What is an upper cervical injury and how does it occur?
An upper cervical injury is a trauma, accident, injury, or even a simple fall or blow to the head, which causes an occipital-atlantal-axial subluxation . It is not necessarily an event that you would remember nor may it cause any immediate symptoms. This is the reason why even those who appear to be in good health should be screened for an occipitap-atlantal-axial subluxation from a past upper cervical injury.
