I.Chaniis mitu ya ceramic?
Zipangizo zazikulu zopangira mafupa olumikizirana m'chiuno zimatanthauza zinthu za mutu wa femoral wopangidwa ndi acetabulum. Mawonekedwe ake ndi ofanana ndi mpira ndi mbale zomwe zimagwiritsidwa ntchito kuphwanya adyo. Mpirawo umatanthauza mutu wa femoral ndipo gawo lopindika ndi acetabulum. Cholumikizira chikasuntha, mpirawo umalowa mkati mwa acetabulum, ndipo kusunthaku kungayambitse kukangana. Pofuna kuchepetsa kutopa kwa mutu wa mpira ndikuwonjezera nthawi yogwirira ntchito ya cholumikizira chopangidwa pogwiritsa ntchito mutu wachitsulo woyambirira, mutu wa ceramic unayamba kugwiritsidwa ntchito.
Malumikizidwe achitsulo adapangidwa kale, ndipo dongosolo la opaleshoni ya malumikizidwe achitsulo ndi zitsulo lachotsedwa. Chifukwa chakuti kuchuluka kwa chitsulo pa malumikizidwe apulasitiki ndikokwera nthawi 1,000 kuposa kwa ceramic ndi ceramic, izi zimapangitsa kuti mitu yachitsulo ikhale yochepa.
Kuphatikiza apo, zinthu zopangidwa ndi ceramic zimapanga zinyalala zochepa zikagwiritsidwa ntchito ndipo sizitulutsa ma ayoni achitsulo m'thupi monga mafupa achitsulo. Zimaletsa ma ayoni achitsulo kulowa m'magazi, mkodzo ndi ziwalo zina za thupi, komanso zimapewa zotsatira zoyipa pakati pa maselo ndi minofu ya thupi m'thupi. Zinyalala zomwe zimapangidwa chifukwa cha kukangana kwa mitu yachitsulo zimakhala zovulaza kwambiri kwa akazi a msinkhu wobereka, anthu omwe ali ndi matenda a impso komanso anthu omwe ali ndi vuto la zinyalala zachitsulo.
II.Kodi ubwino wa mitu ya ceramic ndi wotani kuposa mitu yachitsulo?
Kuphatikiza apo, zoumba zomwe zimagwiritsidwa ntchito pochita opaleshoni yobwezeretsa chiuno si zoumba m'njira yathu yachikhalidwe. Monga tafotokozera pamwambapa, m'badwo wachinayi wa zoumba umagwiritsa ntchito zoumba za alumina ndi zoumba za zirconium oxide. Kuuma kwake ndi kwachiwiri kuposa diamondi, zomwe zimatsimikizira kuti pamwamba pake pamakhala posalala komanso kovuta kuvala. Chifukwa chake, nthawi yogwira ntchito ya mitu ya zoumba imatha kufika zaka zoposa 40.
III.Pambuyo pa kuikidwa m'mimbapma rotocols aceramichmitu.
Choyamba, chisamaliro cha zilonda chikufunika. Sungani bala louma komanso loyera, pewani madzi, ndipo pewani matenda. Ndipo bandeji ya zilonda iyenera kusinthidwa nthawi zonse malinga ndi malangizo a ogwira ntchito zachipatala.
Kachiwiri, kutsatiridwa nthawi zonse kumafunika. Nthawi zambiri, kutsatiridwa kumafunika pakatha mwezi umodzi, miyezi itatu, miyezi isanu ndi umodzi ndi chaka chimodzi kuchokera pamene opaleshoni yachitika. Dokotala adzadziwa kuchuluka kwa kutsatiridwa kutengera momwe wodwalayo akuchira pakuwunika kulikonse. Zinthu zotsatiridwa zikuphatikizapo kuyezetsa X-ray, magazi, kuwunika magwiridwe antchito a mafupa a m'chiuno, ndi zina zotero, kuti amvetsetse bwino malo a prosthesis, momwe wodwalayo akuchira komanso momwe thupi lake limachira.
Mu moyo watsiku ndi tsiku, pewani kupindika kwambiri ndi kupotoza cholumikizira cha m'chiuno. Mukakwera ndi kutsika masitepe, mbali yathanzi iyenera kupita kaye, ndipo yesani kugwiritsa ntchito chogwirira kuti chithandize. Ndipo mkati mwa miyezi itatu mutachita opaleshoni, kuchita masewera olimbitsa thupi olemera komanso ntchito zolimbitsa thupi, monga kuthamanga ndi kunyamula zinthu zolemera, ziyenera kupewedwa.
