Charcot’s Joint: From 1 Different Sources

Named after a 19th-century French physician, this condition presents as a painless swelling and disorganisation of the joints resulting from damage to the pain ?bres that occurs in diabetic neuropathy (see DIABETES MELLITUS – Complications), LEPROSY, SYRINGOMYELIA and syphylitic infection of the spinal cord (see SYPHILIS).

Hip-joint

The joint formed by the head of the thigh bone and the deep, cup-shaped hollow on the side of the pelvis which receives it (acetabulum). The joint is of the ball-and-socket variety, is dislocated only by very great violence, and is correspondingly di?cult to reduce to its natural state after dislocation. It is enclosed by a capsule of ?brous tissue, strengthened by several bands, of which the principal is the ilio-femoral or Y-shaped ligament placed in front of the joint. A round ligament also unites the head of the thigh bone to the margin of the acetabulum.

Temporomandibular Joint Syndrome

Pain and other symptoms affecting the head, jaw, and face, thought to result when the temporomandibular joints and the muscles and ligaments attached to them do not work together correctly. Causes include spasm of the chewing muscles, an incorrect bite (see malocclusion), jaw, head, or neck injuries, or osteoarthritis. Common symptoms include headaches, tenderness of the jaw muscles, and aching facial pain. Treatment involves correction of any underlying abnormality, analgesic drugs, and, in some cases, injection of corticosteroid drugs into the joint.... temporomandibular joint syndrome

Knee-joint Replacement

A surgical operation to replace a diseased – usually osteoarthritic – KNEE with an arti?cial (metal or plastic) implant which covers the worn cartilage. As much of the original joint as possible is retained. The operations, like hip replacements, are usually done on older people (there is some restriction of movement) and about 90 per cent are successful.... knee-joint replacement

Sacroiliac Joint

One of a pair of joints between each side of the SACRUM and each ILIUM. Strong ligaments between the ilium and the sacrum stabilise the joint, permitting little movement. Childbirth or strenuous sporting activities may strain the joint, causing pain in the lower part of the back and buttocks. Such strains may take a long time to mend; PHYSIOTHERAPY is the treatment. The joint(s) may become in?amed (see SACROILEITIS).... sacroiliac joint

Joints

A joint is the articulation point between di?erent parts of the skeleton, whether bone or cartilage. Joints are divided into those which are ?xed or relatively ?xed (?brous and cartilaginous joints), and those which allow free movement (synovial joints). In the former, exempli?ed by the sutures between the bones of the skull, a layer of cartilage or ?brous tissue lies between the bones, binding them ?rmly together. Amphiarthrodial joints, exempli?ed by the joints between the vertebral bodies (see SPINAL COLUMN), have a thick disc of ?brocartilage between the bones. Although the individual joint is capable of very little movement, a series of these gives to the spinal column, as a whole, a ?exible character.

All movable joints involve four structures: the bones whose junction forms the joint; a layer of cartilage covering the ends of these, making them smooth; a ?brous sheath, the capsule, thickened at various points into bands or ligaments, which hold the bones together; and, ?nally, the synovial membrane, which lines the capsule and produces a synovial ?uid, lubricating the movements of the joint. In addition, the bones are kept in position at the joints by the various muscles passing over them and by atmospheric pressure. Where the ends of the bones do not quite correspond, a subsidiary disc of ?bro-cartilage may help to adapt the ends of the bones more perfectly to each other. Larger cavities may be ?lled by movable pads of fat under the synovial membrane, giving additional protection to the joint.

Varieties After this main division of joints into those which are ?xed and those movable, the movable joints may be further subdivided. In gliding joints, such as the wrist and ankle, the bones have ?at surfaces capable of only a limited amount of movement. In hinge joints, such as the elbow and knee, movement takes place around one axis. Ball-and-socket joints, exempli?ed by the shoulder and hip, allow free movement in any direction. Subsidiary varieties are named according to the shape of the bones which enter the joint.... joints

Dislocation, Joint

Complete displacement of the 2 bones in a joint so that they are no longer in contact, usually as a result of injury. (Displacement that leaves the bones in partial contact is called subluxation.) It is usually accompanied by tearing of the joint ligaments and damage to the membrane that encases the joint. Injury severe enough to cause dislocation often also causes bone to fracture. Dislocation restricts or prevents the movement of the joint; it is usually very painful. The joint looks misshapen and swells. In some cases, dislocation is followed by complications, for example, paralysis.A dislocated joint should only be manipulated by medical personnel. First- aid treatment consists of applying a splint or, in the case of a dislocated shoulder, a sling. Sometimes, an operation is necessary to reset the bones.... dislocation, joint

Effusion, Joint

The accumulation of fluid in a joint space, causing swelling, limitation of movement, and usually pain and tenderness. A joint is enclosed by a capsule lined with a membrane called the synovium. The synovium normally secretes small amounts of fluid to lubricate the joint, but if it is damaged or inflamed (for example, by arthritis) it produces excessive fluid.

Pain and inflammation may be relieved by analgesic drugs, nonsteroidal anti-inflammatory drugs, and injections of corticosteroid drugs.

Swelling usually reduces with rest, firm bandaging, icepacks, and keeping the affected joint raised.

In some cases, the fluid is drawn out with a needle and syringe.... effusion, joint

Facet Joint

A type of joint found in the spine, formed by the bony knob (called a process) of one vertebra fitting into a hollow in the vertebra above. Facet joints allow a degree of movement between individual vertebrae, which gives the spine its flexibility.... facet joint

Finger-joint Replacement

A surgical procedure in which one or more artificial joints made of metal, plastic, or silicone rubber are used to replace finger joints destroyed by disease, usually rheumatoid arthritis or osteoarthritis.

The procedure is usually successful in relieving arthritic pain and enabling the patient to use his or her hands again, but it rarely restores normal movement.... finger-joint replacement

Metatarsophalangeal Joint

The joint between each metatarsal bone and its adjoining toe bone (see phalanges). The metatarsophalangeal joint at the base of the big toe is commonly affected by gout and by hallux rigidus.... metatarsophalangeal joint

Joints, Diseases Of

‘Rheumatism’ is the colloquial term for nonspeci?c musculoskeletal symptoms arising in the joints, ligaments, tendons and muscles. ‘Arthritis’ describes a pathological musculoskeletal disorder. Most common are sprains of ligaments, strains of tendons and muscles,

BURSITIS, TENDINITIS and non-speci?c back pain (see BACKACHE).

Osteoarthritis (OA) rarely starts before 40, but by the age of 80 affects 80 per cent of the population. There are structural and functional changes in the articular cartilage, as well as changes in the collagenous matrix of tendons and ligaments. OA is not purely ‘wear and tear’; various sub-groups have a genetic component. Early OA may be precipitated by localised alteration in anatomy, such as a fracture or infection of a joint. Reactive new bone growth typically occurs, causing sclerosis (hardening) beneath the joint, and osteophytes – outgrowths of bone – are characteristic at the margins of the joint. The most common sites are the ?rst metatarsal (great toe), spinal facet joints, the knee, the base of the thumb and the terminal ?nger joints (Heberden’s nodes).

OA has a slow but variable course, with periods of pain and low-grade in?ammation. Acute in?ammation, common in the knee, may result from release of pyrophosphate crystals, causing pseudo-gout.

Urate gout results from crystallisation of URIC ACID in joints, against a background of hyperuricaemia. This high concentration of uric acid in the blood may result from genetic and environmental factors, such as excess dietary purines, alcohol or diuretic drugs.

In?ammatory arthritis is less common than OA, but potentially much more serious. Several types exist, including: SPONDYLARTHRITIS This affects younger men, chie?y involving spinal and leg joints. This may lead to in?ammation and eventual ossi?cation of the enthesis – that is, where the ligaments and tendons are inserted into the bone around joints. This may be associated with disorders in other parts of the body: skin in?ammation (PSORIASIS), bowel and genito-urinary in?ammation, sometimes resulting in infection of the organs (such as dysentery). The syndromes most clearly delineated are ankylosing spondylitis (see SPINE AND SPINAL CORD, DISEASES AND INJURIES OF), psoriatic or colitic spondylitis, and REITER’S SYNDROME. The diagnosis is made clinically and radiologically; no association has been found with autoantibodies (see AUTOANTIBODY). A particularly clear gene locus, HLA B27, has been identi?ed in ankylosing spondylitis. Psoriasis can be associated with a characteristic peripheral arthritis.

Systemic autoimmune rheumatic diseases (see AUTOIMMUNE DISORDERS). RHEUMATOID ARTHRITIS (RA) – see also main entry. The most common of these diseases. Acute in?ammation causes lymphoid synovitis, leading to erosion of the cartilage, associated joints and soft tissues. Fibrosis follows, causing deformity. Autoantibodies are common, particularly Rheumatoid Factor. A common complication of RA is Sjögren’s syndrome, when in?ammation of the mucosal glands may result in a dry mouth and eyes. SYSTEMIC LUPUS ERYTHEMATOSUS (SLE) and various overlap syndromes occur, such as systemic sclerosis and dermatomyositis. Autoantibodies against nuclear proteins such as DNA lead to deposits of immune complexes and VASCULITIS in various tissues, such as kidney, brain, skin and lungs. This may lead to various symptoms, and sometimes even to organ failure.

Infective arthritis includes: SEPTIC ARTHRITIS An uncommon but potentially fatal disease if not diagnosed and treated early with approriate antibiotics. Common causes are TUBERCLE bacilli and staphylococci (see STAPHYLOCOCCUS). Particularly at risk are the elderly and the immunologically vulnerable, such as those under treatment for cancer, or on CORTICOSTEROIDS or IMMUNOSUPPRESSANT drugs. RHEUMATIC FEVER Now rare in western countries. Resulting from an immunological reaction to a streptococcal infection, it is characterised by migratory arthritis, rash and cardiac involvement.

Other infections which may be associated with arthritis include rubella (German measles), parvovirus and LYME DISEASE.

Treatment Septic arthritis is the only type that can be cured using antibiotics, while the principles of treatment for the others are similar: to reduce risk factors (such as hyperuricaemia); to suppress in?ammation; to improve function with physiotherapy; and, in the event of joint failure, to perform surgical arthroplasty. NON-STEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS) include aspirin, paracetamol and many recently developed ones, such as the proprionic acid derivatives IBUPROFEN and naproxen, along with other drugs that have similar properties such as PIROXICAM. They all carry a risk of toxicity, such as renal dysfunction, or gastrointestinal irritation with haemorrhage. Stronger suppression of in?ammation requires corticosteroids and CYTOTOXIC drugs such as azathioprine or cyclophosphamide. Recent research promises more speci?c and less toxic anti-in?ammatory drugs, such as the monoclonal antibodies like in?iximab. An important treatment for some osteoarthritic joints is surgical replacement of the joints.... joints, diseases of

However, exceeding the number of cups may lead to a number of affections, such as upset stomach, skin rash, diarrhea and nausea. If you’ve been taking one of these teas for a while and you’re experiencing some unusual reactions, ask for medical assistance immediately. Don’t take a Tea for Joints if you’re pregnant, breastfeeding, on blood thinners or anticoagulants. The same advice if you’re preparing for a surgery (some of the active constituents might interfere with your anesthetic). But if you have the green light from your doctor, choose a Tea for Joints that fits best your needs and enjoy its great health benefits!... tea for joints

Neuropathic Joint

A joint that has been damaged by inflammation and a series of injuries, which pass unnoticed due to loss of sensation in the joint resulting from neuropathy (nerve damage caused by disease). Neuropathic joints develop in a number of conditions, including diabetes mellitus and untreated syphilis.

When sensation to pain is lost, abnormal stress and strain on a joint do not stimulate the protective reflex spasm of the surrounding muscles; this failure of the protective reflex allows exaggerated movement that can damage the joint. Osteoarthritis, swelling, and deformity are features of a neuropathic joint.An orthopaedic brace or caliper splint may be necessary to restrict any abnormal movement of the joint.

Occasionally, an arthrodesis (a surgical operation to fuse a joint) is performed.
