Umhubhe wakha i-juxtaposition yengxenye engenalutho yama-vertebrae, umsele womgogodla uqukethe umgogodla nezinzwa. Ngezinye izikhathi iyancipha, ibangele ukucindezelwa kwezakhiwo zezinzwa.

Umgogodla, noma umgogodla, wenziwe isitaki sama-vertebrae angu-33: ama-vertebrae angu-7, ama-vertebrae angu-12 (noma i-thoracic), ama-vertebrae angu-5, i-sacrum eyakhiwe ngama-vertebrae angu-5 ahlanganisiwe futhi ekugcineni i-coccyx eyakhiwe ngama-vertebrae angu-4. Ama-vertebrae axhunywe yi-vertebral disc.

I-vertebra ngayinye engxenyeni yayo engemuva ine-arch, noma i-orifice. Ehlanganiswe phezu komunye nomunye, lawa ma-arches ama-vertebral akha umhubhe: umsele womgogodla, obizwa nangokuthi umsele womgogodla, oqukethe intambo yomgogodla kanye nezinzwa phakathi nendawo.

Intambo yomgogodla isuka ku-vertebra yokuqala yomlomo wesibeletho iye kweyesibili i-lumbar vertebra. Iphela ezingeni lesibili le-lumbar vertebra ene-dural sac equkethe izimpande zenzwa ye-motor kanye nezinzwa zemilenze kanye nesinye kanye ne-rectal sphincters. Le ndawo ibizwa nge-ponytail.

Umsele womgogodla usekela futhi uvikele umgogodla. Ngaphakathi kwalo mhubhe owenziwe ngumgogodla womgogodla, umgogodla uvikelwe ngama-meninges ahlukahlukene: i-dura mater, i-arachnoid kanye ne-mater efanayo.

I-lumbar canal stenosis emincane noma i-lumbar canal stenosis

Kwabanye abantu, ngenxa yokuwohloka kwemvelo nokudabuka (i-osteoarthritis), kukhona ukuncipha kobubanzi bomsele womgogodla ezingeni le-vertebrae yenyonga, okungukuthi, emhlane ongezansi, ngaphezu kwe-sacrum. Njengawo wonke amalunga omzimba womuntu, amalunga e-vertebrae empeleni angaphansi kwe-osteoarthritis engaholela ekuguqulweni kwawo ngokuqina kwe-capsule ehlangene ukuze kulimaze umsele. I-lumbar canal, evamise ukuba ngunxantathu, izobe isithatha umumo ka-T owumngcingo, noma ibe wumkeko olula. Sibe sesikhuluma ngomsele we-lumbar omncane, umsele we-lumbar oncishisiwe ku-stenosis ye-lumbar ewohlokayo. I-stenosis ingathinta kuphela i-lumbar vertebrae L4 / L5, lapho umsele usuvele, phansi, uncane, noma uma kwenzeka kuba ne-stenosis ebanzi, amanye ama-vertebral floor (L3 / L4, L2 / L3 noma ngisho ne-L1 / L2) .

Le stenosis ibangela ukucindezelwa kwemizwa emgodini womgogodla okuholela ebuhlungu obuvame ukuchazwa ngokuthi "ukusha" emhlane ongezansi, ngemisebe ezinqeni nasemilenzeni (i-neurogenic claudication).

Lezi zinhlungu ziba zimbi kakhulu ngokuhamba noma ngemuva kokuma isikhathi eside. Iyancipha lapho uphumule, ngezinye izikhathi ivumela ukuba ndikindiki noma izintuthwane (paresthesia).

Kwesinye isikhathi le canal ye-lumbar incane kusukela ekuzalweni. Lokhu kubizwa ngokuthi umsele we-lumbar omncane womthethosisekelo.

Cauda equina syndrome

I-cauda equina syndrome isho isethi yezinkinga ezenzeka ngesikhathi sokucindezelwa kwezimpande zezinzwa ezisezansi emuva, kule ndawo ebizwa nge-cauda equina. Izimpande ze-motor ne-sensory nerve yemilenze kanye nesinye kanye ne-rectal sphincters ezicindezelwayo, ubuhlungu, izinzwa, i-motor kanye ne-genitosphincteric disorders bese kuvela.

I-Lumbar canal stenosis

Ukwelashwa komugqa wokuqala kuyimithi kanye ne-conservative: ama-analgesics, izidakamizwa ezilwa nokuvuvukala, ukuvuselela, ngisho ne-corset noma ukungena.

Uma kwenzeka ukwehluleka kokwelashwa kwezidakamizwa, futhi lapho ubuhlungu bukhubaza kakhulu nsuku zonke noma i-lumbar canal stenosis iholela ku-sciatica ekhubazekile, ngokukhubazeka kwezinyawo noma ukuphazamiseka komchamo, kuzohlinzekwa ukuhlinzwa. I-laminectomy noma ukukhululwa komgogodla kuyobe sekwenziwa, ukuhlinzwa okuhlanganisa ukukhipha i-lamina ye-vertebral (ingxenye engemuva ye-vertebral) ukuze kukhululwe umgogodla ocindezelwe yi-stenosis. Ileveli eyodwa noma ngaphezulu ingasebenza.

Cauda equina syndrome

I-Cauda Equina Syndrome iyisimo esiphuthumayo sezokwelapha esidinga ukwelashwa ngokushesha ukuze kugwenywe ukulandelana okungathí sina. I-Corticosteroid therapy ingase inikezwe ukuze kudambise ubuhlungu ngaphambi kokuhlinzwa kwe-neurosurgery. Lokhu kuhloswe ukwehlisa impande yezinzwa, noma ngokususa isisindo esisicindezelayo (i-herniated disc kaningi, okungavamile ukuba isimila), noma nge-laminectomy.

Ukuxilonga i-stenosis yomgogodla, izigaba eziphambanayo zomgogodla zenziwa ngokusebenzisa i-CT scan noma i-MRI. Izithombe zizobonisa ithambo le-vertebral eliqinisiwe ngezindleko zomgogodla womgogodla.

Ukuhlolwa komtholampilo kwenza kube nokwenzeka ukwenza ukuxilongwa kokuqala kwe-cauda equina syndrome, okuqinisekiswa yi-MRI eyenziwa ngokuphuthumayo.
