Nzira ye Odontoid, aka, iyo Dens
Izvozvo zvinoshandiswa, izvo zvinozivikanwawo semapango, ndezvokukwira kumusoro kwepfupa inomuka kubva kumativi epakati pekatikati yeedisb vertebra. (The axis ndiyo yechipiri chepamusoro-pfupa bone.)
Atlas ndiyo yekutanga pfupa rako; inogara pamusoro peiyo. (Dhehenya rinogara pamusoro peatlas.) Mapurojekiti aya anowanikwa munzvimbo yakakura muatlas, uye izvi ndizvo zvakaita mapfupa eatlantoaxial (atlanto inoratidzika neatlas, uye axial inosangana neane axis) yakabatana pamwe chete.
Kusiyana nedzimwe dzakawanda zvepentibrae yomumapapiro, atlas haina muviri wekupedzisira . Pane kudaro, ini ndakagadzirwa sechindori (sezvakataurwa pamusoro,) chiri mukati mukati, uye kuburikidza nekugadzirisa kwacho kunopera. Urongwa uhwu hunobvumira rusununguko rwakawanda rwekufamba pakati pekusanganiswa kwe musoro, kutanga vertebra (atlas), uye vertebra yechipiri (axis). Chaizvoizvo, sangano reatlantoaxial ndiyo inonyanya kushandiswa (uye yakaoma kwazvo) pamwe chete mumupendero.
Izvo zvinotadza zvinopa pivot point - inonzi axis of motion - iyo iyo dhehenya uye yekutanga kervical vertebra (maatlas) inotenderera, inokanganisa uye / kana kutendeuka (izvi chaizvoizvo chinhu chimwe chete.) Saka kana zvasvika pakushanduka musoro wako kuitira kuti iwe uone kumashure kwako, kana pari yakafanana, iwe unogona, kusvika pamwero wakawanda, tenda dens rako nokuda kweiyo. Misungo nezvimwe zvikamu mumutsipa zvinotorawo basa, asi izvi zvine chokuita pakati peganga, kutanga uye rechipiri vertebra zvinopa maitiro ekugadzirisa kuti aite.
Kukuvadza kuNzira yeOodontoid: Manyevero - Aya ndiwo Matambudziko Makakomba
Kukuvadza kwakasiyana kunogona kukanganisa mashizha, kusanganisira kushungurudzika kunokonzera kumusoro kweganga pasi, izvo zvingaita kuti mapepa aiswe muuropi. Izvi zvingangobvisa rufu.
Kushungurudzika kana kukuvadza kune mitsipa inobata kufamba kweatlantoaxial mukutarisa kunogona kukonzera mapepa, zvichiita kuti zvivhiringidze mutsara wepervical.
Izvi zvinogona kukonzera kuparara.
Kusiyana pakati peatlan neyosi. Ichi chinhu chakanyanya kuipa, chisingaoneki chinenge chichikuvadza mutsara wako. Kusununguka kunokonzerwa nekushaya hyperflexion.
Mimwe mhando yekukuvara kwegorosi inosanganisira kushungurudzika kana kutambanudza kunogona kukonzera kufamba kwakanyanyisa mubatanidzwa weanlantoaxial.
Uye mapepa anogona kuputsika, zvichidzika kumusoro, kumusoro kwayo pane axis kana pamuviri we-axis. Mitsetse inofungidzirwa sekukuvadza kwekuveura; dzimwe nguva vanoperekedza kusununguka uye dzimwe nguva kwete. Apo kusununguka kunopesana nekuputsika, maitiro omukono wako wepelinha yakasara akatsiga ari nani kupfuura pane imwe nyaya yekuparadzanisa pakati peatlasi uye inongo chete.
Maererano nekuongorora kwe2005 kwakabudiswa mumagazini inonzi Injury , zvinokanganisa fractures zvinokwana makumi maviri kubva muzana yezvose zvinokonzerwa nekervical fractures. Mimwe mhando yemakumbo emutsipa inosanganisira, asi haigumi ku: kuputsika kwevhu uye kuputika .
Vanyori vekudzidza kweku2013 kwakabudiswa mumagazini, Makliniki , inofungidzira kukanganisa kwekukuvara uku kuva zvishoma, pakati pe5% uye 15%.
Sezvambotaurwa pamusoro apa, mapapanho anoputika akarongerwa nekukwirira kwawo, iyo chinhu chinogona kufanotaura kufungidzira pamwe nekuona kurapa kwekukuvara.
- Tanga I: A fracture yepamusoro chikamu chekuita (icho chinonzi.).
- Rudzi rwechipiri: Kurwisana pamucheto wemhara.
- Rudzi rwechitatu: Kuputsika kunowanikwa mumuviri we-axis iri pasi peiyo.
Mishonga inogona kutora maitiro ekuvhiya kana kupfeka bhande. Iko, zvechokwadi, zvakanakisisa kutarisana neunyanzvi hwepfungwa dzako paunosarudza zvokuita maererano nekukuvara kwemapuranga, sezvo ichi chikukuvadza chakaoma munzvimbo yakaoma zvikuru.
Kurarama Nekukuvadza Kwemvura
Kukuvadza kumapako kunogona kuchinja zvikuru hupenyu hwako. Yu angafanirwa kuchinja kuhupenyu ari muwiricheya usiku hwose, somuenzaniso. Kana uchida kudzidza zvakawanda pamusoro pekuti vanhu vanotarisana sei nekukuvadzwa uku mumazuva avo ega, (uye mune kuchema zvakanaka iwe uripo) verenga bhuku rinonzi The Body Broken naLynne Greenberg.
