[Inflammatory spine disease as a cause of back pain].

PURPOSE

The aim of this review is to evaluate the role of inflammatory spine disease in patients with chronic back pain. The contribution of imaging modalities for the diagnostic evaluation of back pain is discussed.

MATERIAL AND METHODS

A systematic literature search based on the classification of seronegative spondyloarthropathies and rheumatoid arthritis was performed. The results of this search and the experiences in a large collective of rheumatological patients are analyzed.

RESULTS

The prevalence of rheumatoid arthritis (1-2%) is comparable to that of spondyloarthropathies (1.9%). The etiology of these entities is not fully elucidated. Magnetic resonance imaging is increasingly used for early detection and surveillance of therapy with TNF-alpha antagonists.

DISCUSSION

Bone marrow edema, which is only detectable with MRI, represents an early sign of inflammation. Therapy with TNF-alpha antagonists is based on clinical and laboratory criteria, and signs of inflammation in MRI. MRI is useful for assessment of the effectiveness of anti-inflammatory therapy.
