shoulder

 [shōl´der]
the area around the glenohumeral joint, the large ball-and-socket joint where the humerus joins the scapula. The smooth, rounded head of the humerus rests against the socket in the scapula. The joint is covered by a tough, flexible protective capsule and is heavily reinforced by ligaments that stretch across the joint. The ends of the bones where they meet at the joint are covered with a layer of cartilage that reduces friction and absorbs shock. A thin membrane, the synovial membrane, lines the socket and lubricates the joint with synovia. Further cushioning and lubrication are provided by fluid-filled sacs called bursae. Disorders of the shoulder include bursitis and dislocation.

ad·he·sive cap·su·li·tis

Synonym(s): frozen shoulder
A shoulder with incapacitating pain due to bursitis and inflammation due to 1º or 2º osteoarthritis, rheumatoid arthritis, cuff tear arthropathy and the clinically similar ‘Milwaukee shoulder,’ postmastectomy, avascular necrosis, calcific tendonitis and tearing of the rotator cuff muscles

frozen shoulder

Adhesive capsulitis of shoulder.

frozen shoulder

Painful, persistent stiffness of the shoulder joint that restricts normal movement. The condition affects middle-aged people and usually follows injury or over-enthusiastic exercising. It may also complicate a heart attack (MYOCARDIAL INFARCTION) or STROKE, or may occur for no known reason. It is due to inflammation of the capsule of the joint, leading to thickening, and usually settles spontaneously within 2 years.

Frozen shoulder

A shoulder that becomes scarred and cannot move.

frozen shoulder

also known as adhesive capsulitis. Condition of unknown aetiology, which results from shrinkage and scarring of the capsule in a previously normal joint. Symptoms include pain (lasting months) with stiffness, inflammation and significant restriction of movement (lasting months to years), making everyday activities, such as dressing and brushing hair, difficult. Most common in those aged 50+ and may result from injury or be associated with a number of conditions, e.g. heart disease, thyroid disease or diabetes. Treatment includes adequate pain control and a daily exercise programme; corticosteroid injections and manipulation under anaesthetic are sometimes used.
