Femoral Condyle prosthetic bondo gawo limodzi

Timakupatsirani machitidwe opindika kwambiri a mawondo, machitidwe oletsa mawondo ndi ma prostheses amtundu wa chotupa. Bondo lonse la m'malo mwa bondo nthawi zambiri limapangidwa ndi bondo lachikazi, thireyi ya tibial, ndi tibial pad. Zigawo zake zimapezeka muzinthu zosiyanasiyana kuti zikwaniritse zosowa zachipatala.
Mawonekedwe apamwamba a mawondo a mawondo: bokosi lotseguka lakumbuyo losinthika, limasunga fupa la fupa, limasunga kupitiriza kwa anterior cortical bone, mawonekedwe ang'onoang'ono a J-mawonekedwe a posterior malleolus a femur, cam cam design, yabwino kusinthasintha kwakukulu, 3-degree ridge ya tibial tray medullary cavityned tsinde la posteriortomical, posteriortomical cata. tibial osteotomy pamwamba, imapangitsa kuti tibial spacer post, ndikuwonjezera mpukutu wa chikazi mu kusinthasintha kwakukulu. The tibial spacer imayendetsedwa kutsogolo kuti ichepetse kukhudzidwa ndi patella panthawi yakuya. The trochlear groove ya bondo lachikazi ndi lalitali, lakuya komanso lakumbuyo kuti liwongolere njira ya chikazi, zomwe zimatha kuchepetsa kukwanira kwa prosthesis ya bondo.
Dongosolo loletsa mawondo a mawondo: oyenera kusinthika kwa mawondo oyambira ndikusinthanso mawondo, kutengera kusakhazikika kwapambuyo ndi mipata yopindika, J-curve, kapangidwe kamitundu yambiri kogwirizana ndi thupi laumunthu, lomwe limagwiritsidwa ntchito limodzi ndi singano ya medulla kuti abwezeretse mgwirizano wa mawondo Kukhazikika, kukulitsa ndi kukulitsa kapangidwe kake, amazindikira kuchepa kwa mkati ndi kunja kwa madigiri akunja, ± 2 ndi 2. kapangidwe ka tibial tray, 0 degree retroversion angle, kuchira bwino kwa kufalikira ndi kupindika, mawonekedwe osiyanasiyana ndi ma pads, amakwaniritsa zosowa zachipatala. Njira yonse yolumikizira mawondo: prosthesis ya femoral ankle anterior malleolus elevation angle ya madigiri 5 kuti apewe mphako; inter-ankle fossa ndi anterior kuti kuchepetsa osteotomy, femoral ankle patella chute imayenda panja ndikuzama, patella sikophweka kusuntha, tibial pad imatenga kaseti ndipo The screw imatsekedwa kawiri, malo okhudzana ndi tibial tray ndi opukutidwa kwambiri, ndipo tibial tray phiko limatsimikizira kukhazikika kwa njira yokhazikika.

Kusintha mawondo kumafuna kuti mupereke magawo atsatanetsatane, monga mafilimu a CT, zithunzi za MRI ndi zina zambiri, kuti tithe kusintha zinthu zolondola komanso zomveka kwa inu.
