Bursitis and tendinitis are conditions that are also known as soft tissue rheumatic syndromes. A syndrome is a group of signs and symptoms that occur together and indicate a particular problem. This type of syndrome produces pain, swelling, or inflammation in the tissues and structures around a joint, such as the tendons, ligaments, bursae, and muscles.
Bursae are small fluid-filled sacs that reduce friction between moving parts in your body's joints. Shoulder bursitis is inflammation or irritation of a bursa shown in blue in your shoulder. Elbow bursitis is inflammation or irritation of the bursa shown in blue in your elbow.
The wrist joint contains the ends of the radius, ulna and eight carpal bones. This joint was designed to help the hand be capable of moving with a wide range of motion and flexibility. The wrist joint is surrounded by two individual bursa.
De Quervain's tendinosis occurs when the tendons around the base of the thumb are irritated or constricted. The word "tendinosis" refers to a swelling of the tendons. Swelling of the tendons, and the tendon sheath, can cause pain and tenderness along the thumb side of the wrist.
Wrist bursitis is inflammation of a bursa, which is a small sack of fluid that helps lubricate the movement of tendons over bone. There are two bursas in the wrist, and repetitive trauma or friction can cause them to become inflamed. Treatment involves rest and reducing inflammation.
Tendons are cord-like structures located where a muscle narrows down to attach to a bone. The tendon is more fibrous and dense than the elastic, fleshy muscle. A tendon transmits the pull of the muscle to the bone to cause movement.
Swelling and inflammation near a joint may be a sign of bursitis, a condition that involves buildup of liquid and inflammation in a bursa sac that cushions a joint. Excessive friction, a trauma, or other condition can irritate the synovium and cause it to become inflamed. The inflamed synovium will thicken and produce excess synovial fluid, and can cause symptoms such as localized swelling, skin redness and warmth, tenderness and pain. Of the approximately bursae in the body, only a handful of them usually cause bursitis.
A joint is formed when two bones meet and articulate, which allows movement. Joints are lined with smooth cartilage that allows for the easy movement of one bone relative to another. Osteoarthritisor degenerative arthritis, is a process that occurs with aging and describes the deterioration of the joint cartilage.
