Cervical Spondyloarthropathy Diagnosis and Management
Diagnostic Approach
- The American College of Rheumatology recommends conventional radiography of the cervical spine as the first-line imaging modality to assess structural damage and detect syndesmophytes in patients with established ankylosing spondylitis, with a high predictive value for disease progression 1, 2
- Baseline radiographic changes, such as syndesmophytes, are highly predictive of radiographic progression, with all studies demonstrating this correlation 1, 2
- The European League Against Rheumatism suggests that MRI should be added when radiography alone is insufficient, as it detects both active inflammatory lesions and structural changes 1, 4
Disease Monitoring
- The American College of Rheumatology recommends MRI of the spine to assess and monitor disease activity, providing additional information beyond clinical examination and CRP 6, 7
- Conventional radiography of the cervical spine should be used for long-term monitoring of structural damage, particularly new bone formation, with a recommended interval of no more than every 2 years 6, 5
Management Strategy
- The American College of Rheumatology suggests that extensive MRI inflammatory activity in the spine predicts good clinical response to anti-TNF-alpha treatment, and MRI findings should aid in the decision to initiate therapy 1, 6
- The Assessment of SpondyloArthritis international Society recommends that all patients should trial conservative therapy before interventional procedures, including over-the-counter medications and physical therapy for pain present more than one month with intensity >4/10 10
Special Considerations
- The National Osteoporosis Foundation recommends osteoporosis assessment in patients with syndesmophytes in the cervical spine, with hip DXA and either spine DXA in lateral projection or quantitative CT of the spine 1, 2
- The American College of Rheumatology recommends conventional radiography as the initial imaging method when spinal fracture is suspected, followed by CT if radiography is negative, and MRI for additional information on soft tissue lesions 6, 9
