CDC Ceramic Acetabular liner yehudyu joint prosthesis

A ceramic acetabular liner imhando yakakosha yechikamu chinoshandiswa mukuvhiya kwehudyu kutsiva. Ndiyo prosthetic liner inopinzwa mukapu yeacetabular (socket chikamu chejojo rehudyu). Nzvimbo dzayo dzekutakura muhudyu arthroplasty (THA) dzakagadzirwa nechinangwa chekudzikisa kupfeka-induced osteolysis muvarwere vadiki uye vanoshanda vari pasi pese kutsiva hudyu, nekudaro zvichidzikisira kudiwa kwekutanga kweaseptic kusunungura kudzokororwa kweiyo implant.
Ceramic acetabular liners inogadzirwa kubva kune ceramic zvinhu, kazhinji alumina kana zirconia. Zvishandiso izvi zvinopa zvakati wandei zvakanakira pamusoro pezvimwe zvimisikidzo zvakaita sesimbi kana polyethylene:
1) Wear Resistance:
Ceramic linings ine yakanakisa kupfeka kuramba, zvichireva kuti ivo havagone kupfeka kana kutyora nekufamba kwenguva. Izvi zvinobatsira kurebesa hupenyu hwekuisirwa uye kuderedza kudiwa kwekuvhiyiwa kwekudzokorora. Reduced Friction: The low coefficient of friction of ceramic liners inobatsira kuderedza kukakavara pakati pe liner uye femoral head (bhora rejojo rehudyu). Izvi zvinoderedza kupera uye zvinoderedza mukana wekubvisa.
2) Biocompatible:
Nekuti maceramics ari biocompatible zvinhu, kashoma kuve nemhedzisiro isina kunaka pamuviri kana kukonzera kuzvimba kwenyama. Zvirinani kwenguva refu mhedzisiro yevarwere inogona kubva pane izvi.
