Estimates for the prevalence of ankylosing spondylitis in patients with low back pain vary depending on the population studied and the criteria used to define this condition. The approximate prevalence of 0.3% is based on estimates from patients in the primary care setting with low back pain and unequivocal radiologic changes (1). The prevalence may be as high as 5% when using wider diagnostic criteria for axial spondyloarthritis (2), but the clinical manifestations and severity of symptoms vary substantially for this group of conditions.
