1. Anatomy ya Distal Humerus
The distal humerus imakhala ndi zigawo zapakati ndi zam'mbali, zomwe zimaphatikizapo epicondyles ndi condyles.
2. Njira Yovulaza
Kuthyoka kwa distal humerus kumachitika chifukwa cha kuvulala kwachindunji (mwachitsanzo, kugwa) kapena mphamvu zina (mwachitsanzo, kupindika kapena kukoka minofu).
3. Gulu la AO
Gulu la AO limagawaniza distal humerus fractures mu mitundu itatu ikuluikulu: A , B , ndi C .
4. Chithandizo cha Opaleshoni
Chithandizo cha opaleshoni chimatsatira mfundo za AO: kuchepetsa thupi, kukonza kokhazikika, ndi kukonzanso koyambirira.
5. Kufunika Kwachipatala
Locking plates amapereka kukhazikika kwapamwamba kwa biomechanical, makamaka mu osteoporotic bone.
6. CZMEDITECH Zitsanzo Zambale
CZMEDITECH imapereka mitundu itatu: extraarticular (01.1107), lateral (5100-17), ndi mbale zapakati (5100-18).
Chifukwa chiyani distal humers nthawi zambiri imasweka?
Monga gawo lofunika kwambiri la chigongono, kuthyoka kwa distal humerus nthawi zambiri kumabwera chifukwa cha 'kuvulala kwachindunji' (monga kugwa pansi pa chigongono) kapena 'kuvulala kosadziwika' (monga kupindika kapena kuponya).
- Mphamvu Zokoka Minofu
Chigawo chapakati chimaphatikizapo gawo lapakati la metaphysis ya humerus, epicondyle yapakati, ndi condyle yapakati, kuphatikizapo trochlea ya humer.
· Kugunda kwamphamvu kwa minofu yozungulira mkati
· Kugunda kwamphamvu kwa minofu ya chigongono
- High-Energy Trauma
Mphamvu zakunja monga ngozi zapamsewu kapena kugwa kuchokera pamtunda kungayambitse kusweka kwapang'onopang'ono kapena kuphatikizira pamwamba.
Coronoid Fossa ndi Olecranon Fossa
· Ngozi zapamsewu
·Kugwa kuchokera kutalika
Mfundo Zachithandizo:
Kutsatira filosofi ya AO: 'Kuchepetsa kwa anatomical, kukhazikika kokhazikika, ndi kuchita masewera olimbitsa thupi koyambirira.'
High-Energy Trauma
Mphamvu zakunja monga ngozi zapamsewu kapena kugwa kuchokera pamtunda kungayambitse kusweka kwapang'onopang'ono kapena kuphatikizira pamwamba.

Plate Fixation Strategie
Dual Plate Technique
Oyenera mtundu C fractures. Kukonzekera kuchokera kumbali zonse zapakati (mwachitsanzo, anatomical Locking plate ) ndi lateral (mwachitsanzo, mbale yofananira) mbali zimapereka kukhazikika kwa 3D ndikuchepetsa chiopsezo cha kusokonezeka kwaposachedwa.
Single Plate Technique
Amagwiritsidwa ntchito pamtundu wa A ndi mtundu wa B wosweka pang'ono. Mabale opangidwa kale omwe amafanana ndi distal humerus anatomy amachepetsa kuphatikizika kwa minofu yofewa.
Njira Yosavuta Kwambiri
Kuphatikizidwa ndi percutaneous screw kuyika kuti muchepetse chiopsezo cha matenda ndikusunga magazi a periosteal.
Ubwino wa Biomechanical
Locking plates amapereka kukhazikika kwa angular, makamaka opindulitsa kwa odwala osteoporotic.
Chitsimikizo Chobwezeretsa Ntchito
Kuchepetsa kwa anatomical kumateteza kusuntha kwa chigongono kwambiri, kuchepetsa zovuta monga kusagwirizana kapena malunion.
Makonda Mapangidwe
Ma mbale opangidwa ndi mitundu ina yake yothyoka (monga mbale zochiritsira za intercondylar ridge) zimathandizira kutumiza mphamvu ndikufulumizitsa kuchira kwa mafupa.
Mitundu yathu ya distal humerus Locking plate idapangidwa mwapadera kuti ikhale yovuta kwambiri ya distal humeral fractures. Ndi ma anatomical contouring, Chomangira chokhoma teknoloji, ndi machitidwe angapo, amapereka njira zotetezeka, zokhazikika, komanso zosinthika za opaleshoni yachipatala.
