Radiographic vertebral fractures occur frequently in patients with ankylosing spondylitis, according to Dr. Fiona Maas and her associates.
At baseline, 59 (20%) of the 292 patients included in a prospective cohort study had radiographic vertebral fractures. During a 2-year follow-up period, 15 patients developed new fractures and 7 patients experienced an increase in severity of current fractures. A significant majority of fractures were defined as mild, and most were located in the mid-thoracic and thoracolumbar regions of the spine.
Fractures were more likely in patients who were older, had a higher body mass index, had smoked for long durations, had larger occiput-to-wall distances, had more spinal radiographic damage, and had lower hip bone mineral density (BMD). Patients who developed new fractures during the study period were older and had lower hip BMD. Incidence and prevalence of fractures was reduced in patients who were receiving nonsteroidal anti-inflammatory drugs (NSAIDs) at baseline.
“The influence of anti-inflammatory drugs (e.g. NSAIDs, TNF-alpha inhibitors), anti-osteoporotic treatment (e.g. calcium/vitamin D supplements, bisphosphonates), and lifestyle changes (e.g. smoking cessation, body weight control, physical exercise) on the development of vertebral fractures in AS should be further investigated in a large study population with long-term follow-up,” the investigators concluded.
