This is chronic fatigue, and it is one of the common symptoms associated with craniocervical instability. [53] Screw and rod fixation methods have lower complication rates and higher rates of successful fusion. Traditional conservative treatments for CCI include rest, pain management, upper cervical chiropractic treatment, and bracing with a cervical collar. 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. Diagnosing craniocervical instability involves 7 main criteria which include: Understanding how and when the injury occurred is important. But CCI really should refer to the movement of the skull with respect to the spine. Its name reflects the fact that it looks like a smaller version of the cerebrum.

In CCI the ligamentous connections of the craniocervical junction can be stretched, weakened or ruptured. [14] OCF is a surgery that aims at a biomechanical stabilization of the craniocervical junction. Pain is typically localized at the base of the skull and aggravated with flexion and rotation. Every Chiari patient should be aware of hereditary connective tissue disorders and the signs and symptoms of Craniocervical Instability and Basilar Invagination. Craniocervical instability (CCI) occurs when the craniocervical junction at the base of the brainstem becomes 'shaky'. The purpose of this study was to investigate the influence AS has on various radiologic parameters used to detect traumatic and degenerative . The common symptoms of CCI can also arise from different clinical conditions. [3] It can be brought on by a trauma, frequently whiplash; laxity of the ligaments surrounding the joint; or other damage to the surrounding connective tissue.

Craniocervical Instability (CCI) is a medical condition where the strong ligaments that hold your head to your upper neck are loose or lax. Any movement in the cervical vertebra can affect your body and lead to plenty of uncomfortable and nagging symptoms. A subset of patients can develop clinical instability of the craniocervical junction associated with pain and neurological dysfunction, potentially warranting treatment with occipitocervical fixation (OCF).

Eye movements in patients with Whiplash Associated Disorders: a systematic review. Why? Henderson FCS, Francomano CA, Koby M, Tuchman K, Adcock J, Patel S (2019) Cervical medullary syndrome secondary to craniocervical instability and ventral brainstem compression in hereditary hypermobility connective tissue disorders: 5-year follow-up after craniocervical reduction, fusion, and stabilization. However, three measurements are most commonly used: the Grabb-Oakes line, which measures ventral brainstem compression; the Clivo-Axial Angle (CXA), which measures brainstem deformity by the odontoid process; and the Basion Dens Interval, which measures vertical instability (cranial settling). It also helped me understand the corrective procedures needed. Likewise, the atlantoaxial joint [the articulation between C1 (atlas) and C2 (axis)] accounts for about half of the cervical spines ability to rotate the head. [44][45][46] Others have argued that these radiological measurements are "not accepted internationally as indicating instability. Dizziness or imbalance is a feature related to the fact that the upper neck is a major contributor to balance (4). Excessive movement between your head and neck can cause movement and damage of upper cervical facet joints, discs, nerves, and blood vessels.
