ʻO ka hip arthroplasty kahi hana ʻokiʻoki maikaʻi loa no ka mālama ʻana i ka necrosis poʻo femoral, ka osteoarthritis o ka hui hip, a me nā haki o kaʻūhāʻāʻī i ka wā ʻelemakule. ʻO ka hip arthroplasty i kēia manawa he hana ʻoi aku ka makua e ulu mālie nei ka kaulana a hiki ke hoʻopau ʻia ma kekahi mau haukapila kuaʻāina. Me ka piʻi ʻana o ka nui o nā maʻi pani hip, hopohopo pinepine nā maʻi e pili ana i ka lōʻihi o ka prosthesis ma hope o ke ʻoki pani hip a inā paha e mau ana i ke ola holoʻokoʻa. ʻO ka ʻoiaʻiʻo, pehea ka lōʻihi o ka hoʻohana ʻana i ka pani hui hip ma hope o ke ʻoki ʻana e pili ana i ʻekolu mau ʻano nui: 1, ke koho ʻana o nā mea: i kēia manawa aia ʻekolu mau mea nui no nā hui hip artificial: ① poʻo keramika + kīʻaha keramika: e kiʻekiʻe ke kumukūʻai. ʻO ka pōmaikaʻi nui o kēia hui pū ʻana, ʻoi aku ka pale ʻana i ke komo ʻana. I ka friction keramika a me ka keramika, ʻoi aku ka liʻiliʻi o ka ukana like, ke komo a me ka haehae e pili ana i ka interface metala, a ʻo nā ʻāpana liʻiliʻi i waiho ʻia i loko o ka lua hui ma muli o ke komo a me ka haehae he liʻiliʻi loa hoʻi, ʻaʻohe hopena hōʻole kino i nā ʻāpana komo. Eia nō naʻe, i ka hihia o ka hana ikaika a i ʻole ke kūlana kūpono ʻole, aia kahi liʻiliʻi loa o ka haki keramika. He kakaikahi nō hoʻi nā maʻi e ʻike i kahi leo "creaking" i hoʻokumu ʻia e ka friction keramika i ka wā o ka hana.
②Poʻo metala + kīʻaha polyethylene: ʻoi aku ka lōʻihi o ka mōʻaukala noi a he hui maʻamau. ʻO ka metala a i ka polymer polymer ultra-kiʻekiʻe, ʻaʻole i ʻike ʻia i ka hana he rattle maʻamau, a ʻaʻole e haki a pēlā aku. Eia nō naʻe, i hoʻohālikelike ʻia me ka interface friction ceramic a ceramic, ʻoi aku ka nui o ke komo ʻana ma lalo o ka ukana like no ka manawa like. A i loko o kahi helu liʻiliʻi loa o nā maʻi koʻikoʻi, e pane ia i nā ʻōpala i lalo, e hana ana i ka mumū a puni nā ʻōpala i ka pane ʻana, a me ka ʻeha mālie a puni ka prosthesis, ka wehe ʻana o ka prosthesis, a pēlā aku. ③ Poʻo metala + bushing metala: interface friction metala a metala (cobalt-chromium alloy, i kekahi manawa kila kila) Ua hoʻopili ʻia kēia interface friction i nā makahiki 1960. Eia nō naʻe, hiki i kēia interface ke hana i kahi nui o nā ʻāpana metala, hiki ke phagocytosed kēia mau ʻāpana e macrophages, e hana ana i kahi hopena kino haole, hiki i nā ion metala i hana ʻia ke komo i ke kahe koko, e hoʻoulu ai i kahi hopena allergic i loko o ke kino. I nā makahiki i hala iho nei, ua hoʻopau ʻia kēia ʻano o nā hono interface. ④ Ke poʻo keramika i ka polyethylene: ʻOi aku ka paʻakikī o nā poʻo keramika ma mua o ka metala a ʻo ia ka mea hoʻokomo pale ʻōpala loa. ʻO ka keramika i hoʻohana ʻia i kēia manawa i ke ʻoki hoʻololi hui he ʻili paʻakikī, pale ʻōpala, a laumania loa e hiki ai ke hōʻemi nui i ka nui o ke komo ʻana o nā pilina friction polyethylene. ʻOi aku ka liʻiliʻi o ke komo ʻana o kēia implant ma mua o ka metala i ka polyethylene, ʻo ia hoʻi, ʻoi aku ka pale ʻana o ka keramika i ka polyethylene ma mua o ka metala i ka polyethylene! No laila, ʻo ka hui hip artificial maikaʻi loa, ma ke ʻano o ka mea, he hui interface ceramic-to-ceramic. ʻO ke kumu o ke ola lōʻihi o kēia hui, ʻo ia ka emi ʻana o ka nui o ke komo ʻana i nā manawa he ʻumi a hiki i nā haneli i hoʻohālikelike ʻia me nā hui ma mua, e hoʻolōʻihi nui ana i ka manawa o ka hoʻohana ʻana i nā hui, a ʻo nā ʻāpana komo he mau minelala kūpono i ke kanaka ʻaʻole ia e hoʻoulu i ka osteolysis a me ka osteoporosis a puni ka prosthesis, ʻoi aku ka kūpono no nā poʻe maʻi ʻōpio me ka hana kiʻekiʻe. 2. Ke kau pololei ʻana o ka prosthesis hip: ma o ke kau pololei ʻana o ka prosthesis i ka wā o ke ʻoki ʻana, ka acetabulum a me ke koʻokoʻo femoral ʻO ka paʻa paʻa o ka prosthesis a me ke kihi kūpono e ʻole ai e hoʻopaʻa ʻia a neʻe ʻia ka prosthesis, no laila ʻaʻole ia e hoʻokuʻu i ka prosthesis.
ʻO ka pale ʻana i ko lākou hui ʻūhā ponoʻī: hoʻēmi i ka hāpai kaumaha, nā hana ikaika (e like me ka piʻi ʻana a me ka hāpai kaumaha lōʻihi, a pēlā aku) e hōʻemi i ke komo ʻana a me ka haehae ʻana o ka prosthesis. Eia kekahi, pale i nā ʻeha, no ka mea, hiki i ka trauma ke alakaʻi i nā haki a puni ka prosthesis ʻūhā, hiki ke alakaʻi i ka wehe ʻana o ka prosthesis.
No laila, ʻo nā prostheses hip i hana ʻia me nā mea ʻaʻole i hoʻopōʻino ʻia, kahi i kau pono ʻia ai oʻūhā huia ʻo ka pale pono o ka hui ʻūhā hiki ke hoʻolōʻihi i ka prosthesis, a hiki i ke ola.
