Chronic, systemic inflammatory disorder that primarily affects joints.

It may result in deformed and painful joints, which can lead to loss of function. The disease may also have signs and symptoms in organs other than joints.

More than 85% of patients with moderate or severe rheumatoid arthritis (RA) have radiographic evidence of C-spine involvement ¹⁾.

The grading system of Ranawat et al. ²⁾. is used in RA as well as some other etiologies of myelopathy.

The cause of RA is not completely understood.
