2The Link between Pannus and Rheumatoid Arthritis
In people with rheumatoid arthritis, the body attacks healthy joints and surrounding tissues. Among the affected parts is the synovium, which works to lubricate the joints. Under the affects from white blood cells, blood vessels in the synovium grow quickly. This increases blood flow to the area and causes the synovium to become thicker over time. This abnormal growth of tissues in a restricted space between the bones and joints is known as pannus. Over time, pannus would spread and cover the cartilage and bones. In early stages of rheumatoid arthritis, small joints can be affected, such as the feet, hands, or wrists. It may also develop in the abdomen, heart, knees, shoulders, and eyes. [3]
