What is Juxta-articular erosion?
The term ‘bone erosion’ describes loss of mineralized tissue at juxta-articular sites, which is commonly associated with a break in the cortical lining. Figure 1. Hand radiograph of a patient with rheumatoid arthritis.
What are erosions in rheumatoid arthritis?
This progressive disease not only causes joint inflammation, but can lead to damage and deformity of joints. The damage is a result of erosion of the bones. Bone erosion is a key feature of RA. The risk increases with disease severity and is characterized by the loss of bone in certain parts of the body.
What is Juxta-articular osteopenia?
Juxta-articular osteopenia is another early sign, particularly during the acute inflammatory stage. Osteopenia subsequently becomes more generalized as the disease progresses.
What does Juxta-articular mean?
situated near a joint
Medical Definition of juxta-articular : situated near a joint juxta-articular inflammatory tissue.
What is Juxta-articular bone?
Definition. Juxta-articular bone cyst is an intraosseous nonneoplastic subchondral cystic lesion not related to joint pathology – especially osteoarthritis. The lesion contains mucoid fluid and is lined by fibrous tissue with myxoid change.
What are articular erosions?
An articular bone erosion is a radiological term that refers to a break in cortical bone with destruction of the natural barrier between the extraskeletal tissue and the bone marrow compartments, preferentially at the bare area of the joints, at the mineralized cartilage, or adjacent to the insertion sites of …
What is the difference between osteoarthritis and erosive osteoarthritis?
Compared with typical hand osteoarthritis (OA), this condition is more disabling and causes more severe joint pain and stiffness. Erosive OA is characterized by severe joint inflammation and bone breakdown, leading to characteristic X-ray findings, but it can also take longer to diagnose than typical OA.
What does joint erosion mean?
Bone erosion is the loss of bone from disease processes. 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 type of arthritis causes bone erosion?
Rheumatoid arthritis (RA) is an autoimmune condition that often causes bone erosion. Excess inflammation builds up in affected joints, leading to pain, stiffness, swelling, loss of motion, and difficulty with mobility.
What is Juxta-articular Adiposis Dolorosa?
Juxta-articular adiposis dolorosa may be defined as the localised accumulation of painful fat near joints, most commonly the knee. It exists as a separate entity that must be distinguished from other causes of knee pain.
What is Juxta-articular osteophytes?
Active osteophyte growth is a hallmark of osteoarthritis (OA)1. It is this active bony growth at the joint margins that separates osteophytes that are characteristic of the disease from those that appear to be associated with ageing2.
What causes bone erosion?
Bone erosion is typically caused by erosive arthritis conditions like PsA and rheumatoid arthritis (RA). Conditions like PsA and RA can progress, which means worsening inflammation, and the more inflammation there is, the more damage there will be to the bones.
What is articular damage?
Articular cartilage injuries are a common joint injury, especially among those who are physically active. This type of injury most frequently occurs in the knee, but it may also involve the hip, elbow, shoulder, and ankle.
What is cartilage erosion?
Cartilage damage is a relatively common type of injury. It often involves the knees, although joints such as the hips, ankles and elbows can also be affected. Cartilage is a tough, flexible tissue found throughout the body.
What does Juxta-Articular mean?
What causes juxta-articular erosions in gout?
Juxta-articular erosions become visible in chronic gout. Calcium pyrophosphate dihydrate deposition disease (CPPD) is frequently asymptomatic but may cause an acute arthritis which manifests clinically as pseudogout. CPPD does not cause erosions as seen in rheumatoid or gout.
How common are juxta-articular erosions and soft tissue calcifications in chronic renal failure?
Juxta-articular erosions and calcifications in patients with chronic renal failure The frequency of subperiosteal erosions and soft tissue calcifications was found to be about 36 and 33 per cent, respectively, in a series of 241 patients with chronic renal failure.
What is periarticular erosion in rheumatoid arthritis (RA)?
Erosion of periarticular cortical bone, the typical feature observed on plain radiographs in patients with rheumatoid arthritis, results from excessive local bone resorption and inadequate bone formation.
What are the main triggers of articular bone erosion?
The main triggers of articular bone erosion are synovitis, including the production of proinflammatory cytokines and receptor activator of nuclear factor κB ligand (RANKL), as well as antibodies directed against citrullinated proteins.
