Frozen Shoulder: Causes, Symptoms, Risk Factors, Diagnosis

Frozen shoulder is also known as adhesive capsulitis, and it results in pain and stiffness in the shoulder joint. Usually, indications and symptoms appear gradually at first and then worsen. After a year or three, the symptoms normally become better.

A frozen shoulder is a risk associated with prolonged immobilization of the shoulder. This could happen after an arm break or surgery.

Exercises involving range of motion are a part of the frozen shoulder treatment regimen. Occasionally, as part of treatment, the joint is injected with corticosteroids and numbing agents. Rarely, arthroscopic surgery is necessary to release the joint capsule and promote joint movement.

It is rare for frozen shoulders to recur in the same shoulder. But in certain people, it might also appear in the opposite shoulder, usually within five years.

Causes Of Frozen Shoulder 

The shoulder joint is surrounded by a capsule made of connective tissue. Frozen shoulder is a condition in which the capsule enclosing the shoulder joint becomes increasingly tight and thick, hence restricting movement.

It's unclear why this happens to some people. On the other hand, extended shoulder immobilization such as after surgery or an arm fracture raises the probability of its occurrence.

Symptoms Of Frozen Shoulder 

Frozen shoulder often develops gradually over three stages.

• The freezing phase: The shoulder's range of motion is limited, making it uncomfortable to move. During this phase, two to nine months pass.
• Frozen state: There can be less pain at this phase. However, the shoulder becomes more rigid. It becomes difficult to function. In this phase, four to twelve months pass.
• Phase of defrosting: The shoulder's range of motion begins to expand. This stage lasts between four and six months.
• Sometimes the pain gets worse at night and keeps you from sleeping.

Risk Factors Of Frozen Shoulder 

Few things can increase your risk of developing a frozen shoulder.

• Age and gender 
• The prevalence of frozen shoulders is higher in adults over 40, particularly in women.
• Reduced movement or lack of movement

Frozen shoulder is more common in people who have had to keep their shoulder somewhat immobilized. Movement restrictions can result from a variety of factors, including:

• Damage to the rotator cuff
• Broken arm
• Stroke
• Recovery after surgery
• Systemic diseases

Some diseases seem to be associated with a higher incidence of frozen shoulders. The following circumstances could increase the risk:

• Diabetes
• Overactive thyroid, or hyperthyroidism,
• Hypothyroidism
• Heart-related disorders
• Parkinson disease

Diagnosis Of Frozen Shoulder 

During the physical examination, you can be asked to move your arm in particular ways by a medical practitioner. This is to take an active range of motion measurement and feel for any pain in your arm. The next exercise you could be asked to perform is passive range of motion, which is letting go of your muscles while the clinician moves your arm. Frozen shoulder affects range of motion, both passive and active.

For the most part, frozen shoulders can be diagnosed based just on symptoms and indicators. Imaging tests, such as MRIs, ultrasounds, and X-rays, can help rule out other conditions.

Treatment Of Frozen Shoulder 

The major objectives of treating a frozen shoulder are to reduce shoulder pain and maintain the shoulder range of motion.

Medications

Both aspirin and ibuprofen (Advil, Motrin IB, and other brands) are anti-inflammatory drugs that can help reduce pain and swelling associated with frozen shoulders. In such cases, a doctor may prescribe stronger pain relievers and analgesics.

Therapy

A physical therapist can teach you range-of-motion exercises to help you restore your shoulder's range of motion. You have to commit to completing these exercises if you want to restore as much movement as possible.

Surgery

Most frozen shoulders go away on their own after 12 to 18 months. For more serious or persistent symptoms, further treatments include:

• Injections of steroids: Injections of corticosteroids into the shoulder joint may help ease pain and enhance shoulder mobility, especially if given soon after a frozen shoulder begins.
• Hydrodilatation: Injecting sterile water into the joint capsule will stretch the tissue and promote joint movement. Sometimes this is used with a steroid injection.
• Adjusting the shoulders: Because you will be sleeping due to the administration of a general anesthetic, you will not experience any pain during this surgery. The medical practitioner then moves the shoulder joint in different ways to help the tense tissue release.
• Surgery: Surgery for frozen shoulders is not very common. If all other options are exhausted, surgery might be utilized to remove scar tissue from the inside of the shoulder joint. In order to implant tiny instruments within the joint with the help of a tiny camera, tiny incisions are usually made during this surgery (arthroscopy).

Prevention Of Frozen Shoulder 

One common cause of a frozen shoulder is being unable to move the shoulder while recovering from a shoulder injury, broken arm, or stroke. If you have had an injury that restricts your range of motion in your shoulder, talk to your doctor about exercises that can help you maintain that mobility.
