Cervicocranial syndrome or (craniocervical junction syndrome, CCJ syndrome) is a combination of symptoms that are caused by an abnormality in the cervical vertebrae leading to improper function of cervical spinal nerves. Cervicocranial syndrome is either congenital or acquired. Some examples of diseases that could result in cervicocranial ...
Craniocervical instability (CCI) is a medical condition characterized by excessive movement of the vertebra at the atlanto-occipital joint and the atlanto-axial joint located between the skull and the top two vertebra, known as C1 and C2. [citation needed] The condition can cause neural injury and compression of nearby structures, including the ...
Atlanto-occipital dislocation, orthopedic decapitation, or internal decapitation describes ligamentous separation of the spinal column from the skull base. It is possible for a human to survive such an injury; however, 70% of cases result in immediate death. It should not be confused with atlanto-axial dislocation, which describes ligamentous ...
A syrinx results when a watery, protective substance known as cerebrospinal fluid, that normally flows around the spinal cord and brain, transporting nutrients and waste products, collects in a small area of the spinal cord and forms a pseudocyst. A number of medical conditions can cause an obstruction in the normal flow of cerebrospinal fluid ...
Patients who exhibit extreme joint hypermobility and connective tissue weakness as a result of Ehlers–Danlos syndrome or Marfan syndrome are susceptible to instabilities of the craniocervical junction; thus they are at risk for acquiring a Chiari malformation. Headache, neck pain, unsteady gait usually during childhood [4] 1.5
articulatio atlantoaxialis mediana, articulatio atlantoaxialis lateralis. MeSH. D001268. FMA. 25524. Anatomical terminology. [edit on Wikidata] The atlanto-axial joint is a joint in the upper part of the neck between the atlas bone and the axis bone, which are the first and second cervical vertebrae. It is a pivot joint.
Cervicogenic headache is a type of headache characterized by chronic hemicranial pain referred to the head from either the cervical spine or soft tissues within the neck. [1] [2] The main symptoms of cervicogenic headaches include pain originating in the neck that can travel to the head or face, headaches that get worse with neck movement, and limited ability to move the neck.
In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine and is located in the neck. The bone is named for Atlas of Greek mythology, just as Atlas bore the weight of the heavens, the first cervical vertebra supports the head. [1] However, the term atlas was first used by the ancient Romans for the seventh cervical ...
