ʻO CDC Ceramic Acetabular liner o ka prosthesis hui pūhaka

ʻO kahi liner ceramic acetabular kahi ʻano ʻāpana kūikawā i hoʻohana ʻia i ka hōʻoki ʻana i ka hip. ʻO ia ka liner prosthetic i hoʻokomo ʻia i loko o ke kīʻaha acetabular (kahi ʻāpana o ka hui pūhaka). Ua hoʻomohala ʻia kona mau ʻili o ka hip arthroplasty (THA) me ke kumu o ka hōʻemi ʻana i ka osteolysis i hoʻohana ʻia i nā maʻi ʻōpio a me nā mea maʻi e hana ana i ka hoʻololi ʻana o ka hip, no laila e hōʻemi ana i ka pono no ka hoʻoponopono hou ʻana o ka aseptic implant.
Hana ʻia nā liners acetabular seramika mai kahi mea seramika, maʻamau ka alumina a i ʻole zirconia. Hāʻawi kēia mau mea i nā mea maikaʻi ma mua o nā mea lining e like me ke metala a i ʻole polyethylene:
1) Kākoʻo ʻaʻahu:
Loaʻa i nā linings seramika ke kūpaʻa maikaʻi loa, ʻo ia hoʻi, ʻaʻole hiki ke ʻaʻahu a haki paha i ka wā. Kōkua kēia i ka hoʻolōʻihi ʻana i ke ola o ka implant a hōʻemi i ka pono no ka hoʻoponopono hou ʻana. Hoʻemi ʻia ka Friction: ʻO ke koena haʻahaʻa o ka friction o nā liner seramika e kōkua i ka hoʻohaʻahaʻa ʻana ma waena o ka liner a me ke poʻo femoral (ke kinipōpō o ka hui pūhaka). Hoʻemi kēia i ka ʻaʻahu a hoʻohaʻahaʻa i ka hiki ke dislocation.
2) Biocompatible:
No ka mea he mau mea biocompatible ka seramika, ʻaʻole hiki ke loaʻa i kahi hopena maikaʻi ʻole i ke kino a i ʻole ka hopena i ka mumū o ke kino. ʻOi aku ka maikaʻi o nā hopena lōʻihi no nā maʻi mai kēia.
