Page 23 Bursitis and its effects on YOU
A bursa is a fluid-filled sac that cushions an area of friction between tissues, such as tendon and bone. Bursa reduce friction between moving parts of the body, such as around the joints of the shoulder, elbow, hip, knee, and adjacent to the Achilles tendon in the heel.
The number varies, but most people have about 160 bursa throughout the body. Bursa are lined with special cells, called
synovial cells, which secrete a fluid rich in collagen and proteins. This synovial fluid acts as a lubricant when parts of the body move. Inflammation of a bursa is referred to as bursitis.
Bursitis causes The most common causes of bursitis are repetitive motions (for example, repeated throwing of a ball), trauma (extensive kneeling), infection, and pre-existing rheumatoid conditions.
Trauma causes inflammatory bursitis from repetitive injury or direct impact. - Chronic bursitis: The most common cause of chronic bursitis is minor trauma that may occur to the shoulder (sub deltoid) bursa from repetitive motion, for example, throwing a ball. A another example is pre patellar bursitis (in front of the knee) from prolonged or repetitive kneeling on a hard surface to scrub a floor or lay carpet. - Acute bursitis: A direct blow (let’s say you accidentally knock your knee into a table) can cause blood to leak into the bursa. This causes inflammation with pain as well as swelling.
Infections Bursa close to the surface of the skin are the most likely to get infected with bacteria, a condition that is called septic bursitis. The most common bacteria to cause septic bursitis are Staphylococcus aureus or Staphylococcus epidermis. People with diabetes, alcoholism, and certain kidney conditions, those with a suppressed immune systems and those with wounds to the skin over a bursa are at higher risk for septic bursitis. About 85% of septic bursitis occurs in men.
Rheumatoid conditions People with certain diseases such as gout can develop bursitis from crystal deposits. When these crystals form in a bursa, they cause inflammation leading to bursitis.
