Njira ya Odontoid, aka, Dens
Njira yokhala ndi phokoso, yomwe imadziŵikanso kuti imenje, imakhala ndi fupa lamthambo limene limachokera kutsogolo kwa pakati pa axis vertebra. (The axis ndi 2 apamwamba fupa lamphongo.)
Atolo ndilo fupa loyamba la khosi lako; ilo limakhala pamwamba pa axis. (Chigaza chimakhala pamwamba pa atlas.) Mapulani a malowa amakhala pakatikati pa malo a atlas, ndipo momwemonso mafupa a atlantoaxial (atlanto akukhudzana ndi atlas, ndipo axial ikugwirizana ndi fupa la axis).
Mosiyana ndi mavitamini ena a msana, ma atlas alibe thupi lakumtunda . M'malo mwake, ndimapanga ngati mphete (monga tanenera pamwambapa,) ndipakatikatikati, ndipo kudzera mwachinthucho chimakhala chodabwitsa. Makonzedwe ameneŵa amalola ufulu wambiri wa kuyenda pakati pa kuphatikiza mutu, yoyamba vertebra (atlas), ndi 2 vertebra (axis). Kwenikweni, mgwirizano wa atlantoaxial ndi wothandizira kwambiri (komanso ovuta kwambiri) kuphatikizapo msana.
Ndondomeko yotereyi imapereka mfundo yofunika kwambiri - yomwe imatchedwa kuyenda mozungulira-kumene chigaza ndi chiberekero choyamba chotchedwa vertebra (ma atlas) chimasinthasintha, kupotoza ndi / kapena kutembenuka (izi ziri chinthu chimodzimodzi.) Kotero zokhudzana ndi kutembenuka mutu wanu kotero kuti mukhoze kuwona kumbuyo kwanu, kapena paki yofanana, mutha kutero, ndikuthokozani mapensiti anu. Minofu ndi ziwalo zina m'khosi zimagwira ntchito bwino, koma izi zimagwirizana pakati pa galasi, yoyamba ndi yachiwiri vertebra imapereka makina oyendetsera kuti zowonongeka zichitike.
Kuvulala kwa Njira ya Odontoid: Chenjezo - Izi ndi Zovulala Zoopsa
Kuvulala kochuluka kungakhudze mitsempha, kuphatikizapo zoopsa zomwe zimaponyera pamwamba pa gazi pansi, zomwe zingachititse kuti mapiko akankhidwire mu ubongo. Izi zikhoza kupha imfa.
Kupsinjika maganizo kapena kuvulala kwa mitsempha yomwe imayendetsa kayendedwe ka atlantoaxial mu cheke ikhoza kuthetsa mitsempha, kuti iwononge msana.
Izi zingachititse kufooka.
Kusiyana pakati pa ma atlasi ndi axis. Ichi ndi chovulaza choopsa kwambiri, chomwe chingasokoneze msana wako. Kuthamangitsidwa ndi kuvulala kwa hyperflexion.
Mitundu ina ya kuvulala kwa mitsempha imaphatikizapo kupanikizika kapena kutambasula zomwe zingayambe kuyenda mofulumira mu mgwirizano wa atlantoaxial.
Ndipo ming'alu imatha kuphwanyidwa, kaya pamwamba pamtunda, pamunsi pazitali kapena pamtundu wa axis. Zikuoneka kuti fractures ndi vuto lovulaza; nthawi zina amatsagana ndi nthawi zina osati. Pamene kusinthana kumaphatikizapo kutaya, mitsempha ya msana wanu imakhala yabwino kuposa momwe zimakhalira pakati pa ma atlasi ndi phokoso lokha.
Malinga ndi kafukufuku wina wa 2005 umene unalembedwa m'nyuzipepala yotchedwa Injury , mafupa osokoneza bongo amachititsa pafupifupi 20 peresenti ya fractures yonse ya chibelekero. Mitundu ina ya mitsempha ya khosi imaphatikizapo, koma siimangokhala : kuphulika kwadothi ladothi ndi kuphwanyidwa kosavuta .
Olemba a 2013 omwe adafalitsidwa mu nyuzipepala, Amakliniki , amalingalira kuti chiwopsezo ichi chachepa kwambiri, pakati pa 5% ndi 15%.
Monga tafotokozera pamwambapa, fractures imatuluka ndi kutalika kwake, zomwe ndizo zomwe zingagwiritsire ntchito chithunzithunzi cha matendawa komanso kuwonetsa chithandizo cha chovulalacho.
- Lembani I: Kutaya kwa gawo la pamwamba (ndondomeko.)
- Mtundu Wachiwiri: Kuphwanyidwa pansi pa makoswe.
- Mtundu Wachitatu: Kutsekeka kumene kumachitika m'thupi lazomwe zimayendetsa mitsempha.
Chithandizo chingatenge mawonekedwe a opaleshoni kapena kuvala nsalu. Ndizowona bwino kuti mufunsane ndi katswiri wanu wa msana posankha zoyenera kuchita pangozi yamisala, chifukwa ichi ndi chovulaza chovuta kumalo ovuta kwambiri.
Kukhala ndi Kuvulaza Kwambiri
Kuvulala kumabenje kungasinthe kwambiri moyo wanu. Yu amafunika kusintha moyo wake ali pa chikuku usiku uliwonse, mwachitsanzo. Ngati mukufuna kudziwa zambiri za momwe anthu akulimbirana ndi vutoli tsiku ndi tsiku kukhalapo, (ndi kulira mokondwera pamene mulipo) werengani buku lakuti Body Broken ndi Lynne Greenberg.
