Ultrasound-Guided Cortisone Injections for Calcific Tendinopathy

Introduction Calcific tendinopathy is a painful condition characterised by the deposition of calcium crystals within a tendon, most commonly in the rotator cuff of the shoulder. This condition can significantly impact daily activities, causing discomfort and limiting mobility. Despite its prevalence, the exact cause of calcific tendinopathy remains unclear, though it is thought to result from a combination of mechanical stress, degeneration, and metabolic changes in the tendons.

At Alton Pain Clinic, we specialise in minimally invasive solutions for musculoskeletal conditions, including **ultrasound-guided cortisone injections**. This advanced technique is tailored to manage the pain and inflammation associated with calcific tendinopathy, offering patients a targeted and precise treatment option. In this comprehensive blog, we explore the condition in detail and discuss the benefits of ultrasound-guided cortisone injections as part of a multidisciplinary treatment approach.

Anatomy of Tendons Tendons are strong, fibrous tissues that connect muscles to bones, transmitting forces to enable movement. They consist of:

• Collagen Fibres: Primarily type I collagen, which provides tensile strength.
• Extracellular Matrix: Includes proteoglycans and water, contributing to tendon elasticity and resilience.
• Cells: Tendon fibroblasts (tenocytes) maintain the extracellular matrix.
• Blood Supply: Tendons have a limited vascular supply, particularly in areas prone to injury.

The rotator cuff, where calcific tendinopathy is most commonly observed, includes four tendons: supraspinatus, infraspinatus, teres minor, and subscapularis. These tendons stabilise the shoulder joint and facilitate arm movements such as lifting and rotation.

What Is Calcific Tendinopathy? Calcific tendinopathy occurs when calcium deposits form within the tendons. It predominantly affects the rotator cuff, especially the supraspinatus tendon. The condition progresses through three stages:

1. Pre-Calcific Stage: Cellular changes in the tendon predispose it to calcium deposition.
2. Calcific Stage:

• Formative Phase: Calcium crystals are deposited, and the area may enlarge.
• Resorptive Phase: The body attempts to reabsorb the deposits, leading to inflammation and significant pain.

3. Post-Calcific Stage: Healing occurs, with the tendon returning to its normal structure and function.

Causes of Calcific Tendinopathy The exact cause remains uncertain, but several factors are thought to contribute:

• Degenerative Changes: Age-related wear and tear weaken the tendon, making it more susceptible.
• Mechanical Stress: Repetitive or excessive use of the tendon can lead to microtrauma and calcium deposition.
• Genetic Predisposition: Some individuals may have an increased likelihood of developing the condition.
• Metabolic Factors: Conditions such as diabetes and thyroid disorders have been linked to calcific tendinopathy.

Symptoms of Calcific Tendinopathy Symptoms vary depending on the stage of the condition but typically include:

• Shoulder Pain: Localised pain that may radiate down the arm, worsening at night or with overhead activities.
• Stiffness: Reduced range of motion in the shoulder, particularly during abduction or rotation.
• Swelling: Localised tenderness and inflammation in the affected area.
• Weakness: Difficulty lifting objects or performing routine tasks.
• Episodes of Severe Pain: Often during the resorptive phase when the body attempts to break down the calcium deposits.

Diagnosis of Calcific Tendinopathy A comprehensive evaluation is essential for an accurate diagnosis. At Alton Pain Clinic, we utilise a combination of clinical assessments and imaging techniques:

• Physical Examination: Assessment of pain, tenderness, and range of motion.
• Special Tests: Impingement tests may help localise the pain to the rotator cuff.
• Imaging:
• X-rays: Detect calcium deposits in the tendon.
• Ultrasound: Visualises the size, location, and density of the calcium deposits.
• MRI: Assesses the surrounding soft tissues and tendon integrity.

Management of Calcific Tendinopathy Treatment depends on the severity of symptoms and the stage of the condition. Options include:

1. Conservative Management:

• Rest and activity modification.
• Application of ice packs to reduce inflammation.
• Physiotherapy to improve strength and flexibility.

2. Medications:

• Non-steroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation.

3. Minimally Invasive Interventions:

• Ultrasound-Guided Cortisone Injections: To reduce inflammation and alleviate pain.
• Barbotage: Ultrasound-guided needling to break down and remove calcium deposits.

Ultrasound-Guided Cortisone Injections Cortisone injections are a cornerstone of treatment for managing inflammation and pain associated with calcific tendinopathy. At Alton Pain Clinic, we use ultrasound guidance to ensure precise placement of the injection directly into the affected tendon or surrounding structures.

Mechanism of Action of Cortisone Cortisone, a corticosteroid, is a synthetic analogue of cortisol, a hormone naturally produced by the adrenal glands. Its therapeutic effects include:

• Inhibition of Inflammatory Mediators: Suppresses prostaglandins and cytokines, reducing inflammation at the cellular level.
• Stabilisation of Cell Membranes: Prevents the release of enzymes that exacerbate inflammation.
• Reduction in Vascular Permeability: Decreases swelling and fluid accumulation around the tendon.
• Pain Modulation: Addresses pain by mitigating the inflammatory response.

The use of ultrasound ensures the medication is accurately delivered, enhancing its effectiveness and minimising the risk of complications.

Benefits of Ultrasound-Guided Cortisone Injections

• Precision: Real-time imaging allows for accurate targeting of the calcium deposits or surrounding inflamed tissue.
• Minimally Invasive: The procedure involves minimal discomfort and no significant downtime.
• Quick Relief: Many patients experience symptom improvement within a few days.
