Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
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.
As a result of having congenital Klippel-Feil syndrome, the spinal anatomy of the individual will present abnormal fusion of any two of the seven cervical bones in the neck. [13] This is considered to be an anomaly of cervical bones. [14] It affects the functioning of cervical spinal nerves (C1 - C8) because of compression on the spinal cord.
Type II—Long fusion below C2 with an abnormal occipital-cervical junction. Similar to the C2-C3 fusion of McRae and could be viewed as a more elaborate variation. Flexion, extension, and rotation are all concentrated in the area of an abnormal odontoid process or poorly developed ring of C1 which cannot withstand the effects of aging.
The Hangman's fracture which is a fracture of the C2 vertebral body or dens of the cervical spine upon which the skull base sits to allow the head to rotate, can also be associated with atlanto-occipital dislocation. Despite its eponym, the fracture is not usually associated with a hanging mechanism of injury.

The atlas (C1) and axis (C2) are the two topmost vertebrae. The atlas (C1) is the topmost vertebra, and along with the axis forms the joint connecting the skull and spine. It lacks a vertebral body, spinous process, and discs either superior or inferior to it. It is ring-like and consists of an anterior arch, posterior arch, and two lateral masses.
As a result, Barsa and coauthors showed that the result of fracture fusion reduced after one year but only one patient died of other disease during the follow-up. [8] Hakalo and Wronski (2008) showed the benefits of operative treatment such as using transoral C2-C3 discectomy with plate-cage stabilization or posterior direct pars screw repair ...
