Yuav Ua Li Cas Kho Distal Humerus Fractures Siv Daim Hlau?

Displaced comminuted fractures ntawm lub distal humerus nyob rau hauv cov neeg laus yog ib qho teeb meem nyuaj vim lub complex anatomy ntawm lub luj tshib sib koom, me me fractures, thiab tsawg npaum li cas ntawm cov pob txha subchondral. Lub lateral thiab medial kab ntawm lub distal humerus tsim ib daim duab peb sab ruaj khov. Qhov kev ruaj ntseg daim duab peb sab no cuam tshuam tom qab distal humerus fractures, tshwj xeeb tshaj yog nyuaj AO C-hom pob txha.

Keeb kwm

Nyob rau hauv AO Internal Fixation Technique phau ntawv luam tawm nyob rau hauv 1979, rau comminuted fractures ntawm lub distal humerus, pab pawg neeg AO pom zoo kom cov phiaj yuav tsum tau muab tso rau 90 ° rau ib leeg, ib tug nruab nrab los yog lateral thiab ib tug posterior (1).

Cov kauj ruam technical (AO cov hauv paus ntsiab lus rau kev kho pob txha)

a: Reconstruction ntawm trochlear thiab capitellum.

bc: Tom qab txo peb cov pob txha pob txha, laum Kirschner hlau nyob rau hauv qhov kev taw qhia. Lub Kirschner hlau tuaj yeem siv los ua cov ntawv qhia xaim rau 3.5mm cannulated ntsia hlau, lossis cov ntsia hlau tuaj yeem muab tso rau tib lub sijhawm rau Kirschner hlau.

d: Siv ib ntus Kirschner xaim los txuas cov pob txha pob txha mus rau lub taub hau humeral

e: Txhawm rau txhim kho cov kab mob sib kis mus rau lub humerus, lub cev LCP yuav tsum xub muab tso rau ntawm qhov chaw tom qab ntawm lub humerus, thiab lub phaj tuaj yeem muab tso rau hauv qab lub capitulum yam tsis muaj pob txha mos. Lub medial anatomical LCP tuaj yeem muab tso rau ntawm qhov nruab nrab ntawm lub humerus los txhim kho kev ruaj ntseg. Rau cov pob txha loj heev los yog metaphyseal comminution loj heev, kev tso ob LCPs ntawm 90 ° rau ib leeg yog pom zoo, vim qhov kev teeb tsa no muab kev ruaj ntseg biomechanical zoo dua. Kev saib xyuas yuav tsum tau ua kom tsis txhob nkag mus rau qhov sib koom ua ke thaum siv lub kaum ntse ntse stabilization screws.

Kev sib piv ntawm parallel thiab ntsug steel daim hlau

Nyob rau hauv 1995 Mechanics Study Sib piv Dual Phaj rau Kev Kho Mob Distal Humeral Fractures, cov teebmeem ntawm rau lub phaj qhov chaw tau muab piv (A, dual posterior phaj; B, posterior ulnar phaj, lateral rau radial phaj; C, medial thiab lateral phaj; D, medial mus rau lub phaj ulnar, posterior rau cov qauv ntawm lub phaj thiab radial plates; F, tus qauv ntawm cov pob txha loj heev nrog cov ntsia hlau nruab nrab thiab sab nraud), taw qhia tias ntau cov pob txha tuaj yeem kho nrog ob daim hlau hauv ntau qhov chaw kho mob, tab sis rau kev puas tsuaj loj heev, txoj kev tshawb fawb no xaus lus tias kev kho cov phaj nruab nrab nrog cov ntsia hlau kho tau zoo txhim kho qhov tawv thiab lub zog kawg (3).

Ata C (4) thiab al qhia tau hais tias lub phaj ntsug nrog lub phaj posterolateral ntxiv rau plaub 2.7 hli distal screws muaj qhov ruaj khov zoo ib yam li cov phaj sib luag hauv kev kho mob ntawm cov pob qij txha ntawm lub distal humerus. Cov neeg mob tsis xis nyob vim yog khaus ntawm daim tawv nqaij ntawm lub phaj sab nraud, tshwj xeeb tshaj yog cov neeg laus nyias thiab cov neeg laus, tuaj yeem raug tshem tawm nrog cov phaj posterolateral.
