Pehea ka lōʻihi o kahi prosthesis pani pani?

ʻO ka hip arthroplasty kahi kaʻina hana ʻoi aku ka maikaʻi no ka mālama ʻana i ka necrosis poʻo femoral, osteoarthritis o ka hui pūhaka, a me nā haʻihaʻi o ke poʻo.femoralʻāʻī i ka wā ʻelemakule. ʻO ka hip arthroplasty i kēia manawa he kaʻina hana ʻoi aʻe e ulu mālie a hiki ke hoʻopau ʻia ma kekahi mau halemai kuaʻāina. Me ka piʻi ʻana o ka nui o nā maʻi pani pani, hopohopo pinepine nā poʻe maʻi e pili ana i ka lōʻihi o ka hana ʻana o ka prosthesis ma hope o ke kāpili ʻana i ka hip a inā paha e mau ia i ke ola. ʻO ka ʻoiaʻiʻo, pehea ka lōʻihi o ka hoʻohana ʻana i ka hoʻololi ʻana o ka ʻūhā ma hope o ke ʻoki ʻana ma muli o ʻekolu mau mea nui: 1, ke koho ʻana i nā mea: i kēia manawa aia ʻekolu mau mea nui no nā hui hip artificial: ① poʻo ceramic + kīʻaha ceramic: ʻoi aku ka kiʻekiʻe o ke kumukūʻai. ʻO ka pōmaikaʻi nui o kēia hui ʻana, ʻoi aku ka maikaʻi o ka lole. I loko o ka ceramic a me ka ceramic friction, ka ia ukana, aahu a me ka waimaka e pili ana i ka metala interface ua nui ka liʻiliʻi, a me nā mea liʻiliʻi liʻiliʻi i waiho ʻia i loko o ka lua hui ma muli o ka ʻaʻahu a me ka waimaka he mea liʻiliʻi loa ia, ʻaʻohe ʻano hōʻole kino e ʻaʻahu i nā ʻāpana. Eia nō naʻe, i ka hihia o ka hana koʻikoʻi a i ʻole ke kūlana kūpono ʻole, aia kahi pilikia liʻiliʻi o ka haki ʻana i ka ceramic. He liʻiliʻi nō hoʻi nā poʻe maʻi i ʻike i ka leo "creaking" ma muli o ka friction ceramic i ka wā o ka hana.

②Poʻo metala + kīʻaha polyethylene: ʻoi aku ka lōʻihi o ka mōʻaukala noiʻi a he hui maʻamau. Metala a hiki i ka polymer polyethylene ultra-kiʻekiʻe, ʻaʻole i ʻike ʻia i ka hana he ʻano ʻino, a ʻaʻole e haki a pēlā aku. Eia naʻe, ke hoʻohālikelike ʻia me ka ceramic a me ka ceramic friction interface, ʻoi aku ka liʻiliʻi ma lalo o ka ukana hoʻokahi no ka manawa like. A i loko o kahi liʻiliʻi loa o nā maʻi maʻalahi, e pane ia i ka pau ʻana o ka ʻōpala, e hoʻoulu ai i ka mumū a puni ka ʻōpala o ka lole i ka pane, a me ka ʻeha a puni ka prosthesis, ka wehe ʻana o ka prosthesis, etc. Eia nō naʻe, hiki i kēia interface ke hana i ka nui o nā ʻāpana metala, hiki ke phagocytosed i kēia mau mea e nā macrophages, e hana ana i kahi ʻano kino ʻē aʻe, hiki ke komo i nā ion metala i loko o ke koko, e hoʻoulu ai i kahi hopena maʻi i loko o ke kino. I kēia mau makahiki i hala iho nei, ua hoʻopau ʻia kēia ʻano o nā hui kikowaena. ④ ʻO ke poʻo seramika i ka polyethylene: ʻOi aku ka paʻakikī o nā poʻo seramika ma mua o ka metala a ʻo ia ka mea i hoʻopaʻa ʻia i ka ʻōpala. ʻO ka seramika i hoʻohana ʻia i kēia manawa i ka ʻoki ʻana i ka hui pū ʻana, he ʻili paʻakikī, pale ʻole, ʻoi loa ka maʻalahi i hiki ke hōʻemi nui i ka nui o ka lole o nā pilina polyethylene friction. ʻOi aku ka liʻiliʻi o ka hiki ke hoʻohana ʻia o kēia implant ma mua o ka metala i ka polyethylene, ʻo ia hoʻi, ʻoi aku ka paʻa ʻana o ka seramika i ka polyethylene ma mua o ka metala i ka polyethylene! No laila, ʻo ka hui hip artificial maikaʻi loa, maʻemaʻe ma ke ʻano o nā mea, he hui hui ceramic-to-ceramic. ʻO ke kumu o ka lōʻihi o ka lawelawe ʻana o kēia hui ʻana, ʻo ia ka hoʻemi ʻana o ka lole i nā manawa he ʻumi a hiki i nā haneli mau manawa i hoʻohālikelike ʻia i nā hui mua, e hoʻolōʻihi nui i ka manawa o ka hoʻohana ʻana, a ʻo nā mea ʻaʻahu he mau mineral kūpono i ke kanaka ʻaʻole i kumu i ka osteolysis a me ka osteoporosis a puni ka prosthesis, ʻoi aku ka maikaʻi no nā maʻi ʻōpio me ka hana kiʻekiʻe. 2. Hoʻokomo pololei i ka prosthesis hip: ma o ka hoʻokomo pono ʻana o ka prosthesis i ka wā o ke kaʻa ʻana, ka acetabulum a me ka femoral stalk ʻO ka hoʻopaʻa paʻa ʻana o ka prosthesis a me ke kihi kūpono e hana ai i ka prosthesis ʻaʻole e noʻonoʻo a hoʻokaʻawale ʻia, no laila ʻaʻole e hoʻokuʻu i ka prosthesis.

ʻO ka pale o kā lākou hui pūhaka ponoʻī: e hoʻemi i ka lawe ʻana i ke kaumaha, nā hana koʻikoʻi (e like me ka piʻi ʻana a me ke kaumaha lōʻihi, a me nā mea ʻē aʻe) e hōʻemi i ka ʻaʻahu a me ka waimaka o ka prosthesis. Eia kekahi, e pale i nāʻeha, no ka mea, hiki i kaʻeha ke alakaʻi i nā haʻihaʻi e pili ana i ka'ōpū o ka'ūhā, hiki ke alakaʻi i ka weheʻana o ka'ōpū.

No laila, hana ʻia nā prostheses i nā mea liʻiliʻi abrasive, hoʻokomo pololei o kahui pūhakaa ʻo ka pale pono ʻana o ka ʻūhā e hiki ke hoʻolōʻihi i ka prosthesis, ʻoiai no ke ola.
