By CAHKev Kho Mob | Sichuan, Suav teb

Rau cov neeg yuav khoom uas nrhiav kev pab cuam MOQ qis thiab ntau yam khoom, Multispecialty Suppliers muab kev pab cuam MOQ qis, kev daws teeb meem logistics kawg, thiab kev yuav khoom ntau pawg, txhawb nqa los ntawm lawv cov kev paub txog kev lag luam thiab kev pabcuam nplua nuj thiab kev nkag siab zoo txog cov qauv khoom tshiab.

Ⅰ. Plaub hom pob txha tawg yog dab tsi?

1. Pob txha pob txha ntawm lub pob txha caj qaum

Pob txha caj dab femoral: Nws yog ib qho tshwm sim rau cov neeg laus uas muaj pob txha osteoporosis thiab tuaj yeem ua rau ischemia thiab necrosis ntawm lub taub hau femoral.

Kev tawg ntawm cov hlab ntsha hauv lub hlwb (intertrochanter): Cov kab tawg nyob nruab nrab ntawm cov hlab ntsha loj dua thiab cov hlab ntsha me dua, nrog rau cov ntshav ntws zoo dua thiab kev kho mob zoo dua.

Cov pob txha tawg subtrochanteric: tshwm sim hauv qab lub trochanter me me, feem ntau yog los ntawm kev raug mob siab, thiab feem ntau xav tau kev phais.

2. Kev tawg ntawm tus ncej femoral

Cov pob txha tawg tshwm sim hauv nruab nrab ntawm lub pob txha femur thiab feem ntau yog los ntawm kev ua phem ncaj qha (piv txwv li, kev sib tsoo tsheb, kev poob), feem ntau nrog kev hloov chaw loj thiab kev puas tsuaj rau cov nqaij mos.

3. Kev tawg ntawm lub pob txha caj qaum sab nraud

Kev tawg ntawm pob txha caj qaum ntawm lub pob txha caj qaum: nyob ze rau ntawm pob qij txha hauv caug, tej zaum yuav cuam tshuam rau qhov chaw ntawm cov pob qij txha, thiab xav tau kev txo qis ntawm lub cev kom rov qab ua haujlwm ntawm cov pob qij txha.

Kev tawg ntawm cov pob txha caj qaum interfemoral: cuam tshuam nrog cov pob txha caj qaum medial thiab sab nraud, qhov sib koom ua ke ntawm lub dav hlau yuav tsum tau soj ntsuam kom tiv thaiv kev mob pob qij txha.

Ⅱ. Yuav tsum ceev faj li cas thaum phais mob rau tes ntawm lub femoral?

Tom qab phais mob, yuav tsum tau ua tib zoo saib xyuas cov hauv qab no: Ua ntej, saib xyuas cov ntshav ntws ntawm qhov phais mob, thiab siv tshuaj tua kab mob kom zoo rau 24 ~ 48 teev tom qab phais mob kom tiv thaiv kev kis kab mob. Qhov phais mob yuav tsum tau hloov tas li, thiab cov kua dej yuav tsum tau muab tshem tawm hauv 24 teev. Qhov thib ob, ua cov haujlwm ntawm lub duav thiab lub hauv caug thiab kev tawm dag zog sai li sai tau tom qab phais mob. Cov rau tes hauv lub hauv caug rau cov pob txha tawg ntawm lub femoral suav nrog cov rau tes uas yuav tsum tau ntsia los ntawm lub duav lossis lub hauv caug, uas yuav ua rau muaj kev puas tsuaj rau cov nqaij mos nyob ib puag ncig cov pob qij txha thiab yuav ua rau muaj ntshav sib sau ua ke hauv cov pob qij txha. Yog li ntawd, nws raug pom zoo kom ua kom cov pob qij txha txav tau sai tom qab phais mob kom tiv thaiv cov teeb meem xws li kev sib txuas ntawm cov pob qij txha, thiab tseem txo qhov kev tsim cov hlab ntsha tob hauv cov ceg qis. Qhov thib peb, nws tsis raug pom zoo kom nqa cov hnyav sai dhau tom qab phais mob, thiab nws yog qhov tsim nyog los saib xyuas cov duab X-ray tas li kom nkag siab txog kev loj hlob thiab kev kho ntawm cov pob txha tawg, thiab txhawb kev kho pob txha tawg kom zoo los ntawm cov tshuaj.

III. Qhov txawv ntawm PFN A thiab A2 yog dab tsi?

PFN-A thiab A2 yog ob lub tswv yim sib txawv kiag li, qhov qub yog lub cuab yeej kho sab hauv rau kev kho cov pob txha tawg ntawm femoral intertrochanteric (cov ntsia hlau tiv thaiv kev tig proximal femoral intramedullary), thiab qhov kawg yog kev faib tawm ntawm cov pob txha tawg ntawm femoral intertrochanteric hauv AO typing system.

PFN-A yog ib lub cuab yeej phais kho sab hauv tshwj xeeb, uas sawv cev rau "Proximal Femoral Nail Anti-rotation". Nws yog ib lub tshuab ntsia hlau intramedullary uas kho cov pob txha tawg los ntawm kev ntxig lawv rau hauv lub femoral medullary cavity, nrog rau cov yam ntxwv ntawm kev tiv thaiv kev tig thiab kev kho kom ruaj khov, thiab feem ntau yog siv rau kev kho cov pob txha tawg intertrochanteric ntawm femoral femoral nrog AO hom A1, A2, A3 thiab cov pob txha tawg subtrochanteric siab.

A2 yog ib hom kev piav qhia txog kev tawg pob txha ntawm cov pob txha caj qaum hauv AO classification system thiab raug cais ua qhov tawg pob txha tsis ruaj khov. Raws li AO classification, hom A2 tawg pob txha yog tus cwj pwm los ntawm ib txoj kab tawg pob txha hla thaj tsam trochanteric thiab kev tawg ntawm lub medial cortex hauv tsawg kawg yog ob qhov chaw nrog ntau cov blocks tawg pob txha. Nws raug faib ua:

Hom A2.1: Muaj qhov tawg nruab nrab ntawm cov trochanters.

Hom A2.2: Muaj ntau qhov thaiv pob txha nruab nrab ntawm cov trochanters.

Hom A2.3: Cov kab tawg ntev tshaj 1cm hauv qab lub trochanter me me

Hauv ntej, PFN-A yog ib qho cuab yeej kho mob thiab A2 yog hom pob txha tawg. Hauv kev kho mob, cov kws kho mob yuav xaiv txoj kev kho kom zoo raws li AO kev faib tawm ntawm tus neeg mob pob txha tawg (xws li hom A2), thiab PFN-A yog ib qho ntawm cov txheej txheem phais mob rau kev kho cov pob txha tawg tsis ruaj khov xws li hom A2.
