Arthropathies
An arthropathy is a disease of a joint. Types Arthritis is a form of arthropathy that involves inflammation of one or more joints, while the term arthropathy may be used regardless of whether there is inflammation or not. Joint diseases can be classified as follows: * Arthritis :*Infectious arthritis ::*Septic arthritis (infectious) ::* Tuberculosis arthritis ::* Reactive arthritis (indirectly) :*Noninfectious arthritis ::*Seronegative spondyloarthropathy: :::*Psoriatic arthritis :::*Ankylosing spondylitis ::*Rheumatoid arthritis:'' :::* Felty's syndrome ::*Juvenile idiopathic arthritis ::* Adult-onset Still's disease ::*Crystal arthropathy :::*Gout :::*Chondrocalcinosis ::*Osteoarthritis * Hemarthrosis (joint bleeding) * Synovitis is the medical term for inflammation of the synovial membrane. * Joint dislocation With ''arthropathy'' in the name * ''Reactive arthropathy'' (M02-M03) is caused by an infection, but not a direct infection of the synovial space.

Joint
A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole.Saladin, Ken. Anatomy & Physiology. 7th ed. McGraw-Hill Connect. Webp.274/ref> They are constructed to allow for different degrees and types of movement. Some joints, such as the knee, elbow, and shoulder, are self-lubricating, almost frictionless, and are able to withstand compression and maintain heavy loads while still executing smooth and precise movements. Other joints such as sutures between the bones of the skull permit very little movement (only during birth) in order to protect the brain and the sense organs. The connection between a tooth and the jawbone is also called a joint, and is described as a fibrous joint known as a gomphosis. Joints are classified both structurally and functionally. Classification The number of joints depends on if sesamoids are included, age of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ankylosing Spondylitis
Ankylosing spondylitis (AS) is a type of arthritis characterized by long-term inflammation of the joints of the spine typically where the spine joins the pelvis. Occasionally areas affected may include other joints such as the shoulders or hips, eye and bowel problems may occur as well as back pain. Joint mobility in the affected areas generally worsens over time. Although the cause of ankylosing spondylitis is unknown, it is believed to involve a combination of genetic and environmental factors. More than 85% of those affected in the UK have a specific human leukocyte antigen known as the HLA-B27 antigen. The underlying mechanism is believed to be autoimmune or autoinflammatory. Diagnosis is typically based on the symptoms with support from medical imaging and blood tests. AS is a type of seronegative spondyloarthropathy, meaning that tests show no presence of rheumatoid factor (RF) antibodies. There is no known cure for AS. Treatments may include medication, exercise, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemarthrosis
Hemarthrosis is a bleeding into joint spaces. It is a common feature of hemophilia. Causes It usually follows injury but occurs mainly in patients with a predisposition to hemorrhage such as those being treated with warfarin (or other anticoagulants) and patients with hemophilia. It can be associated with knee joint arthroplasty. It has also been reported as a part of hemorrhagic syndrome in the Crimean-Congo Hemorrhagic Fever, suggesting a viral cause to the bleeding in a joint space. Diagnosis Hemarthrosis is diagnosed through the methods listed below: A physical examination is the first step, the joints of the patient are moved and bent to study the functioning. Synovial Fluid analysis is another method to diagnose Hemarthrosis. It involves a small needle being inserted into the joint to draw the fluid. Reddish-colored hue of the sample is an indication of the blood being present. Imaging tests are normally done. The tests also include MRI, Ultrasound and X-ray test, which ...

Seronegative Spondyloarthropathy
Spondyloarthropathy or spondyloarthrosis refers to any joint disease of the vertebral column. As such, it is a class or category of diseases rather than a single, specific entity. It differs from spondylopathy, which is a disease of the vertebra itself, but many conditions involve both spondylopathy and spondyloarthropathy. Spondyloarthropathy with inflammation is called axial spondyloarthritis. In the broadest sense, the term spondyloarthropathy includes joint involvement of vertebral column from any type of joint disease, including rheumatoid arthritis and osteoarthritis, but the term is often used for a specific group of disorders with certain common features, which are often specifically termed seronegative spondylarthropathies. They have an increased incidence of HLA-B27, as well as negative rheumatoid factor and ANA. Enthesopathy is also sometimes present in association with seronegative . Non-vertebral signs and symptoms of degenerative or other not directly infected infl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bone Erosion
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. Surprisingly, bone erosion is not common in osteoarthritis Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone which affects 1 in 7 adults in the United States. It is believed to be the fourth leading cause of disability in the w ..., although there is a subtype of osteoarthritis (erosive osteoarthritis) that may result in bone erosion.

Synovitis
Synovitis is the medical term for inflammation of the synovial membrane. This membrane lines joints that possess cavities, known as synovial joints. The condition is usually painful, particularly when the joint is moved. The joint usually swells due to synovial fluid collection. Synovitis may occur in association with arthritis as well as lupus, gout, and other conditions. Synovitis is more commonly found in rheumatoid arthritis than in other forms of arthritis, and can thus serve as a distinguishing factor, although it is also present in many joints affected with osteoarthritis. In rheumatoid arthritis, the fibroblast-like synoviocytes, highly specialized mesenchymal cells found in the synovial membrane, play an active and prominent role in the synovitis. Long term occurrence of synovitis can result in degeneration of the joint. Signs and symptoms Synovitis causes joint tenderness or pain, swelling and hard lumps, called nodules. When associated with rheumatoid arthritis, swe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chondrocalcinosis
Chondrocalcinosis or cartilage calcification is calcification (accumulation of calcium salts) in hyaline cartilage and/or fibrocartilage.Rothschild, Bruce M It can be seen on radiography. Causes Buildup of calcium phosphate in the ankle joints has been found in about 50% of the general population, and may be associated with osteoarthritis. Another common cause of chondrocalcinosis is calcium pyrophosphate dihydrate crystal deposition disease (CPPD). CPPD is estimated to affect 4% to 7% of the adult populations of Europe and the United States. This topic last updated: Jul 24, 2018. Previous studies have overestimated the prevalence by simply estimating the prevalence of chondrocalcinosis regardless of cause. A magnesium deficiency may cause chondrocalcinosis, and there is anecdotal evidence that magnesium supplementation may reduce or alleviate symptoms. In some cases, arthritis from injury can cause chondrocalcinosis. Other causes of chondrocalcinosis include: *Hypercalcaemia, e ...

Osteoarthritis
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone which affects 1 in 7 adults in the United States. It is believed to be the fourth leading cause of disability in the world. The most common symptoms are joint pain and stiffness. Usually the symptoms progress slowly over years. Initially they may occur only after exercise but can become constant over time. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs. The most commonly involved joints are the two near the ends of the fingers and the joint at the base of the thumbs; the knee and hip joints; and the joints of the neck and lower back. Joints on one side of the body are often more affected than those on the other. The symptoms can interfere with work and normal daily activities. Unlike some other types of arthritis, only the joints, not internal organs, are af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Dislocation
A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet.Dislocations. Lucile Packard Children’s Hospital at Stanford. Retrieved 3 March 2013 A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves. Dislocations can occur in any major joint (shoulder, knees, etc.) or minor joint (toes, fingers, etc.). The most common joint dislocation is a shoulder dislocation. Treatment for joint dislocation is usually by closed reduction, that is, skilled manipulation to return the bones to their normal position. Reduction should only be performed by trained medical professionals, because it can cause injury to soft tissue and/or the nerves and vascular structures around the dislocation. Symptoms and signs The following symptoms are common with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synovial Membrane
The synovial membrane (also known as the synovial stratum, synovium or stratum synoviale) is a specialized connective tissue that lines the inner surface of capsules of synovial joints and tendon sheath. It makes direct contact with the fibrous membrane on the outside surface and with the synovial fluid lubricant on the inside surface. In contact with the synovial fluid at the tissue surface are many rounded macrophage-like synovial cells (type A) and also type B cells, which are also known as fibroblast-like synoviocytes (FLS). Type A cells maintain the synovial fluid by removing wear-and-tear debris. As for the FLS, they produce hyaluronan, as well as other extracellular components in the synovial fluid. Structure The synovial membrane is variable but often has two layers: * The outer layer, or subintima, can be of almost any type of connective tissue – fibrous (dense collagenous type), adipose (fatty; e.g. in intra-articular fat pads) or areolar (loose collagenous typ ...

Crystal Arthropathy
Crystal arthropathy is a class of joint disorder (called ''arthropathy'') that is characterized by accumulation of tiny crystals in one or more joints. Polarizing microscopy and application of other crystallographic techniques have improved identification of different microcrystals including monosodium urate, calcium pyrophosphate dihydrate, calcium hydroxyapatite, and calcium oxalate. Types Causes *Deposition of crystals in joints * Calcium pyrophosphate dihydrate crystal formation: **Increased production of inorganic pyrophosphate **Decreased levels of pyrophosphatase in cartilage **Decreased levels of cartilage glycosaminoglycans **Hyperparathyroidism **Hemochromatosis **Hypophosphatasia **Hypomagnesemia *Hydroxyapatite deposition: ** Tissue damage **Hyperparathyroidism **Hypercalcemia **Hyperphosphatemia *Calcium oxalate deposition: **Enhanced production of oxalic acid due to enzyme defect **Poor excretion of oxalic acid in kidney failure **Excessive ascorbic acid intake ...

Reactive Arthropathy
Reactive arthritis, also known as Reiter's syndrome, is a form of inflammatory arthritis that develops in response to an infection in another part of the body (cross-reactivity). Coming into contact with bacteria and developing an infection can trigger the disease. By the time the patient presents with symptoms, often the "trigger" infection has been cured or is in remission in chronic cases, thus making determination of the initial cause difficult. The arthritis often is coupled with other characteristic symptoms; this has been called Reiter's syndrome, Reiter's disease or Reiter's arthritis. The term "reactive arthritis" is increasingly used as a substitute for this designation because of Hans Reiter's war crimes with the Nazi Party. The manifestations of reactive arthritis include the following triad of symptoms: an inflammatory arthritis of large joints, inflammation of the eyes in the form of conjunctivitis or uveitis, and urethritis in men or cervicitis in women.
