Dab tsi yog cov thev naus laus zis ntawmPfna Nail?
PFNA (Proximal Femoral Nail Anti-rotation)Cov ntsia hlau ntawm lub pob txha ncej puab yog ib qho system kho kom ruaj khov sab hauv uas tsis muaj kev cuam tshuam ntau uas tsim tshwj xeeb rau kev tawg pob txha ntawm cov pob txha caj qaum.
Cov txiaj ntsig ntawmCov ntsia hlau Femur Intramedullary?
Kev Ruaj Ntseg Biomechanical
Cov rau tes hauv qab medullary siv ib txoj kev tsim hniav helical xwb. Los ntawm kev ua kom cov pob txha cancellous nruj, cov hniav muab kev ruaj khov tiv thaiv kev tig thiab lub kaum sab xis, ua rau nws tsim nyog rau cov pob txha tawg hauv cov neeg laus. Cov kev tshawb fawb hauv tsev kho mob tau qhia tias cov hniav helical khaws cov pob txha thiab ua rau cov pob txha muaj zog, yog li txo qhov kev pheej hmoo ntawm kev ua tsis tiav tom qab phais.
Cov Yam Ntxim Saib Xyuas Kev Phais Mob Uas Tsis Muaj Kev Cuam Tshuam Ntau
Kev phais me me: Tsuas yog xav tau kev phais sab nraud ntev li ntawm 5 cm xwb; qhov chaw tawg tsis pom, uas txo qhov kev raug mob ntawm cov nqaij mos.
Lub sijhawm ua haujlwm luv luv: Cov txheej txheem tuaj yeem ua tiav hauv 30 txog 60 feeb qhov nruab nrab, luv dua 30% piv rau cov txheej txheem kho phaj-ntsia hlau ib txwm muaj.
Kev poob ntshav tsawg: Kev poob ntshav thaum phais mob raug tswj ntawm 50-100 mL, tsawg dua li ntawm kev phais qhib.
Kev Txhawb Nqa Rau Kev Kho Kom Rov Zoo Sai
Cov neeg mob tuaj yeem sawv ntawm txaj mus taug kev tau 3 txog 5 hnub tom qab phais. Raws li cov ntaub ntawv kho mob ntawm ntau dua 200 tus neeg mob, tus nqi ciaj sia nyob 5 xyoos tshaj 80%, ua rau txoj kev no zoo tagnrho rau cov neeg mob laus uas muaj ntau yam kab mob sib koom ua ke.
