What is craniocervical junction abnormalities?

Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord.

What is normal craniocervical junction?

The atlantodental interval (ADI) is a measurement used to evaluate the atlanto-axial relationship. This distance, described by Hinck et al,6 is conventionally held to be normal when it is less than 3 mm in men and 2.5 mm in women.

What is cranio cervical tumor?

Craniocervical tumors are tumors that can be found where the skull and neck meet, particularly the area of the foramen magnum (the opening at the base of the skull through which the spinal cord and the brainstem pass).

How is Craniocervical instability treated?

Treatment. Conservative treatment of craniocervical instability includes physical therapy and the use of a cervical collar to keep the neck stable. Cervical spinal fusion is performed on patients with more severe symptoms.

How is craniocervical instability treated?

Can tight neck muscles affect blood flow to brain?

Even a small misalignment can be the start of serious problems. When contracted muscles knot up in your neck, they reduce blood and oxygen circulation to your brain. Your brain uses almost one fourth of your body’s blood supply at any given time, so when the blood vessels to your head are constricted, you feel it.

Is Craniocervical instability serious?

The impact of craniocervical instability can range from minor symptoms to severe disability, with some patients being bed-bound. The constellation of symptoms caused by craniocervical instability has been labelled the cervico-medullary syndrome.

Can Craniocervical instability be cured?

Cervical instability is a medical condition in which loose ligaments in your upper cervical spine may lead to neuronal damage and a large list of adverse symptoms. If you have cervical instability, you may be experiencing migraines, vertigo, or nausea. Fortunately, this condition is treatable, though not curable.

Can a bone tumor develop at the craniocervical junction?

If tumors spread to the bones of the neck, the first two spinal bones may become misaligned. A rare, slow-growing bone tumor (called a chordoma) can develop at the craniocervical junction and press on the brain or spinal cord.

What kind of surgery is needed for craniocervical junction?

To relieve pressure on the brain, spinal cord, or nerves, doctors use traction or manipulate the head, then immobilize the neck. Surgery is sometimes needed. The craniocervical junction consists of the bone that forms the base of the skull (occipital bone) and the first two bones in the spine (which are in the neck): the atlas and axis.

How does craniocervical junction disorder affect your eyes?

Craniocervical Junction Disorder. Pressure on parts of the brain or cranial nerves (which connect the brain directly to various parts of the head, neck and trunk) can affect eye movements. People may have double vision or be unable to move their eyes in certain directions, or the eyes may move involuntarily.
