Summary
Objective. To assess retrospectively, the outcome of cervical spine surgery in patients with ankylosing spondylitis (AS).
Methods. A cross-sectional study of 3464 patients with identified AS, 19 patients of whom had cervical spine surgery. A self-administered questionnaire (including the use of 10 cm visual analogue scales, 0=none, 10=worst) assessing the complications of the surgery, patients' neck symptoms and post-surgery functional ability was sent to the 19 patients. Available casenotes and radiographs were reviewed. Results. The mean duration of follow-up was 10 years. One patient had two separate cervical spine operations. The types of surgery performed included cervical fusion (n=7), osteotomy (n=7) and laminectomy (n=6). Six patients had minor complications as a result of surgery. The majority of patients (93%) felt that their surgery had been successful. Most patients (81%) had a reduction in neck pain (mean pain score=3.1, SD 2.8) but increased neck stiffness (mean stiffness score=8.0, SD 2.9). Postoperative radiographs of 7 patients showed complete ankylosis of the cervical spine. Generally, few patients reported difficulty with reading/watching television (6%), sleep (19%) or driving (36%). A third of the patients were still in full time employment.
Conclusions. About 1 in 200 patients with AS undergo cervical spine surgery. The surgery is often successful and complications are usually minor. Neck pain is often better after surgery and any remaining neck symptoms do not significantly affect the patient's sleep or functional activities. In this retrospective study, the long term outcome of cervical spine surgery in patients with AS appears to be good.
