What is a Juxta-articular erosion?
They are a classical feature of rheumatoid arthritis (RA). Central erosions occur into bone normally covered by the articular cartilage. They are less common and are typical of inflammatory (erosive) OA. Juxta-articular erosions occur further away from the joint and are characteristic of gout.
What is articular sclerosis?
Subchondral sclerosis, which is also called marginal sclerosis, is a thickening of the bone beneath the cartilage in joints. It can be associated with painful joint symptoms and bone spurs. Subchondral sclerosis is commonly seen in joints of the knee, hip, spine, and foot.
Is sclerosis and multiple sclerosis the same thing?
Multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) are different diseases with some similar features and symptoms. They both: Affect your muscles and your ability to move your body. Attack your brain and spinal cord.
What does Juxta articular mean?
Juxtaarticular: Near a joint. For example, a juxta-articular fracture is a break near a joint.
What does erosive arthropathy mean?
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 Juxta Articular?
What type of cartilage is articular cartilage?
hyaline cartilage
Articular cartilage is hyaline cartilage and is 2 to 4 mm thick. Unlike most tissues, articular cartilage does not have blood vessels, nerves, or lymphatics. It is composed of a dense extracellular matrix (ECM) with a sparse distribution of highly specialized cells called chondrocytes.
What is the difference between juxta articular sclerosis and sclerosis?
Near joint: Juxta articular refers to changes in the bone near a joint surface. Sclerosis often seen with early arthritic changes in a joint, or as the result of acute or repetitive trauma. Sclerosis results in bone hardening and often seen in conditions limiting blood flow to that area of bone.
What is the medical definition of juxta-articular?

What are juxta-articular erosions?
Juxta-articular erosions occur further away from the joint and are characteristic of gout. Rheumatoid erosions characteristically have no associated bone proliferation when untreated (Fig. 51-4A), whereas sero-negative erosions typically show proliferative bone formation in or around the erosion (Fig. 51-4B), a useful distinguishing feature.
What is periarticular osteopenia?
Osteopenia. Periarticular osteopenia is a well-recognised feature of some arthritides but is difficult to reliably identify. It may be more obvious in cases of mono- or pauci-articular joint involvement, where other joints are visible for comparison. An overexposed radiograph can mimic periarticular osteopenia, as can generalised osteoporosis.
