In response to irritation or injury the bursa may become inflamed, causing pain, restricting motion, and producing more fluid than can be absorbed readily. An attack of bursitis usually causes great pain and tenderness in the affected area. Common areas of involvement include the shoulder and big toe (see bunionbunion,

Bursitis

inflammation of the mucous sacs, predominantly in the region of the joints. In man the causes of bursitis are traumas, frequent and repeated mechanical irritations, infections, and diathesis. In acute bursitis swelling, edema, and pain are noted at the site of the mucous sac; within the sac there is a serous or purulent exudate, and more rarely (in traumatic bursitis), blood. Chronic bursites are frequently associated with occupation (bursitis of the knee joint in floor polishers, of the elbow in miners, and so on); they are manifested by thickening of the walls of the sac, a large accumulation of fluid in it, and so forth. Treatment includes resting the joint, thermal procedures, ultra-high frequency current, and, in a number of cases, surgery. While doing work associated with constant traumatization of the joint, it is necessary to wear a protective binding.

Bursitis of animals. The animals predominantly affected by bursitis are horses and cattle. Causes of the disease include prolonged mechanical irritation (lying on a hard floor, a poorly adjusted harness, and so on), traumatic injuries, certain infections and infestations (brucellosis, onchocerciasis, and other specific bursites). A painful swelling forms in the region of inflammation; in purulent bursitis the body temperature is elevated; in bursitis of the extremities there is limping. In the first days of the disease (nonpurulent bursitis) treatment consists of icepacks and tight bindings, then hot compresses and resolvent ointments. Prophylaxis is directed toward observance of hygienic rules of housing and maintaining animals.

Bursitis

Definition

Bursitis is the painful inflammation of the bursa, a padlike sac found in areas subject to friction. Bursae cushion the movement between the bones, tendons and muscles near the joints. Bursitis is most often caused by repetitive movement and is known by several common names including weaver's bottom, clergyman's knee, and miner's elbow, depending on the affected individual's occupation and area of injury.

Description

There are over 150 bursae in the human body. Usually bursae are present from birth, but they may form in response to repeated pressure. Each sac contains a small amount of synovial fluid, a clear liquid that acts as a lubricant. Inflammation causes pain on movement. The most common site for bursitis to occur is the shoulder (subdeltoid), but it also is seen in the elbows (olecranon), hips (trochanteric), knees, heels (Achilles), and toes. The affected area may be referred to as "frozen," because movement is so limited. In the knee there are four bursae, and all can become inflamed with overuse.

Causes and symptoms

The most common cause of bursitis is repeated physical activity, but it can flare up for no known reason. It can also be caused by trauma, rheumatoid arthritis, gout, and acute or chronic infection.Pain and tenderness are common symptoms. If the affected joint is close to the skin, as with the shoulder, knee, elbow, or Achilles tendon, swelling and redness are seen and the area may feel warm to the touch. The bursae around the hip joint are deeper, and swelling is not obvious. Movement may be limited and is painful. In the shoulder, it may be difficult to raise the arm out from the side of the body. Putting on a jacket or combing the hair becomes a troublesome activity.In acute bursitis symptoms appear suddenly; with chronic bursitis, pain, tenderness, and limited movement reappear after exercise or strain.

Diagnosis

When a patient has pain in a joint, a careful physical examination is needed to determine what type of movement is affected and if there is any swelling present. Bursitis will not show up on x-rays, although sometimes there are also calcium deposits in the joint that can be seen. Inserting a thin needle into the affected bursa and removing (aspirating) some of the synovial fluid for examination can confirm the diagnosis. In most cases, the fluid will not be clear. It can be tested for the presence of microorganisms, which would indicate an infection, and crystals, which could indicate gout. In instances where the diagnosis is difficult, a local anesthetic (a drug that numbs the area) is injected into the painful spot. If the discomfort stops temporarily, then bursitis is probably the correct diagnosis.

Treatment

Conservative treatment of bursitis is usually effective. The application of heat, rest, and immobilization of the affected joint area is the first step. A sling can be used for a shoulder injury; a cane is helpful for hip problems. The patient can take nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin, ibuprofin, and naproxen. They can be obtained without a prescription and relieve the pain and inflammation. Once the pain decreases, exercises of the affected area can begin. If the nearby muscles have become weak because of the disease or prolonged immobility, then exercises to build strength and improve movement are best. A doctor or physical therapist can prescribe an effective regimen.If the bursitis is related to an inflammatory condition like arthritis or gout, then management of that disease is needed to control the bursitis.When bursitis does not respond to conservative treatment, an injection into the joint of a long-acting corticosteroid preparation, like prednisone, can bring immediate and lasting relief. A corticosteroid is a hormonal substance that is the most effective drug for reducing inflammation. The drug is mixed with a local anesthetic and works on the joint within five minutes. Usually one injection is all that is needed.Surgery to remove the damaged bursa may be performed in extreme cases.If the bursitis is caused by an infection, then additional treatment is needed. Septic bursitis is caused by the presence of a pus-forming organism, usually staphylococcus aureus. This is confirmed by examining a sample of the fluid in the bursa and requires treatment with antibiotics taken by mouth, injected into a muscle or into a vein (intravenously). The bursa will also need to be drained by needle two or three times over the first week of treatment. When a patient has such a serious infection, there may be underlying causes. There could be undiscovered diabetes, or an inefficient immune system caused by human immunodeficiency virus infection (HIV).

Key terms

Arthritis — Inflammation of a joint that may lead to changes in the joint's structure. It causes pain and swelling. Rheumatoid arthritis is a chronic disease that leads to crippling deformities.Diabetes mellitus — A metabolic disease caused by a deficiency of insulin, which is essential to process carbohydrates in the body.Gout — A hereditary metabolic disease that is a form of arthritis and causes inflammation of the joints. It is more common in men.Inflammation — The reaction of tissue to injury.Kinesiology — The science or study of movement.

Alternative treatment

Alternative treatments take into consideration the role of diet in causing bursitis. The faulty use of calcium by the body, magnesium deficiency, and food allergies may have a role. Diet changes and vitamin supplements may be helpful. The use of herbs, homeopathy, aromatherapy, and hydrotherapy can help relieve symptoms. Ginger is useful in reducing inflammation. Acupuncture has been proven effective in treating hip and shoulder pain caused by bursitis and other conditions. Other therapies that deal effectively with musculoskeletal problems (relating to the muscles and skeleton), may also be helpful, such as body work, magnetic field therapy, naturopathic medicine, chiropractic, and applied kinesiology.

Prognosis

Bursitis usually responds well to treatment, but it may develop into a chronic condition if the underlying cause is not corrected.

Prevention

Aggravating factors should be eliminated to prevent bursitis. Overexercising or the repetition of a movement that triggers the condition should be avoided. Doing exercises to strengthen the muscles around the joint will also help. When doing repetitive tasks, frequent breaks should be taken and the activity should be alternated with others using different parts of the body. To cushion the joints, it is a good idea to use cushioned chairs when sitting and foam kneeling pads for the knees. Leaning on the elbows, kneeling or sitting on a hard surface for a long period of time should be avoided. Not wearing high heels can help prevent bursitis in the heel, as can changing to new running shoes as soon as the old ones are worn out.

bursitis

[ber-si´tis] inflammation of a bursa; types are usually named for the bursa involved. The subdeltoid bursa in the shoulder is most commonly affected, but inflammation may develop in almost any bursa in the body. Excessive use of the joint is often the cause. Acute bursitis comes on suddenly; severe pain and limitation of motion of the affected joint are the principal symptoms. Resting the joint, moist heat, and the use of analgesics or nonsteroidal antiinflammatory drugs frequently are sufficient treatment. Chronic bursitis may follow the acute attacks. There is continued pain and limitation of motion around the joint. X-ray examination will usually reveal the deposit of calcium salts. If rest, heat, and medications do not relieve the condition, surgery may be required to remove the calcium deposits or free the area of chronic inflammation.

bur·si·tis

(bŭr-sī'tis) Inflammation of a bursa that is most often caused by overuse or repeated stress to a joint. Symptoms include swelling, pain, and decreased range of motion.
Synonym(s): bursal synovitis. [Med. L. bursa, purse + itis]

bursitis

(bur-sit'is) [ bursa + -itis] Inflammation of a bursa, esp. between bony prominences and muscle or tendon, as in the shoulder and knee. It is typically caused by repeated stresses placed on a joint during work or play, but sometimes results from sudden trauma, from inflammatory joint disease, or bacteria. Common forms include rotator cuff, miner's or tennis elbow, and prepatellar bursitis. Fluid accumulation in the bursa results in irritation, inflammation, sudden or gradual pain, and symptoms such as impaired joint movement.

Treatment

Therapy includes rest and immobilization of the affected part during the acute stage. Active mobilization as soon as acute symptoms subside will help to reduce the likelihood of adhesions. Nonsteroidal anti-inflammatory drugs, analgesics, local application of cold then heat, and diathermy are helpful. Fluid removal (aspiration of the bursa) and injection of local anesthetics and cortisone into bursae may be required to reduce inflammation and relieve pain. In chronic bursitis, surgery may be necessary.

Patient care

Rest is prescribed, and movement of the affected part is restricted during the acute phase if pain and limited range of joint motion are present. If pain and loss of function are severe and do not improve with rest, the patient is referred for medical evaluation; physical therapy may also be needed to maintain joint mobility and prevent neighboring muscle atrophy.

anserine bursitis

Inflammation of the sartorius bursa located over the medial side of the tibia just below the knee.

PREPATELLAR BURSITIS

prepatellar bursitis

An inflammation of the bursa anterior to the patella, with accumulation of fluid. It may be seen in those who have to kneel frequently or continually while working. Synonym: carpetlayer's knee; housemaid's knee; roofer's knee See: illustration

septic bursitis

Bursitis caused by bacterial invasion of the joint.

bursitis

Inflammation of a BURSA. Bursitis is commonly due to excess local pressure or undue friction, but it may also result from rheumatic disease or infection. Common examples are HOUSEMAID'S KNEE, TENNIS ELBOW and BUNION.
