Kev Phais Mob | "Kirschner Wire Tension Band Technique" rau Kev Kho Sab Hauv Hauv Kev Kho Mob Bennett's Fracture

Qhov pob txha tawg ntawm Bennett suav txog 1.4% ntawm cov pob txha tawg tes. Tsis zoo li cov pob txha tawg ib txwm muaj ntawm lub hauv paus ntawm cov pob txha metacarpal, qhov kev hloov chaw ntawm qhov pob txha tawg ntawm Bennett yog qhov tshwj xeeb heev. Qhov seem ntawm qhov chaw ntawm cov pob txha caj qaum tseem nyob hauv nws qhov chaw qub vim yog qhov rub ntawm oblique metacarpal ligament, thaum qhov seem distal, vim yog qhov traction ntawm abductor pollicis longus thiab adductor pollicis tendons, dislocates dorsoradialy thiab supinates.

Rau cov pob txha tawg Bennett uas raug tshem tawm, kev phais mob feem ntau raug pom zoo kom tsis txhob ua rau lub pob qij txha carpometacarpal thiab tus ntiv tes xoo tsis ua haujlwm zoo. Hais txog cov txheej txheem phais mob, cov phaj thiab cov ntsia hlau kho, nrog rau Kirschner hlau kho sab hauv, yog siv dav hauv kev kho mob. Cov kws tshawb fawb los ntawm Tsev Kho Mob Thib Peb ntawm Hebei tau tawm tswv yim txog Kirschner hlau nruj band txheej txheem, uas cuam tshuam nrog kev phais me me kom kho Bennett cov pob txha tawg, ua tiav cov txiaj ntsig zoo.

Kauj Ruam 1: Ua ib qho kev txiav 1.3 cm rau sab radial ntawm lub pob qij txha carpometacarpal, txiav ib txheej dhau ib txheej kom pom thaj chaw ntawd, rub lub pob qij txha abductor pollicis longus mus rau sab ulnar, thiab qhia sab dorsal ntawm lub pob qij txha carpometacarpal.

Kauj Ruam 2: Siv tes rub thiab rub tus ntiv tes xoo kom txo qhov tawg. Ntxig ib txoj hlua Kirschner 1 hli hla qhov kawg ntawm qhov tawg, 1-1.5 cm ntawm qhov sib koom ua ke carpometacarpal, los kho qhov tawg pob txha proximal. Tom qab txoj hlua Kirschner nkag mus rau hauv qhov tawg pob txha, txuas ntxiv mus txog 1 cm.

Kauj Ruam 3: Siv ib txoj hlua thiab khi nws ua ib daim duab yim ncig ob qho kawg ntawm txoj hlua Kirschner, tom qab ntawd khi nws rau hauv qhov chaw.

Cov txheej txheem siv hlau Kirschner tension band tau siv rau ntau qhov pob txha tawg, tab sis rau Bennett's fractures, qhov kev phais me me feem ntau ua rau pom tsis meej thiab ua rau cov txheej txheem nyuaj. Tsis tas li ntawd, yog tias qhov pob txha tawg raug comminuted, ib qho hlau Kirschner yuav tsis ua kom cov pob txha proximal ruaj khov. Nws cov kev siv tau hauv kev kho mob yuav raug txwv. Dhau li ntawm txoj kev kho tension band uas tau hais los saum toj no, kuj tseem muaj Kirschner wire fixation ua ke nrog cov txheej txheem tension band, uas kuj tau tshaj tawm hauv cov ntaub ntawv.
