PEEK Ibikoresho byo kuvura umugongo Fusion Cage
PEEK urutirigongo, nanone rwitwa interbody fusion cage, rukoreshwa muburyo bwo guhuza uruti rwumugongo kugirango rusimbuze disiki yumugongo yangiritse kandi rutange ibidukikije byiza kugirango vertebrae ebyiri zishyire hamwe.PEEK interbody fusion cage ishyizwe hagati yintegamubiri zombi zigomba guhuzwa.

Inama z'ubuvuzi
TILF ni iki?
TLIF ni uburyo bumwe bwo guhuza abantu kugirango bagarure uburebure busanzwe bwimyanya ndangagitsina hamwe na lombar spine physiologique lordose.Tekinike ya TLIF yatangajwe bwa mbere na Harms mu 1982. Irangwa nuburyo bwinyuma, bwinjira mu muyoboro wumugongo kuva kuruhande rumwe.Kugirango ugere ku mubiri w’ibihimba byombi, nta mpamvu yo kwivanga mu muyoboro wo hagati, bigabanya kubaho kw'amazi yo mu bwonko ava mu bwonko, ntibikeneye kurambura imizi ya nervice na sac ya dural cyane, kandi bigabanya amahirwe yo kwangirika kw'imitsi.Ihuriro rya lamina hamwe nibice byabitswe birabitswe, agace kamagufwa kongerewe, 360 ° fusion birashoboka, ligaments zidasanzwe kandi zuzuzanya, zishobora kongera kubaka imiterere yinyuma yinyuma yinyuma yumugongo.
PILF ni iki?
PLIF (posterior lumbar interbody fusion) nubuhanga bwo kubaga bwo guhuza vertebrae yo mu bwoko bwa lombar ukuraho disiki ya intervertebral hanyuma ukayisimbuza akazu (titanium).Urusenda noneho ruhagarikwa na fixer y'imbere (transpedicular instrumented dorsal WK fusion).PLIF nigikorwa gikaze kumugongo
Bitandukanye na ALIF (imbere ya lumbar intervertebral fusion), iki gikorwa gikorerwa inyuma, ni ukuvuga inyuma.Uburyo bwo kubaga PLIF ni TLIF ("transforaminal lumbar interbody fusion").
Bikora gute?
Uruti rw'umugongo PEEK akazu ka radiolucent cyane, bio-inert, kandi irahuza na MRI.Akazu kazakora nk'umwanya ufite hagati ya vertebrae yibasiwe, hanyuma itume igufwa rikura kandi amaherezo riba igice cyumugongo.
Ibyerekana
Ibimenyetso bishobora kuba bikubiyemo: discogenic / facetogenic ububabare bwo mu mugongo, claudication ya neurogeneque, radiculopathie bitewe na stenosis foraminal stenosis, ubumuga bwumugongo bwangirika burimo ibimenyetso bya spondylolisthesis na scoliyose degenerative.
Inyungu
Uruzitiro rukomeye rushobora gukuraho umuvuduko, kongera umwanya wimizi yumutima, guhagarika urutirigongo, kugarura uruti rwumugongo, no kugabanya ububabare.
Ibikoresho byo mu kato
Polyetheretherketone (PEEK) ni biopolymer idashobora gukoreshwa yakoreshejwe mu nganda zitandukanye zirimo ibikoresho byubuvuzi.Akazu ka PEEK ni biocompatable, radiolucent, kandi ifite modulus ya elastique isa nigufwa.
