Frozen shoulder

Adhesive capsulitis; Shoulder pain - frozen

Frozen shoulder is a condition in which the shoulder is painful and loses motion because of inflammation.

Causes

The capsule of the shoulder joint has ligaments that hold the shoulder bones to each other. When the capsule becomes inflamed, the shoulder bones are unable to move freely in the joint.

Most of the time, there is no cause for frozen shoulder. Women 40 to 70 years old are most affected, however, men can also get the condition.

Risk factors include:

  • Diabetes
  • Thyroid problems
  • Changes in your hormones, such as during menopause
  • Shoulder injury
  • Shoulder surgery
  • Open heart surgery
  • Cervical disk disease of the neck

Symptoms

Main symptoms of a frozen shoulder are:

  • Pain
  • Decreased motion of the shoulder
  • Stiffness

Frozen shoulder can start with pain without any cause or minor trauma. The pain may be severe and prevent you from moving your arm. This lack of movement can lead to stiffness and even less motion. Over time, you are not able to do movements such as reaching over your head or behind you.

Exams and Tests

Your health care provider will ask about your symptoms and examine your shoulder. A diagnosis is often made just with a clinical exam when you are not able to rotate your shoulder.

You may have x-rays of the shoulder. This is to make sure there is no other problem, such as arthritis or calcium deposits. Sometimes, an MRI exam shows inflammation, but these types of imaging tests are usually not needed to diagnose frozen shoulder.

Treatment

Pain is treated with NSAIDs and steroid injections. Steroid injections and physical therapy can improve your motion.

It can take a few weeks to see progress. It may take as long as 9 months to a year for complete recovery. Physical therapy may be intense and needs to be done every day.

Left untreated, the condition often gets better by itself within 2 years with little residual loss of motion. However, your other medical conditions may make the process last longer.

Risk factors for frozen shoulder, such as menopause, diabetes or thyroid problems, should also be treated.

Surgery is recommended if nonsurgical treatment is not effective. This procedure (shoulder arthroscopy) is done under anesthesia. During surgery the scar tissue is released (cut) by bringing the shoulder through a full range of motion. Arthroscopic surgery can also be used to cut the tight ligaments and remove the scar tissue from the shoulder. After surgery, you may receive pain blocks (shots) so you can do physical therapy.

Follow instructions on caring for your shoulder at home. 

Outlook (Prognosis)

Treatment with physical therapy and NSAIDs often restores motion and function of the shoulder within a year. Even untreated, the shoulder may get better by itself in 2 years.

After surgery restores motion, you must continue physical therapy for several weeks or months. This is to prevent the frozen shoulder from returning. If you do not keep up with physical therapy, the frozen shoulder may come back.

Possible Complications

Complications may include:

  • Stiffness and pain continue even with therapy
  • The arm can break if the shoulder is moved forcefully during surgery

When to Contact a Medical Professional

If you have shoulder pain and stiffness and think you have a frozen shoulder, contact your provider for evaluation, referral, and treatment.

Prevention

Early treatment may help prevent stiffness. Call your provider if you develop shoulder pain that limits your range of motion for an extended period.

People who have diabetes or thyroid problems will be less likely to get frozen shoulder if they keep their condition under control.

    Swelling, damage, or bone changes around the rotator cuff in your shoulder can cause pain that puts a kink in the activities of your life. Let's talk about shoulder pain. The rotator cuff is a group of muscles and tendons that attach to the bones of your shoulder joint. The group allows your shoulder to move and keep it stable. The most common cause of shoulder pain is when rotator cuff tendons become inflamed or trapped in your shoulder. This is called rotator cuff tendinitis, or irritation of these tendons and inflammation of the bursa, small slippery fluid filled sacs that the tendons glide over. A rotator cuff tear, when one of the tendons is torn from overuse or injury, can also cause intense shoulder pain. Other causes of shoulder pain can include arthritis, bone spurs - bony projections, a broken shoulder bone, frozen shoulder, when the muscles, tendons, and ligaments in your shoulder become stiff, and shoulder dislocation. Most of the time, you can take care of your shoulder pain at home. Try putting ice on your shoulder for 15 minutes, then leave it off for 15 minutes, three or four times a day for a few days. Make sure you wrap the ice in cloth, so it doesn't give you frostbite. Take ibuprofen to reduce pain and swelling. Slowly return to your regular activities once you start feeling less pain. Sudden shoulder pain can be a sign of a heart attack. Call Emergency Services if you have sudden pressure or crushing pain in your shoulder, especially if the pain starts in your chest, jaw, or neck. If you fall on your shoulder and feel sudden intense pain, you should see a doctor because you may have torn rotator cuff or dislocated your shoulder. If you have had shoulder pain before, try using ice and ibuprofen after exercising. Learn proper exercises to stretch and strengthen your rotator cuff tendons and shoulder muscles. Also, physical therapy can help. Make an appointment and talk about your options.
