamadolo okuqala okuyinkimbinkimbi kanye nokuguqulwa kwamadolo, luvumelane nokungazinzi kwe-lateral kanye nezikhala zokugoba, i-J-curve, ukwakheka kwe-multi-radius ngokuhambisana nokwakheka komuntu, okusetshenziswa kanye nenaliti ye-medulla ukubuyisela ijoyinti ledolo Ukuqina, ukwakheka kokunwebeka nokuphakama ngemuva kokukhula, kuqaphela ukulinganiselwa kokujika kwenhlabathi yangaphakathi neyangaphandle ± 1.2 degrees, ukujikeleza kwangaphakathi nangaphandle ± 2 degrees, ukwakheka kwethreyi ye-tibial ehambisanayo, i-angle yokubuyela emuva engu-0 degree, ukululama okungcono kwesikhala sokwandiswa kanye ne-flexion, imininingwane ehlukene namamodeli ama-pad, ahlangabezana nezidingo zomtholampilo. Uhlelo lokuhlangana kwamadolo oluphelele: i-femoral ankle prosthesis anterior malleolus elevation angle engama-degrees ama-5 ukugwema ukugoba; i-inter-ankle fossa ingaphambili ukunciphisa i-osteotomy, i-femoral ankle patella chute iyaphuma futhi ijule, i-patella akulula ukuyisusa, i-tibial pad ithatha ikhasethi futhi Isikulufu sivalwe kabili, ubuso bokuthintana kwethreyi ye-tibial bucwebezelisiwe kakhulu, kanti isibambo sephiko lethreyi ye-tibial siqinisekisa ukuzinza kwenqubo yokwelapha usimende.

Ukwenza ngokwezifiso idolo kudinga ukuthi unikeze imingcele eningiliziwe, njengefilimu ze-CT, izithombe ze-MRI kanye nolunye ulwazi, ukuze sikwazi ukwenza ngokwezifiso imikhiqizo enembile nenengqondo kakhulu kuwe.
