I-CDC Ceramic Acetabular liner ye-hip joint prosthesis

I-ceramic acetabular liner luhlobo olukhethekileyo lwecandelo elisetyenziselwa utyando olupheleleyo lwe-hip.Yiyo i-prosthetic liner efakwe kwi-cup acetabular (inxalenye yesokhethi ye-hip joint).Umphezulu wayo othwele i-hip arthroplasty (THA) yaphuhliswa ngenjongo yokunciphisa i-osteolysis enxitywayo kwizigulana eziselula nezisebenzayo ezithatha indawo ye-hip epheleleyo, ngaloo ndlela kuncipha ngokwethiyori imfuneko yohlaziyo lokuqala lwe-aseptic lokukhulula ukufakelwa.
Iintsimbi ze-ceramic ze-acetabular zenziwe nge-ceramic material, ngokuqhelekileyo i-alumina okanye i-zirconia.Ezi zixhobo zibonelela ngeengenelo ezininzi ngaphezulu kwezinye izinto zombane ezifana nentsimbi okanye ipolyethylene:
1)Nxiba ukuxhathisa:
I-Ceramic linings inokumelana okugqwesileyo kokunxiba, oku kuthetha ukuba akunakwenzeka ukuba banxibe okanye baphule ngokuhamba kwexesha.Oku kunceda ukwandisa ubomi bokufakelwa kunye nokunciphisa imfuno yokuhlinzwa ngokutsha.Ukunciphisa Ukunciphisa: I-coefficient ephantsi ye-friction ye-ceramic liners inceda ukunciphisa ukungqubuzana phakathi komgca kunye nentloko ye-femoral (ibhola le-hip joint).Oku kunciphisa ukuguga kwaye kunciphisa amathuba okuba kungabikho kwindawo.
2)I-Biocompatible:
Ngenxa yokuba i-ceramics zizinto ezihambelana ne-biocompatible, akunakwenzeka ukuba zibe nefuthe elibi emzimbeni okanye zibangele ukudumba kwezicubu.Iziphumo ezingcono zexesha elide kwizigulane zinokuvela koku.
