Ikheji ye-PEEK yomlomo wesibeletho iyi-radiolucent interbody fusion implant eyenzelwe ukusetshenziswa ku-anterior cervical discectomy kanye nezinqubo ze-fusion (ACDF). Ifakwe phakathi kwemizimba ye-vertebral yomlomo wesibeletho ngemva kokususwa kwe-disc ukubuyisela ukuphakama kwe-disc, ukugcina ukulungiswa komlomo wesibeletho, nokuhlinzeka indawo ezinzile yokuhlanganiswa kwamathambo.
Kwenziwe kusukela ku-polyetheretherketone yezinga lezokwelapha (PEEK), lokhu kufakelwa kusetshenziswa kabanzi ekuhlinzeni umgogodla womlomo wesibeletho yesimanje ngenxa yokuhambisana kwayo kwe-biomechanical nethambo kanye nokusebenza kwayo okuhle kakhulu kwesithombe ngesikhathi sokulandelela ngemuva kokuhlinzwa.
Ukuqonda Umsebenzi we-Cervical PEEK Cage ku-Cervical Spine Surgery
Ikheji ye-PEEK yomlomo wesibeletho isebenza njenge-interbody spacer esekela ikholomu yangaphambili yomgogodla wesibeletho ngemva kokuwohloka. Ngokugcina isikhala se-intervertebral, i-cage isiza ukugcina ukuphakama kwe-neural foraminal futhi inciphisa ingozi yokucindezelwa kwe-postoperative nerve.
Ezinqubweni ze-ACDF, ikheji ibekwe ngemuva kokususwa kwe-disc ewohlokile noma ye-herniated. Impahla ye-graft yethambo ipakishwa ekhejini ukuze ikhuthaze ukuhlangana phakathi kwama-vertebrae aseduze, kancane kancane yakhe ibhuloho eliqinile lamathambo ngokuhamba kwesikhathi.
Uma kuqhathaniswa nokufakelwa kwensimbi, amakheji e-PEEK avumela odokotela abahlinzayo ukuthi bahlole inqubekelaphambili ye-fusion ngokucacile, okudlala indima ebalulekile ekuthathweni kwezinqumo kwangemva kokuhlinzwa kanye nokuhlola umphumela wesikhathi eside.
Izinkomba Zomtholampilo kanye Nezicelo Ezijwayelekile
Amakheji e-PEEK yomlomo wesibeletho avame ukuboniswa ezigulini ezine-disc degenerative degenerative yomlomo wesibeletho, i-cervical disc herniation, kanye ne-spondylosis yomlomo wesibeletho ezidinga ukuchithwa kwangaphambili nokuzinza. Lezi zimo zivame ukubangela ubuhlungu bentamo, i-radiculopathy, noma i-myelopathy ngenxa yokucindezelwa kwezinzwa noma umgogodla.
Ezimweni ezikhethiwe, ukufakelwa kungase kusetshenziswe futhi ekuhlukumezeni komlomo wesibeletho okubandakanya ukuwa kwe-disc noma ukungazinzi kwesigaba, ikakhulukazi uma kuhlanganiswe nesistimu yepuleti yomlomo wesibeletho yangaphambili ukuze kuthuthukiswe amandla okulungisa.
Ukufakelwa kuvame ukusetshenziswa emazingeni omlomo wesibeletho amaphakathi kuya kwaphansi, ngokuvamile ukusuka ku-C3 kuye ku-C7, amele amasegimenti alashwa kakhulu ekuhlinzweni kwe-ACDF.
Izici Ezibalulekile kanye Nezinzuzo ze-PEEK ku-Cervical Fusion
I-PEEK iyi-polymer esebenza kahle kakhulu ene-elastic modulus eseduze naleyo ye-cortical bone kune-titanium. Lesi sakhiwo sivumela ukwabelana okuningi komthwalo wemvelo kuyo yonke ingxenye yokuhlanganisa futhi kusiza ukunciphisa ukuvikela ingcindezi, okuhlotshaniswa nokulibaziseka noma ukuhlanganisa okungaphelele.
Enye inzuzo enkulu ye-PEEK i-radiolucency yayo. Ngokungafani namakheji ensimbi, i-PEEK ayikhiqizi ama-artifact ezithombe, ivumela ukubonakala okucacile kokukhula kwamathambo nokuqhubeka kokuhlanganiswa kuma-X-ray, CT, kanye nezikena ze-MRI.
Ukuze kusekelwe ukuma okunembile kokufakwayo, omaka be-radiopaque bashumekwa ngaphakathi kwekheji, okuvumela odokotela abahlinzayo ukuthi baqinisekise ukubekwa phakathi nokuhlinzwa nokuthwebula izithombe ngemva kokuhlinzwa ngaphandle kokufaka engcupheni ukucaca kwesithombe.
Idizayini Yesakhiwo kanye neJiyomethri Egxile ku-Fusion
I-Cervical PEEK Cage II yakhelwe ngephrofayili ekhonjisiwe ye-anatomically ehambisana nama-endplates omlomo wesibeletho. Lo mklamo usiza ukusabalalisa umthwalo ngokulinganayo kuyo yonke imizimba yama-vertebral futhi unciphise ubungozi bokufakwa kwe-subsidence.
Iwindi elikhulu eliphakathi nendawo livumela ukupakishwa okwanele kwe-autograft, i-allograft, noma izinto ezithatha indawo yamathambo. Lesi sakhiwo esivulekile sikhuthaza i-vascularization kanye ne-ingrowth yamathambo, okuyizici ezibalulekile zokufeza ukuhlanganiswa okuthembekile kwe-interbody.
Amazinyo aphikisana nokufuduka kanye nombhalo ongaphezulu kufakwa ekhejini ukuze kuthuthukiswe ukuzinza kwasekuqaleni futhi kuncishiswe ubungozi bokufuduka phakathi nokunyakaza kwangaphambi kokuhlinzwa.
Igalelo Ekuqondaneni Komlomo Wesibeletho kanye Nokuqina Kwe-Biomechanical
Ngokubuyisela ukuphakama kwe-disc, i-cage inomthelela ekubuyiseleni i-lordosis yomlomo wesibeletho kanye nokuhlelwa kwesigaba. Ukuqondanisa okufanele kubalulekile ekwehliseni ukucindezeleka okungavamile kwe-biomechanical ezingxenyeni eziseduze kanye nokwenza ngcono imiphumela yesikhathi eside yomtholampilo.
Ikheji lisebenza ngokubambisana nezakhiwo ezizungezile ze-anatomical futhi, uma kudingekile, namapuleti omlomo wesibeletho angaphambili ukuze anikeze ukusekelwa kwemishini ngokushesha kuyilapho ukuhlanganisa kukhula kancane kancane ngokuhamba kwesikhathi.
Ukuhambisana ne-Anterior Cervical Fixation Systems
I-Cervical PEEK Cage II iklanyelwe ukuhlanganisa ngaphandle komthungo nokugeleza komsebenzi okujwayelekile kwe-ACDF. Ingasetshenziswa njengedivayisi ye-interbody ezimele ezimweni ezikhethiwe noma ihlanganiswe ne-anterior cervical plate kanye ne-screw systems ukuze kuthuthukiswe amandla okulungisa.
Idizayini yayo ihambisana nezinsimbi ezisetshenziswa kakhulu zomlomo wesibeletho, okuvumela odokotela abahlinzayo ukuthi basebenzise isimila ngaphandle kwezinguquko eziphawulekayo endleleni yabo yokuhlinza.
Izinketho Zosayizi, Ukucaciswa, kanye Namakhono Okwenza Ngokwezifiso
Uhlu olubanzi lwezinyathelo nobude buyatholakala ukuze kuhlaliswe ama-anatomi esiguli ahlukene kanye nezidingo zesikhala sediski. Lokhu kuvumelana nezimo kuvumela odokotela abahlinzayo ukuthi bafinyelele ukulingana okuphelele nokuqondanisa phakathi nokuhlinzwa.
Kubasabalalisi nozakwethu be-OEM, izinketho zokwenza ngendlela oyifisayo zingabandakanya ukulebula okuyimfihlo, ukulungiselelwa kokupakisha, nokuhlelwa kosayizi okuhlukahlukene ukuze kuhlangatshezwane nezidingo ezithile zemakethe noma zokuthengwa kwesibhedlela.
Ukuvala inzalo, ukupakishwa, kanye nokuqinisekisa ikhwalithi
I-implant ingahlinzekwa ngamaphakeji ayinyumba noma angenayo inyumba kuye ngemithetho yesifunda kanye nezinketho zesibhedlela. Zonke izinqubo zokukhiqiza zenziwa ngaphansi kwezinhlelo zokuphatha ikhwalithi eziqinisekisiwe ze-ISO ukuze kuqinisekiswe ukungaguquguquki, ukulandeleka, nokuphepha komkhiqizo.
Amadokhumenti aphelele, okuhlanganisa amafayela obuchwepheshe namarekhodi ekhwalithi, ayatholakala ukuze asekele ukuhanjiswa okulawulwayo nokubhaliswa kwezimakethe ezifundeni ezihlukahlukene.
Ukucatshangelwa Kwabasabalalisi, Abangenisi, kanye Nabathengi Besibhedlela
Ngokombono wokuthenga, amandla okunikeza okungaguquki kanye nokunemba kobukhulu be-batch-to-batch yizici ezibalulekile lapho kukhethwa umhlinzeki wokufakelwa komlomo wesibeletho. Izinqubo zokukhiqiza ezizinzile zisiza ukuqinisekisa ukusebenza komtholampilo okubikezelwayo kanye nokutholakala kwesikhathi eside.
Ngaphezu kwekhwalithi yomkhiqizo, ukwesekwa kwamadokhumenti kanye nokuxhumana okuphendulayo kubalulekile kubasabalalisi abasebenza ezimakethe ezilawulwayo zemishini yezokwelapha.
Imibuzo Evame Ukubuzwa Ngamakheji e-Cervical PEEK
Ingabe ikheji ye-PEEK yomlomo wesibeletho ifanele zonke izinqubo ze-ACDF?
Amakheji e-Cervical PEEK asetshenziswa kakhulu ezinqubweni ze-ACDF, kodwa ukukhetha kokugcina kuncike ku-anatomy yesiguli, i-pathology, kanye nokuthandwa kodokotela abahlinzayo.
Yiziphi izinzuzo zamakheji e-PEEK uma kuqhathaniswa namakheji e-titanium?
Amakheji e-PEEK anikeza i-radiolucency kanye ne-elastic modulus eduze nethambo, okungase kunciphise ukuvikela ukucindezeleka futhi kuvumele ukucabanga okucacile kwangemva kokuhlinzwa.
Ingabe leli kheji lingasetshenziswa ngaphandle kwepuleti lomlomo wesibeletho elingaphambili?
Ezimweni ezikhethiwe, ukusetshenziswa okuzimele kungase kulungele, kodwa ukulungiswa okwengeziwe ngepuleti yomlomo wesibeletho kuvame ukunconywa ukuthuthukisa ukuzinza.
Yiziphi izinto zokuxhunyelelwa amathambo ezingasetshenziswa nalokhu kufakelwa?
I-Autograft, i-allograft, kanye nezinye esikhundleni samathambo zingasetshenziswa kuye ngezidingo zomtholampilo kanye nokuthandwa kodokotela abahlinzayo.
Isikhundla sokufakelwa siqinisekiswa kanjani ngemva kokuhlinzwa?
Omaka be-Radiopaque abashumekwe ekhejini bavumela ukuhlolwa okunembile kwendawo yokufakelwa kusetshenziswa izindlela ezijwayelekile zokuthwebula.
Ingabe lo mkhiqizo uyatholakala ku-OEM noma ukunikezwa ilebula yangasese?
Yebo, i-OEM nezinketho zelebula yangasese ziyatholakala kubasabalalisi abaqeqeshiwe, ngokuya ngezidingo zokulawula zesifunda.
