Subacromial bursitis 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. The subacromial bursa helps the motion of the supraspinatus tendon of the rotator cuff in activities such as overhead work. Musculoskeletal complaints are one of the most common reasons for primary care office visits, and rotator cuff disorders are the most common source of shoulder pain. Primary inflammation of
Collateral ligaments of metacarpophalangeal joints while the proper ligaments are shortened. As a result, the joint is stable during full flexion while the relaxed collateral ligaments allows lateral and rotation movements during extension. The tendons of interosseous and lumbricales add to the lateral stability of the joint. Collateral ligaments of metacarpophalangeal joints In human anatomy, the radial (RCL) and ulnar (UCL) collateral ligaments of the metacarpophalangeal joints (MCP) of the hand are the primary stabilisers of the MCP joints. They have two parts: the cord-like collateral ligaments proper located more dorsally and the accessory collateral ligaments located more volarly. They enable us to spread our
