title: Spinal fractures complicating ankylosing spondylitis. A long-term followup study.
abstract: 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.
