Opanga Apamwamba 5 ku Middle East: Mimbale Yotsekera ya Distal Humerus ( Meyi 2025)
Mawonedwe: 0 Wolemba: Site Editor Nthawi Yosindikiza: 2025-05-22 Origin: Tsamba
Distal humerus fractures ndi mtundu wamba wa kuvulala kwamphamvu kwamphamvu m'mafupa. Kuvuta kwa chithandizo kumakhala muzovuta zamapangidwe a anatomical komanso kufunika kobwezeretsa ntchito yolumikizana. Monga katswiri wopereka yankho pankhani yokonza mafupa amkati, timapereka kusanthula mozama kwa njira zovulaza, gulu la AO, ndi njira zokonzekera mbale za distal humerus fractures kuti tithandizire chithandizo chamankhwala cholondola.
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).
Anatomy ya Distal Humerus
The distal humerus imagawidwa mu gawo lapakati ndi lateral.
Pakati Pakati Chigawo chapakati chimaphatikizapo gawo lapakati la metaphysis ya humerus, epicondyle yapakati, ndi condyle yapakati, kuphatikizapo trochlea ya humer.
Lateral Column Mzere wam'mbali umaphatikizapo mbali ya lateral ya metaphysis ya humerus, epicondyle lateral, ndi lateral condyle, kuphatikizapo capitulum wa humerus.
Coronoid Fossa ndi Olecranon Fossa Pakati pa mizati iwiriyi pali anterior coronoid fossa ndi posterior olecranon fossa.
Njira Zovulaza mu Distal Humerus Fractures
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

Gulu la AO: Kulemba Molondola Kuti Mutsogolere Zosankha Zochita Opaleshoni
Malinga ndi gulu la AO, distal humerus fractures amagawidwa motere, zomwe zimakhudza mwachindunji kusankha njira zamankhwala:
Mtundu A: Ma fractures owonjezera - A1: Kuthyoka kosavuta, palibe kukhudzidwa.
- A2 / A3: Kuwonongeka kwapang'onopang'ono kapena kusamutsidwa kwa metaphyseal, chisamaliro chofunikira pakupunduka kwamakona.
Mtundu B: Kuphulika pang'ono kwa articular Mzere wothyoka umaphatikizapo pamwamba pamtunda koma popanda kupatukana kwathunthu; kuchepetsa anatomical n`kofunika kubwezeretsa olowa conngruency.
Mtundu C: Kuphulika kwathunthu kwa articular - C1 / C2: Kuphulika kosavuta kwa intra-articular ndi kukhudzidwa kwa metaphyseal.
- C3: Kuphwanyidwa kwa intra-articular, zovuta kwambiri kuchiza; kukhazikika kokhazikika ndikofunikira kuti muchepetse chiopsezo cha nyamakazi yowopsa.
Kufunika kwa Gulu: Gulu la AO limamveketsa kuopsa kwa kuthyoka kwake ndipo limapereka chitsogozo chosankha mbale (mwachitsanzo, mbale imodzi vs. yapawiri, zojambula zotsekera zotsekera) kuti zitsimikizire mphamvu zonse zokhazikika komanso kukhazikika kwachilengedwe.
Chithandizo cha Opaleshoni: Ubwino Wapakati pa Plate Fixation
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.
Kuchepetsa kwa anatomical
Kukhazikika kokhazikika
Kuchita masewera olimbitsa thupi koyambirira
Opaleshoni Zizindikiro
Kusamuka kwa Articular> 2mm
Open fractures
Kuvulala kophatikizana kwa neurovascular
Kulephera kwa chithandizo chodziletsa
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.
Kufunika Kwachipatala kwa Plate Fixation
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.
CZMEDITECH Distal Humerus Locking Plate Models
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.
