Ultrasound-Guided Cortisone and Hyaluronic Acid Injections for Wrist Osteoarthritis

 

Introduction

The wrist is a highly complex joint that allows fine hand movements essential for daily tasks such as gripping, writing, and lifting. When osteoarthritis develops in the wrist, it can interfere significantly with mobility and quality of life. Wrist osteoarthritis is a progressive condition where the cartilage cushioning the bones gradually wears away, leading to stiffness, swelling, and discomfort.

At Joint Injections, clinicians provide ultrasound-guided cortisone and hyaluronic acid injections as part of a management plan for wrist osteoarthritis. These approaches are designed to assist in relieving discomfort, improving joint mobility, and allowing patients to return to their routine activities with greater ease.

Anatomy of the Wrist

The wrist joint, medically known as the radiocarpal joint, is composed of several small bones, ligaments, tendons, and cartilage structures that work together to maintain mobility and stability.

  • Bones: The wrist contains eight carpal bones, along with the radius and ulna of the forearm.
  • Cartilage: A smooth cartilage layer covers the bone ends, allowing frictionless movement.
  • Ligaments: Numerous ligaments stabilise the wrist, preventing dislocation and guiding joint motion.
  • Tendons: Tendons from muscles in the forearm extend into the hand, enabling gripping and fine motor control.

The intricate structure of the wrist makes it susceptible to degeneration, particularly where cartilage is involved.

Pathology of Wrist Osteoarthritis

Wrist osteoarthritis occurs when the protective cartilage that lines the joint surfaces deteriorates over time. This degeneration can lead to bone-on-bone contact, triggering inflammation, stiffness, and restricted function.

The condition may arise as:

  • Primary osteoarthritis: Due to natural wear and tear over time.
  • Secondary osteoarthritis: Following trauma, fractures, or ligament injury in the wrist.

With progression, the wrist may show:

  • Reduced range of movement.
  • Increased joint stiffness, especially in the morning or after inactivity.
  • Episodes of swelling due to inflammation.
  • Deformity in severe cases.

Causes of Wrist Osteoarthritis

Several factors contribute to the development of wrist osteoarthritis:

  • Ageing: Natural wear and tear of cartilage over time.
  • Previous injuries: Fractures or ligament damage accelerating cartilage breakdown.
  • Repetitive stress: Occupational or lifestyle activities placing strain on the wrist joint.
  • Genetic predisposition: Family history of arthritis may increase susceptibility.
  • Inflammatory joint conditions: Pre-existing conditions may predispose to degeneration.

Symptoms of Wrist Osteoarthritis

Patients with wrist osteoarthritis often report:

  • Persistent discomfort in the wrist joint.
  • Stiffness and reduced flexibility.
  • Swelling and tenderness on movement.
  • Weak grip strength and difficulty with tasks such as opening jars.
  • Clicking or grinding sensations (crepitus) during movement.

Diagnosis of Wrist Osteoarthritis

Clinicians may diagnose wrist osteoarthritis through a combination of clinical examination and imaging studies.

  • Clinical assessment: A detailed history of symptoms, lifestyle factors, and previous injuries.
  • Physical examination: Assessing for swelling, tenderness, range of motion, and grip strength.
  • Imaging: Ultrasound imaging is valuable for guiding injections precisely into the affected joint.

Management of Wrist Osteoarthritis

Management of wrist osteoarthritis focuses on alleviating discomfort, maintaining joint mobility, and supporting functional use of the hand. Options may include:

  • Activity modification: Avoiding repetitive stress movements.
  • Splinting or bracing: To stabilise and support the joint.
  • Analgesic and anti-inflammatory medications: For temporary relief.
  • Injection therapies: Cortisone and hyaluronic acid administered under ultrasound guidance.

Role of Ultrasound Guidance

At Joint Injections, ultrasound guidance plays a crucial role in ensuring the accuracy and safety of injection therapies. By visualising the joint in real time, clinicians can direct the needle to the exact location of inflammation or degeneration, increasing precision and reducing the risk of complications.

Cortisone Injections for Wrist Osteoarthritis

Cortisone, a corticosteroid, is commonly used to manage inflammation within the joint. When injected into the wrist, it can help reduce swelling and stiffness, providing an opportunity for improved mobility.

Mechanism of Action of Cortisone

  • Cortisone works by mimicking the body’s natural hormones that regulate inflammation.
  • It decreases the activity of inflammatory cells in the joint.
  • This reduces swelling and irritation in the synovial lining of the wrist.
  • By dampening the inflammatory response, cortisone can provide relief from discomfort and stiffness.

Hyaluronic Acid Injections for Wrist Osteoarthritis

Hyaluronic acid is a naturally occurring substance in joint fluid that helps lubricate and cushion the joint. In osteoarthritis, the quality and quantity of natural hyaluronic acid are reduced.

Mechanism of Action of Hyaluronic Acid

  • When injected, hyaluronic acid supplements the joint fluid.
  • It improves lubrication between the joint surfaces, reducing friction.
  • It may assist in cushioning the bones during movement.
  • The injection can help support smoother motion and reduce mechanical stress on the joint.

Benefits of Ultrasound-Guided Injections

Ultrasound-guided cortisone and hyaluronic acid injections at Joint Injections offer several potential advantages:

  • Precision: Targeting the exact area of concern within the wrist.
  • Reduced risk: Avoiding surrounding structures such as tendons and ligaments.
  • Comfort: Providing more accurate and potentially less painful procedures.
  • Efficiency: Same-day diagnosis and treatment in many cases.

  Introduction Baxter’s Nerve Entrapment , also known as inferior calcaneal nerve entrapment, is a condition that can contribute to chronic heel pain. It is often misdiagnosed as plantar fasciitis due to the overlap in symptoms. The condition arises when the first branch of the lateral plantar nerve, known as Baxter’s nerve, becomes compressed or irritated. Anatomy of Baxter’s Nerve Baxter’s nerve is a branch of the lateral plantar nerve, which originates from the tibial nerve. This small but significant nerve travels along the medial aspect of the heel and innervates the abductor digiti minimi muscle of the foot. Due to its anatomical course, Baxter’s nerve is prone to compression between the deep fascia of the abductor hallucis muscle and the medial calcaneal tuberosity.
