He aha ka ʻāpana liʻiliʻi?
ʻO ka ʻāpana liʻiliʻi e pili ana i ke ʻano o ka implant orthopedic i hoʻohana ʻia no ka hoʻoponopono ʻana i nā iwi liʻiliʻi a me nā ʻāpana iwi, ʻo ka mea maʻamau ka mea i ana 2.0 a 3.5 mm ke anawaena. Hoʻohana mau ʻia kēia mau implants i nā ʻoki lima a me nā wāwae, a me nā hana ʻē aʻe e pili ana i nā ʻāpana iwi liʻiliʻi. Hoʻolālā ʻia nā implants ʻāpana liʻiliʻi e hoʻolako i ka hoʻoponopono paʻa a hoʻoikaika i ka ho'ōla, a loaʻa i nā ʻano like ʻole a me nā ʻano nui e hoʻokō i nā pono ʻokoʻa like ʻole. Hana ʻia lākou me nā mea biocompatible e like me ka titanium a i ʻole ke kila kila, a hoʻokomo pinepine ʻia me ka hoʻohana ʻana i nā mea hana kūikawā.
He aha nā ʻano o nā ʻāpana liʻiliʻi?
Loaʻa nā papa ʻāpana liʻiliʻi i nā ʻano like ʻole a me nā nui e kūpono i nā wahi anatomical like ʻole a me nā nui iwi. ʻO kekahi mau ʻano maʻamau o nā papa ʻāpana liʻiliʻi:
Hoʻokahi hapakolu o nā papa tubular: Hoʻohana ʻia kēia no nā ʻāpana iwi liʻiliʻi a i ʻole nā ʻāpana iwi liʻiliʻi me ka liʻiliʻi o ka wahi no ka hoʻopaʻa ʻana, e like me ka lima, pulima lima, a me nā kuʻekuʻe wāwae.
Nā pā-T: Hoʻohana mau ʻia kēia mau papa i nā haʻihaʻi o ka radius distal, kuʻekuʻe wāwae, a me ka calcaneus.
L-palapala: Hoʻohana ʻia kēia mau papa i nā haʻihaʻi e pono ai ke hoʻopaʻa pololei ʻana i ke koʻi lōʻihi o ka iwi, e like me ka haʻi ʻana o ka femoral femoral.
H-palapala: Hoʻohana ʻia kēia mau papa i nā haʻihaʻi o ka tibia proximal, a me ka mālama ʻana i nā uniona ʻole.
Nā pā-Y: Hoʻohana ʻia kēia mau papa no nā haʻihaʻi o ka humerus proximal, clavicle, a me ka femur distal.
Pāpā Hook: Hoʻohana ʻia kēia mau papa i nā haʻihaʻi paʻakikī kahi i hiki ʻole ai a i ʻole i hāʻule ʻole nā ʻenehana hoʻopaʻa maʻamau, e like me nā haʻihaʻi o ka pāpū tibial lateral.
He mea nui e hoʻomaopopo i nā ʻano a me ka nui o nā papa ʻāpana liʻiliʻi i hoʻohana ʻia e hilinaʻi i ke ʻano haʻihaʻi kikoʻī a me ka makemake o ke kauka.
Nā lako o ka pā paʻa?
Hana ʻia nā papa laka i nā mea biocompatible e like me ka titanium, titanium alloy, a i ʻole ke kila kila. He ikaika maikaʻi loa kēia mau mea, ʻoʻoleʻa, a me ke kūpaʻa ʻana i ka corrosion, e hana maikaʻi iā lākou no ka hoʻohana ʻana i nā implants orthopedic. Eia kekahi, he inert lākou a ʻaʻole e hana me nā ʻiʻo kino, e hōʻemi ana i ka hopena o ka hōʻole ʻana a i ʻole ka mumū. Hiki ke uhi ʻia kekahi mau papa paʻa me nā mea e like me ka hydroxyapatite a i ʻole nā pale ʻē aʻe e hoʻomaikaʻi i ko lākou hoʻohui ʻana me ka iwi iwi.
ʻO wai ka pā i ʻoi aku ka maikaʻi o ka titanium a i ʻole ke kila kila?
Hoʻohana maʻamau ʻia nā papa titanium a me ke kila kila i nā orthopedic orthopedic, me ka hoʻopaʻa ʻana i nā papa. ʻO ka koho ma waena o nā mea ʻelua e pili ana i nā kumu he nui, me ke ʻano o ke kaʻina hana, ka mōʻaukala olakino a me nā makemake o ka mea maʻi, a me ka ʻike a me ka makemake o ke kauka.
ʻO ka Titanium kahi mea māmā a ikaika i biocompatible a kūpaʻa i ka corrosion, e lilo ia i koho maikaʻi loa no nā implants olakino. ʻAʻole ʻoi aku ka paʻakikī o nā pā Titanium ma mua o nā pā kila kila, hiki ke kōkua i ka hōʻemi ʻana i ke kaumaha ma ka iwi a hoʻoikaika i ka ho'ōla. Eia kekahi, ʻoi aku ka radiolucent o nā papa titanium, ʻo ia ka mea ʻaʻole lākou e hoʻopilikia i nā hoʻokolohua kiʻi e like me nā X-ray a i ʻole MRI.
ʻO ke kila kila, ma ka ʻaoʻao ʻē aʻe, he mea ikaika a ʻoi aku ka ʻoi aku ka biocompatible a kū i ka corrosion. Ua hoʻohana ʻia ia i nā implants orthopedic no nā makahiki he mau makahiki a he mea hoʻāʻo a ʻoiaʻiʻo. ʻOi aku ke kumukūʻai o nā pā kila kila ma mua o nā pā titanium, hiki ke lilo i mea noʻonoʻo no kekahi mau maʻi.
No ke aha i hoʻohana ʻia ai nā papa titanium i ka hana ʻana?
Hoʻohana pinepine ʻia nā pā Titanium i ka ʻokiʻoki ma muli o kā lākou mau waiwai kūʻokoʻa e lilo ai lākou i mea kūpono no nā implants olakino. ʻO kekahi o nā pōmaikaʻi o ka hoʻohana ʻana i nā papa titanium i ke kaʻina hana:
Biocompatibility: He mea biocompatible loa ka Titanium, ʻo ia hoʻi, ʻaʻole hiki ke hoʻoulu ʻia ka hopena maʻi a hōʻole ʻia paha e ka ʻōnaehana pale o ke kino. He mea palekana a hilinaʻi kēia no ka hoʻohana ʻana i nā implants olakino.
ʻO ka ikaika a me ka lōʻihi: ʻO Titanium kekahi o nā metala ikaika loa a paʻa loa, e lilo ia i mea kūpono no nā implants e pono ai ke kū i nā koʻikoʻi a me nā pilikia o ka hoʻohana ʻana i kēlā me kēia lā.
Ka pale ʻana i ka ʻino: Paʻa loa ka Titanium i ka ʻino a ʻaʻole hiki ke hana me nā wai kino a i ʻole nā mea ʻē aʻe o ke kino. Kōkua kēia i ka pale ʻana i ka implant mai ʻino a hōʻino paha i ka wā.
Radiopacity: He radiopaque nui ka Titanium, ʻo ia hoʻi, hiki ke ʻike maʻalahi ʻia ma nā kukui X a me nā hoʻokolohua kiʻi ʻē aʻe. ʻO kēia ka mea maʻalahi i nā kauka ke nānā i ka implant a hōʻoia i ka hana pono.
