Bursitis (bur-SY-tis) is a painful condition that affects the small, fluid-filled sacs — called bursae (bur-SEE) — that cushion the bones, tendons and muscles near your joints. Bursitis occurs when bursae become inflamed. The most common locations for bursitis are in the shoulder, elbow and hip.
Bursitis is inflammation of a bursa. A bursa is a closed, fluid-filled sac that works as a cushion and gliding surface to reduce friction between tissues of the body. The major bursae (this is the plural of bursa) are located next to the tendons near the large joints, such as in the shoulders, elbows, hips, and knees.
What causes bursitis? Repetitive motions, such as a pitcher throwing a baseball over and over, commonly cause bursitis. Also, spending time in positions that put pressure on part of your body, such as kneeling, can cause a flare-up. Occasionally, a sudden injury or infection can cause bursitis.
Bursitis generally gets better on its own. Conservative measures, such as rest, ice and taking a pain reliever, can relieve discomfort. If conservative measures don't work, you might require: Medication.
Bursae, are small, jelly-like sacs that are located throughout the body, including around the shoulder, elbow, hip, knee, and heel. They contain a small amount of fluid, and are positioned between bones and soft tissues, acting as cushions to help reduce friction. Bursitis is inflammation of the bursa.
A bursal sac is made up of an outer membrane and inner fluid. The synovial membrane forms a bursa's enclosed sac. A healthy synovial membrane is very thin, often just a few cells thick. The membrane produces the synovial fluid that is contained it the sac.
Definition of bursa : a bodily pouch or sac: such as. a : a small serous sac between a tendon and a bone.
Common types of bursitis include prepatellar, olecranon, trochanteric, and retrocalcaneal. Most patients respond to nonsurgical management, including ice, activity modification, and nonsteroidal anti-inflammatory drugs.
Ultrasound and MRI specifically are used to confirm the diagnosis when the bursae are too deep for regular inspection. In cases where the swelling is particularly painful, red, or warm, your doctor may withdraw fluid from the bursa to check for infection.
The key difference between arthritis and bursitis is the anatomical structures that they affect. Arthritis is a chronic condition that irreparably damages bone, cartilage, and joints, whereas bursitis is a temporary condition that involves the painful swelling of bursae for a time. Pain is worst in the morning.
Bursitis of the shoulder (impingement syndrome) occurs when there is swelling and redness between the top of the arm bone and the tip of the shoulder. The most common causes of bursitis are injury or overuse. Infection may also cause it. To relieve bursitis of the shoulder, avoid doing the things that cause pain.
Bursitis is the painful swelling of bursae. Bursae are fluid-filled sacs that cushion your tendons, ligaments, and muscles. When they work normally, bursae help the tendons, ligaments, and muscles glide smoothly over bone. But when the bursae are swollen, the area around them becomes very tender and painful.
