InterTAN Intramedullary ntsia thawv

Intertrochanteric hip fractures yog ib qho tshwm sim thiab raug mob hnyav tshwj xeeb tshaj yog rau cov neeg laus.Trochanteric fractures (TF) yog qhov thib ob feem ntau fractures ntawm proximal femur tom qab femoral caj dab pob txha thiab yog qhov tseem ceeb ntawm kev mob thiab kev tuag nyob rau niaj hnub no cov neeg laus.

Los ntawm 2050, tus naj npawb txhua xyoo ntawm pob txha pob txha thoob ntiaj teb tau kwv yees tias yuav dhau 6.3 lab vim yog cov neeg laus laus hauv ntau lub tebchaws sab hnub poob.Hauv Tebchaws Meskas ib leeg, tus naj npawb ntawm cov pob txha pob txha tau kwv yees li ntawm 320,000 ib xyoos mus rau 580,000 los ntawm 2040. Qhov kev thov nce ntxiv no ua rau muaj kev ntxhov siab loj rau kev pabcuam kev noj qab haus huv raws li cov neeg ua haujlwm thiab cov peev txheej xav tau los tswj cov neeg mob no.Hauv Tebchaws Meskas, cov nqi kho mob rau kev tswj hwm pob txha pob txha tau kwv yees ntau dua $ 10 nphom hauv ib xyoos, thaum qhov cuam tshuam rau UK kev pabcuam kev noj qab haus huv kwv yees li $ 2 nphom hauv ib xyoos.Cov nqi no tau tsav tsis yog los ntawm cov nqi ntawm cov txheej txheem phais mob hnyav nkaus xwb tab sis kuj tseem muaj kev saib xyuas tom qab mob hnyav, suav nrog kev kho kom rov zoo.Txawm hais tias kev phais pob txha pob txha yog qhov ua tau zoo, cov neeg mob yuav muaj kev mob hnyav ntawm qhov mob, tsis xis nyob thiab tsis muaj kev txav mus los thaum lawv rov qab los thiab hauv ntau qhov tsis zoo li ua tiav ua ntej pob txha ua haujlwm.Cov kev tshawb fawb tseem qhia tau tias muaj kev sib koom ua ke ntawm pob txha pob txha thiab nce cov neeg tuag nrog 30% kev tuag ntau dua li cov hnub nyoog sib xws nrog thiab tsis muaj pob txha pob txha.Txawm li cas los xij, qee qhov yuav tsum tau ceev faj hauv kev txhais cov ntaub ntawv no, vim tias cov tib neeg uas muaj lub duav pob txha tuaj yeem ua rau muaj kev puas tsuaj ntau dua thiab raug mob hnyav.

Thoob plaws ntiaj teb, qhov xwm txheej ntawm cov pob txha ntawm cov femur proximal yog nce vim muaj kev hloov pauv ntawm cov pej xeem uas ua rau muaj sia nyob ntev dua.

Kev kho mob phais yog lub tswv yim zoo rau kev tswj cov pob txha intertrochanteric vim nws tso cai rau kev kho mob ntxov thiab kev ua haujlwm zoo.

Txhawm rau txo cov teeb meem ntawm lub sijhawm ntev immobilization, kev ua haujlwm ua haujlwm raws sijhawm muab lub suab ruaj khov ntawm cov pob txha thiab kev txav mus rau cov neeg mob thaum ntxov tau dhau los ua cov kev daws teeb meem zoo tshaj plaws rau kev kho cov pob txha no.Ib zaug dynamic hip ntsia hlau (DHS) kev kho sab hauv yog ib qho ntawm cov kev xaiv tseem ceeb tshaj plaws, tab sis nws ua tau zoo nrog qhov tshwm sim ntau dua ntawm kev txhim kho sab hauv tsis ruaj khov rau TF.Tsis tas li ntawd, txoj kev phais no yuav ua rau cov ntshav poob ntau, cov ntaub so ntswg puas tsuaj, thiab ua rau cov neeg mob laus zuj zus tuaj.Yog li ntawd, intramedullary fixation pab kiag li lawm tau ua nrov vim biomechanical zoo nyob rau hauv kev kho mob ntawm unstable TF piv nrog DHS sab hauv fixation.

Lub Intertan Nail siv 2 cephalocervical screws nyob rau hauv ib qho kev sib koom ua ke, qhia tau hais tias muaj kev ruaj ntseg thiab tsis kam mus rau intraoperative thiab postoperative femoral taub hau tig piv nrog cov tsoos intramedullary nailing system.Ib txoj kev tshawb fawb biomechanical tau pom tias Intertan Nail muaj ntau cov txiaj ntsig biomechanical rau kev kho sab hauv ntawm cov pob txha tsis ruaj khov piv nrog cov tsoos intramedullary nailing system Intertan Nail.Qee cov kev tshawb fawb tau qhia tias txoj kev phais mob tau txais txiaj ntsig zoo thiab muaj cov teeb meem tsawg].Kev tshawb fawb biomechanical ntawm Nüchtern et al.qhia tau tias Intertan Nail ua tiav kev ruaj ntseg ntau dua nrog qhov siab dua apex nrug thiab tiv taus qhov siab dua.
