I-CDC Ceramic Acetabular liner ye-hip joint prosthesis

I-ceramic acetabular liner iwuhlobo olukhethekile lwesakhi esisetshenziswa ekuhlinzekweni okuphelele kokushintshwa kwe-hip.Kuyi-liner yokufakelwa efakwa enkomishini ye-acetabular (ingxenye yesokhethi ye-hip joint).Izindawo zayo ezithwalayo ku-hip arthroplasty (THA) ephelele zathuthukiswa ngenhloso yokunciphisa i-osteolysis ebangelwa ukugqokwa ezigulini ezisencane nezikhuthele ezishintshwa ngokuphelele, ngaleyo ndlela kuncipha ngokwephuzu isidingo sokubuyekezwa kokuqala kwe-aseptic okuxega kokufakelwa.
Ama-ceramic acetabular liners enziwe ngezinto zobumba, ngokuvamile i-alumina noma i-zirconia.Lezi zinto zinikeza izinzuzo ezimbalwa ngaphezu kwezinye izinto zokugqoka njengensimbi noma i-polyethylene:
1) I-Wear Resistance:
Izindwangu ze-Ceramic zinokuphikiswa okuhle kakhulu kokugqoka, okusho ukuthi mancane amathuba okuthi zigqokwe noma ziphuke ngokuhamba kwesikhathi.Lokhu kusiza ukwandisa impilo yokufakelwa futhi kunciphisa isidingo sokuhlinzwa okubukeziwe.I-Friction Encishisiwe: I-coefficient ephansi yokungqubuzana kwama-ceramic liners isiza ukunciphisa ukungqubuzana phakathi kwe-liner nekhanda lesifazane (ibhola le-hip joint).Lokhu kunciphisa ukuguga futhi kwehlisa amathuba okugudluka.
2) I-Biocompatible:
Ngenxa yokuthi izitsha zobumba ziyizinto ezihambisana ne-biocompatible, mancane amathuba okuba zibe nomthelela ongemuhle emzimbeni noma zibangele ukuvuvukala kwezicubu.Imiphumela engcono yesikhathi eside yeziguli ingase ibe umphumela walokhu.
