Supraspinatus tendonitis: Understanding, Treatment and Prevention

Introduction

Supraspinatus tendonitis is a painful condition that affects the shoulder, often caused by inflammation or irritation of the supraspinatus muscle tendon. This muscle, located in the upper part of the shoulder, plays a crucial role in the mobility and stability of this complex joint. Understanding aspects of this condition, its treatment and means of prevention is essential for those suffering from this condition or seeking to prevent it.

Understanding Supraspinous Tendonitis

Supraspinatus tendonitis often occurs as a result of repetitive arm movements, overuse, or direct trauma. Symptoms include persistent shoulder pain, made worse by moving the arm overhead. The pain may also radiate to the neck and arms. Activities such as lifting, throwing, and even simple movements can become painful for those suffering from this condition.

Anatomically, the supraspinatus tendon passes under the shoulder bone, called the acromion, in a narrow area called the subacromial strait. When this area is reduced, either by inflammation or anatomical shape, the tendon can become pinched, causing pain and inflammation.

Treatment of Supraspinous Tendonitis

Treatment of supraspinatus tendinitis aims to relieve pain, reduce inflammation, and restore normal functionality to the shoulder. It may include anti-inflammatory medications, physical therapy sessions to strengthen surrounding muscles and improve mobility, and activity modifications to avoid movements that aggravate the condition.

In some cases, when conservative treatments do not provide adequate relief, more advanced options such as corticosteroid injections or, in extreme cases, surgery, may be considered. Surgery may involve releasing the subacromial space to reduce pressure on the tendon.

Prevention of Supraspinous Tendonitis

Prevention of supraspinatus tendonitis relies on practices and habits that minimize risk factors. It is essential to adopt correct technique when performing activities involving the arm, avoiding excessive or repetitive movements that could stress the tendon. Strengthening your shoulder muscles and doing regular stretches can help maintain stability and flexibility in the joint.

Proper management of physical activities, especially for those who engage in repetitive movements in their work or hobbies, is crucial. Frequent breaks, alternating tasks and using ergonomic equipment can help reduce stress on the shoulder.

Anatomy and Function of the Supraspinatus Tendon

Location and Structure

The supraspinatus tendon is a key component of the rotator cuff, a group of four muscles and their tendons that provide stability and facilitate movement of the shoulder joint. It originates from the supraspinatus muscle, which is located in the supraspinous fossa of the scapula (shoulder blade). The tendon then passes under the acromion (a bony projection on the scapula) and inserts onto the greater tubercle of the humerus (the upper arm bone).

• Supraspinatus Muscle: Located in the supraspinous fossa, above the spine of the scapula.
• Tendon Pathway: Travels laterally under the acromion, a bony arch formed by the scapula, to attach to the humerus.
• Insertion Point: Greater tubercle of the humerus, one of the three prominent points of the proximal humerus.

The tendon is susceptible to injury due to its location under the acromion, where it can be compressed, especially during overhead activities.

Role in Shoulder Movement and Stability

The supraspinatus tendon, along with the supraspinatus muscle, plays a crucial role in both the movement and stability of the shoulder.

• Abduction: The primary function of the supraspinatus muscle is to initiate the abduction of the arm, lifting it away from the body. It works in concert with the deltoid muscle to perform this movement.
• Shoulder Stability: The supraspinatus tendon is essential for maintaining the stability of the glenohumeral (shoulder) joint. It helps keep the head of the humerus firmly within the shallow socket of the scapula (glenoid cavity), preventing dislocation and allowing for smooth and coordinated shoulder movements.
• Rotator Cuff Function: As part of the rotator cuff, the supraspinatus tendon contributes to the overall integrity and function of the shoulder. The rotator cuff muscles collectively stabilize the shoulder joint and allow for a wide range of movements, including rotation, lifting, and pushing.

Causes

Supraspinatus tendonitis is usually caused by a combination of factors, including repetitive movements, overuse of the arm, or direct trauma. Here are some of the main causes of supraspinatus tendonitis:

Symptoms

Symptoms of supraspinatus tendonitis can vary in intensity and duration, but they usually occur in the shoulder area and can affect the arm. Here are the common symptoms associated with this condition:

1. Pain: Pain is the most common symptom of supraspinatus tendonitis. It is usually located in the front and side of the shoulder. The pain can be acute or chronic and worsens with arm movements, especially during elevation or extension.
2. Muscle Weakness: Weakness in the muscles surrounding the shoulder, particularly the supraspinatus, may occur. This can lead to difficulty performing specific movements, such as raising your arm above your head.
3. Stiffness: Shoulder stiffness may be felt, limiting range of motion. This can make some daily activities difficult.
4. Sensitivity to Touch: The affected area may be sensitive to touch. Light pressure on the shoulder area can trigger or worsen the pain.
5. Crepitation: Some individuals may feel or hear crepitations or cracking sounds during certain shoulder movements. This may be associated with rubbing of the affected tendons.
6. Nocturnal Pain: Pain may intensify during the night, disrupting sleep. Some individuals may have difficulty finding a comfortable position to sleep due to shoulder pain.
7. Referred Pain: Pain may radiate down the arm, sometimes down to the elbow. This can be confused with problems in other parts of the arm.

Pathophysiology

1. Repetitive Microtrauma: Supraspinatus tendonitis is often the result of repetitive microtrauma to the supraspinatus tendon, which is one of the four rotator cuff muscles located in the shoulder. These microtraumas can be caused by repetitive arm movements, excessive sports activities, heavy lifting or traumatic injuries.
2. Age and Wear: Natural aging and wear of tendons over time can also contribute to the development of tendonitis. As tendons age, they can lose their elasticity and ability to withstand stress, increasing the risk of injury.
3. Vascular Alterations and Blood Circulation Impairment: Repetitive microtrauma can lead to vascular alterations, affecting blood circulation in the area. Impaired vascularity can compromise the ability of tendons to regenerate effectively, leading to progressive degeneration.
4. Inflammatory Process: Microtrauma and tendon degeneration trigger an inflammatory process. Inflammation is a normal response of the body to injury, but if it becomes chronic, it can contribute to tissue deterioration.
5. Fibrosis and Scarring: In response to injury, the body may form scar tissue (fibrosis) in the affected area. Although healing is a natural tissue repair mechanism, excess fibrosis can cause tendons to lose flexibility, compromising their function.
6. Compression and Friction: Inflammation and fibrosis can lead to thickening of the tendons, which increases the risk of compression and friction between the tendons and surrounding bony structures, especially during shoulder movements.
7. Progressive Rotator Cuff Deterioration: Supraspinatus tendonitis can progress to progressive deterioration of the rotator cuff, involving other muscles in this region. This can lead to changes in shoulder biomechanics, further affecting joint stability and function.

Prevention

Prevention of supraspinatus tendonitis is based on practices and habits that aim to reduce the risk of repetitive strain injuries, strengthen the rotator cuff, and maintain the general health of the shoulder. Here are some recommendations to prevent supraspinatus tendonitis:

1. Warm-up and Stretches: Before any physical activity, especially those involving repetitive arm movements, it is essential to do a proper warm-up followed by specific stretches for the shoulder region. This helps improve the flexibility of muscles and tendons, reducing the risk of injury.
2. Muscle Strengthening: A regular program of muscle strengthening exercises, with emphasis on the rotator cuff muscles, can help stabilize the shoulder and reduce stress on the tendons. Targeted exercises, such as external and internal rotations, can be included in the program.
3. Awareness of Movements: Avoid excessive and repetitive movements of the arm, particularly overhead, which could excessively strain the supraspinatus muscle. If your daily or work activity involves repetitive movements, be sure to take regular breaks to allow the shoulder to rest.
4. Improved Posture: Maintaining good posture is crucial for shoulder health. Correct posture can reduce pressure on shoulder structures, minimizing the risk of strains and strain injuries.
5. Stress Management: Stress can contribute to muscle tension, including in the shoulder area. Stress management techniques, such as meditation, deep breathing and yoga, can help relax muscles and prevent excess tension.
6. Avoid Excessive Loads: When exercising or engaging in physical activity, avoid lifting excessive loads, especially if it involves overhead movements. Use proper lifting techniques and seek help if necessary.
7. Maintaining a Healthy Weight: Maintaining a healthy body weight helps reduce the strain on joints, including the shoulder. Excessive weight can increase stress on the rotator cuff tendons.
8. Early Medical Consultation: In case of persistent shoulder pain, consult a healthcare professional at the first signs. Early intervention can help prevent the progression of lesions and put an appropriate treatment plan in place.

Diagnosis and Treatment

The diagnosis and treatment of supraspinatus tendonitis involves a comprehensive medical approach, combining clinical assessment, medical imaging examinations and therapeutic interventions. Here is an overview of the diagnostic process and treatment options associated with this condition.

Diagnostic

1. Clinical Examination: A healthcare professional, usually a doctor or orthopedist, will perform a thorough clinical examination. This may involve questions about medical history, current symptoms, and physical tests to assess shoulder mobility and identify areas of pain.
2. Medical Imaging: Imaging tests such as x-rays, ultrasound or MRI may be ordered to visualize the internal structures of the shoulder. These tests help confirm the diagnosis and assess the extent of damage to the supraspinatus tendon.

Treatment

Treatment of supraspinatus tendinitis aims to relieve pain, reduce inflammation, restore normal shoulder function, and prevent recurrence. Approaches may include:

1. Rest and Ice: The often recommended first step is to reduce activities that aggravate symptoms and apply ice to reduce inflammation. Relative rest allows the tendons to heal.
2. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to reduce inflammation and relieve pain. Pain relievers may also be recommended.
3. Osteopathy: Osteopathy sessions are frequently used to strengthen the rotator cuff muscles, improve shoulder stability and restore mobility. The exercises can be adapted depending on the healing phase.
4. Corticosteroid Injections: In some cases, corticosteroid injections may be given directly into the shoulder joint to reduce inflammation.
5. Shockwave Therapy: This therapeutic modality uses acoustic waves to stimulate tendon healing and reduce pain.
6. Orthotics or Splints: In certain situations, wearing an orthosis or splint may be recommended to limit shoulder movement and allow for better healing.
7. Surgery: If conservative approaches fail and the tendinitis is severe, surgery may be considered. This may involve surgical repair of the supraspinatus tendon.

A Day in the Life of Someone with Supraspinatus Tendinitis

Living with supraspinatus tendinitis can be a daily challenge, affecting not only physical activities but also emotional well-being. This condition, characterized by inflammation of the supraspinatus tendon in the shoulder, often leads to pain and limited mobility. Here’s a glimpse into a typical day for someone managing this condition.

Morning Routine

The day often starts with a sense of stiffness and discomfort in the shoulder. Simple tasks like getting out of bed, brushing teeth, or combing hair can be painful and frustrating. Many find relief in a warm shower, allowing the heat to soothe the inflamed tendon and ease stiffness. Stretching exercises, as recommended by healthcare providers, become a crucial part of the morning routine to improve mobility and reduce pain.

As the day progresses, pain and fatigue often intensify. Evening routines might include applying ice packs to the shoulder to reduce inflammation or using a heating pad for muscle relaxation. Gentle stretching exercises and relaxation techniques, such as meditation or deep-breathing exercises, help in winding down and managing pain.

Sleep can be particularly challenging, with finding a comfortable position being a nightly struggle. Many find relief in sleeping with a pillow under the arm to support the shoulder and reduce strain. Despite these efforts, interrupted sleep due to pain is common, leading to daytime fatigue and mood changes.

Emotional and Psychological Impact

Living with chronic pain and limitations can take an emotional toll. Feelings of frustration, anxiety, and depression are not uncommon. Maintaining a positive outlook and finding coping strategies, such as engaging in mindfulness practices, seeking counseling, or joining support groups, can be beneficial.

Osteopathic Treatment Approaches

Osteopathic Manipulative Treatment (OMT)

Osteopathic Manipulative Treatment (OMT) is a hands-on approach used by osteopathic physicians (DOs) to diagnose, treat, and prevent injuries and conditions, including supraspinatus tendonitis. OMT involves using the hands to move muscles and joints using techniques that include stretching, gentle pressure, and resistance.

• Goals of OMT: The primary objectives are to relieve pain, reduce muscle tension, improve circulation, and enhance overall body function and movement.
• Holistic Approach: OMT aims to treat the whole person, addressing not just the symptoms but also the underlying causes of the condition. This includes looking at posture, body mechanics, and other contributing factors.

Techniques and Methods Specific to Supraspinatus Tendonitis

Several OMT techniques can be specifically applied to treat supraspinatus tendonitis, each aiming to reduce inflammation, improve range of motion, and promote healing.

1. Soft Tissue Techniques: These techniques involve applying pressure to the soft tissues, such as muscles and tendons, to reduce muscle spasms, increase blood flow, and relieve pain. This can include kneading, stretching, and deep pressure techniques.
2. Muscle Energy Technique (MET): This technique uses the patient’s own muscle contractions to relax and lengthen muscles. For supraspinatus tendonitis, MET can help to reduce muscle tightness and improve shoulder mobility.
3. Counterstrain: This technique involves identifying tender points and positioning the patient in a way that reduces the tenderness. It helps to relieve pain and reduce muscle spasms.
4. High-Velocity, Low-Amplitude (HVLA) Thrusts: Although not typically applied directly to the shoulder, HVLA thrusts to the upper spine and shoulder girdle can help to improve overall mobility and function.
5. Myofascial Release: This technique focuses on releasing restrictions in the fascial tissues surrounding the muscles and tendons. It can help to reduce pain and improve movement.
6. Articulatory Techniques: Gentle, repetitive movements of the shoulder joint can help to increase range of motion and reduce stiffness.

Case Studies and Success Stories

Sharing case studies and success stories can highlight the effectiveness of OMT for treating supraspinatus tendonitis. Here are a few examples:

1. Case Study 1: A 45-year-old patient with chronic shoulder pain and limited range of motion was diagnosed with supraspinatus tendonitis. After six weeks of OMT, including soft tissue techniques and MET, the patient reported significant pain relief and improved shoulder function.
2. Case Study 2: A 30-year-old athlete with acute supraspinatus tendonitis underwent a series of OMT sessions focusing on myofascial release and counterstrain techniques. The patient experienced a reduction in inflammation and pain, allowing for a gradual return to sports activities.
3. Success Story 1: A patient with persistent shoulder pain unresponsive to conventional treatments found relief through OMT. The treatment plan included a combination of articulatory techniques and muscle energy techniques, resulting in restored shoulder mobility and decreased pain.
4. Success Story 2: An older adult with limited shoulder movement due to supraspinatus tendonitis benefited from a holistic OMT approach. The treatment addressed not only the shoulder but also postural issues and overall body mechanics, leading to improved quality of life.

These examples illustrate the potential benefits of OMT for individuals suffering from supraspinatus tendonitis. By addressing the condition holistically and using tailored techniques, osteopathic treatment can play a crucial role in the healing process.
