Spinal Fractures Complicating Ankylosing Spondylitis

Twenty‐two spinal fractures in 20 patients with chronic ankylosing spondylitis are reported. Nineteen fractures occurred in the cervical region. Fourteen of the fractures were caused by minor falls, 3 by falls down steps, 4 by motor vehicle accidents, and 1 by cardiopulmonary resuscitation. Long‐term followup (mean 3.2 years) of 9 fractures diagnosed early and managed conservatively showed bony union of all fractures. No patient deteriorated neurologically and 3 patients made major recovery. Long‐term followup is also reported on 6 patients in whom the diagnosis was delayed. The difficulties in diagnosis and management are discussed.
