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 lakumbuyo losinthika, limasunga fupa la fupa, limasunga kupitiriza kwa fupa lakunja la cortical, mawonekedwe ang'onoang'ono a J-mawonekedwe a posterior malleolus a femur, cam cam design, yabwino kusinthasintha kwakukulu, 3- Mzere wa tibial tray medullary cavity tsinde Pambuyo pake, mawonekedwe a anatomical tibial tray amawonjezera kuphimba kwa tibial osteotomy pamwamba, kumapangitsa kuti tibial spacer post, ndikuwonjezera mpukutu wa chikazi pamtunda waukulu.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 la mawondo oletsa mawondo: oyenera m'malo ovuta a mawondo a mawondo ndi kusinthanso mawondo, kusinthana ndi kusakhazikika kwapambuyo ndi mipata yopindika, J-curve, kapangidwe kamitundu yambiri kogwirizana ndi thupi laumunthu, lomwe limagwiritsidwa ntchito molumikizana ndi singano ya medulla kuti abwezeretse mgwirizano wa bondo. , positi kukulitsa ndi kukulitsa kamangidwe, amazindikira malire a mkati ndi kunja kwa nthaka kutembenuka ± 1.2 madigiri, kasinthasintha wamkati ndi kunja ± 2 madigiri, symmetrical tibial tray design, 0 degree retroversion angle, kuchira bwino kwa kufalikira ndi kusiyana kwa flexion, mafotokozedwe osiyanasiyana ndi zitsanzo. a pads, kukwaniritsa 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 achepetse osteotomy, femoral ankle patella chute imayenda panja ndikuzama, patella sivuta kusuntha, tibial pad imatenga kaseti ndipo screw imatsekedwa kawiri, malo olumikizana ndi tibial tray amapukutidwa kwambiri, ndipo chogwirira cha mapiko a tibial chimatsimikizira kukhazikika kwa njira yochiritsira simenti.

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.
