Inqubo ye-Odontoid, aka, i-Dens
Inqubo ye-odontoid, eyaziwa nangokuthi imifantu, iyisimo esiphezulu sesithambo esivela kusukela engxenyeni engaphambili ye-vertebra ye-axis. (I-axis yithemba lesi-2 eliphakeme kakhulu lomgogodla.)
I-atlas iyithambo lokuqala lentamo yakho; lihlezi phezu kwe-axis. (I-skull ihlezi phezulu kwe-atlas.) Amaprosesa ama-dens abe yindawo ephakathi e-atlas, futhi yilokho amathambo e-atlantoaxial (i-atlanto ehlobene ne-atlas, futhi i-axial ihlobene ne-axis bone) ehlangene ndawonye.
Ngokungafani namanye ama-vertebrae omgogodla, i-atlas ayinayo umzimba we- vertebral . Esikhundleni salokho, ngifakwe njengendandatho yokuthi (njengoba kushiwo ngenhla,) ingaphakathi phakathi, futhi lapho inqubo ephikisayo idlula khona. Leli lungiselelo livumela inkululeko enkulu yokuhamba phakathi kwenhlanganisela yekhanda, i-vertebra yokuqala (i-atlas), ne-vertebra yesibili (i-axis). Eqinisweni, ukuhlanganiswa kwe-atlantoaxial yiyona inhlanganisela yeselula (futhi eyinkimbinkimbi kunazo zonke) ehlangene nomgogodla.
Inqubo ye-odontoid inikeza iphuzu le-pivot - elibizwa ngokuthi i-axis of motion - lapho i-skull ne-vertebra yokuqala yomlomo wesibeletho (i-atlas) ijika, ijika futhi / noma ijika (lokhu kuyizinto ezifanayo ngempela.) Ngakho uma kuziwa ekuphenduleni ikhanda lakho ukuze ubone ngemuva kwakho, noma epaki elifanayo, ungakwazi, ngokukhulu kakhulu, ukubonga amathini akho ngalokho. Imisipha nezinye izitho entanyeni zidlala indima futhi, kepha lokhu okuhlangene phakathi kwe-skull, i-vertebra yokuqala neyesibili inikezela ukuthi i-mechanics engezansi yenzeke.
Ukulimala eNqubo Ye-Odontoid: Isexwayiso - Lokhu Kulimala Kakhulu
Ukulimala okuningana kungathinta imifantu, kufaka phakathi ukuhlukumezeka okuqhuma phezulu kwe-skull phansi, okungase kubangele ukuthi amaphoyinti agxilwe ebuchosheni. Lokhu kungabangela ukufa.
Ukucindezeleka noma ukulimala kumigogodla ebamba ukuhamba kwe-atlantoaxial esheke kungaphazamisa imijondolo, okuyivumela ukuba iphazamise umgogodla wesibeletho.
Lokhu kungabangela ukukhubazeka.
Ukuhlukanisa phakathi kwe-atlas kanye ne-axis. Lokhu ukulimala okungathí sina, okungavamile okungenani kuyolimaza intambo yomgogodla. Ukuhlukaniswa kokulimala ukulimala kwe-hyperflexion.
Ezinye izinhlobo zokulimala komgogodla zihlanganisa ukucindezeleka noma ukwelula okungase kubangele ukunyakaza ngokweqile kuhlangene ne-atlantoaxial.
Futhi amaphoyinti angahle aphulwe, mhlawumbe endaweni ephezulu, esisekelweni saso ku-axis noma emzimbeni we-axis. Ukucatshangwa kubhekwa njengokulimala kwamakhanda; ngezinye izikhathi bahambisane nokuhlukaniswa kanye nezinye izikhathi hhayi. Uma ukuxoshwa kuhambisane nokuphuka, izinkinga zomgogodla wakho ohlala ungcono zingcono kunalokho uma kwenzeka ukuhlukaniswa phakathi kwe-atlas kanye ne-axis kuphela.
Ngokwenhlolovo ka-2005 eyanyatheliswa encwadini ethi Injury , i-odontoid fractures ilandisa cishe cishe ngu-20% yazo yonke imifucu yomlomo wesibeletho. Ezinye izinhlobo zezintambo zezintambo zifaka phakathi, kodwa azikhawulelwanga ku: ukuphuka kwesibhulodi sobumba nokuphuka komgwaqo olula .
Abalobi be-2013 yocwaningo eshicilelwe emaphephandabeni, emitholampilo , balinganisela ukuthi lesi silimazi sincane kakhulu, phakathi kuka-5% no-15%.
Njengoba kushiwo ngenhla, ama-fracture amaphoyinti ahlukaniswe ukuphakama kwawo, okuyisici esingahle sichaze ukubikezela kanye nokunquma ukwelashwa kokulimala.
- Thayipha I: Ukuphuka kwengxenye engenhla yenqubo (ithiphu.)
- Uhlobo lwesibili: I-Fracture engxenyeni yamasongo.
- Uhlobo lwe-III: I-fracture eyenzeka emzimbeni we-axis obangelwa phansi.
Ukwelashwa kungathatha uhlobo lokuhlinzwa noma ukugqoka isongo. Yiqiniso, kungcono kakhulu ukubonisana nomchwepheshe wakho wezinsipho lapho unquma ukuthi uzokwenzenjani ngokulimala kwamasongo, ngoba lokhu kuyingozi ukulimala endaweni encane kakhulu.
Ukuphila ngokulimala kwama-Dens
Ukulimala emaphoyiseni kungashintsha kakhulu impilo yakho. I-Yu kungenzeka ukuthi ivumelane nokuphila esihlalweni sabakhubazekile ngobusuku bonke, isibonelo. Uma ungathanda ukufunda kabanzi mayelana nokuthi abantu babhekana kanjani nalokhu ukulimala ekukholweni kwabo usuku nosuku, (futhi ukhale kahle lapho ukhona) funda incwadi ethi The Body Broken nguLynne Greenberg.
