No nā mea kūʻai e ʻimi nei i nā MOQ haʻahaʻa a me nā ʻano huahana kiʻekiʻe, hāʻawi ʻo Multispecialty Suppliers i ka hoʻopilikino MOQ haʻahaʻa, nā hoʻonā logistics end-to-end, a me ke kūʻai ʻana ma nā ʻano he nui, i kākoʻo ʻia e kā lākou ʻike ʻoihana a me ka lawelawe waiwai a me ka hoʻomaopopo ikaika i nā ʻano huahana e kū mai ana.
I. He aha nā ʻano ʻehā o nā haki femoral?
1. Ka haki ʻana o ka femur proximal
Ka haki ʻāʻī o ka femoral: He mea maʻamau ia i nā poʻe maʻi ʻelemakule me ka osteoporosis a hiki ke alakaʻi maʻalahi i ka ischemia a me ka necrosis o ke poʻo femoral.
Haʻihaʻi Intertrochanteric: Aia ka laina haki ma waena o ka trochanter nui a me ka trochanter liʻiliʻi, me ka lako koko maikaʻi a me ka wikiwiki ho'ōla kiʻekiʻe.
Nā haki subtrochanteric: hana ʻia ma lalo o ka trochanter liʻiliʻi, i hoʻokumu pinepine ʻia e nā ʻeha ikaika nui, a koi pinepine ʻia ke ʻoki kino.
2. Ka haki ʻana o ke koʻokoʻo femoral
Hiki mai nā haki ma waenakonu o ka femur a pinepine ʻia e ka hana ʻino pololei (e like me nā ulia kaʻa, hāʻule ʻana), hele pinepine ʻia e ka neʻe nui ʻana a me ka hōʻino ʻana o nā ʻiʻo palupalu.
3. Ka haki ʻana o ka femur distal
ʻO ka haki supracondylar o ka femur: kokoke i ka hui kuli, hiki ke pili i ka ʻili articular, a koi ʻia ka hoʻemi anatomical e hoʻihoʻi i ka hana hui.
Nā haki intercondylar Interfemoral: e pili ana i nā condyles femoral medial a me waho, pono e loiloi ʻia ka flatness o ka mokulele articular e pale aku i ka maʻi arthritis traumatic.
Ⅱ. He aha nā hana palekana e pono e hana ʻia i ka wā o ke ʻoki ʻana i nā kui femoral?
Ma hope o ke ʻoki ʻana, pono e uku ʻia ka nānā nui i nā ʻano penei: ʻO ka mea mua, e makaʻala i ke kahe ʻana o ke koko o ka ʻoki ʻoki, a e hoʻohana pono i nā antibiotics no 24 ~ 48 mau hola ma hope o ke ʻoki ʻana e pale aku i ka maʻi. Hoʻololi pinepine ʻia ka ʻoki ʻoki, a wehe ʻia ka wai hoʻokahe i loko o 24 mau hola. ʻO ka lua, e hana i nā hana hui hip a me ke kuli a me nā hoʻomaʻamaʻa hana i ka hikiwawe loa ma hope o ke ʻoki ʻana. ʻO nā kui intramedullary no nā haki ʻana o ke koʻokoʻo femoral e komo pū me nā kui e pono e kui ʻia ma o nā hui hip a kuli paha, kahi e hōʻino ai i nā ʻiʻo palupalu a puni nā hono a hiki ke hōʻiliʻili i ke koko i loko o nā hono. No laila, ua ʻōlelo ʻia e hana i ka hoʻoneʻe ʻana o nā hui ma mua o ke ʻoki ʻana e pale aku i nā pilikia e like me nā hoʻopili ʻana o nā hui, a e hōʻemi pū i ka hoʻokumu ʻia ʻana o ka thrombosis vein hohonu ma nā ʻaoʻao haʻahaʻa. ʻO ke kolu, ʻaʻole ʻōlelo ʻia e hāpai i nā kaumaha ma hope o ke ʻoki ʻana, a pono e nānā pinepine i nā kukuna X e hoʻomaopopo i ka ulu ʻana a me ka hoʻōla ʻana o ke kumu haki, a e hoʻolaha i ka hoʻōla pono ʻana o ka haki ma o nā lāʻau lapaʻau.
I. He aha ka ʻokoʻa ma waena o PFN A a me A2?
He ʻelua mau manaʻo like ʻole ka PFN-A a me A2, ʻo ka mea mua he mea hoʻopaʻa kūloko no ka mālama ʻana i nā haki femoral intertrochanteric (anti-rotation proximal femoral intramedullary nail), a ʻo ka mea hope he hoʻokaʻawale ʻana o nā haki femoral intertrochanteric i ka ʻōnaehana AO typing.
ʻO PFN-A kahi mea hana hoʻopaʻa kūloko kūikawā, ʻo ia hoʻi ka "Proximal Femoral Nail Anti-rotation". He ʻōnaehana kui intramedullary ia e hoʻoponopono ana i nā haki ma ke komo ʻana iā lākou i loko o ka lua medullary femoral, me nā ʻano o ka anti-rotation a me ka hoʻopaʻa paʻa, a hoʻohana nui ʻia no ka mālama ʻana i nā haki intertrochanteric o ka femoral femoral me nā ʻano AO A1, A2, A3 a me nā haki subtrochanteric kiʻekiʻe.
ʻO A2 kahi wehewehe ʻano o nā haki femoral intertrochanteric i loko o ka ʻōnaehana hoʻokaʻawale AO a ua hoʻokaʻawale ʻia he haki paʻa ʻole. Wahi a ka hoʻokaʻawale AO, ʻike ʻia nā haki ʻano A2 e kahi laina haki e hele ana ma ka ʻāpana trochanteric a me ka haki ʻana o ka medial cortex ma ka liʻiliʻi he ʻelua mau wahi me ka nui o nā poloka haki. Ua māhele hou ʻia i loko o:
ʻAno A2.1: Aia kahi puʻu haki waena ma waena o nā trochanters.
ʻAno A2.2: Aia kekahi mau poloka haki waena ma waena o nā trochanters.
ʻAno A2.3: ʻOi aku ka lōʻihi o ka laina haki ma mua o 1cm ma lalo o ka trochanter liʻiliʻi
I ka pōkole, he mea hana lapaʻau ʻo PFN-A a ʻo A2 ke ʻano o ka haki. Ma ke ʻano lapaʻau, e koho nā kauka i ke ʻano hoʻopaʻa kūloko kūpono e like me ka hoʻokaʻawale ʻana o AO o ka haki o ka mea maʻi (e like me ke ʻano A2), a ʻo PFN-A kekahi o nā ʻano hana maʻamau no ka mālama ʻana i nā haki femoral intertrochanteric paʻa ʻole e like me ke ʻano A2.
