What is frozen shoulder?
Frozen shoulder (adhesive capsulitis) is stiffness, pain, and limited range of movement in your shoulder. It may happen after an injury or overuse or from a disease such as diabetes or a stroke. The tissues around the joint stiffen, scar tissue forms, and shoulder movements become difficult and painful. The condition usually comes on slowly, then goes away slowly over the course of a year or more.
What causes frozen shoulder?
Frozen shoulder can develop when you stop using the joint normally because of pain, injury, or a chronic health condition, such as diabetes or a stroke. Any shoulder problem can lead to frozen shoulder if you do not work to keep full range of motion.
Frozen shoulder occurs:
- After surgery or injury.
- Most often in people 40 to 70 years old.
- More often in women (especially in postmenopausal women) than in men.
- Most often in people with chronic diseases.
How is frozen shoulder diagnosed?
Your doctor may suspect frozen shoulder if a physical exam reveals limited shoulder movement. An X-ray may be done to see whether symptoms are from another condition such as arthritis or a broken bone.
How is it treated?
Treatment for frozen shoulder usually starts with nonsteroidal anti-inflammatory drugs (NSAIDs) and application of heat to the affected area, followed by gentle stretching. Ice and medicines (including corticosteroid injections) may also be used to reduce pain and swelling. And physical therapy can help increase your range of motion. A frozen shoulder can take a year or more to get better.
If treatment is not helping, surgery is sometimes done to loosen some of the tight tissues around the shoulder. Two surgeries are often done. In one surgery, called manipulation under anesthesia, you are put to sleep and then your arm is moved into positions that stretch the tight tissue. The other surgery uses an arthroscope to cut through tight tissues and scar tissue. These surgeries can both be done at the same time.
Can frozen shoulder be prevented?
Gentle, progressive range-of-motion exercises, stretching, and using your shoulder more may help prevent frozen shoulder after surgery or an injury. Experts don't know what causes some cases of frozen shoulder, and it may not be possible to prevent these. But be patient and follow your doctor's advice. Frozen shoulder nearly always gets better over time.
