Fusion Cage
PEEK spinal cages, zomwe zimatchedwanso interbody fusion cages, zimagwiritsidwa ntchito muzitsulo za msana kuti zilowe m'malo mwa diski yowonongeka ya msana ndikupereka malo abwino kuti ma vertebrae awiri agwirizane.PEEK interbody fusion cages ali pakati pa vertebrae ziwiri zomwe ziyenera kusakanikirana.

TILF ndi chiyani?
TLIF ndi njira imodzi yokha yolumikizirana kuti abwezeretse kutalika kwa danga la intervertebral ndi lumbar spine physiological lordosis.Njira ya TLIF idanenedwa koyamba ndi Zowopsa mu 1982. Imadziwika ndi njira yopita kumbuyo, yomwe imalowa mumtsinje wa msana kuchokera kumbali imodzi.Kuti tikwaniritse amgwirizano vertebral thupi maphatikizidwe, palibe chifukwa kusokoneza chapakati ngalande, amene amachepetsa zochitika za cerebrospinal madzimadzi kutayikira, safuna kutambasula mitsempha muzu ndi wapawiri sac kwambiri, ndi kuchepetsa Mwina kuwonongeka kwa mitsempha.Ma contralateral lamina ndi ziwalo zamagulu zimasungidwa, gawo la fupa la mafupa likuwonjezeka, kusakanikirana kwa 360 ° n'kotheka, mitsempha ya supraspinous ndi interspinous imasungidwa, yomwe imatha kukonzanso kamangidwe kameneka kamene kali m'chiuno.
PILF ndi chiyani?
PLIF (posterior lumbar interbody fusion) ndi njira yopangira opaleshoni yosakaniza vertebrae ya lumbar pochotsa intervertebral disc ndi kuika (titanium) khola.Mitsemphayo imakhazikika ndi chowongolera chamkati (transpedicular instrumented dorsal WK fusion).PLIF ndi ntchito yowumitsa msana
Mosiyana ndi ALIF (anterior lumbar intervertebral fusion), opaleshoniyi imachitidwa kuchokera kumbuyo, mwachitsanzo kuchokera kumbuyo.Mtundu wina wa opaleshoni wa PLIF ndi TLIF ("transforaminal lumbar interbody fusion").
Zimagwira ntchito bwanji?
Mitsempha ya khomo lachiberekero PEEK makola ndi radiolucent kwambiri, bio-inert, ndipo n'zogwirizana ndi MRI.Khola lidzakhala ngati chosungira danga pakati pa vertebrae yomwe yakhudzidwa, ndiyeno imalola kuti fupa likule ndipo pamapeto pake limakhala gawo la msana.
Zizindikiro
Zizindikiro zingaphatikizepo: discogenic / facetogenic low back ululu, neurogenic claudication, radiculopathy chifukwa cha foraminal stenosis, lumbar degenerative spinal deformity kuphatikizapo symptomatic spondylolisthesis ndi degenerative scoliosis.
Pindulani
Kuphatikizika kolimba kwa khola kumatha kuthetsa kusuntha, kuonjezera malo a mizu ya mitsempha, kukhazikika kwa msana, kubwezeretsa msana, ndi kuthetsa ululu.
Zinthu za fusion khola
Polyetheretherketone (PEEK) ndi biopolymer yosatengeka yomwe yakhala ikugwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza zida zamankhwala.Makola a PEEK ndi biocompatible, radiolucent, ndipo ali ndi modulus of elasticity yofanana ndi fupa.
