Ma implants apamwamba a titaniyamu olowa m'malo mwa bondo
Kuyika bondoamadziwikanso kutiprosthesis ya bondo, ndi zipangizo zamankhwala zomwe zimagwiritsidwa ntchito m'malo mwa mawondo owonongeka kapena odwala. Amagwiritsidwa ntchito pochiza odwala omwe ali ndi nyamakazi yoopsa, kuvulala, kapena zina zomwe zimayambitsa kupweteka kwa mawondo osatha komanso kuyenda kochepa. Cholinga chachikulu cha ma implants a mawondo ndi kuthetsa ululu, kubwezeretsa ntchito, ndi kukonza moyo wonse wa odwala omwe ali ndi vuto lalikulu la mawondo.
Gawo lachikazi la abondo olowa m'malondi chidutswa chachitsulo kapena ceramic chomwe chimalowetsa kumapeto kwa ntchafu (femur) mu bondo. Ili ndi mawonekedwe omwe amatsanzira mawonekedwe achilengedwe a fupa kuti athandizire kuti azitha kulowa molumikizana bwino. Gawo lachikazi limamangiriridwa ku fupa ndi simenti yapadera kapena pogwiritsa ntchito makina osindikizira omwe amalimbikitsa kukula kwa fupa kuzungulira fupa.
Pa nthawi yabondo olowa m'maloopaleshoni, dokotala wa opaleshoni amadula bondo ndikuchotsa gawo lowonongeka la femur. Dokotalayo adzakonza fupalo kuti lilandire chigawo cha chikazi. Gawo lachikazi lidzayimitsidwa ndikutetezedwa pogwiritsa ntchito simenti ya mafupa kapena njira yosindikizira. Chigawo cha chikazi chikakhazikitsidwa, dokotalayo adzatseka chigawocho ndipo wodwalayo ayambe kuchira. Pambuyo pa opaleshoni, odwala amafunika kuchita nawo masewera olimbitsa thupi kuti alimbikitse bondo ndikulimbikitsa machiritso. Pambuyo pa miyezi ingapo yakukonzanso, odwala amatha kuyembekezera kuti bondo limve bwino komanso kuti lizigwira ntchito bwino. Komabe, ndikofunikira kutsatira malangizo aliwonse omwe aperekedwa pambuyo pa opaleshoniyo kuti atsimikizire kuchira komanso kuchira.
Pewani pendency ndi zinthu zitatu
1.Mapangidwe amitundu yambiri amaperekas ufulu wokhotakhota ndi kuzungulira.
2.Mapangidwe a decrescent radius a J curve femoral condyles amatha kunyamula malo okhudzana ndi kusinthasintha kwakukulu ndikupewa kuyika kukumba.
Mapangidwe osakhwima a POST-CAM amakwaniritsa osteotomy yaing'ono ya intercondylar ya PS prosthesis. Mlatho wosungidwa wapambuyo wopitilira wa mafupa umachepetsa chiopsezo chothyoka.
Mapangidwe abwino a trochlear groove
Patellatrajectory yodziwika bwino ndi mawonekedwe a S.
● Pewani kukondera kwa patella panthawi yopindika kwambiri, pamene bondo ndi patella zimakhala ndi mphamvu yometa ubweya wambiri.
● Musalole patella trajectory cross center line.
1.Matchable wedges
2.The kwambiri opukutidwa intercondylar mbali khoma amapewa post abrasion.
3.Bokosi lotseguka la intercondylar limapewa kuphulika kwa post top.
Flexion 155 digiri ikhoza kukhalazathekandi njira yabwino yopangira opaleshoni komanso masewera olimbitsa thupi
Ma cones osindikizira a 3D kuti mudzaze zolakwika zazikulu za metaphyseal ndi zitsulo zokhala ndi porous kuti zilowetse.
