Kev phais mob | "Kirschner Wire Tension Band Technique" rau Internal Fixation hauv Kev Kho Mob ntawm Bennett's Fracture

Bennett tus pob txha muaj 1.4% ntawm tes pob txha. Tsis zoo li cov pob txha zoo tib yam ntawm lub hauv paus ntawm cov pob txha metacarpal, kev hloov ntawm Bennett pob txha yog qhov tshwj xeeb. Qhov sib thooj articular nto fragment yog khaws cia nyob rau hauv nws thawj anatomical txoj hauj lwm vim yog rub ntawm oblique metacarpal ligament, thaum lub distal fragment, vim traction ntawm abductor pollicis longus thiab adductor pollicis tendons, dislocates dorsoradially thiab supinates.

Rau kev tshem tawm Bennett cov pob txha, kev kho mob phais feem ntau pom zoo kom tsis txhob ua kom tsis zoo ntawm cov carpometacarpal sib koom tes thiab ntiv tes xoo. Nyob rau hauv cov nqe lus ntawm kev kho mob phais, phaj thiab ntsia hlau fixation tshuab, nrog rau Kirschner hlau sab hauv fixation, yog dav siv nyob rau hauv kev kho mob xyaum. Cov kws tshawb fawb los ntawm Lub Tsev Kho Mob Thib Peb ntawm Hebei tau tshaj tawm cov txheej txheem Kirschner hlau nro band, uas muaj kev cuam tshuam me me los kho Bennett cov pob txha, ua tiav cov txiaj ntsig zoo.

Kauj Ruam 1: Ua ib qho 1.3 cm incision ntawm sab radial ntawm carpometacarpal sib koom ua ke, txiav cov txheej txheem los ntawm txheej kom nthuav tawm thaj chaw, thim rov qab cov abductor pollicis longus mus rau sab ulnar, thiab nthuav tawm sab dorsal ntawm carpometacarpal sib koom.

Kauj ruam 2: Siv phau ntawv traction thiab pronate tus ntiv tes xoo kom txo tau qhov tawg. Ntxig 1 hli Kirschner hlau los ntawm qhov kawg ntawm qhov tawg, 1-1.5 cm deb ntawm carpometacarpal sib koom, txhawm rau txhim kho cov pob txha pob txha. Tom qab Kirschner xaim nkag mus rau cov pob txha tawg, txuas ntxiv nce mus txog 1 cm.

Kauj Ruam 3: Siv ib lub xaim thiab voj nws nyob rau hauv daim duab-yim qauv nyob ib ncig ntawm ob kawg ntawm Kirschner hlau, tom qab ntawd muab nws tso rau hauv qhov chaw.

Cov txheej txheem Kirschner hlau nro band tau siv rau hauv ntau cov pob txha, tab sis rau Bennett cov pob txha, qhov kev txiav me me feem ntau ua rau tsis pom kev thiab ua rau cov txheej txheem nyuaj. Tsis tas li ntawd, yog tias cov pob txha tawg tau tshwm sim, ib qho Kirschner hlau tsis tuaj yeem ua kom cov pob txha zoo sib xws. Nws qhov kev siv tshuaj kho mob yuav raug txwv. Dhau li ntawm cov lus hais saum toj no, kev kho cov hlua khi, kuj tseem muaj Kirschner hlau fixation ua ke nrog cov txheej txheem nro band, uas kuj tau tshaj tawm hauv cov ntaub ntawv.
