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.
Distal Humeral Extraarticular Locking Plate
Mbaleyi idapangidwa kuti ipangike kuti ma fractures amtundu wa distal humerus ayang'ane chigawo cha metaphyseal popanda kuphatikiza pamwamba. Zomangira zake zokhoma zimapereka kukhazikika kwamakona, zomwe zimapangitsa kuti zikhale zoyenera makamaka kwa odwala osteoporotic kapena zovuta zothyoka.

The distal humerus imagawidwa mu gawo lapakati ndi lateral.
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).

Distal Lateral Humeral Locking Plate
Zopangidwira kuti ziwonongeke zam'mbali, mbale iyi ndi yoyenera kwa capitellar kapena supracondylar fractures, kupereka chithandizo chamakina kudzera m'njira yotsatizana kuti athandizire kukonzanso koyambirira.

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 kumafunika kuti muchepetse chiopsezo cha matenda a nyamakazi pambuyo pake.. Loc
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.
Distal Medial Humeral Locking Plate
Mbale iyi ndi yankho lamkati lopangira ma fractures apakati a distal humerus, omwe amapereka chithandizo kudzera munjira yapakatikati kuti apewe kupunduka kwa varus, komwe nthawi zambiri amagwiritsidwa ntchito pamilandu yosweka ndege.

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.

Plate Fixation Strategie
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.
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.
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.
