Operations for the unstable cervical spine in rheumatoid arthritis

Abstract

Sixteen patients with seropositive rheumatoid arthritis were operated on for subaxial subluxations. Four of the patients had slight, but progressive, tetraparesis, and 5 had severe or total tetraparesis; they were operated on 1–4 months after the first signs. Seven patients were treated for severe neck and shoulder pain. Nine patients had subluxation at the C3–4 level, the most common site, and 3 patients also had an atlantoaxial subluxation. Patients with cord compression were treated with posterior laminectomies and fusions that relieved the tetraparesis. Two patients died during the early postoperative period: 1 of a cardiac infarction and the other of pneumonia. During 4 (1.5–9) years' follow-up, 3 patients had new subluxations at other levels.
