adhesive c. of shoulder A condition that causes shoulder pain with restricted movement and , eventually, fibrosis of the glenohumeral joint. This may follow bursitis or tendinitis of the shoulder or may be associated with systemic conditions such as chronic pulmonary disease, myocardial infarction, or diabetes mellitus. Prolonged immobility of the arm favors development of adhesive capsulitis. The condition is more common in women after age 50. It may resolve spontaneously 12 to 18 months after onset or may result in permanent restriction of movement. Treatment includes injection of glucocorticoids; use of nonsteroidal anti-inflammatory agents and physical therapy may provide symptomatic relief; early range-of-motion exercises following an injury may prevent development of the disease; and manipulation of the shoulder while the patient is anesthetized may be of benefit.SYN: frozen shoulder; pericapsulitis.
