I-Fusion Cage
Amakheji omgogodla we-PEEK, abuye abizwe ngokuthi amakheji e-interbody fusion, asetshenziswa ezinkambisweni zokuhlanganisa umgogodla ukuze athathe indawo ye-spinal disc eyonakele futhi anikeze indawo ekahle yokuthi ama-vertebrae amabili ahlangane ndawonye.Amakheji e-PEEK interbody fusion abekwe phakathi kwama-vertebrae amabili okufanele ahlanganiswe.

Yini i-TILF?
I-TLIF iyindlela ehlangene yokuhlanganiswa kwe-interbody ukubuyisela ukuphakama kwesikhala esivamile se-intervertebral kanye ne-lumbar spine physiological lordosis.Inqubo ye-TLIF yabikwa okokuqala yi-Harms ngo-1982. Ibonakala ngendlela engemuva, engena emgodini womgogodla ukusuka ohlangothini olulodwa.Ukuze kuzuzwe ukuhlanganiswa komzimba we-vertebral bilateral, asikho isidingo sokuphazamisa umsele ophakathi, okunciphisa ukuvela kokuvuza kwe-cerebrospinal fluid, akudingi ukwelula impande ye-nerve ne-dural sac kakhulu, futhi kunciphisa amathuba okulimala kwezinzwa.I-contralateral lamina kanye nama-facet joints ayagcinwa, indawo ye-graft ye-bone iyanda, i-360 ° fusion ingenzeka, i-supraspinous ne-interspinous ligaments iyagcinwa, engakha kabusha isakhiwo se-posterior tension band ye-lumbar spine.
Yini i-PILF?
I-PLIF (i-posterior lumbar interbody fusion) iyindlela yokuhlinza yokuhlanganisa i-lumbar vertebrae ngokukhipha i-intervertebral disc bese ifaka ikheji (ye-titanium).Ama-vertebrae abe eseqiniswa yi-fixator yangaphakathi (i-transpedicular instrumented dorsal WK fusion).I-PLIF wukuhlinzwa okuqinisa umgogodla
Ngokuphambene ne-ALIF (i-anterior lumbar intervertebral fusion), lo msebenzi wenziwa kusukela ngemuva, okungukuthi ngemuva.Okuhlukile kokuhlinzwa kwe-PLIF yi-TLIF ("transforaminal lumbar interbody fusion").
Isebenza kanjani?
Amakheji e-PEEK omgogodla womlomo wesibeletho akhanya kakhulu, ane-bio-inert, futhi ayahambisana ne-MRI.Ikheji lizosebenza njengomphathi wesikhala phakathi kwama-vertebrae athintekile, bese livumela ithambo ukuba likhule futhi ekugcineni libe yingxenye yomgogodla.
Izinkomba
Izinkomba zingabandakanya: ubuhlungu obuphansi be-discogenic/facetogenic, i-neurogenic claudication, i-radiculopathy ngenxa ye-foraminal stenosis, i-lumbar degenerative deformity yomgogodla ohlanganisa i-spondylolisthesis ye-symptomatic kanye ne-degenerative scoliosis.
Zuza
Ukuhlanganiswa kwekheji okuqinile kungaqeda ukunyakaza, kwandise isikhala sezimpande zezinzwa, kusimamise umgogodla, kubuyisele ukuhleleka komgogodla, futhi kudambise ubuhlungu.
Impahla yekheji ye-fusion
I-Polyetheretherketone (PEEK) i-biopolymer engamuncwa esetshenziswe ezimbonini ezahlukahlukene ezihlanganisa nemishini yezokwelapha.Amakheji e-PEEK ahambisana ne-biocompatible, ane-radiolucent, futhi ane-modulus of elasticity efana nethambo.
