Frozen shoulder, also called adhesive capsulitis, occurs when the tissues of the shoulder capsule become thick, stiff, and inflamed. It is most common in people between the ages of 40 and 60, and occurs in women more often than men.
Causes and risk factors:
The cause of this condition is not fully understood. It may occur after the shoulder has been immobilized for a period of time due to a surgery or injury. Frozen shoulder also occurs more in people with diabetes and certain medical problems such as Parkinson’s disease, hypothyroidism, hyperthyroidism, and cardiac disease.
The main symptom is limited motion (or freezing) of the shoulder. It can also be accompanied by a dull, aching pain on the outer shoulder area.
Most patients improve with non-surgical treatment options, including anti-inflammatory medications, cortisone injections, and physical therapy. Surgery may be recommended if the condition does not improve.
