Ultrasound-Guided Cortisone Injections for Distal Biceps Tendon

 

Ultrasound-Guided Cortisone Injections for Distal Biceps Tendon

At Alton Pain Clinic, we focus on providing advanced, minimally invasive treatments to manage musculoskeletal pain effectively. The distal biceps tendon, a critical structure for arm movement and strength, is susceptible to injury, inflammation, and degeneration, leading to significant functional limitations. This blog explores everything you need to know about the distal biceps tendon, the benefits of ultrasound-guided cortisone injections, and how this targeted treatment can provide relief.

Understanding the Distal Biceps Tendon

Introduction

The distal biceps tendon connects the biceps brachii muscle to the forearm’s radial tuberosity. It enables essential movements such as flexing the elbow and rotating the forearm. Injuries to this tendon are often associated with activities requiring repetitive lifting or sudden traumatic events, making it a common issue among athletes, manual labourers, and older adults.

Distal Biceps Tendon Pain

Detailed Anatomy of the Distal Biceps Tendon

The biceps brachii muscle, located in the front of the upper arm, has two heads:

  • Long Head: Originates from the supraglenoid tubercle of the scapula.
  • Short Head: Originates from the coracoid process of the scapula.

Both heads converge into a single tendon near the elbow, forming the distal biceps tendon, which inserts onto the radial tuberosity. This robust tendon facilitates:

  • Flexion of the Elbow: Bringing the forearm closer to the upper arm.
  • Forearm Supination: Rotating the palm upwards, crucial for activities like turning keys or using tools.

The bicipital aponeurosis, a fibrous extension, also supports the tendon by distributing force across the forearm muscles.

Pathology of the Distal Biceps Tendon

Tendinitis

Tendinitis refers to inflammation of the tendon due to overuse or repetitive strain. It is common in individuals performing repetitive pulling or lifting activities.

Symptoms:

  • Pain and tenderness at the front of the elbow.
  • Swelling and stiffness, particularly after activity.
  • Weakness in elbow flexion or forearm supination.

Tendinopathy

Tendinopathy involves chronic degeneration of the tendon, often due to prolonged overuse or insufficient healing from microtrauma. It can weaken the tendon, increasing the risk of tears.

Symptoms:

  • Persistent discomfort.
  • Gradual decline in arm strength.
  • Thickening or irregularity in the tendon structure (visible on imaging).

Partial Tears

Partial tears occur when the tendon fibres are damaged but not completely severed. These are often associated with:

  • Acute trauma, such as lifting a heavy object suddenly.
  • Progressive degeneration due to untreated tendinopathy.

Symptoms:

  • Sharp pain at the time of injury.
  • Localised swelling and bruising.
  • Reduced range of motion and function.

Complete Ruptures

A complete rupture involves full detachment of the distal biceps tendon from its insertion on the radial tuberosity. This severe condition often requires surgical repair.

Symptoms:

  • Sudden, intense pain followed by weakness.
  • Visible deformity in the arm (“Popeye deformity”).
  • Inability to perform movements requiring elbow flexion or supination.

Causes and Risk Factors for Distal Biceps Tendon Injuries

Overuse

Frequent and repetitive movements, such as heavy lifting or throwing, strain the tendon over time.

Trauma

Sudden high-impact forces, like catching a falling object, can damage the tendon.

Age and Degeneration

Tendon elasticity and strength naturally decline with age, making older individuals more prone to injuries.

Underlying Medical Conditions

Conditions like diabetes, inflammatory arthritis, and metabolic disorders can weaken the tendon.

Inadequate Warm-Up

Performing strenuous activities without proper preparation increases the risk of injury.

Diagnosing Distal Biceps Tendon Conditions

Clinical Examination

A thorough examination focuses on:

  • Pain and tenderness near the elbow.
  • Weakness during resisted elbow flexion or forearm supination.
  • Abnormal movement patterns or deformities.

Imaging Modalities

  1. Ultrasound:
  • Dynamic imaging of the tendon in real time.
  • Detection of inflammation, partial tears, or thickening.
  • Non-invasive and highly effective for initial evaluation.

2. MRI:

  • Detailed assessment of soft tissue structures.
  • Often used in complex cases or suspected ruptures.

Management of Distal Biceps Tendon Injuries

Conservative Treatments

  • Rest: Avoiding activities that strain the tendon.
  • Ice Therapy: Reduces swelling and pain.
  • NSAIDs: Relieves pain and inflammation.

Ultrasound-Guided Cortisone Injections

For persistent inflammation or pain, ultrasound-guided cortisone injections provide a precise and effective treatment option.

Why Ultrasound Guidance?

  • Allows for targeted delivery of cortisone to the inflamed tendon.
  • Minimises the risk of affecting adjacent structures like nerves or blood vessels.
  • Enhances patient safety and comfort during the procedure.

How Cortisone Helps with Distal Biceps Tendon Conditions

Cortisone is a corticosteroid with potent anti-inflammatory properties.

Mechanism of Action

  1. Reduction of Inflammatory Response: Cortisone suppresses pro-inflammatory mediators like cytokines and enzymes, reducing swelling and tissue irritation.
  2. Pain Relief: Lowered inflammation alleviates pressure on the tendon, decreasing discomfort.
  3. Enhanced Recovery: Cortisone facilitates the restoration of normal function by reducing inflammation-induced tissue damage.

Post-Injection Rehabilitation

To maximise the benefits of cortisone injections:

  • Immediate Rest: Avoid strenuous activity for 24–48 hours.
  • Gradual Reintroduction of Movement: Under physiotherapist guidance.
  • Strengthening Exercises: Focus on rebuilding arm and forearm strength.
