Calcific Tendonitis of the Shoulder: Symptoms, Causes, and Treatment

Symptoms of Calcification in the Shoulder

The symptoms of calcification in the shoulder can vary depending on the stage of calcification and individual pain sensitivity. 

Pain

Pain is the most common symptom of calcification in the shoulder. It can manifest in different ways and at varying levels of intensity:

• Mild pain: Initially, the pain may be mild and occur only during specific movements, such as lifting the arm overhead, reaching behind the back, or carrying heavy objects.
• Chronic pain: Over time, the pain may become chronic and persist even at rest. Some people experience constant pain that worsens during physical activity.
• Nocturnal pain: Pain is often more pronounced at night, potentially disrupting sleep. Finding a comfortable sleeping position may become difficult due to the pain, leading to sleepless nights and fatigue.

Limited Mobility

Calcification can cause limited mobility of the shoulder joint, impacting daily life.

• Difficulty lifting the arm: People often notice difficulties lifting the arm overhead, which can hinder daily tasks such as dressing, combing hair, or reaching items on higher shelves.
• Restricted movement: Movement restrictions can also occur when moving the arm sideways or behind the back. This restriction may affect the ability to engage in sports activities and other physical tasks.
• Pain with movement: Any attempt to move the shoulder joint may be accompanied by pain, further limiting mobility and causing discomfort.

Swelling and Tenderness

The shoulder may become swollen and tender to touch, which is another characteristic symptom of calcification.

• Swelling: Calcium deposits can cause inflammation in the surrounding tissue, leading to swelling of the shoulder joint. The swelling may be visible or felt as tension in the joint.
• Tenderness to touch: The shoulder may become tender to pressure or touch, adding to the discomfort. For some individuals, the tenderness is so severe that they avoid any contact with the shoulder.
• Joint stiffness: Inflammation and swelling can also cause a feeling of stiffness in the joint, making movement even more difficult and painful.

Crepitus

Crepitus refers to sensations of cracking or grinding in the shoulder that may occur during joint movement:

• Noises during movement: When moving the arm, you may hear or feel cracking, grinding, or rubbing in the shoulder joint. These sounds result from friction between calcium deposits and the surrounding tissue.
• Discomfort: Crepitus may cause discomfort or pain, further restricting mobility and increasing the feeling of joint stiffness.
• Worsening of symptoms: Although crepitus is not always painful, it can signal worsening calcification and increased wear on the tendons and other structures in the shoulder.

Calcification in the shoulder can be extremely unpleasant and disruptive, but with proper diagnosis and treatment, it is possible to effectively manage symptoms and improve quality of life. If you notice any of these symptoms, consult a doctor or physiotherapist for further treatment advice.

Causes of Calcification in the Shoulder

Exactly why calcium salts deposit in the tendons of the rotator cuff is not entirely clear, but there are some factors that may contribute to the development of calcification.

Degenerative Changes

With aging, natural degenerative changes occur in the body. 

• Natural wear and tear: The tendons and ligaments in the shoulder naturally wear down over time as part of the aging process. This wear can cause microdamage, triggering repair processes in the body.
• Tissue weakening: With age, the elasticity and strength of tendons decrease, which may lead to calcium deposition as part of the body’s mechanism to strengthen weakened tissues.
• Inflammatory response: Degenerative changes are often accompanied by inflammation, which can contribute to the accumulation of calcium deposits in the affected tendons.

Overuse

Overuse of the shoulder joint is a common cause of calcification, particularly in people who frequently perform repetitive movements:

• Sports activities: Sports that involve frequent overhead movements, such as tennis, swimming, or volleyball, can overburden the shoulder joint and tendons. Repeated movements can cause microdamage and inflammation, leading to calcification.
• Occupational activities: Jobs that require repetitive movements or lifting heavy loads can also contribute to overuse of the shoulder joint. Workers in construction, painters, and others who frequently raise their arms overhead are particularly at risk.
• Hobbies: Hobbies like gardening, painting, or playing musical instruments that require repetitive movements can contribute to overuse and eventual calcification.

Injuries

Injuries to the shoulder joint can trigger processes leading to calcification:

• Strains and tendon tears: Injuries such as strains or tears in the tendons can trigger an inflammatory process that leads to calcium deposition. Damaged tendons are more susceptible to calcification than healthy ones.
• Bruises: Strong impacts or falls causing injuries to the shoulder joint can trigger inflammation, increasing the risk of calcification.
• Surgical procedures: Previous surgeries on the shoulder can also contribute to the development of calcification as they can cause inflammation and repair processes leading to calcium deposition.

Metabolic Factors

Disruptions in calcium and mineral metabolism in the body can contribute to calcium deposition in tendons:

• Calcium imbalance: Disruptions in calcium metabolism, such as hypercalcemia (elevated calcium levels in the blood), can increase the risk of tendon calcification.
• Hormonal changes: Hormonal imbalances affecting mineral metabolism can contribute to calcium deposition. For example, changes in parathyroid hormone levels, which regulate calcium levels in the body, can influence calcification.
• Genetic factors: Certain genetic predispositions can affect mineral metabolism and increase the risk of developing calcification in tendons.
• Diet: A diet low in calcium or vitamin D can affect bone and tendon health, contributing to calcium deposition as a compensatory mechanism.

Understanding these factors is essential for the prevention and treatment of calcification in the shoulder. While not all causes can be avoided, a healthy lifestyle and proper care of the shoulder joint can reduce the risk of developing this painful condition.

Treatment of Calcification in the Shoulder

Treatment of calcification in the shoulder depends on the severity of symptoms and the extent of calcification. The goal of treatment is to relieve pain, improve mobility, and prevent further damage. 

Conservative Treatment

Conservative treatment involves non-invasive methods to reduce symptoms and improve the function of the shoulder joint:

• Rest: Avoiding activities that cause pain is crucial to preventing further damage. Rest allows the tendons to begin healing without additional strain.
• Ice packs: Regular application of ice packs to the affected area helps reduce inflammation and pain. Ice can be applied several times a day for 15–20 minutes.
• Nonsteroidal anti-inflammatory drugs (NSAIDs): These medications reduce inflammation and relieve pain. It is important to follow the doctor’s instructions on the dosage of these medications.

Physiotherapy

Physiotherapy is a key component in treating calcification in the shoulder and includes various techniques to improve mobility, strength, and function of the shoulder joint:

• Ultrasound therapy: Use of high-frequency sound waves to promote the breakdown of calcium deposits and improve blood circulation. Ultrasound therapy helps reduce inflammation and supports natural healing processes.
• Manual therapy: Therapists use manual techniques to mobilize the joint and reduce muscle tension. Manual therapy can help alleviate pain and improve joint function.
• TECAR therapy: Use of radiofrequency energy to accelerate healing and reduce pain.
• Specialized kinesiological exercises: Customized exercise programs to strengthen the rotator cuff muscles. Kinesiological exercises help improve the stability and strength of the shoulder joint.
• Laser therapy: Use of laser light to stimulate cellular metabolism and promote the breakdown of calcium. Laser therapy helps reduce pain and accelerates the healing process.
• HiTOP high-tone electrical stimulation: High-frequency electrical stimulation to stimulate cellular metabolism. This therapy enhances cellular metabolism and accelerates calcium breakdown.
• Extracorporeal Shock Wave Therapy (ESWT): A non-invasive method using shock waves to break down calcium deposits and stimulate natural tissue repair. The therapy enhances blood circulation and natural healing processes, helping to relieve pain and improve shoulder joint function. 

Corticosteroid Injections

Corticosteroid injections can quickly reduce pain and inflammation:

• Quick relief: Corticosteroid injections provide rapid and effective symptom relief. They have anti-inflammatory effects and can significantly reduce pain.
• Limited use: Long-term use of corticosteroids is not recommended due to potential side effects.

Arthroscopic Surgery

If conservative treatment does not provide relief, arthroscopic surgery may be recommended:

• Minimally invasive: Arthroscopic surgery is a minimally invasive method that allows the surgeon to remove calcium deposits using a small camera and specialized instruments.
• Short recovery time: As the procedure is less invasive, recovery is usually shorter and less painful compared to traditional open surgery.
• Repair of tendon damage: In addition to removing calcifications, the surgeon can repair any tendon damage during the procedure, further improving joint function.

A holistic approach combining various therapeutic techniques is the most effective way to treat calcification in the shoulder. It is crucial for patients to strengthen the rotator cuff muscles during rehabilitation to ensure the long-term success of the treatment. Consult a healthcare professional to determine the most suitable treatment plan for your specific needs.

Prevention of Calcification in the Shoulder

While it is not entirely possible to prevent calcification in the shoulder, some measures can help reduce the risk of developing this condition. Here are the key prevention guidelines:

Avoiding Repetitive Strain

• Adjusting activities: Try to reduce or adapt activities that involve repetitive overhead arm movements. Such activities include working at height, playing certain sports, or performing repetitive motions in daily tasks.
• Recognizing early signs: If you notice pain or discomfort in the shoulder during certain movements, avoid continuing these activities and take time to rest and recover.
• Regular breaks: If your work or sport involves repetitive movements, take frequent short breaks to reduce strain on the shoulder joint and prevent overuse.

Regular Exercise

• Muscle strengthening: Maintain strong shoulder joint muscles through regular physical activity. Strengthening exercises such as weightlifting, resistance band exercises, and stabilization exercises help improve the joint's strength and stability.
• Stretching: Incorporate stretching exercises into your workout routine to maintain flexibility in the muscles and ligaments around the shoulder joint. Stretching helps prevent stiffness and reduces the risk of injury.
• Aerobic exercise: Regular aerobic exercise such as walking, running, or swimming contributes to overall fitness and joint health.

Proper Technique

• Ergonomics at work: If you engage in sports or work that requires repetitive movements, ensure you use proper technique and ergonomics. This includes maintaining correct posture, using appropriate equipment, and performing proper movements.
• Training and education: Work with a trainer or physiotherapist to learn the correct techniques for exercises and other activities. This helps prevent improper movements that can strain the shoulder joint.
• Workplace adjustment: Ensure your work environment is ergonomically friendly. Adjust the height of work surfaces and use ergonomic tools and equipment to minimize the risk of injury.

Caring for Overall Health

• Balanced diet: Maintain a balanced diet rich in nutrients that support bone and joint health. Include foods rich in calcium, vitamin D, magnesium, and omega-3 fatty acids.
• Maintaining a healthy weight: Excess weight can strain the joints, including the shoulders. Maintaining a healthy weight reduces joint pressure and lowers the risk of degenerative changes.
• Hydration: Drink enough water, as proper hydration supports the health of joints and connective tissue.
• Regular health check-ups: Visit your doctor regularly and monitor your overall health. Your doctor can advise you on additional measures to prevent shoulder issues, especially if you are at increased risk of calcification due to genetic or other factors.

By following these guidelines, you can reduce the risk of developing calcification in the shoulder and maintain the health and functionality of your shoulder joints.
