I-CDC Ceramic Acetabular liner ye-hip joint prosthesis

I-ceramic acetabular liner luhlobo olukhethekileyo lwento esetyenziswa kutyando lokutshintshwa kwe-hip ngokupheleleyo. Yi-prosthetic liner efakwa kwi-acetabular cup (inxalenye yesokhethi ye-hip joint). Iindawo zayo zokuthwala kwi-total hip arthroplasty (THA) zenziwe ngenjongo yokunciphisa i-osteolysis ebangelwa kukuwohloka kwizigulane eziselula nezisebenzayo ezifakelwa i-total hip replacement, ngaloo ndlela kunciphisa imfuneko yokuhlaziywa kwe-aseptic reduction kwangoko kwe-implant.
Ii-ceramic acetabular liners zenziwe ngezinto ze-ceramic, ezidla ngokuba yi-alumina okanye i-zirconia. Ezi zinto zibonelela ngeenzuzo ezininzi ngaphezu kwezinye izinto ze-lining ezifana nesinyithi okanye i-polyethylene:
1) Ukumelana nokunxiba:
Iilinings zeseramikhi zinokumelana okuhle nokuguguleka, nto leyo ethetha ukuba azinakuguguleka okanye ziqhekeke ngokuhamba kwexesha. Oku kunceda ukwandisa ubomi be-implant kwaye kunciphisa isidingo sotyando lokuhlaziya. Ukungqubana okuncitshisiweyo: Umlinganiselo ophantsi wokungqubana kweelinings zeseramikhi kunceda ukunciphisa ukungqubana phakathi kwe-liner kunye nentloko ye-femoral (ibhola yelungu lesinqe). Oku kunciphisa ukuguguleka kwaye kunciphisa amathuba okukhubeka.
2) Iyahambelana ne-biocompatible:
Ngenxa yokuba izinto zobumba zihambelana nendalo, azinakwenzeka ukuba zibe nefuthe elibi emzimbeni okanye zibangele ukudumba kwezicubu. Oku kunokubangela iziphumo ezingcono zexesha elide kwizigulana.
