Akazu
PEEK uruti rwumugongo, nanone rwitwa interbody fusion cage, rukoreshwa muburyo bwo guhuza uruti rwumugongo kugirango rusimbuze disiki 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 nuburyo bumwe bwo guhuza abantu kugirango bagarure uburebure busanzwe bwimyanya ndangagitsina hamwe na spor physiologique lordose.Tekinike ya TLIF yatangajwe bwa mbere na Harms mu 1982. Irangwa nuburyo bwinyuma, bwinjira mumurongo wumugongo kuva kuruhande rumwe.Kugirango ugere ku mubiri w’ibihimba byombi, nta mpamvu yo kwivanga mu muyoboro wo hagati, bigabanya ikibazo cyo kuva mu bwonko bwa cerebrospinal fluid, ntibikenera kurambura imizi yimitsi nigitereko cyigihe kinini, kandi bikagabanya amahirwe yo kwangirika kwimitsi.Ihuriro rya lamina hamwe nu gice cyo kuruhande birabitswe, agace kamagufwa kiyongereye, 360 ° fusion birashoboka, ligaments supraspinous na interspinous ligaments zirabitswe, zishobora kongera kubaka imiterere yinyuma yinyuma yumugongo.
PILF ni iki?
PLIF (posterior lumbar interbody fusion) nubuhanga bwo kubaga bwo guhuza vertebrae yo gukuramo disiketi hagati 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 cage ni radiolucent cyane, bio-inert, kandi irahuza na MRI.Akazu kazakora nk'umwanya uri hagati ya vertebrae yibasiwe, hanyuma itume igufwa rikura kandi amaherezo riba igice cyumugongo.
Ibyerekana
Ibimenyetso bishobora kubamo: discogenic / facetogenic ububabare bwo mu mugongo, claudication ya neurogeneque, radiculopathie bitewe na foraminal stenosis, lumbar degenerative spinal deformation harimo ibimenyetso bya spondylolisthesis na degenerative scoliose.
Inyungu
Uruvangitirane rukomeye rushobora gukuraho umuvuduko, kongera umwanya kumizi 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 biocompatible, radiolucent, kandi ifite modulus ya elastique isa nigufwa.
