Eight patients with ankylosing spondylitis underwent 13 total hip replacements between 1979 and 1990. The mean observation time was 5.5 years. The results were assessed according to pain, walking ability, mobility and activity of daily life. The over-all results were rated good. All hips improved in mobility after THR and this improvement was maintained during the follow-up period. No radiological signs of loosening were found. About 30% showed some evidence of ectopic ossification, but restriction of hip movements and coxalgia were not noted.
