I-CDC Ceramic Acetabular liner ye-prosthesis ye-hip joint

I-ceramic acetabular liner uhlobo olukhethekile lwesakhi esisetshenziswa ekuhlinzeni kokufakwa kwe-hip okuphelele. Yi-prosthetic liner efakwa endebeni ye-acetabular (ingxenye yesokhethi yejoyinti le-hip). Izindawo zayo zokuthwala ku-total hip arthroplasty (THA) zakhiwe ngenhloso yokunciphisa i-osteolysis ebangelwa ukuguguleka ezigulini ezisencane nezisebenzayo ezifakwa esikhundleni se-hip okuphelele, ngaleyo ndlela kunciphisa isidingo sokubuyekezwa kokuqala kokukhululeka kwe-aseptic kwe-implant.
Ama-ceramic acetabular liners enziwe ngezinto zobumba, ngokuvamile i-alumina noma i-zirconia. Lezi zinto zinikeza izinzuzo eziningana ngaphezu kwezinye izinto zobumba ezifana nensimbi noma i-polyethylene:
1) Ukumelana Nokugqokwa:
Izindwangu ze-ceramic zinokumelana okuhle kakhulu nokuguguleka, okusho ukuthi azikwazi ukuguguleka noma ukuphuka ngokuhamba kwesikhathi. Lokhu kusiza ukwandisa impilo ye-implant futhi kunciphisa isidingo sokuhlinzwa kokubuyekezwa. Ukungqubuzana Okuncishisiwe: I-coefficient ephansi yokungqubuzana kwezindwangu ze-ceramic kusiza ukunciphisa ukungqubuzana phakathi kwe-liner nekhanda le-femoral (ibhola le-hip joint). Lokhu kunciphisa ukuguguleka futhi kunciphisa amathuba okukhumuka.
2) Iyahambisana ne-bio:
Ngenxa yokuthi izinto zobumba ziyizinto ezihambisana nemvelo, cishe azinawo umphumela omubi emzimbeni noma ziholele ekuvuvukeni kwezicubu. Imiphumela engcono yesikhathi eside yeziguli ingase ivele ngenxa yalokhu.
