Chikamu chejoini remabvi reFemoral Condyle prosthetic

Tinokupai masisitimu emabvi anochinjika zvakanyanya, masisitimu emabvi anodzvinyirira uye masisitimu emabvi ane tumor. Sisitimu yese yekutsiva mabvi pamusoro pebvi inowanzo kuve nechikamu chefemoral ankle, tibial tray, uye tibial pad. Zvikamu zvayo zvinowanikwa mumhando dzakasiyana-siyana kuti zvienderane nezvinodiwa nekiriniki.
Sisitimu yemajoini ebvi inotenderera zvakanyanya: dhizaini yakavhurika yebhokisi rekumashure, inochengetedza huwandu hwemapfupa, inochengetedza kuenderera mberi kwebhonzo re cortical repamberi, dhizaini diki re J re posterior malleolus ye femur, dhizaini yakagadziriswa yecam, yakakodzera kutenderera kwakanyanya, ridge ye 3-degree ye tibial tray medullary cavity stem Dhizaini yetibial tray yakatenderedzwa kumashure, inoisa chimiro che anatomical che tibial osteotomy pamusoro, inovandudza tibial spacer post, uye inowedzera femoral roll mukutenderera kwakanyanya. Tibial spacer yakasungirirwa pamberi kuderedza kukanganiswa ne patella panguva yekutenderera kwakadzika. Mugero we trochlear we femoral ankle wakareba, wakadzika uye wakakombama kuti ugadzirise nzira ye femur, izvo zvinogona kuganhurira kukodzera kwe prosthesis yemabvi.
Sisitimu yekubatanidza mabvi ine restrictive: yakakodzera kutsiviwa kwemabvi ekutanga uye kutsiviwa kwebvi, kugadzirisa kusagadzikana kwedivi uye mipata yekutenderera, J-curve, dhizaini yenzvimbo dzakawanda inoenderana nemuviri wemunhu, inoshandiswa pamwe chete netsono yemedulla kudzoreredza bvi. Kugadzikana, dhizaini yekutambanudza nekuwedzera, inoona kuganhurirwa kweivhu remukati nekunze ±1.2 degrees, kutenderera kwemukati nekunze ±2 degrees, dhizaini yetireyi yetibial symmetrical, 0 degree retroversion angle, kudzoreredzwa kuri nani kwekuwedzera uye mipata yekutenderera, marongero akasiyana uye mamodheru emapedhi, anosangana nezvinodiwa zvekiriniki. Sisitimu yekubatanidza mabvi ese: femoral ankle prosthesis anterior malleolus elevation angle ye5 degrees kudzivirira notch; inter-ankle fossa iri pamberi kuderedza osteotomy, femoral ankle patella chute inofamba ichibuda kunze uye yakadzika, patella haisi nyore kupatsanura, tibial pad inogamuchira kaseti uye Skuruu yakakiyiwa kaviri, pamusoro petiyi yetibial yakakweshwa zvakanyanya, uye mubato wetiyi yetibial unoita kuti simende igare yakasimba.

Kugadzirisa majoini ebvi kunoda kuti upe zvinhu zvakadzama, zvakaita semafirimu eCT, mifananidzo yeMRI nedzimwe ruzivo, kuitira kuti tigone kugadzirisa zvigadzirwa zvakanyatsonaka uye zvine musoro kwauri.
