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.
Uhlelo oluhlangene lwamadolo oluguquguqukayo oluphezulu: ibhokisi elivulekile elibheke emuva, ligcina ivolumu yethambo, ligcina ukuqhubeka kwethambo le-cortical yangaphambili, umklamo omncane omise okwe-J we-posterior malleolus we-femur, umklamo we-cam olungiselelwe, olungele ukuguquguquka okuphezulu, i-3- i-degree ridge ye-tibial tray medullary cavity stem I-posteriorly inclined, i-anatomical tibial tray design yandisa ukumbozwa kwe-tibial osteotomy surface, ithuthukise 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.
Uhlelo oluhlangene lwamadolo oluvimbelayo: lufanele ukushintshwa kwamadolo okuyisisekelo okuyinkimbinkimbi kanye nokuguqulwa kwamadolo okubuyekezwa, ukujwayela ukungazinzi kwe-lateral kanye nezikhala zokuguquguquka, i-J-curve, i-multi-radius design ngokuhambisana ne-anatomy yomuntu, esetshenziswe ngokuhambisana nenaliti ye-medulla ukubuyisela ukuhlangana kwamadolo Ukuzinza. , idizayini yokunwetshwa kwengemuva nokukhulisa ukuphakama, ibona umkhawulo wokuphenduka kwenhlabathi yangaphakathi nangaphandle engu-±1.2 degrees, ukuzungezisa kwangaphakathi nangaphandle okungu-±2 degrees, i-symmetrical tibial tray design, i-0 degree retroversion angle, ukubuyiswa okungcono kwegebe lokunwetshwa ne-flexion, ukucaciswa okuhlukile namamodeli yama pads, 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 kanye nesikulufu sikhiywe kabili, indawo yokuxhumana yethreyi ye-tibial ipholishwe kakhulu, futhi isibambo sephiko le-tibial tray siqinisekisa ukuzinza kwenqubo yokuphulukisa usimende.

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