What is erosion arthritis?

What is erosion arthritis?

Erosive osteoarthritis is a type of inflammatory osteoarthritis. It can develop in the hinge joints of the fingers and less frequently in the toes. Clinically, these are known as the interphalangeal joints. Research suggests that less than 3 percent of people develop erosive osteoarthritis.

What causes bone erosion in finger?

RA causes chronic inflammation, which leads to gradual bone erosion. Classic RA symptoms include swollen joints, joint stiffness, and joint pain. Some people also have fatigue and loss of appetite. RA often affects the smaller joints like your hands, feet, and fingers, so bone erosion can occur in these joints.

What are heberden and Bouchard nodes?

Bony bumps on the finger joint closest to the fingernail are called Heberden’s nodes. Bony bumps on the middle joint of the finger are known as Bouchard’s nodes. Bony bumps are also common at the base of the thumb. These bumps do not have a nickname, but the joint is called the CMC or carpometacarpal joint.

What disease causes bone erosion?

Erosive arthritis is joint inflammation (arthritis) with bone destruction, and such conditions include rheumatoid arthritis. Bone erosion is the loss of bone in a certain area, rather than a change in bone density, which is found in osteoporosis….

What is bone erosions in rheumatoid arthritis?

Articular bone erosion represents localized bone loss (osteolysis), initially involving cortical bone, and destruction of the natural barrier between the extraskeletal tissue and the intertrabecular spaces of the bone marrow cavity.

What causes bone erosion in rheumatoid arthritis?

Chronic inflammation of synovial membrane (synovium) in RA results in hyperplasia and formation of pannus, a thickened, hypertrophied synovial membrane that invades the adjacent cartilage and bone and causes cartilage degradation and bone erosions.

Does rheumatoid arthritis cause bone erosion?

Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well.

Does rheumatoid arthritis have Bouchard’s nodes?

Much less commonly, they may be seen in rheumatoid arthritis, where nodes are caused by antibody deposition to the synovium. Bouchard’s nodes are comparable in presentation to Heberden’s nodes, which are similar osteoarthritic growths on the distal interphalangeal joints, but are significantly less common.

What does erosion of bone mean?

Bone erosions are bony defects developing as a result of excessive local bone resorption and inadequate bone formation 1. They are commonly associated with synovitis and osteitis 1.

Can Rheumatoid arthritis cause bone lesions?

Histopathologic characterization of bone erosions from patients with rheumatoid arthritis (RA) and studies performed in animal models of inflammatory arthritis provide strong evidence that osteoclasts play an important role in focal marginal and subchondral bone loss in inflammatory arthritis.

Does osteoarthritis cause bone erosion?

Fact: Osteoarthritis does not cause bone erosion. Osteoarthritis does not cause bone loss or fractures. On the contrary, it is associated with increased bone density and abnormal growths (osteophytes) due to the deficiency in bone resorption.
