Iyo musana wepamuviri ndiyo mhango yakavharira musana wepelinha pamoyo pemuzongoza. Inogona kunge iri nzvimbo yezvironda zvemhando dzakasiyana siyana, zvichikonzera musana wekupwanya compression zvichikonzera kurwadziwa, mota uye nekunetseka kwekunzwa.

Iyo medullary canal, inonziwo medullary mhango, ndiyo mhango iri muzongoza ine musana wesipinha.

Sechiyeuchidzo, rwonzi rwepelinha, kana musana wesipinha, chikamu chepakati sisitimu yetsinga. Kuwedzera kwehuropi, tambo iyi ingangoita masentimita makumi mana inobvumira kufambiswa kweruzivo pakati pehuropi nemuviri, kuburikidza nemitsipa yemusana iyo inobuda mairi kuburikidza nemakomba ekubatana.

Iyo medullary canal inovhara uye inodzivirira musana wesana.

Spinal tambo kudzvinyirira

Isu tinotaura nezvepasipinha tambo yekumanikidza kana rwonzi rwepelinha uye tsinga dzinoparadzaniswa nazvo dzinomanikidzwa nekukuvara. Iko kumanikidza kunozokonzeresa kurwadziwa kumusana, kupisa mwenje uye mune dzakakomba zviitiko zvemota, sensory uye sphincter kusagadzikana.

Chironda chinokonzera kudzvinyirira chinogona kuwanikwa kunze kwemuzongoza (extramedullary lesion) kana mukati (intramedullary lesion) uye uve, zvichienderana nehunhu hwayo, hwakasimba kana husingaperi. Zvinogona kuva:

• dhizaini yeherniated 
• subdural kana epidural hematoma ichitevera kushungurudzika kwakatungamira kune ligament kana kukuvara kwepfupa, kubvamburwa kwechiuno, kutora anticoagulant
• kutsemuka, kumanikidzika kwechipfuva nezvidimbu zvemapfupa, kutsemuka kwemutsipa kana kuderedzwa
• bundu (kunyanya metastatic extramedullary bundu)
• meningioma, neuroma
• pute
• kudzvinyirira pfupa nekuda kweosteoarthritis
• kukanganisa kwakanyanya
• cervicarthrosis myelopathy

Cauda Equina Syndrome

Iyo nzvimbo yespinal cord iri padanho rekupedzisira lumbar vertebrae uye iyo sacrum, uye kubva iyo inobuda mizhinji mitsipa midzi yakabatana nemazasi emakumbo uye sphincters, inonzi ponytail.

Kana rwonzi rwepelinha kumanikidza kunogara padanho reiyi ponytail, kazhinji kazhinji nekuda kweiyo herniated disc, inogona kutungamira kune cauda equina syndrome. Izvi zvinoratidzirwa nekurwadziwa kwepashure kwekurwadziwa, kurwadziwa munzvimbo yeparineum uye nemumakumbo ezasi, kurasikirwa kwekunzwa, kuonda mitezo uye kusagadzikana kwesphincter. Ichi chiitiko chekurapa. 

Iyo medullary infarction

Kazhinji, ronda racho panotangira musana wekupwanya compression rinodzora iyo arterial vascularization, zvobva zvaendesa kune medullary infarction.

Surgery

Kuvhiya ndiko kurapwa kwakazara kwepasipera tambo yekumanikidza. Kupindira, kunonzi laminectomy, kunosanganisira kubvisa iyo yepashure chikamu cheiyo vertebra (kana blade) padhuze nechironda, wozoibvisa kuitira kudzikamisa mwongo nemidzi yawo. Kupindira uku zvakare kunoita kuti zvive nyore kuongorora iyo lesion.

Muchiitiko che cauda equina syndrome, kuvhiyiwa kwekudzikisira kunofanira kuitika nekukurumidza kuitira kudzivirira mota dzakakomba, kunzwa, sphincter uye sequelae yebonde.

Kana chironda ichi chinoita kuti musana wespinha udzvinyirire ihematoma kana bundu, izvi zvichavhiyiwa.

Radiotherapy

Mukana wechirwere chegomarara, radiotherapy dzimwe nguva inosanganiswa nekuvhiyiwa.

Kuongororwa kwekiriniki

Wakatarisana nemotor, sensory, sphincter kana kamwe kamwe kutanga kurwadziwa shure, zvakakosha kubvunza pasina kunonoka. Nyanzvi ichatanga kuita ongororo yekiriniki kutungamira kuongororwa kunoenderana nezviratidzo uye palpation yemuzongoza.

MRI

MRI ndiyo yegoridhe muyero wepelinha. Izvo zvinoita kuti zvikwanisike kuwana saiti yeiyo musana tambo compression uye kunanga kune yekutanga kuongororwa nezve hunhu hwechironda. Zvichienderana nechiratidzo chebvunzo, jekiseni reGadolinium rinogona kuitwa.

CT myelography

Kana MRI isingaite, CT kana CT myelography inogona kuitwa. Uku kuongorora kunosanganisira kubaya chigadzirwa chinogonesa mumupendero musana kuitira kuti utarise mitsara yemutsipa wepelinha pama x-ray.

Muzongoza X-ray

Kana pfupa lesion rikafungidzirwa, X-ray yemuzongoza inogona kutorwa mukuwedzera kune iyo MRI.

Medullary arteriography

Mune zvimwe zviitiko, arteriography inogona kuitwa kuti utsvage zvinogona kuitika vascular lesion. Inosanganisira kubaya jekiseni, pasi peanesthesia yemuno, chigadzirwa chakapesana chobva chatora akateedzana emifananidzo panguva yeanopararira uye ane hutachiona zvikamu zveichi chigadzirwa.
