Mugero wakagadzira juxtaposition yechikamu chisina chinhu che vertebrae, musana wemusana une musana uye tsinga. Dzimwe nguva inodzikira, zvichikonzera kudzvanywa kwemaitiro etsinga.

Muzongoza, kana musana, wakaumbwa nemurwi we33 vertebrae: 7 cervical vertebrae, 12 dorsal (kana thoracic) vertebrae, 5 lumbar vertebrae, sacrum inoumbwa ne5 fused vertebrae uye pakupedzisira coccyx inoumbwa ne4 vertebrae. Iyo vertebrae inobatanidzwa ne vertebral disc.

Imwe neimwe vertebra ine kumashure kwayo arch, kana orifice. Yakaiswa pamusoro peumwe neumwe, aya vertebral arches anoumba mugero: ndiyo musana wepinini, unonziwo spinal canal, ine musana uye tsinga pakati payo.

Mutsipa wepelinha unotangira kubva kune yekutanga cervical vertebra kusvika kune yechipiri lumbar vertebra. Inopera pamwero wechipiri lumbar vertebra ine dural sac iyo ine mota uye sensory nerve midzi yemakumbo uye dundira uye rectal sphincters. Nzvimbo iyi inonzi ponytail.

The musana canal inotsigira uye inodzivirira musana. Mukati memugero uyu wakaumbwa nemuzongoza, musana unodzivirirwa nemameninges akasiyana: dura mater, arachnoid uye pia mater.

Narrow lumbar canal kana lumbar canal stenosis

Mune vamwe vanhu, nekuda kwekupfeka kwechisikigo uye kubvarura (osteoarthritis), kune kupfupika kwehupamhi hwepinal canal pamwero we lumbar vertebrae, kureva, muzasi kumashure, pamusoro pe sacrum. Kungofanana nemajoini ese emuviri wemunhu, majoini e vertebrae ari pasi peiyo osteoarthritis iyo inogona kutungamirira ku deformation yavo nekukora kwejoint capsule kusvika pakukuvadza canal. Iyo lumbar canal, inowanzoita triangular muchimiro, inozotora yakamanikana T-shape, kana kutova nyore kutsemuka. Isu tinobva tataura nezve yakamanikana lumbar canal, lumbar canal yakatetepa mune ichiri stenosis ye degenerative lumbar canal. The stenosis inogona kungokanganisa lumbar vertebrae L4 / L5, apo mugero watova, pahwaro, nhete, kana pakaitika yakakura stenosis, mamwe vertebral pasi (L3 / L4, L2 / L3 kana kunyange L1 / L2).

Iyi stenosis inokonzera kudzvinyirirwa kwetsinga mumugero wepelinha zvichikonzera kurwadziwa kunowanzotsanangurwa se "kupisa" mumusana wezasi, nekuvhenekera mumagaro nemakumbo (neurogenic claudication).

Marwadzo aya ane hunhu hwekuwedzera nekufamba kana mushure mekumira kwenguva refu. Inodzikama kana wakazorora, dzimwe nguva ichipa nzira yekuve nechiveve kana masvosve (paresthesia).

Dzimwe nguva iyi lumbar canal idiki kubva pakuzvarwa. Izvi zvinodaidzwa kunzi Constitutional narrow lumbar canal.

Cauda equina syndrome

Iyo cauda equina syndrome inoreva seti yekusagadzikana kunoitika panguva yekutsikirira kwetsinga midzi iri kuzasi kwemusana, panzvimbo iyi inonzi cauda equina. Iyo mota uye yekunzwa tsinga midzi yemakumbo uye dundira uye rectal sphincters iri kumanikidzwa, kurwadziwa, kunzwa, mota uye genitosphincteric kusagadzikana zvinobva zvaonekwa.

Lumbar canal stenosis

Mutsara wekutanga wekurapa mishonga uye inochengetedza: analgesics, anti-inflammatory drugs, rehabilitation, kunyange corset kana kupinda mukati.

Muchiitiko chekukundikana kwekurapa zvinodhaka, uye apo kurwadziwa kunowedzera kukanganisa zuva rega rega kana lumbar canal stenosis inotungamirira kuparalyzing sciatica, nemakumbo emakumbo kana kukanganiswa kweurinary, kuvhiyiwa kuchapiwa. A laminectomy kana tambo yemusana inosunungurwa ichabva yaitwa, kuvhiyiwa kunosanganisira kubvisa vertebral lamina (posterior part of the vertebral) kuitira kusunungura tambo yemusana yakamanikidzwa ne stenosis. Rimwe kana mamwe mazinga anogona kushandiswa.

Cauda equina syndrome

Cauda Equina Syndrome idambudziko rekurapa rinoda kurapwa nekukurumidza kudzivirira zvakakomba sequelae. Corticosteroid therapy inogona kupihwa kuti ibvise marwadzo isati yaitwa neurosurgery. Izvi zvinovavarira kudzikisa tsinga midzi, kungave nekubviswa kwehuwandu hunoimanikidza (a herniated disc kazhinji, kashoma bundu), kana ne laminectomy.

Kuti uongorore spinal stenosis, zvidimbu-zvikamu zvemuzongoza zvinogadzirwa uchishandisa CT scan kana MRI. Iyo mifananidzo icharatidza yakakora vertebral bone pamutengo wepinal canal.

Kuongororwa kwekliniki kunoita kuti zvibvirire kuita chirwere chekutanga che cauda equina syndrome, yakasimbiswa neMRI yakaitwa nokukurumidza.
