Rau cov neeg yuav khoom nrhiav cov MOQ qis thiab cov khoom lag luam siab, Multispecialty Suppliers muab MOQ qis customization, kawg-rau-kawg logistics kev daws teeb meem, thiab ntau yam kev yuav khoom, txhawb nqa los ntawm lawv cov kev lag luam nplua nuj thiab kev pabcuam thiab kev nkag siab zoo ntawm cov khoom lag luam tawm tshiab.
I.Dab tsi yog qhov fixation sab nraud?
Feem ntau sab nrauv fixators muaj xws li plaster splints thiab me me splints. Nruam traction (xws li pob txha traction thiab daim tawv nqaij traction) kuj muaj kev ua haujlwm ntawm kev txo qis, nres, thiab kho qhov deformities, thiab kuj yog ib hom kev kho sab nraud. Tsis tas li ntawd, sab nraud pinning fixation, uas yuav tsum tau tho cov pob txha xaus nrog steel koob thiab txuas sab nraud stents, kuj yog ib daim ntawv ntawm sab nrauv fixation. Nws yog tsuas yog siv rau cov pob txha qhib loj heev thiab cov ntaub so ntswg loj heev contusions, qhov twg sab nrauv fixation tsis tau thiab phais sab hauv fixation yog nyuaj.
Lub fixator sab nraud yog ib qho cuab yeej siv los kho cov ceg tawv sab nraud. Nws tuav cov ceg ntoo hauv qhov xav tau kho kom yooj yim kho cov pob txha thiab lwm cov ntaub so ntswg. Lub hom phiaj ntawm lub fixator sab nraud yog kom muaj ib txoj hauj lwm los pab txhawb kev kho cov pob txha thiab lwm cov ntaub so ntswg.
II.Qhov txheej txheem rau kev kho sab nraud yog dab tsi?
External fixation yog ib txoj kev orthopedic siv los kho cov pob txha mob xws li pob txha thiab dislocations. Nov yog cov ntsiab lus luv luv:
Fracture Reduction:
Kev txo qis suav nrog traction thiab phau ntawv kev sib hloov los kho pelvic displacements. Rau cov teeb meem sacroiliac sib koom ua ke, tus kws phais thawb lub ilium mus rau ko taw thiab txha nraub qaum. Cov pob txha traction yog ua los ntawm kev ntxig ib rab koob rau hauv femoral condyle. Hauv cov xwm txheej tsis muaj xwm txheej ceev, qhov qis qis qis nrog 15-20 kg hnyav yog siv ua ntej. Tom qab txo qis, siv lub pelvic sab nraud fixator, nrog rau 10 kg traction rau 4-6 lub lis piam. Rau lub nplhaib sab hauv pob txha uas tsis muaj hemipelvic dislocation, tsuas yog xav tau ib qho kev kho sab nraud, tsis yog qis qis qis.
Needling:
Txheeb xyuas cov pob txha thaj chaw zoo li lub iliac crest thiab anterior superior iliac qaum. Kirschner xov hlau tau muab tso rau hauv percutaneously nyob rau sab iliac phab ntsa los txiav txim qhov inclination ntawm iliac crest. Fixation pins yog muab tso rau ntawm lub puab thiab sab iliac daim hlau. Peb 3mm xov hlau yog muab tso rau hauv ib qho kab sib txuas nrog txhua lub iliac crest. Ib qho 5 hli incision yog ua 2 cm posterior rau anterior superior iliac qaum. Pins tau muab tso rau nruab nrab ntawm lub iliac crest mus rau hauv lub medullary kab noj hniav, angled 15 ° -20 ° rau lub dav hlau sagittal, taw rau nruab nrab thiab downward, thiab ruaj ntseg li 5-6 cm tob.
