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 ...
Midline shift (arrow) is present in this brain after a stroke (infarct depicted in shaded area). Midline shift is a shift of the brain past its center line. [1] The sign may be evident on neuroimaging such as CT scanning. [1] The sign is considered ominous because it is commonly associated with a distortion of the brain stem that can cause ...
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
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 ...
Atlas (anatomy) 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 ...
Type II: Occipital basilar skull fracture extending into the condyle, resulting from direct trauma. The craniocervical junction usually stays stable, but neurologic injury may occur from the blow to the head. Type III: Isolated avulsion of the condyle with displacement towards the alar ligament, due to forced rotation / lateral bending. This ...
