Qhov sib txawv tseem ceeb ntawm cortical thiab tshem tawm cov ntsia hlau yog tias cov ntsia hlau cortical muaj lub suab zoo thaum cov ntsia hlau tshem tawm muaj lub suab ntxhib.
Nyob rau hauv kev phais orthopedic sib txawv, cov ntsia hlau sib txawv yog siv los kho cov pob txha. Cov ntsia hlau no khaws cov pob txha puas ua ke txhawm rau txhawm rau txhim kho txoj hauv kev zoo thiab muab kev ruaj ntseg rau lub cev hauv cov ntsiab lus ntawm lub cev thiab kev txav. Cov ntsia hlau tsim los rau cov pob txha cortical thiab cov pob txha tshem tawm yog ob hom tseem ceeb (xov hom) ntawm cov ntsia hlau phais. Ob lub hau ntswj yog tsim raws li cov qauv kev kho mob nrog kev siv cov khoom zoo xws li stainless hlau 316L lossis titanium.
Dab tsi yog Cortical Screw?
A cortical ntsia hlau yog ib hom ntawm cov ntsia hlau ntsia hlau siv los ntawm cov kws phais orthopedic txhawm rau txhawm rau cov pob txha thiab lwm yam khoom siv orthopedic rau cov pob txha cortical. Hauv lwm lo lus, cov ntsia hlau no tau koom nrog kho cov pob txha puas vim kev raug mob thiab raug mob. Cortical screws siv nyob rau hauv xws li kev phais yog qib kho mob. Cov ntsia hlau no yog cov ntsia hlau feem ntau siv hauv cov pob txha raug mob.
Daim duab 01: Cortical Screw
Cortical screws muaj lub taub me me nrog lub suab zoo. Cov qauv xov ntawm cortical ntsia hlau yog ib txoj xov tag nrho. Qhov ntsuas ntawm lub cortical ntsia hlau txawv ntawm 2 hli mus rau 4.5 hli. Qhov ntev ntawm cov ntsia hlau no txawv ntawm 8 hli mus rau 60 hli, nyob ntawm qhov yuav tsum tau ua. Feem ntau, lub cortical ntsia hlau yog muab kev koom tes nyob rau hauv lub fixation ntawm zoo xws li txoj kab uas hla tsis-locking daim hlau. Cov qauv xov yog tiav threaded los yog ib nrab threaded.
Dab tsi yog Qhov Ntsia Hlau Tshem Tawm?
Ib tus ntsia hlau tshem tawm yog ib yam ntawm cov ntsia hlau ntsia hlau siv los ntawm cov kws phais orthopedic txhawm rau txhawm rau pob txha daim hlau thiab lwm yam khoom siv orthopedic rau cov pob txha. Cov ntsia hlau no yog cov ntsia hlau kho mob uas tsim los ntawm stainless hlau 316L lossis titanium. Lub luag haujlwm ntawm cov ntsia hlau tshem tawm yog tsim kom muaj kev sib tshuam hauv cov chaw sib koom ua ke, xws li hauv tibia lub taub hau tawg.
Daim duab 02: Ncua tseg Screw
Tus tsim ntawm kev tshem tawm cov ntsia hlau ua kom zoo rau kev txhim kho hauv cov pob txha metaphysical ib puag ncig. Cancellous screws muaj lub suab ntxhib. Qhov ntsuas ntawm lub cortical ntsia hlau txawv ntawm 2 hli mus rau 4.5 hli. Cov qauv xov yog tiav threaded los yog ib nrab threaded. Lawv yog cov tsis-tus kheej-tapping screws. Qhov tseem ceeb ntawm cov ntsia hlau no yog tias lawv yuav tsum tsis txhob rub txhua txoj hauv kev, tsuas yog thawj ob peb lub lem, vim tias lawv ua haujlwm zoo dua thaum lawv txiav lawv tus kheej txoj hauv kev rau hauv cov pob txha.
Dab tsi zoo sib xws ntawm Cortical thiab Cancellous Ntsia Hlau?
- Cortical thiab tshem tawm cov ntsia hlau yog ob hom kev phais ntsia hlau.
- Ob qhov ntsia hlau yog koom nrog kev phais pob txha.
- Ob lub cortical thiab tshem tawm cov ntsia hlau ua kom cov pob txha ua ke.
- Lawv yog tsim los ntawm SS 316L lossis titanium.
- Ntxiv mus, cov qauv ntsia hlau yog nyob rau hauv tag nrho threaded los yog ib nrab threaded hom.
Qhov txawv ntawm Cortical thiab Cancellous Ntsia Hlau yog dab tsi?
A cortical ntsia hlau muaj lub suab zoo thaum lub qhov ntsia hlau tshem tawm muaj lub suab ntxhib. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cortical thiab cancellous ntsia hlau. Cov qauv xov loj yog tsim los ntawm cortical screws whereas me me xov qauv yog tsim los ntawm tshem tawm screws.
Cov hauv qab no qhia txog qhov sib txawv ntawm cortical thiab tshem tawm cov ntsia hlau hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Cortical vs Cancellous Screw
Cov ntsia hlau cortical muaj lub suab zoo thaum cov ntsia hlau tshem tawm muaj lub suab ntxhib. Lub luag haujlwm ntawm cov ntsia hlau cortical yog tsim cov kev sib tshuam hauv qhov chaw xws li txheej txheej ntawm cov pob txha ntev ua rau lub taub hau thiab sab hauv ntawm cov pob txha trabecular ntawm qhov sib thooj thiab qhov kawg ntawm cov pob txha pob txha. Lub luag haujlwm ntawm cov ntsia hlau tshem tawm yog los tsim cov kev sib tshuam sib txuas hauv cov chaw sib koom ua ke, xws li hauv qhov tibia lub taub hau tawg. Ob lub screws no yog tsim nyob rau hauv cov qauv kev kho mob nrog kev siv cov khoom zoo xws li stainless hlau 316L los yog titanium. Yog li, qhov no qhia txog qhov sib txawv ntawm cortical thiab tshem tawm cov ntsia hlau.
