Frozen shoulder

Overview of Frozen shoulder

Frozen shoulder, also known as adhesive capsulitis, is a condition marked by pain, stiffness, and limited movement in the shoulder joint.


Typically, frozen shoulder affects individuals between the ages of 40 and 60, with women being more prone to the condition than men.


The exact cause of frozen shoulder remains unclear, but it is thought to involve inflammation and the development of adhesions within the shoulder joint. Those with diabetes, thyroid disorders, rheumatoid arthritis, or those who have been immobile for extended periods due to surgery or injury are more likely to develop this condition.


Treatment typically involves a combination of pain-relief medications, anti-inflammatory drugs, and physical therapy to improve mobility. In more severe cases, procedures such as joint distension or manipulation under anesthesia may be necessary.

Symptoms Of Frozen shoulder

The hallmark symptoms of frozen shoulder include:

  • Persistent pain and stiffness in the shoulder
  • Difficulty lifting the arm above the head
  • Trouble extending the arm across the body or reaching behind the back


Frozen shoulder typically progresses through three distinct stages:


Painful or ‘Freezing’ Phase

  • This stage is marked by gradual shoulder pain that worsens over time, often feeling deep within the joint and intensifying at night. As pain increases, the shoulder’s range of motion decreases, making activities such as dressing or reaching more challenging. This phase can last from 6 weeks to 9 months.


Stiffness or ‘Frozen’ Phase

  • During this phase, pain may lessen but stiffness becomes more severe, restricting the shoulder's mobility. Lifting the arm and performing regular tasks becomes extremely difficult, and the arm’s function is significantly limited. This stage typically lasts from 4 to 12 months.


Resolution or ‘Thawing’ Phase

  • In this final phase, the shoulder’s range of motion gradually improves, though full recovery may take several months to years. Pain tends to decrease, but some discomfort may still be present during movement. Functionality improves, making daily tasks easier. Complete recovery and strength can take anywhere from 5 months to 2 years.


Triggering Factors Of Frozen shoulder

Frozen shoulder occurs when inflammation and thickening develop within the joint capsule, though the exact cause remains unknown. It may be linked to several contributing factors, including:


  • Intrinsic Factors: This type is associated with issues affecting the tendons surrounding the shoulder joint, such as tendonitis or tears. It may also involve calcium deposits in the tendons.


  • Extrinsic Factors: These factors are linked to issues outside the shoulder joint, including previous breast surgery on the same side, nerve problems in the neck, chest wall tumors, prior strokes, or bone-related issues in the shoulder region.


  • Systemic Diseases: Conditions that affect the body as a whole, such as diabetes, thyroid disorders (both hypothyroidism and hyperthyroidism), or adrenal gland issues, can also increase the risk of developing frozen shoulder.


Types Of Frozen shoulder


Potential Risks for Frozen shoulder

Age:

Frozen shoulder is more commonly seen in individuals between the ages of 40 and 60 years.


Gender:

Women are at a higher risk of developing frozen shoulder compared to men. Hormonal changes during perimenopause, menopause, and pregnancy may play a role in this increased susceptibility.


Previous Shoulder Injury or Surgery:

Those who have had prior shoulder injuries or surgeries are more likely to develop frozen shoulder.


Immobilization:

Any situation or injury that leads to prolonged immobility of the shoulder joint can increase the risk of frozen shoulder. This includes conditions like fractures, injuries, or extended periods of bed rest.


Systemic Diseases:

Certain medical conditions that affect the body as a whole, such as thyroid disorders (both hyperthyroidism and hypothyroidism), cardiovascular disease, and Parkinson's disease, have been linked to a higher risk of frozen shoulder.


Autoimmune Conditions:

Individuals with autoimmune diseases, such as rheumatoid arthritis, are at an increased risk of developing frozen shoulder.


Dupuytren's Disease:

This condition, which causes thickening and tightening of the connective tissue in the hands, has been associated with a higher risk of frozen shoulder.

Diagnosis Of Frozen shoulder

Diagnosing frozen shoulder involves reviewing the medical history, conducting a physical exam, and possibly performing imaging tests:


Medical History:

The doctor will start by asking about your symptoms and medical background. They will inquire about the shoulder pain, how long you've had it, any prior injuries or medical conditions, and whether specific activities might have triggered the issue.


Physical Examination:

During the physical exam, the healthcare provider will evaluate the range of motion, strength, and any specific movements that cause pain or discomfort in the shoulder. They will also look for signs of inflammation, swelling, or muscle weakness in the affected shoulder.


Imaging Tests:

To confirm the diagnosis and rule out other potential causes of shoulder pain, the doctor may recommend imaging tests:

  • X-rays: X-rays can help detect conditions like arthritis or bone spurs that could be contributing to the symptoms.
  • MRI (Magnetic Resonance Imaging): MRI provides detailed images of soft tissues such as muscles, tendons, and ligaments, allowing the doctor to assess any structural problems in the shoulder.
  • Ultrasound: This imaging method can also be used to examine the shoulder's soft tissues and identify any abnormalities.


Preventive Measures Of Frozen shoulder

Here are some simple and effective steps you can take to reduce the risk of developing frozen shoulder:


Daily Shoulder and Back Stretching:

Take a few minutes each day to gently stretch your shoulder and back muscles. This helps keep them flexible and resilient.


Maintain Proper Posture and Ergonomics:

Pay attention to your posture and body mechanics during daily activities. Avoid slouching or hunching for extended periods to reduce stress on your shoulder joints.


Warm-up Before Exercise:

Ensure you properly warm up your shoulder muscles before engaging in physical activities that involve heavy shoulder use.


Balanced Exercise Routine:

Avoid overloading the shoulder joint and incorporate a varied exercise routine. Focus on strengthening the muscles around the shoulder, including the rotator cuff muscles.


Prevent Traumatic Injuries:

Take measures to protect your shoulder from traumatic injuries, such as wearing appropriate protective gear during sports and physical activities.


Adopt a Healthy Lifestyle:

A balanced diet, regular exercise, and proper rest can contribute to overall joint health and help prevent frozen shoulder.


Manage Diabetes:

Since diabetes can increase the risk of developing frozen shoulder, it's essential to keep blood sugar levels under control to minimize this risk.


Avoid Prolonged Immobilization:

Try not to leave your shoulder immobile for extended periods, particularly after an injury or surgery. It’s important to follow proper rehabilitation protocols and gently move the shoulder joint within a pain-free range as soon as possible.


Pay Attention to Your Body:

If you experience any shoulder pain, stiffness, or a reduced range of motion, don’t ignore it. Early medical intervention can help prevent the condition from worsening.


Doctor to Visit

If shoulder pain becomes persistent, especially if it interferes with daily activities, or if stiffness doesn't improve and pain worsens at night, it’s essential to consult a doctor for a timely diagnosis.

Specialists who can assist with diagnosis and treatment include:


  • General Physician: They help diagnose and provide early treatment for frozen shoulder, and may refer you to an orthopedic specialist if necessary.
  • Orthopedic Surgeon: Orthopedic specialists treat frozen shoulder with a range of interventions, from medications to surgery, aiming to restore function and relieve pain.
  • Physiotherapist: A physiotherapist designs personalized exercises to improve shoulder mobility, reduce pain, and prevent stiffness. They may also use techniques like heat and electrical stimulation.
  • Rehabilitation Specialist: These experts focus on non-surgical methods to restore shoulder function and mobility.


Treatment Of Frozen shoulder

Treatment for frozen shoulder can be broadly categorized into conservative (non-operative) methods and surgical approaches. Most cases are managed effectively with non-operative methods, with surgery considered for severe cases that do not improve with conservative treatments.


I. Conservative (Non-Operative) Methods:

  1. Oral Pain Relief Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, diclofenac, and paracetamol, are commonly prescribed to alleviate pain and inflammation. These, combined with physiotherapy, are the cornerstone of treatment for frozen shoulder.
  2. Corticosteroid Injections: Corticosteroid injections can help reduce inflammation and provide pain relief. However, they are used sparingly due to potential side effects.
  3. Hydrodistention: This involves injecting sterile water into the joint capsule to stretch the tissue, making it easier to move the joint. This may sometimes be combined with a steroid injection.
  4. Electrical Stimulation: Two common methods include:
  • Transcutaneous Electrical Nerve Stimulation (TENS): This therapy uses electrical currents to relieve pain and promote muscle relaxation.
  • Ultrasound Therapy: Ultrasound is used to enhance blood circulation and accelerate tissue healing in the affected area.


II. Operative (Surgical) Methods

Surgery is typically considered when conservative treatments do not provide significant relief.

  1. Arthroscopic Capsular Release (ACR) Surgery: This minimally invasive procedure uses an arthroscope to cut through the tight joint capsule, releasing adhesions and improving shoulder mobility.
  2. Manipulation Under Anesthesia (MUA): In this procedure, the scar tissue and adhesions are broken under anesthesia. It is often done alongside arthroscopic capsular release. Post-surgery, physical therapy is usually required to regain full shoulder function.


III. Post-operative Rehabilitation

Rehabilitation begins shortly after surgery to prevent stiffness and aid recovery.

It includes gentle range of motion exercises, stretching, and progressive strengthening routines. Regular guidance from healthcare professionals is key to ensuring successful recovery.


Heat therapy and manual techniques may also be used to relax muscles and increase circulation. Consistent physiotherapy ensures gradual restoration of shoulder function.

Health Complications Of Frozen shoulder

Lingering Pain:

After the main phase of frozen shoulder subsides, some people may experience persistent pain in the affected shoulder, even after the range of motion has improved.


Residual Stiffness:

Even after frozen shoulder resolves, some individuals may continue to have lingering stiffness or limitations in shoulder movement.


Fracture of the Humerus:

Rarely, if frozen shoulder is treated too aggressively, it can lead to a fracture in the upper arm bone (humerus), particularly in those with weakened bones, such as from osteoporosis.


Biceps Tendon Rupture:

The biceps tendon, which is part of the shoulder joint, can tear if excessive force is applied during a procedure called Manipulation under Anesthesia (MUA). This could result in increased pain and difficulty moving the shoulder.

Alternative Therapies For Frozen shoulder

There are several complementary and alternative treatments that may help manage frozen shoulder. However, it’s important to consult with your healthcare provider before trying any of these approaches:


Yoga and Stretching Exercises

Practicing specific yoga poses can help alleviate the symptoms of frozen shoulder. Consider incorporating the following poses into your routine:

  • Garudasana
  • Paschim Namaskarasana
  • Ustrasana
  • Dhanurasana
  • Purvottanasana

Ensure that you receive proper instruction from a qualified yoga teacher to avoid worsening the condition.


Tai Chi

Tai Chi is a low-impact, meditative martial art that focuses on slow, flowing movements. It can be beneficial in improving balance, posture, and flexibility, including shoulder mobility.


Cupping Therapy

Cupping therapy involves placing cups on the skin to create suction, which may increase blood circulation and relieve muscle tension. This technique can be applied to the affected shoulder area.


Acupuncture

Acupuncture involves inserting thin needles into specific points on the body to enhance energy flow. Some people with frozen shoulder have reported relief from pain and improved shoulder movement through acupuncture.


Moxibustion

Moxibustion is a technique that involves burning dried mugwort (moxa) near acupuncture points. The heat is believed to stimulate blood and energy flow, which may help reduce pain and inflammation.
