The shoulder is a unique anatomical structure with an extraordinary range of motion (ROM) that allows us to interact with our environment. A loss of mobility of this joint will cause significant morbidity. Adhesive capsulitis is a poorly understood musculoskeletal condition that can be disabling.
Symptoms and signs of a frozen shoulder include pain, stiffness, and loss of range of motion of the shoulder. Treatment for frozen shoulder involves range-of-motion exercises and, sometimes, corticosteroids and numbing medications injected into the joint capsule. In a small percentage of cases, arthroscopic surgery may be indicated to loosen the joint capsule so that it can move more freely. Treatment for frozen shoulder usually starts with nonsteroidal anti-inflammatory drugs (NSAIDs) and application of heat to the affected area.
The prevalence of frozen shoulder is estimated to be 2 to 5 percent of the general population . The condition is most common in the fifth and sixth decades of life, with the peak age in the mid-50s. Onset before the age of 40 is rare. Women are more often affected than men.
