Chovala cha CDC Ceramic Acetabular chopangidwa ndi chiuno cholumikizira

Chovala cha acetabular cha ceramic ndi mtundu wapadera wa chinthu chomwe chimagwiritsidwa ntchito pochita opaleshoni yobwezeretsa chiuno chonse. Ndi chovala chapadera chomwe chimayikidwa mu chikho cha acetabular (gawo la socket la cholumikizira cha chiuno). Malo ake olumikizira mu total hip arthroplasty (THA) adapangidwa ndi cholinga chochepetsa kuwonongeka kwa mafupa mwa odwala achichepere komanso ogwira ntchito omwe akusinthidwa chiuno chonse, motero mwachiphunzitso amachepetsa kufunikira kokonzanso koyambirira kwa aseptic kwa choyikacho.
Zipangizo za ceramic acetabular zimapangidwa kuchokera ku zinthu za ceramic, nthawi zambiri alumina kapena zirconia. Zipangizozi zimapereka ubwino wambiri kuposa zipangizo zina monga chitsulo kapena polyethylene:
1) Kukana Kuvala:
Zipinda za ceramic zimakhala ndi mphamvu yolimba yolimbana ndi kusweka, zomwe zikutanthauza kuti sizingasweke kapena kusweka pakapita nthawi. Izi zimathandiza kutalikitsa moyo wa choyikamo ndipo zimachepetsa kufunika kochita opaleshoni yokonzanso. Kuchepetsa Kusweka: Kuchepa kwa kusweka kwa zipinda za ceramic kumathandiza kuchepetsa kukangana pakati pa chipinda ndi mutu wa femoral (mpira wa cholumikizira cha m'chiuno). Izi zimachepetsa kusweka ndipo zimachepetsa mwayi woti chisasweke.
2) Yogwirizana ndi chilengedwe:
Popeza zinthu zadothi ndi zinthu zogwirizana ndi chilengedwe, sizingakhale ndi zotsatirapo zoipa pa thupi kapena kutupa kwa minofu. Zotsatira zabwino kwa odwala zitha kuchitika chifukwa cha izi.
