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
Ma mbale okhoma amapereka kukhazikika kwapamwamba kwa biomechanical, makamaka mu osteoporotic bone.
6. CZMEDITECH Plate Models
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, mbale yotsekera ya anatomical) ndi mbali (mwachitsanzo, mbale yofananira) mbali zonse zimapereka kukhazikika kwa 3D ndikuchepetsa chiopsezo cha postoperative rotational deformity.
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
Kutsekera mbale kumapereka 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
Mbale zoumbidwa zamitundu ina yothyoka (monga mbale zochiritsira za intercondylar ridge) zimakulitsa kufalikira kwa mphamvu ndikufulumizitsa kuchira kwa mafupa.
Makina athu a distal humerus locking plate adapangidwa mwapadera kuti aziphwanya ma distal humeral fractures. Ndi ma anatomical contouring, locking screw teknoloji, ndi mafotokozedwe angapo, imapereka njira zotetezeka, zokhazikika, komanso zosinthika za opaleshoni yachipatala.
