Ingxenye yedolo lokufakelwa le-Femoral Condyle

Sikunikeza amasistimu amadolo aguquguqukayo aphezulu, amasistimu amadolo avimbelayo kanye nezitho zokwenziwa zamadolo zangokwezifiso. I-prosthesis ephelele yokushintshwa kwamadolo ngokuvamile iqukethe i-ankle yesifazane, i-tibial tray, kanye ne-tibial pad. Izingxenye zayo zitholakala ngezindlela ezihlukahlukene ukuze kuhlangatshezwane nezidingo zomtholampilo.
Isistimu ehlangene yamadolo eguquguqukayo: ibhokisi elivulekile elibheke emuva, ligcina ivolumu yethambo, ligcina ukuqhubeka kwethambo le-cortical yangaphambili, i-radius encane efana ne-J-shaped design ye-posterior malleolus ye-femur, i-cam optimized design, elungele ukuguquguquka okuphezulu, i-3-degree ridge ye-tibial tray medullary stem, i-posteriortomical i-design ye-design ye-design medullary ikhulisa i-posteriortomical i-tibial osteotomy surface, ithuthukisa i-tibial spacer post, futhi ikhulise i-femoral roll in high flexion. I-tibial spacer i-chamfered ngaphambili ukuze inciphise umthelela nge-patella ngesikhathi sokuguquguquka okujulile. I-trochlear groove yeqakala lesifazane yinde, ijulile futhi ibheke eceleni ukuze kuthuthukiswe indlela ye-femur, engakhawulela ukulingana okuvamile kwe-prosthesis ehlangene yamadolo.
Isistimu ehlangene yamadolo ekhawulelwe: ilungele ukuguqulwa kwamadolo okuyisisekelo okuyinkimbinkimbi kanye nokuguqulwa kwamadolo esikhundleni, ukujwayela ukungazinzi kwe-lateral kanye nezikhala eziguquguqukayo, i-J-curve, i-multi-radius design ngokuhambisana ne-anatomy yomuntu, esetshenziswa ngokuhambisana nenaliti ye-medulla ukubuyisela ukuhlangana kwamadolo Ukuzinza, ukuklama kokwandisa nokuphakama, ibona ukulinganiselwa kwangaphakathi nangaphandle, ukuphenduka kwenhlabathi yangaphakathi nangaphandle ± 2 ± 2. idizayini yethreyi ye-tibial, i-0 degree retroversion angle, ukutakula okungcono kwegebe lesandiso ne-flexion, ukucaciswa okuhlukile namamodeli wamaphedi, ukuhlangabezana nezidingo zomtholampilo. Uhlelo oluhlangene lwamadolo: i-femoral ankle prosthesis yangaphambili ye-malleolus ephakeme i-angle yama-degree angu-5 ukugwema inothi; I-inter-ankle fossa ingaphambili ukuze kuncishiswe i-osteotomy, i-femoral ankle patella chute iphumela ngaphandle futhi ijule, i-patella akulula ukuyikhipha, i-tibial pad ithatha ikhasethi futhi I-screw ikhiywe kabili, indawo yokuxhumana yethreyi ye-tibial iphucuziwe kakhulu, futhi i-tibial tray wing wing iqinisekisa inqubo yokuzinza.

Ukwenza idolo ngendlela oyifisayo kudinga ukuthi unikeze imingcele enemininingwane, njengamafilimu e-CT, izithombe ze-MRI nolunye ulwazi, ukuze sikwazi ukukwenzela imikhiqizo enembe kakhulu nenengqondo.
