Lub patella yog nyob rau hauv pem hauv ntej ntawm lub hauv caug sib koom tes, nws txoj hauj lwm yog ib qho superficial, thiab nws yog ib qho yooj yim rau kov nrog ob txhais tes.Lub patella yog ib feem ntawm lub hauv caug extensor mechanism, uas yog, patella yog ib qho tseem ceeb ntawm cov pob txha uas txuas cov leeg ntawm tus ncej puab thiab cov leeg nyob rau hauv pem hauv ntej ntawm tus ncej puab.
Thaum cov nqaij ntshiv ntawm tibia yog tag nrho ncab, patella tuaj yeem pab ua kom lub hauv caug sib koom ua ke, ua kom tibia thiab femur nyob rau hauv kab kab rov tav, yog li ua lub luag haujlwm ntawm kev tsa ceg.
Yog tsis muaj patella lub hauv caug pob qij txha yuav muaj sij hawm nyuaj dua khoov thiab ncaj.lub patella zoo li fulcrum thiab cov pob txha ceg zoo li levers.
Lub patella tuaj yeem tiv thaiv lub hauv caug sib koom ua ke, pob txha ntawm patella feem ntau tshwm sim los ntawm kev sib tsoo ncaj qha rau hauv caug, xws li lub caij nplooj zeeg lossis lub tsheb sib tsoo.
Kneecap fractures yuav yooj yim los yog complex.
Ib pob txha ntawm patella yog pob txha uas tshwm sim los ntawm kev raug mob.Feem ntau ntawm cov pob txha patella yog kaw cov pob txha, uas cov patella tsis tawg ntawm daim tawv nqaij.Ib qho loj patella tawg tuaj yeem ua rau nws nyuaj lossis txawm tias tsis yooj yim rau koj lub hauv caug los yog taug kev. txawm tias nws muaj teeb meem xws li patella-femoral mob caj dab, ncua sij hawm. Kev sib koom ua ke ntawm patella, thiab rov tawg ntawm patella.
Nyob rau hauv tsab xov xwm no, cov cables peb tau hais, raws li cov txheej txheem ib txwm siv, cov khoom siv feem ntau yog cov hlau tuab thiab hlau hlau.Txawm hais tias cov khoom siv no muab kev sib npaug sib npaug ntawm kev ntxhov siab thiab ntau txoj kev sib koom ua ke, nws tsis tuaj yeem txwv qhov kev sib cais thiab kev txav ntawm lub hauv ntej thaum lub sij hawm flexion thiab txuas ntxiv, yog li qhov kev ruaj ntseg yog qhov nruab nrab, thiab kev kho sab nraud nrog cov khoom siv tseem ceeb.
Lub hauv paus ntsiab lus ntawm kev siv yog yooj yim: cov pob txha tawg sib sau ua ke mus rau qhov chaw ntawm patella, tiv thaiv qhov nro nyob ib ncig ntawm patella, thiab ua tiav lub hom phiaj ntawm kev txo qis thiab kho.Nws yog tsim rau cov neeg mob uas muaj comminuted fractures ntawm patella los yog transverse fractures ntawm nruab nrab ntu ntawm lub patella nrog kev sib cais thiab tsiv, thiab articular nto yog tseem du thiab zoo tom qab tawg txo.
Cov kab hluav taws xob (titanium cable, cable) yog cov qauv zoo li cov kab hluav taws xob uas tsim los ntawm ntau cov hlua ntawm nyias titanium hlau, uas feem ntau yog siv rau sab hauv kho pob txha raug mob.
Cov khoom siv no muaj cov khoom siv zoo heev, zoo bio-compatibility, thiab corrosion thiab hnav tsis kam.Nws raug suav hais tias yog ib qho ntawm cov khoom siv hlau zoo tshaj plaws hauv kev lag luam bio-tshuaj.
Titanium cable qhia 3 ~ 6 npaug ntawm lub zog tensile ntawm steel hlau nrog tib txoj kab uas hla, thiab nws cov kev ua tau zoo los tiv thaiv kev qaug zog yog qhov tseem ceeb tshaj li cov hlau hlau, ncav cuag 9 ~ 48 zaug;
Tsis tas li ntawd, titanium cable muaj cov ntaub so ntswg zoo sib xws, tsis muaj tshuaj lom, tsis muaj kev cuam tshuam ntawm lub cev txawv teb chaws, tuaj yeem tso rau hauv lub cev yam tsis tau tshem tawm, thiab tsis cuam tshuam rau tus neeg mob qhov kev kuaj MRI.
Cov neeg uas tawg lawv patella tej zaum yuav nyuaj taug kev los yog ncab lawv txhais ceg.Cov neeg feem coob tuaj yeem rov qab mus rau qhov kev ua ub no nyob rau hauv3–6 lub hlis
