Mukupindura kumatambudziko ari pamusoro, nharaunda yevadzidzi inogara ichishanda pakuvandudza tekinoroji, mabhindauko epfungwa, uye prosthesis optimization. Iko-self-stabilising cervical spine fusion device (zero-trace), iyo inonyatsogadziriswa munzvimbo ye intervertebral uye inobudirira inoderedza dambudziko re postoperative dysphagia uye kuderera kwechikamu chepedyo, yakagamuchirwa zvikuru.
Matambudziko epashure ane chekuita neprostheses anokurukurwa pazasi --
1.Kukakavadzana pamusoro pekuti kana kuti kwete kuregedza yakakodzerwa vertebral joint
Mufananidzo 1 Schematic diagram yechimiro chekonotruncus, vertebral artery, uye musana uye nerve midzi.
a. Ukama pakati peiyo articular eminence ye concha uye vertebral artery.
b. Mubhuku racho, muganhu wepakati we articular eminence unobviswa, uye lateral edge inochengetedzwa zvakakodzera kuti irege kukuvadza kune vertebral artery.

Fig. 2 Schematic diagram ye nerve root compression uye decompression nekuparadzira hyperplastic conical joints.
a. Kukura kwepfupa uye kupera kwepelinha yezvibatanidza zvekonical kunoderedza nzvimbo ye-cross-sectional ye intervertebral foramina, nokudaro kumanikidzira midzi yetsinga.
b. Intervertebral fusion device / implant inogona kuzarura nzvimbo ye intervertebral kuti iwedzere nzvimbo ye intervertebral foramen uye inobata nerve root compression, uye panguva imwechete, kugadzirisa kugadzikana kwemusana.
Kudikanwa kwekuvhiyiwa kwe anterior cervical spine kubvisa hook vertebral joint yanga iri pfupa rekukakavara kubva pakatanga nzira.
Tsanangudzo yekutanga yeanterior cervical decompression uye implant fusion nekugadzirisa kwemukati yakapiwa naRobinson naSmith muna 1955 umo akatsanangura nzira yacho seisingadi kubviswa kwe leptokyphotic joint osteophyte. Cloward, mumwe muvambi weACDF, akasimbisa kuti kumanikidzwa kwese kunofanira kubviswa, uye kuti kubviswa kwakananga kwe hyperplastic leptokyphosis kwakakosha pakugadzirisa, asi Robinson akapindura kuti leptokyphosis inogona kugadziriswa sezvo kugadzikana kwemusana kwakasimbiswa uye sezvo maitiro asina kujairika emagetsi akanyangarika, uye kuti izvi zvisinganzwisisiki zvakafungidzirwa kuti zvakabatana neptokyphosis.
Vanochengetedza vanopikisa kuti hook yekubatanidza inobatsira 48% kusvika 60% yekugadzikana kwechikamu chimwe nechimwe uye inopa kugadzikana kukuru mumashure emusana wekervical spine, uye iyo yakajairwa cervical foraminotomy decompression decompresses posterior aspect of hook joint and the anterior aspect of the neuraastable, most part of the neuraxial, iyo inobviswa uye inobviswa. kusagadzikana pamwe nekutama kwenzvimbo yekusima kunoderedza kubudirira kweiyo fusion.
Kana mhedzisiro yekiriniki yakaenzana inogona kuwanikwa pasina kudzokororwa kweiyo hook vertebral joint, kuchengetedzwa kwehoko vertebral joint kunogona kupa theoretically kurongeka kwakakodzera kune yakakwirira fusion mazinga. Mukuwedzera, kuchengetedzwa kwehook vertebral joint kunobatsira kuderedza mikana ye postoperative vertebral subluxation, uye yakacherechedza kuti kana nzvimbo yehoko ye vertebral joint inogadziriswa neanopfuura 38%, chiyero che interbody fusion subluxation chichawedzera zvakanyanya.

Zvinoenderana neresection school of thought, anatomically, posterior wall of the leptospondylar joint is the anterior wall of the nerve root canal, uye bony residu kubva kune leptospondylar joint hyperplasia inogona kutungamirira kune intervertebral foraminal stenosis.
Muchiito chekiriniki yemazuva ano, kuora mwoyo nekubviswa kwe leptokyphosis kuchiri kukurudzirwa kune varwere vane kudzvinyirira kwakanyanya kwe leptokyphotic joint hyperplasia, kuitira kuti kusunungurwa kwetsinga kana vertebral artery nokukurumidza sezvinobvira.
Kakawanda, kukakavara kwakagara kuripo, asi kusarudzwa kwekuchengetedza, kuchengetedza zvishoma, kana kubvisa zvachose hook spondylolisthesis maererano nemamiriro emurwere yava kubvumirana mune zvakasiyana-siyana zvekliniki maitiro. Iyo yega yega nzira yekurapa, zvisinei, inoisa zvakanyanya kudiwa pahukuru hweiyo prosthesis.

Iyo SAGI 2-nail yekuvhara zero incision yakaderedzwa kusvika 14.8 mm muhupamhi, tichifunga nezve anatomical dimens yehuwandu hweChinese, uye inopa mutyairi kurapwa kwakasiyana-siyana kwemukati wejojo yehuku, zvichibvumira kurapwa kwejojo yehuku kusarudzwa zvinoenderana nemamiriro chaiwo omurwere, uku achivimbisa kugadzikana kwekutanga uye kwenguva refu fusion.
Postoperative spinal epidural hematoma
Spinal epidural hematoma (SEH) idambudziko risingawanzoitiki uye rakakomba mushure mekutanga kwekervical nzira, ine chiitiko chinenge 0.1% kusvika 0.2%.SEH inoitika muhupfumi hwevenous plexus ye epidural, iyo inotungamirira kumusana wakaoma wepinal cord kukanganiswa kwekushanda kana kuumbwa kwehematoma kusina kurapwa nenguva. Kuvhiyiwa kwechimbichimbi mushure mekuongororwa kweSEH kunogona kubatsira kudzoreredza basa retsinga.

Postoperative SEH schematic yeACCF
Spinal epidural haematomas inogoneka mushure mezvose ACDF neACCF, neACCF ine njodzi yakanyanya yehematomas nekuda kwekukuvadzwa kukuru uye kuwedzera kwemapfupa emapfupa; zvisinei, huwandu hwese hwemaitiro eACDF hwakakura, nehuwandu hwepamusoro hweSEHs huri kuitika.
Kudzivirirwa kweSEH mushure meanterior cervical approach inofanira kuenderera mberi munguva yose yeperioperative:
A. Kuongorora kusati kwaitwa kunofanira kupedzwa, uye kubvunzurudzwa kwakadzama kunofanira kuitwa pamusoro pokuti kune hosha ipi neipi yokugwinya, uye kana pane nhoroondo yokusvuta kwenguva refu nokunwa doro; kana pane vanhu vanotora anticoagulant zvinodhaka, vanofanira kurega kuatora kwevhiki imwe vasati vavhiyiwa;
B. Yakakwana intraoperative haemostasis, incomplete haemostasis ne electrocoagulation banga inogona kutungamirira pakubuda ropa kutsva, zvinokurudzirwa kushandisa bipolar electrocoagulation forceps; mukuita kwe vertebral body subtotal resection, pfupa wax inofanira kushandiswa kuti isapinda ropa rakawandisa kubva pamapfupa; kushandiswa kwemishonga yehemostatic, yakadai setranexamic acid jekiseni, nezvimwewo, kuitira kuderedza kubuda kweropa; hazvidikanwi kutsvaga kugadziriswa kwakakwana kwemashure ekureba kwenguva refu kwechikamu chinoshandiswa, uye kuchengetedza zvishoma zvishoma zvemashure longitudinal ligament pamativi maviri anogonawo kubudirira mugumisiro wekuderedza; kuiswa kweprosthesis kunofanira kusiya nzvimbo yakakwana kurudyi uye kuruboshwe kumativi. Pakuisa prosthesis, nzvimbo yakakwana inofanira kusara kuruboshwe uye kurudyi kumativi kuitira kuti kubuda ropa kwepidural kunogona kuyerera kumberi kwe vertebrae uye kubudiswa kuburikidza neakaipa pressure drainage tube;
