Inflammatory joint disorders comprise a broad group of disorders, which are characterised by inflammatory-destructive processes. They cause damage to the structure and function of articular and periarticular tissues. The entire skeleton and extraarticular organs/tissue could also be involved. Typical examples are rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis, Crohn’s disease and psoriatic arthritis.
