title: Cervical myelopathy in rheumatoid arthritis.
abstract: Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated.
