Cancellous Screw: Ib qho kev piav qhia ntawm kev siv, kev qhia, thiab cov txheej txheem
Taw qhia
Cancellous screws yog ib hom orthopedic ntsia hlau siv los kho cov pob txha tawg los yog grafts hauv kev kho cov pob txha, tsis koom nrog, thiab lwm yam kev raug mob pob txha. Cov ntsia hlau no tau siv dav hauv kev phais orthopedic vim lawv cov biocompatibility, yooj yim ntawm kev ntxig, thiab cov khoom zoo heev. Hauv tsab xov xwm no, peb yuav tham txog cov lus qhia, cov tswv yim, thiab cov txiaj ntsig ntawm kev siv cov ntsia hlau tshem tawm hauv kev phais orthopedic.
Anatomy thiab Mechanical Properties of Cancellous Screw
Cancellous screws yog ua los ntawm titanium los yog stainless hlau thiab muaj ib tug threaded ncej thiab ib tug tapered taub. Cov xov ntawm tus ncej muab kev yuav khoom zoo heev hauv cov pob txha tshem tawm thiab tiv thaiv kev rub tawm, thaum lub taub hau ua kom yooj yim nkag mus yam tsis muaj kev puas tsuaj rau cov ntaub so ntswg. Cov ntsia hlau tuaj ntawm qhov sib txawv thiab qhov ntev kom haum rau cov pob txha sib txawv thiab cov qauv tawg. Cov khoom siv ntawm cov ntsia hlau tshem tawm yog nyob ntawm cov khoom siv, txoj kab uas hla, ntev, thiab xov tsim. Kev siv txoj kab uas hla loj dua thiab ntev dua screws ua rau kom lub zog tuav thiab ruaj khov, thaum siv cov kab me me thiab cov ntsia hlau luv luv yuav txo tau qhov kev pheej hmoo ntawm overdrilling thiab ntsia hlau tsiv teb tsaws.
Indications rau Cancellous Screw Fixation
Cancellous screws yog qhia rau ntau yam kev mob orthopedic, suav nrog:
Kev puas tsuaj ntawm cov pob txha ntev, xws li femur, tibia, thiab humerus
Kev puas tsuaj ntawm cov pob txha me, xws li dab teg, pob taws, thiab ko taw
Cov koom haum tsis sib koom ua ke thiab ncua kev koom ua ke ntawm kev tawg
Osteotomies, xws li kho pob txha txiav rau deformity los yog malalignment
Arthrodesis, xws li fusion ntawm pob taws, dab teg, lossis txha nraub qaum
Pob txha graft fixation, xws li nyob rau hauv spinal fusion los yog pob txha reconstruction
Cov txheej txheem rau Cancellous Screw Fixation
Cov txheej txheem ntawm kev tshem tawm cov ntsia hlau yog nyob ntawm qhov qhia tshwj xeeb thiab cov qauv tawg. Cov ntsiab cai dav dav ntawm cov ntsia hlau ntxig muaj xws li:
Kev ua kom zoo ntawm tus neeg mob thiab kev txheeb xyuas qhov chaw tawg
Tsim ib tug pilot qhov uas siv ib tug xyaum me ntsis los yog ib tug kais
Kev ntsuas ntawm cov ntsia hlau ntev thiab txoj kab uas hla
Ntxig cov ntsia hlau siv lub hau ntswj los yog lub zog xyaum
Kev txheeb xyuas ntawm cov ntsia hlau txoj hauj lwm thiab qhov tob uas siv cov qauv duab, xws li fluoroscopy lossis X-ray
Cov yam tseem ceeb uas cuam tshuam rau kev ua tiav ntawm kev tshem tawm cov ntsia hlau ntsia hlau muaj xws li kev ua kom zoo ntawm cov pob txha tawg, txo kom txaus ntawm cov pob txha, qhov tsim nyog ntawm cov ntsia hlau thiab qhov ntev, thiab kev nruj ntawm cov ntsia hlau. Cov teeb meem ntawm kev tshem tawm cov ntsia hlau muaj xws li ntsia hlau loosening, ntsia hlau tawg, ntsia hlau tsiv teb tsaws, tsis muaj kev sib koom ua ke, malunion, kab mob, thiab paj hlwb lossis hlab ntsha raug mob.
Cov txiaj ntsig ntawm Cancellous Screw Fixation
Cov txiaj ntsig ntawm kev tshem tawm cov ntsia hlau yog nyob ntawm qhov qhia tshwj xeeb thiab tus neeg mob yam xwm txheej, xws li hnub nyoog, comorbidities, thiab kev haus luam yeeb. Nyob rau hauv dav dav, cancellous ntsia hlau fixation muab kev ruaj ntseg zoo heev thiab compression ntawm cov pob txha tawg, uas ua rau cov pob txha kho tau sai thiab rov qab ua haujlwm zoo. Qhov kev vam meej ntawm kev tshem tawm cov ntsia hlau kho qhov sib txawv ntawm 80% mus rau 95%, nyob ntawm qhov taw qhia thiab cov qauv tawg. Cov teeb meem ntawm kev tshem tawm cov ntsia hlau tuaj yeem ua rau cov txiaj ntsig tsis zoo, xws li kev kho qeeb, tsis muaj kev sib koom ua ke, thiab mob ntev.

Cancellous screws yog cov cuab yeej siv ntau yam thiab siv tau zoo hauv kev phais orthopedic rau kev kho cov pob txha pob txha, grafts, thiab fusion. Kev siv cov ntsia hlau tshem tawm kom raug yuav tsum muaj kev nkag siab zoo ntawm lub cev, qhov taw qhia, cov txheej txheem, thiab cov txiaj ntsig ntawm cov txheej txheem. Kev xaiv ntawm qhov tsim nyog ntsia hlau loj, qhov ntev, thiab cov txheej txheem ntxig yuav tsum tau ua kom haum rau cov qauv pob txha tshwj xeeb thiab cov neeg mob. Kev siv cov ntsia hlau tshem tawm tuaj yeem ua rau muaj txiaj ntsig zoo thiab kho tau sai, tab sis ceev faj saib xyuas thiab tswj cov teeb meem yog qhov tseem ceeb rau kev pom zoo.
