CHARACTERIZATION AND FUNCTIONAL ASSESSMENT OF PATIENTS SUBJECTED TO OCCIPITOCERVICAL FUSION FOR RHEUMATOID ATLANTOAXIAL DISLOCATION

20 patients with rheumatoid arthritis and atlanto-axial dislocation subjected to occipito-cervical fusion were studied. The patients were evaluated by a rheumatologist before surgery and 6-12 months after the fusion procedure. Joint tenderness was assessed by Ritchie's Index while the functional capacity was evaluated using a health assessment questionnaire and according to the classification by Steinbrocker. Localization and character of the symptoms from the head-neck region were registered. The neck pain was measured on a visual analogue scale. Radiographs of hands and wrists were obtained before surgery and joint destruction was classified according to the Larsen Dale Index. Reduction of pain and neurological symptoms was observed in the majority. There was, however, little evidence of improved functional capacity.
