1. Anatomy o ka Humerus Distal
Aia ka humerus distal i nā kolamu medial a me ka ʻaoʻao, ʻo ia hoʻi nā epicondyles a me nā condyles.
2. Mechanism o ka poino
ʻO nā haʻihaʻi o ka humerus ma muli o ka ʻeha pololei (e laʻa, hāʻule) a i ʻole nā ikaika pololei (e laʻa, wili a huki ʻiʻo paha).
3. Hoʻohui AO
Hoʻokaʻawale ka hoʻohālikelike AO i nā haʻihaʻi humerus distal i ʻekolu ʻano nui: A , B , a me C .
4. Lapaau Opuu
Hoʻopili ka mālama ʻana i nā loina AO: hōʻemi anatomical, hoʻoponopono paʻa, a me ka hoʻoponopono mua.
5. Waiwai Ho'oma'i
Hāʻawi ka paʻa paʻa i ka paʻa biomechanical maikaʻi loa, ʻoi loa i ka iwi osteoporotic.
6. CZMEDITECH Plate Models
Hāʻawi ʻo CZMEDITECH i ʻekolu mau hiʻohiʻona: extraarticular (01.1107), lateral (5100-17), a me nā papa waena (5100-18).
No ke aha i maʻalahi ai ka humerus distal i nā haki?
Ma ke ʻano he ʻāpana koʻikoʻi o ka hui kuʻekuʻe, ʻo ka haʻihaʻi ʻana o ka humerus ma muli o ka 'trauma pololei' (e like me ka pae ʻana i ka kuʻekuʻe) a i ʻole ka 'trauma kūwaho' (e like me ka wili a i ʻole ka hoʻolei ʻana).
- Puʻuwai huki ʻiʻo
Aia ka ʻaoʻao waena o ka metaphysis o ka humerus, ka epicondyle medial, a me ka condyle medial, me ka trochlea o ka humerus.

· ʻO ka ʻoki ikaika ʻana o nā ʻiʻo kuʻekuʻe lima
- Kiekie-Energy Trauma
Hiki i nā mana o waho e like me nā ulia pōpilikia a i ʻole ka hāʻule ʻana mai ke kiʻekiʻe mai ke kiʻekiʻe ke hopena i nā haʻihaʻi comminuted a i ʻole ke komo ʻana i ka ʻili articular.
Coronoid Fossa a me Olecranon Fossa
· Nā pōʻino kaʻa
·Holo mai ke kiʻekiʻe
Nā Kuʻuna Lapaʻau:
Ma muli o ka manaʻo AO: 'Hoʻemi anatomical, hoʻoponopono paʻa, a me ka hoʻoikaika kino mua.'

ʻO ka neʻe ʻana o ka articular >2mm

ʻO ka ʻeha neurovascular i hui pū ʻia
ʻO ka hāʻule ʻole o ka mālama conservative
Papa Paʻa Paʻa
ʻenehana Pāpālua
He kūpono no nā haʻihaʻi ʻano C. ʻO ka hoʻopaʻa ʻana mai nā ʻaoʻao waena (e laʻa, anatomical locking plate) a me ka ʻaoʻao (e laʻa, parallel plate) e hāʻawi i ka paʻa 3D a hoʻemi i ka pilikia o ka hoʻololi ʻana o ka rotational postoperative.
ʻenehana Pāpā hoʻokahi
Hoʻohana ʻia no ka ʻano A a me ka ʻāpana ʻāpana B. ʻO nā papa i hana mua ʻia e like me ka anatomia humerus distal e hōʻemi i ka wehe ʻana o ka ʻiʻo palupalu.
ʻO ke ala hōʻemi liʻiliʻi
Hoʻohui pū ʻia me ka hoʻokomo ʻana i ka wili percutaneous e hōʻemi i ka pilikia o ka maʻi a mālama i ke koko periosteal.
Pōmaikaʻi Biomechanical
Hāʻawi ka laka paʻa i ke kūpaʻa angular, ʻoi aku ka maikaʻi no nā maʻi osteoporotic.
Hōʻoiaʻiʻo hoʻihoʻi hana
Mālama ka hoʻemi anatomical i ka neʻe ʻana o ka hui kuʻekuʻe i ka nui loa, e hōʻemi ana i nā pilikia e like me ka nonunion a i ʻole malunion.
Hoʻolālā hoʻolālā
ʻO nā papa i hana ʻia no nā ʻano haʻihaʻi kikoʻī (e laʻa, nā papa kākoʻo intercondylar ridge) hoʻoikaika i ka hoʻoili ikaika a hoʻolalelale i ka ho'ōla iwi.
Hoʻolālā kūikawā ʻia kā mākou papa hoʻopaʻa paʻa humerus distal no nā haʻihaʻi humeral paʻakikī. Me ka anatomical contouring, ka ʻenehana hoʻopaʻa paʻa, a me nā kikoʻī he nui, hāʻawi ia i nā hopena hoʻoponopono palekana, paʻa, a maʻalahi hoʻi no ka ʻoki kino.
