Shoulder Pain That Won't Go Away: How Ultrasound Identifies the Cause

Shoulder pain is a common and often debilitating complaint that can significantly impact daily life. When discomfort persists despite rest and conservative measures, it signals the need for a precise diagnosis to guide effective treatment. Musculoskeletal (MSK) ultrasound offers a highly effective, non-invasive method for identifying the underlying causes of chronic shoulder pain, providing clear insights into conditions affecting the rotator cuff, bursae, and tendons.

Understanding Persistent Shoulder Pain

Persistent shoulder pain is rarely without a specific anatomical basis. The shoulder joint, a complex structure comprising bones, ligaments, tendons, and muscles, is susceptible to various injuries and degenerative changes. Common culprits behind enduring shoulder discomfort include rotator cuff tears, subacromial bursitis, and tendinopathies. Impingement syndrome, a condition where tendons or bursae are compressed, also frequently contributes to chronic pain.

Rotator Cuff Tears

The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint, providing stability and enabling a wide range of motion. Tears can range from partial to full-thickness and are often the result of acute injury or chronic degeneration. An ultrasound scan can accurately visualise the integrity of these tendons, detecting tears and assessing their size and location, which is crucial for determining the appropriate management strategy.

Subacromial Bursitis

The subacromial bursa is a fluid-filled sac located between the rotator cuff tendons and the acromion bone. Its function is to reduce friction during shoulder movement. Inflammation of this bursa, known as bursitis, can cause significant pain, particularly when lifting the arm. Ultrasound is highly sensitive in detecting fluid accumulation and thickening within the bursa, confirming the diagnosis of bursitis.

Tendinopathy

This term encompasses conditions affecting the tendons, such as tendinitis (inflammation) and tendinosis (degeneration). The rotator cuff tendons, particularly the supraspinatus, are frequently affected. Ultrasound can identify changes in tendon structure, such as thickening, calcification, or areas of degeneration, which are indicative of tendinopathy. This detailed visualisation helps differentiate between inflammatory and degenerative processes.

Impingement Syndrome

This occurs when the rotator cuff tendons or the subacromial bursa are compressed as they pass through the subacromial space. While often a clinical diagnosis, ultrasound can provide objective evidence by demonstrating bursal thickening, rotator cuff tendinopathy, or dynamic impingement during specific movements. This dynamic assessment is a key advantage of ultrasound over static imaging modalities.

The Role of MSK Ultrasound in Diagnosis

MSK ultrasound has emerged as a frontline diagnostic tool for shoulder pathologies due to its numerous benefits. It is a dynamic imaging modality, meaning it allows for real-time assessment of structures during movement, which can reveal issues not apparent on static scans. This is particularly valuable for conditions like impingement syndrome, where pain is often exacerbated by specific actions.

Furthermore, ultrasound is non-ionising, making it a safe option for repeated examinations without radiation exposure. It is also highly accessible and cost-effective compared to MRI. At London Ultrasound, located at 29 Weymouth Street in Marylebone, Central London, our HCPC registered sonographers utilise state-of-the-art equipment to provide comprehensive and accurate shoulder assessments.

During an MSK shoulder ultrasound, the sonographer will systematically examine all relevant structures, including the rotator cuff tendons (supraspinatus, infraspinatus, subscapularis, and teres minor), the long head of biceps tendon, the subacromial-subdeltoid bursa, the acromioclavicular (AC) joint, and surrounding muscles. The patient will be asked to perform various movements to assess for dynamic impingement or pain provocation, allowing for a thorough functional evaluation.

Advantages of Ultrasound-Guided Injections

Beyond diagnosis, ultrasound plays a crucial role in guiding therapeutic interventions, such as corticosteroid injections. For conditions like severe bursitis or tendinopathy, an ultrasound-guided injection can deliver anti-inflammatory medication directly to the affected area with precision. This ensures optimal drug placement, maximises therapeutic effect, and minimises the risk of complications associated with blind injections.

At London Ultrasound, our specialists are proficient in performing ultrasound-guided shoulder injections, offering a targeted approach to pain relief. This precision is particularly beneficial for deep or small structures, where accurate needle placement is paramount for successful outcomes. Patients can often experience significant relief following these targeted injections, facilitating rehabilitation and recovery.
