I'm in pain 24/7. I recive no help here in Norway, and I have to get surgery in Barcelona.
Atlantoaxsial instability (AAI):
Atlantoaxial instability means increased range of motion between the first and second cervical vertebrae. First swirl units atlas (c1) and carries the weight of the head, the second swirl units axis (c2) and is responsible for the rotation. Damage to the cartilage, ligaments, membranes and joint capsules allows the head, atlas and axis are not kept sufficiently in place.
Just a few degrees wrong position or movement can put pressure on the brainstem and give rise to an incredible array of symptoms.
Damage to the dens-axis:
Left-scarred structural changes in ligaments Alaria. These are connecting the axis to the underside of the skull.
It is also a distinct left-dome-like scar fibrotic changes in the region of the dens-axis, and substantial thickening and an outgrowth of bone-like character on the back of the dens-axis.
Our neck has seven neck vertebraes. Together they support our skull, moving the spine protects the spinal cord and the springer many nerves of neck vertebrae that are connected to the brain.
All seven cervical vertebrae are numbered, and C1 is the topmost, closest to the skull. C7 is the bottom.
C1 or Atlas, the top neck vertebra that carries our head. It is ring-shaped and rotates around the axis.
The top of the atlas forming articulation with the occipital bone.
C2 or Axis, is the second top neck vertebra. It has a "tooth" (dens-axis) protruding fortil forming articulation with atlas.
Together atlas and axis a pivot joint for neck and head.
The surgery is done by fuse C0-C4 with screws, bars and harvest bone. This will limit the movement in the neck by 80%, so I will not be able to do yes and no movment after the surgery is done.
By having a fusion the pain will be significant less because the movment is limited and this stops pressure on the upper cervical spinalcord and the brainsteam.
