Kaʻana like ʻana i nā hihia lapaʻau-Hoʻololi ʻana i ka hui pūhaka

● ʻIke Kumu: Ms. Chen, wahine, 92 makahiki.
● Wehewehe Pōkole o ke Kūlana: ʻElima mau makahiki i hala aku nei, ua hāʻule ʻo ia a ʻeha ma ka ʻūhā hema. Ua hoʻomaha ʻo ia ma ka home a ua emi iho ka ʻeha. I hoʻokahi mahina i hala aku nei, ua hoʻonui ʻia ka ʻeha o ka ʻūhā hema o ka mea maʻi. I ka hoʻomaka ʻana o Pepeluali o kēia makahiki, ua kipa aku ka mea maʻi i ka Halemai ʻĀpana ʻo Tongliang o Chongqing a ua komo ʻia i ka Joint Department 1 o ka ʻOihana Orthopedics ma muli o ka "haʻi ʻano kahiko o ka ʻāʻī femoral hema; necrosis poʻo femoral hema; hypertension; maʻi puʻuwai coronary".
● Nā Hoʻokolohua Kōkua: Hoʻokolokolo CT, hoʻokolokolo X-ray
● Hōʻike Ma mua o ke ʻoki ʻana: Haʻihaʻi ʻano kahiko o ka ʻāʻī femoral hema; necrosis poʻo femoral hema
● Hoʻolālā Lapaʻau: Hoʻololi piha ʻana i ka ʻūhā o ka ʻaoʻao hema
● Hoʻopau ʻana i ke ʻoki kino: Ma lalo o ke alakaʻi a ke kauka, ua hoʻokomo pono ʻia ka prosthesis hui ʻūhā mai Beijing Zhongantaihua (ZATH). Ua hoʻopau mālie ʻia ke ʻoki kino a ua paʻa nā hōʻailona ola o ka mea maʻi.

He aha nā ʻano prostheses hip i loaʻa?

1, ke poʻo poepoe metala a me ka uhi polyethylene (plastic)
Ua hoʻohana ʻia nā pōpō metala maʻamau a me nā uhi kīʻaha polyethylene mai ka hoʻomaka ʻana o nā makahiki 1960. Hōʻike ka noiʻi ʻepekema e hiki i ka hoʻohana ʻana i nā uhi polyethylene i hoʻomaikaʻi ʻia, i ʻike ʻia ʻo nā uhi polyethylene "cross-linked", ke hōʻemi nui i ka nui o ke komo ʻana o nā implants. Ma muli o kona kūpaʻa a me nā waiwai pili ʻē aʻe, ʻo ka polyethylene metallic ka mea i koho ʻia no nā kauka ʻokiʻoki orthopedic no ka hui ʻūhā artificial mai ka wā i hana ʻia ai nā ʻokiʻoki pani ʻūhā mua. Hana ʻia ka pōpō metala i ka cobalt-chromium alloy a hana ʻia ka uhi i ka polyethylene.

2, ke poʻo pōpō keramika a me ka uhi polyethylene (plastic)
ʻOi aku ka paʻakikī o nā wēlau seramika ma mua o ka metala a ʻo ia ka mea hoʻokomo implant pale loa i ke kahakaha ʻia. ʻO nā seramika i hoʻohana ʻia i kēia manawa i nā ʻoki hoʻololi hui he mau ʻili paʻakikī, pale i ke kahakaha ʻia, a laumania loa e hiki ai ke hōʻemi nui i ka nui o ke komo ʻana o nā pilina friction polyethylene. ʻOi aku ka haʻahaʻa o ka nui o ke komo ʻana o kēia implant ma mua o ka nui o ke komo ʻana o ka metala ma ka polyethylene.

3, ke poʻo poepoe metala a me ka liner metala
Ua hoʻohana ʻia nā pilina friction metal-on-metal (cobalt-chromium alloys, i kekahi manawa kila kila) i ka makahiki 1955, akā ʻaʻole i ʻae ʻia e ka FDA no ka hoʻohana ʻana ma ʻAmelika Hui Pū ʻIa a hiki i ka makahiki 1999. I ka holomua ʻana o ka ʻenehana, ua emi nui ka ʻaʻahu ʻana, e hopena ana i ka emi ʻana o ka mumū a me ka nalowale o ka iwi. Loaʻa nā bearings metal i nā nui like ʻole (mai 28mm a 60mm), a me nā koho lōʻihi o ka ʻāʻī. Eia nō naʻe, hōʻike nā hōʻike postoperative lōʻihi e hōʻiliʻili ka metala, ma ke ʻano he ion hana nui, i nā ʻōpala metala ma muli o ka ʻaʻahu a me ka haehae lōʻihi, hiki ke alakaʻi i ka hoʻoheheʻe ʻana o ka iwi a puni ka prosthesis hui, a i ka hopena e alakaʻi ai i ka wehe ʻana a me ke ʻano o ka prosthesis hui. Ua hāʻule ka hana.

4, ke poʻo pōpō keramika a me ka uhi keramika
I loko o kēia mau ʻōnaehana hui ʻūhā hana, ua pani ʻia nā pōpō metala kuʻuna a me nā liner polyethylene e nā keramika ikaika kiʻekiʻe, i ʻike ʻia no ko lākou mau waiwai haʻahaʻa loa. Eia nō naʻe, ʻoiai he mau pono o ke kūlana kiʻekiʻe a me ka haʻahaʻa o ka ʻaʻahu ʻana, loaʻa pū kekahi iā lākou ka hemahema o ke kumukūʻai kiʻekiʻe.


Inā makemake ʻoe e ʻike hou e pili ana i ka ʻūhā muaka ʻike, e ʻoluʻolu e nīnau maikāhea iā mā˚ou; e hāʻawi kā mākou hui iā ʻoe i ke kākoʻo ʻoihana a me nā pane.
