Lub hom phiaj tseem ceeb ntawm kev txhim kho pob txha pob txha yog txhawm rau txhim kho cov pob txha pob txha, ua kom cov pob txha raug mob sai sai, thiab rov qab mus sai sai thiab ua haujlwm tag nrho ntawm qhov raug mob sab nraud.

External fixation yog ib txoj kev siv los kho cov pob txha tawg loj. Hom kev kho mob orthopedic no suav nrog kev ruaj ntseg pob txha nrog cov cuab yeej tshwj xeeb hu ua fixator, uas yog sab nraud rau lub cev. Siv cov pob txha tshwj xeeb (feem ntau hu ua pins) uas dhau los ntawm daim tawv nqaij thiab cov leeg, lub fixator txuas nrog cov pob txha puas kom nws nyob rau hauv kev sib raug zoo raws li nws kho.

Lub fixator sab nraud siv rau dab tsi?

Ib qho cuab yeej fixation sab nraud tuaj yeem siv los ua kom cov pob txha tawg kom ruaj khov thiab ua kom zoo. Cov cuab yeej tuaj yeem hloov kho sab nraud kom ntseeg tau tias cov pob txha nyob hauv qhov chaw zoo thaum lub sijhawm kho. Cov cuab yeej no feem ntau yog siv rau hauv cov menyuam yaus thiab thaum cov tawv nqaij ntawm cov pob txha puas lawm.

Dab tsi yog hom kev kho sab nraud?

Muaj peb yam yooj yim ntawm cov fixators sab nraud: tus qauv uniplanar fixator, nplhaib fixator, thiab hybrid fixator.

Cov khoom siv ntau yam siv rau kev kho sab hauv yog kwv yees muab faib ua ob peb pawg loj: xov hlau, pins thiab screws, daim hlau, thiab cov ntsia hlau intramedullary lossis rods.

Staples thiab clamps kuj siv qee zaus rau osteotomy lossis pob txha fixation. Autogenous pob txha grafts, allografts, thiab pob txha hloov pauv pob txha yog nquag siv rau kev kho pob txha tsis xws luag ntawm ntau yam ua rau. Rau cov kab mob sib kis nrog rau kev kho pob txha kab mob, cov hlaws tshuaj tua kab mob feem ntau siv.

Dynamic Axial Proximal Femoral Fragment Sab Nraud Fixator: Kev Pom Zoo

Hip fractures yog ib qho teeb meem ntawm orthopedic, tshwj xeeb tshaj yog nyob rau hauv cov neeg laus. Cov pob txha no tuaj yeem ua rau muaj mob hnyav thiab tuag taus, thiab lawv txoj kev tswj hwm feem ntau nyuaj. Ib qho ntawm cov txheej txheem siv los tswj cov pob txha pob txha yog cov dynamic axial proximal femoral fragment sab nraud fixator (DAPFFEF). Hauv tsab xov xwm no, peb yuav muab cov ntsiab lus dav dav ntawm DAPFFEF, suav nrog nws cov lus qhia, txheej txheem, teeb meem, thiab cov txiaj ntsig.

Taw qhia

Cov pob txha pob txha yog ib qho teeb meem loj rau pej xeem kev noj qab haus huv, nrog kwv yees li 1.6 lab tus neeg mob tshwm sim thoob ntiaj teb txhua xyoo. Cov pob txha no muaj feem cuam tshuam nrog kev mob siab thiab kev tuag, tshwj xeeb tshaj yog cov neeg laus. Kev tswj cov pob txha pob txha yog feem ntau nyuaj, thiab ntau yam kev phais siv los tswj lawv. Ib qho ntawm cov txheej txheem no yog dynamic axial proximal femoral fragment sab nraud fixator (DAPFFEF).

Anatomy ntawm lub Hip

Ua ntej sib tham txog DAPFFEF, nws yog ib qho tseem ceeb kom nkag siab txog lub cev ntawm lub duav. Lub hauv siab pob qij txha yog pob-thiab-socket sib koom ua ke, muaj cov acetabulum ntawm lub plab thiab lub taub hau femoral. Lub caj dab femoral txuas lub taub hau femoral mus rau femoral ncej. Lub proximal femur yog ib feem ntawm lub femur uas nyob ze tshaj plaws ntawm lub duav pob qij txha.

Dab tsi yog Dynamic Axial Proximal Femoral Fragment External Fixator?

Lub dynamic axial proximal femoral fragment external fixator (DAPFFEF) yog ib qho cuab yeej siv los txhim kho cov pob txha ntawm cov femur proximal. Cov cuab yeej muaj ib txheej ntawm cov pins los yog cov ntsia hlau uas tau muab tso rau hauv cov femur proximal thiab txuas nrog rau sab nraud. Lub thav duab muab kev ruaj ntseg rau cov pob txha tawg, cia nws kho.

Indications rau DAPFFEF

DAPFFEF yog siv los kho cov pob txha ntawm qhov sib thooj ntawm lub femur, nrog rau cov pob txha pob txha, cov pob txha intertrochanteric, thiab cov pob txha subtrochanteric. Nws kuj yog siv los kho cov tsis sib koom tes thiab malunions ntawm proximal femur.

Cov txheej txheem ntawm DAPFFEF

Cov txheej txheem ntawm DAPFFEF suav nrog kev ntxig pins lossis cov ntsia hlau rau hauv qhov sib thooj femur, uas txuas nrog rau sab nraud. Cov pins lossis screws tau muab tso rau hauv ib txoj hauv kev uas tso cai rau lawv los ua ib lub caj npab, muab dynamic compression rau cov pob txha tawg. Lub thav duab yog kho kom ua tiav qib siab ntawm compression.

Qhov zoo ntawm DAPFFEF

Qhov zoo ntawm DAPFFEF suav nrog nws lub peev xwm los muab kev txhim kho ruaj khov ntawm qhov sib thooj femur, nws lub peev xwm los muab kev sib zog ua kom zoo rau cov pob txha tawg, thiab nws muaj peev xwm tso cai rau qhov hnyav thaum ntxov. Cov xwm txheej no tuaj yeem ua rau cov txiaj ntsig tau zoo dua qub thiab lub sijhawm rov qab sai dua rau cov neeg mob.

Cov teeb meem ntawm DAPFFEF

Cov teeb meem ntawm DAPFFEF muaj xws li kab mob kis kab mob, tsis muaj kev sib koom ua ke, malunion, poob ntawm kev txo qis, thiab cog tsis ua haujlwm. Cov teeb meem no tuaj yeem tswj hwm nrog kev kho kom tsim nyog, suav nrog tshuaj tua kab mob, kho kev phais, thiab tshem tawm cov fixator.

Cov txiaj ntsig ntawm DAPFFEF

Cov txiaj ntsig ntawm DAPFFEF tau kawm hauv ntau qhov kev sim tshuaj. Cov kev sim no tau pom tias DAPFFEF tuaj yeem muab kev kho kom ruaj khov ntawm cov femur proximal, tso cai rau kev hnyav thaum ntxov thiab txhim kho cov txiaj ntsig rau cov neeg mob.

Xaus

Dynamic axial proximal femoral fragment external fixator (DAPFFEF) yog cov txheej txheem phais siv los tswj cov pob txha ntawm cov femur proximal. Nws muab ruaj khov kho thiab dynamic compression rau cov pob txha tawg, tso cai rau kev hnyav thaum ntxov thiab txhim kho cov txiaj ntsig rau cov neeg mob. Cov teeb meem tuaj yeem tshwm sim, tab sis lawv tuaj yeem tswj tau nrog kev kho kom tsim nyog.
