Tus ceg qis ntawm tus neeg yog ib feem ntawm cov ceg qis, uas nyob nruab nrab ntawm tus ncej puab thiab ko taw. Xwm tau tsim cov ntu no raws li txoj hauv kev uas nws tuaj yeem tiv taus cov khoom loj uas tshwm sim los ntawm lub cev ncaj ncees ntawm homo sapiens. Ob lub pob txha muaj zog heev: sab nraud - fibula, sab hauv - tibia - tsim sab ceg. Daim duab qhia txog qhov txheeb ze thiab cov qauv ntawm cov pob txha.
Cov leeg nqaij ntawm lub cev no tau muab faib ua 3 pawg: cov extensors ntawm ko taw thiab ntiv tes (cov pab pawg sab nrauv), tom qab ntawd cov leeg uas flex, abduct thiab nkag mus rau ko taw (sab nraud, lossis sab nraud, pab pawg), thiab, thaum kawg, cov flexors (tom qab pawg).
Qee zaum muaj xwm txheej tshwm sim thaum, vim muaj ntau yam txheej txheem pathological thiab kev raug mob, tib txoj kev rau kev cawm seej yog kev txiav ntawm tus neeg sab ceg. Tus neeg mob poob nws txhais ceg, thiab nrog nws lub peev xwm txav mus los ntawm nws tus kheej. Tshuaj muaj ib txoj kev tawm ntawm qhov teeb meem no - prosthetics.
Cov txheej txheem no yog hloov cov ntu uas ploj lawm lossis tag nrho cov ceg tawv nrog kev pab los ntawm cov cuab yeej tshwj xeeb txhawm rau txhawm rau kho cov duab anatomical thiab kev ua haujlwm ntawm thaj chaw no ntawm lub cev kom ntau li ntau tau. Cov khoom siv nyob rau hauv cov ntaub ntawv no suav nrog prostheses, corsets, orthoses (orthopedic devices), thiabnkawm khau tshwj xeeb orthopedic.
Cov khoom siv no rov qab ib nrab lossis tag nrho cov kev txhawb nqa thiab lub cev muaj zog ntawm ntu puas, pab tsim cov xwm txheej zoo tshaj plaws rau kev kho kom rov zoo, thiab txo qhov kev pheej hmoo ntawm cov teeb meem.
Cov ceg qis qis yog ib qho ntawm cov khoom siv ntau tshaj plaws. Ib qho me me ntawm cov leeg nqaij, pob txha protrusions ntawm lub ntsej muag sab hauv ntawm tibia, nrog rau kev noj zaub mov tsis txaus nyob rau hauv cheeb tsam no ua rau nws nyuaj heev los tsim kom muaj kev zoo nkauj thiab zoo.
Los ntawm qhov pom ntawm lub cev thiab lub cev nqaij daim tawv, lub peev xwm ntawm cov pob txha tuaj yeem tiv taus lub nra ntawm tus ceg qis ntawm tus neeg sib txawv ntawm ntau theem ntawm kev txiav tawm. Lub hauv paus ntsiab lus tseem ceeb hais tias: nyob rau hauv kev sib raug zoo rau cov ntaub so ntswg noj qab haus huv, ntau lub dag prosthesis yog loaded, ntau physiological tus tsim yuav. Tias yog vim li cas cov kws phais neeg xaiv cov qib siab ntawm cov ceg qis qis: ntau cov leeg nqaij yuav pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txiav cov ceg, cov leeg ntau yuav pab txhawb nqa cov leeg pob txha. ntawm qhov khoom cuav.
Prosthetic ceg ntawm tus neeg, ua raws li cov hauv qab no. Lub stump yuav tsum tau ua raws li qhov tau txais cov tshuaj ntsiav. Tom qab ntawd lub load yuav tsum muab sib npaug zos rau tag nrho cov anatomical formations nyob rau saum npoo ntawm stump. Tsis tas li ntawd, qhov kev kwv yees ntawm cov axes ntawm lub hauv caug thiab pob taws pob qij txha yuav tsum phim raws nraim.
Tsis muaj leej twg tuaj yeem nyob tau yooj yim yam tsis muaj lub sijhawmtxav tau ywj siab. Tib neeg lub shin yog ib feem tseem ceeb ntawm lub cev musculoskeletal. Kev poob ntawm ntu no ua rau tus neeg tsis taus, deprives lub peev xwm txav mus los. Qhov muaj peev xwm ntawm cov tshuaj nyob rau hauv dav dav thiab prosthetics tshwj xeeb nyob rau hauv cov ntaub ntawv no yuav tsis tau overestimated.
