Fusion Cage
I-PEEK ii-spinal cages, ezikwabizwa ngokuba yi-interbody fusion cages, zisetyenziselwa iinkqubo ze-spinal fusion ukuze zithathe indawo ye-spinal disc eyonakeleyo kwaye inike indawo efanelekileyo yokuba ii-vertebrae ezimbini zidibanise kunye.I-PEEK interbody fusion cages ibekwe phakathi kwee-vertebrae ezimbini eziza kuhlanganiswa.

Yintoni i-TILF?
I-TLIF yindlela ehlangeneyo yokudibanisa i-interbody ukubuyisela ubude bendawo ye-intervertebral kunye ne-lumbar spine physiological lordosis.Ubuchwephesha be-TLIF buqale ukuxelwa yi-Harms kwi-1982. Ibonakaliswa yindlela yangasemva, engena kumgudu womgogodla ukusuka kwelinye icala.Ukufezekisa ukudibanisa kwe-vertebral body fusion, akukho mfuneko yokuphazamisa umjelo ophakathi, onciphisa ukuvela kwe-cerebrospinal fluid ukuvuza, akudingi ukolula ingcambu ye-nerve kunye ne-dural sac kakhulu, kwaye inciphisa amathuba okulimala kwe-nerve.I-lamina ye-contralateral kunye ne-facet joints igcinwe, indawo ye-bone graft iyanda, i-360 ° fusion inokwenzeka, i-supraspinous kunye ne-interspinous ligaments igcinwe, ekwazi ukuvuselela i-posterior tension band structure ye-lumbar spine.
Yintoni iPILF?
I-PLIF (i-posterior lumbar interbody fusion) yindlela yokwenza utyando lokudibanisa i-lumbar vertebrae ngokususa i-intervertebral disc kunye nokubeka indawo ye- (titanium) yekheji.Emva koko i-vertebrae iqiniswa yi-fixator yangaphakathi (i-transpedicular instrumented dorsal WK fusion).I-PLIF ngumsebenzi wokuqina kumqolo
Ngokuchasene ne-ALIF (i-anterior lumbar intervertebral fusion), lo msebenzi wenziwa ukusuka ngasemva, oko kukuthi ukusuka ngasemva.Umahluko wotyando we-PLIF yiTLIF ("transforaminal lumbar interbody fusion").
Ingaba isebenza kanjani?
I-PEEK cages yomlomo wesibeleko i-radiolucent kakhulu, i-bio-inert, kwaye iyahambelana ne-MRI.I-cage iya kusebenza njengomphathi wendawo phakathi kwe-vertebrae echaphazelekayo, kwaye emva koko ivumela ithambo ukuba likhule kwaye ekugqibeleni libe yinxalenye yomqolo.
Iimpawu
Izibonakaliso zingabandakanya: i-discogenic / facetogenic low back pain, i-neurogenic claudication, i-radiculopathy ngenxa ye-foraminal stenosis, i-lumbar degenerative spinal deformity kuquka i-spondylolisthesis ye-symptomatic kunye ne-degenerative scoliosis.
Ngeneza
I-fusion ye-cage eqinile inokuphelisa ukunyakaza, ukwandisa indawo yeengcambu ze-nerve, ukuzinzisa umqolo, ukubuyisela ukulungelelaniswa komqolo, kunye nokunciphisa intlungu.
Izinto eziphathekayo zekheji yokudibanisa
I-Polyetheretherketone (PEEK) yi-biopolymer engabonakaliyo esetyenziswe kwiindidi ezahlukeneyo zamashishini kuquka nezixhobo zonyango.I-PEEK cages i-biocompatible, i-radiolucent, kwaye ine-modulus ye-elasticity efana nethambo.
