Rheumatoid Arthritis Pictures

Rheumatoid arthritis is a chronic inflammatory disease that primarily affects the joints and surrounding tissues.

Rheumatoid arthritis is a systemic autoimmune disease which initially attacks the synovium, a connective tissue membrane that lines the cavity between joints and secretes a lubricating fluid

The affect of rheumatoid arthritis can progress to the degree that it is crippling. Deformities distinctive to late-stage rheumatoid arthritis such as ulnar deviation of the bones of the hands, or swan-neck deviation of the fingers occur because muscles and tendons on one side of the joint may overpower those on the other side, pulling the bones out of alignment.
