Basilar invagination can be present at birth. If the condition develops after birth, it is usually the result of injury or diseases. If due to injury, about half the time it is caused by vehicle or bicycle accidents; 25% of the time by falls and 10% of the time by recreational activities such as diving accidents.[citation needed]
If there are no neurological symptoms (such as difficulties moving, loss of sensation, confusion, etc.) and there is no evidence of pressure on the spinal cord, a conservative approach may be taken such as:[citation needed]
Medications, such as aspirin, without corticosteroids to relieve inflammation
Cervical traction, in which the neck is pulled along its length, thus relieving pressure on the spinal cord
Using a neck collar or cervical-thoracic suit
If there is pressure on the spinal cord or life-threatening symptoms are present, surgery is recommended.
