Ultrasound-Guided Cortisone Injections and Ultrasound-Guided Hyaluronic Acid Injections for Shoulder Osteoarthritis

 

Introduction

Shoulder osteoarthritis is a degenerative joint condition that results in the progressive breakdown of cartilage within the glenohumeral joint. It can lead to pain, stiffness, and reduced mobility, affecting daily activities such as lifting, reaching, and carrying objects. While osteoarthritis of the shoulder is less common than osteoarthritis of the knee or hip, it can significantly impact quality of life.

Anatomy of the Shoulder Joint

The shoulder is a ball-and-socket joint composed of:

  • Humeral head – The ball that fits into the socket.

  • Glenoid cavity – The socket within the scapula that accommodates the humeral head.

  • Cartilage – A smooth tissue covering the joint surfaces, allowing frictionless movement.

  • Synovial membrane – A thin lining that produces synovial fluid to lubricate the joint.

  • Ligaments and tendons – Structures that provide stability and allow for coordinated movement.


Pathology of Shoulder Osteoarthritis

Osteoarthritis is characterised by:

  • Cartilage degeneration – Progressive wear and thinning of the cartilage.

  • Synovial inflammation – Irritation of the synovial membrane leading to pain and swelling.

  • Osteophyte formation – Development of bony spurs that can further restrict movement.

  • Joint space narrowing – Loss of cartilage leads to decreased space between the bones, increasing friction.

Causes and Risk Factors

Several factors contribute to the development of shoulder osteoarthritis, including:

  • Age – More common in individuals over 50.

  • Previous shoulder injury – Fractures, dislocations, or rotator cuff injuries can predispose to arthritis.

  • Repetitive use – Occupational or sports-related overuse may accelerate cartilage wear.

  • Genetics – A family history of osteoarthritis may increase susceptibility.

  • Obesity – Although not a weight-bearing joint, excess weight may contribute to systemic inflammation.

Symptoms of Shoulder Osteoarthritis

  • Gradual onset of shoulder pain, worsening over time

  • Stiffness, particularly in the morning or after periods of inactivity

  • Reduced range of motion, making overhead movements difficult

  • Crepitus (grating or clicking sound) during joint movement

  • Weakness in the affected arm due to pain and disuse

Diagnosis of Shoulder Osteoarthritis

A thorough clinical assessment is essential for diagnosis, including:

  • Patient history and symptom evaluation

  • Physical examination – Assessing pain levels, range of motion, and signs of joint instability.

Management of Shoulder Osteoarthritis

Treatment aims to alleviate pain, improve function, and slow disease progression. Management strategies include:

  • Activity modification – Avoiding movements that exacerbate pain.

  • Ultrasound-guided injections – Targeted pain relief with minimally invasive techniques.

Ultrasound-Guided Cortisone Injections for Shoulder Osteoarthritis

Corticosteroid injections are commonly used to manage shoulder osteoarthritis by reducing inflammation and alleviating pain. Ultrasound guidance ensures accurate needle placement, enhancing the effectiveness of the treatment.

Benefits of Ultrasound-Guided Cortisone Injections

  • Precise delivery – Ensures medication reaches the inflamed area.

  • Minimally invasive – Reduces the need for surgical intervention.

  • Rapid pain relief – Helps manage acute exacerbations.

  • Outpatient procedure – Quick and convenient treatment.

Mechanism of Action of Cortisone

Cortisone is a corticosteroid that acts by:

  • Reducing the production of inflammatory mediators, decreasing swelling and pain.

  • Suppressing immune responses in the joint, alleviating synovial inflammation.

  • Improving joint function by minimising discomfort associated with movement.

Ultrasound-Guided Hyaluronic Acid Injections for Shoulder Osteoarthritis

Hyaluronic acid injections, also known as viscosupplementation, involve injecting a gel-like substance into the shoulder joint to enhance lubrication and cushioning.

Benefits of Ultrasound-Guided Hyaluronic Acid Injections

  • Improved joint lubrication – Enhances synovial fluid viscosity.

  • Pain relief – Reduces friction between joint surfaces.

  • Potential cartilage protection – May help slow cartilage degradation.

  • Alternative to surgery – Provides symptomatic relief for patients unsuitable for surgery.

Mechanism of Action of Hyaluronic Acid

  • Forms a protective layer over cartilage surfaces, reducing mechanical stress.

  • Enhances the viscoelastic properties of synovial fluid, improving shock absorption.

  • May exhibit mild anti-inflammatory properties, alleviating joint pain.
