Cervical Spine Pathology Rheumatoid Atlanto-axial Subluxation rheumatology 3D animations. Atlanto-axial instability or atlanto-axial subluxation is abnormal movement and malalignment between the first and the second cervical vertebrae, the atlas and the axis. It is caused by erosion of the joints between the skull, C1 and C2 vertebra, and the transverse ligament holding C2's odontoid against C1. Atlanto-axial subluxation is the most common rheumatoid spine abnormality, found in rheumatology 3D animations. Most subluxations are anterior with the first cervical vertebra moving forward over the second cervical vertebra. Posterior, lateral and rotatory movements are also possible. Movement of adjacent vertebra can compress the spinal cord, called myelopathy, and the spinal nerves, called radiculopathy. Myelopathy at this level can cause paralysis of the arms and legs and difficulty breathing.
