No nā poʻe maʻi e kokoke ana e loaʻa kahi pani hip a i ʻole e noʻonoʻo ana i kahi pani hip i ka wā e hiki mai ana, nui nā hoʻoholo koʻikoʻi e hana ai. ʻO kahi hoʻoholo koʻikoʻi ʻo ke koho ʻana i ka ʻili kākoʻo prosthetic no ka hoʻololi ʻana: metala-ma-metala, metala-ma-polyethylene, ceramic-on-polyethylene, a i ʻole ceramic-on-ceramic. I kekahi manawa, he pilikia kēia!
Hiki ke hoʻohana ʻia ke ʻoki ʻana i ka ʻūhā holoʻokoʻa no ke pani ʻana i kahi hui ʻāʻī o ka ʻāʻī, me ka hoʻohana ʻana i ka prosthesis hui pūlima e hoʻopau i ka ʻeha i hana ʻia e ka hamo ʻana i nā ʻili.
Hoʻolālā ʻia nā prostheses hui pū ʻia e hāʻawi i nā poʻe maʻi me ka ʻoi aku ka paʻa a me ka liʻiliʻi o ka lole a me ka waimaka. Ua hoʻohana ʻia nā metala kuʻuna a me ka polyethylene implants mai ka makahiki 1960, akā ʻo ka holomua o ka ʻenehana i alakaʻi i ka keramika a me nā mea ʻē aʻe e lilo i mea kaulana.
ʻO nā mea implant pani pani pani
ʻO kekahi o nā pilikia maʻamau ma hope o ka hoʻololi ʻana i ka ʻūhā, ʻo ia ka lole a me ka waimaka o ka prosthesis hui mai ka hoʻohana maʻamau. Ma muli o nā kūlana kūikawā o ka mea maʻi, e like me ka makahiki, ka nui, ka pae hana, a me ka ʻike o ke kauka lapaʻau me ka implant kikoʻī, hiki ke hana ʻia kahi prosthesis pani pani i ka metala, polyethylene (plastic), a i ʻole keramic. No ka laʻana, inā ʻeleʻele a ʻōpio paha ka mea maʻi a koi i kahi kiʻekiʻe o ka neʻe ʻana ma hope o ke kaʻina hana, hiki i ke kauka orthopedic ke ʻōlelo aku i kahi implant hip ceramic.
1、Poʻo kinipōpō metalaa me ka uhi ʻana o ka polyethylene (plastic).
Ua hoʻohana ʻia nā pōpō metala maʻamau a me nā liner kīʻaha polyethylene mai ka hoʻomaka ʻana o nā makahiki 1960. Hōʻike ka noiʻi ʻepekema ʻo ka hoʻohana ʻana i nā laina polyethylene i hoʻomaikaʻi ʻia, i kapa ʻia ʻo "highly cross-linked" polyethylene liners, hiki ke hoʻemi nui i ka nui o ka ʻaʻahu o nā implants. Ma muli o kona lōʻihi a me nā waiwai ʻē aʻe e pili ana, ʻo ka metallic polyethylene ka mea i koho ʻia no nā kauka lapaʻau orthopedic no nā ʻāpana hip artificial mai ka wā i hana ʻia ai nā ʻoki ʻoki mua. Hana ʻia ka pōpō metala me ka cobalt-chromium alloy a ʻo ka uhi ʻana i hana ʻia me ka polyethylene.
2、Poʻo kinipōpō seramikaa me ka uhi ʻana o ka polyethylene (plastic).
ʻOi aku ka paʻakikī o nā ʻōlelo aʻoaʻo seramika ma mua o ka metala a ʻo ia ka mea implant pale ʻoi loa. ʻO nā keramika i hoʻohana ʻia i kēia manawa i nā ʻokiʻoki hui pū ʻana he mau ʻili paʻakikī, pale ʻole, ultra-smooth i hiki ke hoʻemi nui i ka nui o ka hoʻohana ʻana o nā pilina polyethylene friction. ʻOi aku ka haʻahaʻa o ka hiki ke hoʻohana ʻia o kēia implant ma mua o ka hiki ke hoʻohana ʻia o ka metala ma ka polyethylene.
3、Poʻo kinipōpō metala a me ka liner metala
Ua hoʻohana ʻia nā mea hoʻoheheʻe metala-ma-metal (kobalt-chromium alloys, i kekahi manawa he kila kila) i ka makahiki 1955, akā ʻaʻole i ʻae ʻia e ka FDA no ka hoʻohana ʻana ma ʻAmelika a hiki i ka makahiki 1999. I ka holomua ʻana o ka ʻenehana, ua hoʻemi nui ʻia ka lole, e hopena i ka liʻiliʻi a me ka nalowale o ka iwi. Loaʻa nā bearings metal i nā ʻano nui (mai ka 28mm a hiki i ka 60mm), a me nā koho lōʻihi o ka ʻāʻī. Eia naʻe, hōʻike nā hōʻike postoperative lōʻihi i ka metala, ma ke ʻano he ion ʻeleʻele, e hōʻiliʻili i nā ʻōpala metala ma muli o ka ʻaʻahu lōʻihi a me ka waimaka, hiki ke alakaʻi i ka hoʻoheheʻe ʻana o ka iwi a puni ka prosthesis hui, i ka hopena i ka hemo a me ka deformation o ka prosthesis hui. Ua hāʻule ka hana.
4、Poʻo kinipōpō seramika akaʻa seramika
I loko o kēia mau pūhaka, ua hoʻololi ʻia nā pōpō metala kuʻuna a me nā liner polyethylene e nā seramika ikaika kiʻekiʻe, i ʻike ʻia no ko lākou mau ʻano ultra-low-wear. Eia nō naʻe, ʻoiai ka loaʻa ʻana o nā pono o ke kiʻekiʻe kiʻekiʻe a me ka lole haʻahaʻa, loaʻa iā lākou ka hemahema o ke kumukūʻai kiʻekiʻe.
E hoʻoholo ʻia ka koho hope loa o ka implant e pili ana i nā kumu olakino kikoʻī o ka mea maʻi a e koi pū kekahi i ka loea o ke kauka orthopedic, hoʻonaʻauao, a me ka ʻike e hoʻopilikino i ka huahana a ka mea hana. No laila, pono e kūkākūkā me kāu kauka lapaʻau orthopedic ma mua o ka hoʻomaʻamaʻa ʻana e hoʻomaopopo i ke ʻano o ka implant a lākou i manaʻo ai e hoʻohana no kāu ʻoki pani pani ʻana, a me nā kumu no ke koho ʻana i kahi implant kikoʻī.
