Sab nraub qaum muaj xws li sab nraud ntawm lub metaphysis ntawm humerus, lateral epicondyle, thiab lateral condyle, nrog rau lub capitulum ntawm humerus.
Coronoid Fossa thiab Olecranon Fossa
Nyob nruab nrab ntawm ob kab yog lub anterior coronoid fossa thiab posterior olecranon fossa.
Mechanism of Injury in Distal Humerus Fractures
Yog vim li cas lub distal humerus yog fractures?
Raws li ib feem tseem ceeb ntawm lub luj tshib, cov pob txha humerus feem ntau tshwm sim los ntawm 'txoj kev raug mob' (xws li lub caij nplooj zeeg tsaws ntawm lub luj tshib) lossis 'kev raug mob tsis ncaj' (xws li kev sib tw lossis kev cuam tshuam).
· Muaj zog contraction ntawm internal rotator cov leeg
· Muaj zog contraction ntawm lub luj tshib flexor cov leeg
-High-Energy Trauma
Sab nraud quab yuam xws li kev sib tsoo tsheb los yog ntog los ntawm qhov siab tuaj yeem ua rau muaj kev puas tsuaj los yog cuam tshuam rau cov pob txha.
- C3: Comminuted intra-articular fractures, qhov nyuaj tshaj plaws los kho; ruaj khov kho yog xav tau los txo txoj kev pheej hmoo ntawm kev mob caj dab tom qab..
Qhov tseem ceeb ntawm Classification:
Kev faib tawm AO qhia meej txog qhov hnyav ntawm qhov tawg thiab muab kev taw qhia rau kev xaiv phaj (xws li, ib leeg thiab ob daim hlau, xauv ntsia hlau tsim) kom ntseeg tau tias ob qho tib si fixation lub zog thiab kev sib npaug ntawm cov roj ntsha.
Ua raws li AO lub tswv yim: 'Anatomical txo, ruaj khov kho, thiab ua haujlwm thaum ntxov.'
High-Energy Trauma
Sab nraud quab yuam xws li kev sib tsoo tsheb los yog ntog los ntawm qhov siab tuaj yeem ua rau muaj kev puas tsuaj los yog cuam tshuam rau cov pob txha.
Txoj Cai Kho Mob
Anatomical txo
ruaj khov fixation
Kev ua haujlwm thaum ntxov
Kev phais mob
Articular tshem tawm> 2mm
Qhib pob txha
Combined neurovascular raug mob
Ua tsis tiav ntawm kev saib xyuas kev kho mob
Phaj Fixation Strategie
Dual Phaj Technique
Haum rau hom C tawg. Kev kho los ntawm ob qho tib si medial (piv txwv li, anatomical locking phaj) thiab lateral (piv txwv li, parallel phaj) sab muab 3D stability thiab txo qhov kev pheej hmoo ntawm postoperative rotational deformity.
Ib Plate Technique
Siv rau hom A thiab ib nrab hom B puas. Pre-contoured daim hlau conforming rau distal humerus anatomy txo cov nqaij mos dissection.
Yam tsawg kawg nkaus Invasive Approach
Ua ke nrog percutaneous ntsia hlau tso kom txo tau cov kab mob thiab khaws cia cov ntshav periosteal.
Kev txo qis hauv lub cev khaws cia lub luj tshib sib koom ua ke mus rau qhov loj tshaj plaws, txo cov teeb meem xws li nonunion lossis malunion.
Customized Tsim
Daim hlau zoo li rau cov pob txha pob txha tshwj xeeb (xws li, intercondylar ridge support plates) optimize force transmission and accelerate pob txha kho.
Kev paub txog tus kheej ntawm kev tswj hwm tag nrho.
Lub vev xaib no siv cov ncuav qab zib thiab cov thev naus laus zis zoo sib xws ('cookies'). Raws li koj qhov kev pom zoo, yuav siv cov ncuav qab zib tsom xam los taug qab cov ntsiab lus twg koj nyiam, thiab cov ncuav qab zib ua lag luam los nthuav tawm cov paj laum raws li kev tshaj tawm.
