Bursitis is the inflammation of one or more bursae (synovial sacs) of synovial fluid in the body. They are lined with a synovial membrane that secretes a lubricating synovial fluid. [1] There are more than 150 bursae in the human body. [1] The bursae rest at the points where internal functionaries, such as muscles and tendons, slide across bone.
Subacromial bursitis. Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
Calcific bursitis refers to calcium deposits within the bursae. This most occurs in the shoulder area. The most common bursa for calcific bursitis to occur is the subacromial bursa. A bursa is a small, fluid-filled sac that reduces friction, and facilitates movements between its adjacent tissues (i.e., between tendon and bone, two muscles or ...
De Quervain syndrome occurs when two tendons that control movement of the thumb become constricted by their tendon sheath in the wrist. [3][5][6] This results in pain and tenderness on the thumb side of the wrist. [3] Radial abduction of the thumb is painful. [6] On some occasions, there is uneven movement or triggering of the thumb with radial ...
Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. [2] The pain is typically worse with movement. [2] It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis).
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. [ 1 ] Other common names include repetitive stress injury, repetitive stress disorders, cumulative trauma disorders (CTDs), and overuse syndrome.
Brachioradial pruritus (sometimes abbreviated BRP) is an intense itching sensation of the arm usually between the wrist and elbow of either or both arms. [1]: 36 The itch can be so intense that affected individuals will scratch their own skin to a bleeding condition. The condition is becoming increasingly common, presenting in patients who are ...
