atlantoaxial

pertaining to the atlas and axis.

atlantoaxial joint
the articulation between the first two cervical vertebrae.
atlantoaxial membrane
the fibrous sheet which closes the interarcual space between the atlas and the axis.
atlantoaxial subluxation
degeneration or malformation of the dens is seen mainly in toy breeds of dogs predisposing to displacement of the axis. Fracture of the dens can occur in any animal. Compression of the cervical cord is a common sequel that causes neck pain and varying degrees of spastic tetraparesis. Treatment is surgical stabilization. Also reported in Holstein cattle.

The craniocervical junction functions as one joint with complex mechanics, and because half of the rotational motion in the cervical spine occurs at the atlantoaxial junction, the joint relies disproportionately on ligamentous integrity.
During posterior cervical spine surgery, most cases of vertebral artery injury occur during the C1-C2 transarticular screw fixation procedure for atlantoaxial instability secondary to the proximity of the artery and the blind passage of a guiding wire or transarticular screw into the C1-C2 facet joint (16-19).
