Ultrasound-Guided Cortisone Injections and Hyaluronic Acid Injection for Osteoarthritis of the Big Toe

 Osteoarthritis of the big toe, also known as hallux rigidus, is a common degenerative joint condition that can significantly impact daily activities, causing pain, stiffness, and difficulty walking. At Alton Pain Clinic, we specialise in advanced, minimally invasive treatments such as ultrasound-guided cortisone injections and hyaluronic acid injections to help manage this condition effectively. This comprehensive blog delves into the anatomy, pathology, symptoms, and treatments of big toe osteoarthritis, focusing on how these injections can alleviate discomfort and improve mobility.

Understanding Osteoarthritis of the Big Toe

Osteoarthritis of the big toe occurs when the cartilage covering the joint surfaces wears down over time. The condition typically affects the metatarsophalangeal (MTP) joint, which connects the big toe to the foot. The progressive loss of cartilage leads to pain, swelling, and stiffness, which can make walking and other activities challenging.

This condition often arises due to ageing, repetitive stress, or trauma to the joint. Other contributing factors may include genetic predisposition, gout, or improper footwear.

Osteoarthritis of the Big Toe

Anatomy of the Big Toe

The big toe’s MTP joint plays a crucial role in maintaining balance and supporting weight during walking and running. It comprises:

  • First Metatarsal Bone: The long bone of the foot that forms part of the MTP joint.
  • Proximal Phalanx: The bone in the big toe that articulates with the metatarsal.
  • Articular Cartilage: A smooth, cushioning tissue that covers the ends of the bones, facilitating pain-free movement.
  • Joint Capsule and Ligaments: Structures that stabilise the joint and protect it from excessive movement.

Pathology of Big Toe Osteoarthritis

The progression of osteoarthritis in the big toe involves the following changes:

  1. Cartilage Degeneration: Repeated stress or injury initiates cartilage breakdown, exposing the underlying bone.
  2. Inflammation: Damage triggers inflammation in the joint, resulting in pain and swelling.
  3. Bone Changes: Subchondral bone thickens, and osteophytes (bone spurs) may develop.
  4. Reduced Joint Space: Loss of cartilage narrows the space within the joint, limiting mobility and increasing stiffness.

Symptoms of Big Toe Osteoarthritis

Common symptoms include:

  • Pain in the big toe, particularly during movement or weight-bearing activities.
  • Swelling and tenderness around the joint.
  • Stiffness that restricts toe bending.
  • Formation of a bony bump (osteophyte) on the top of the joint.
  • Difficulty wearing certain types of shoes, especially those with narrow toe boxes.

Diagnosis of Big Toe Osteoarthritis

At Alton Pain Clinic, diagnosing osteoarthritis of the big toe involves:

  1. Medical History: Evaluating symptoms, lifestyle, and prior injuries.
  2. Physical Examination: Checking for tenderness, swelling, and range of motion.

Management of Big Toe Osteoarthritis

Although osteoarthritis cannot be cured, various treatment options can help manage symptoms and improve function:

  1. Conservative Measures:
  • Wearing comfortable, supportive footwear with a wide toe box.
  • Using orthotic inserts to redistribute pressure.
  • Avoiding high-impact activities that aggravate symptoms.

2. Minimally Invasive Treatments:

Ultrasound-Guided Cortisone Injections

Cortisone injections are widely used to manage inflammation and pain in osteoarthritis. At Alton Pain Clinic, these injections are administered with ultrasound guidance to ensure precision.

Mechanism of Action

  • Anti-Inflammatory Effects: Cortisone reduces the production of pro-inflammatory cytokines and enzymes, alleviating swelling and pain.
  • Pain Relief: By disrupting the inflammatory cycle, cortisone diminishes discomfort.
  • Improved Mobility: Less inflammation allows for greater range of motion and function.

Hyaluronic Acid Injections

Hyaluronic acid injections, also known as viscosupplementation, are another effective treatment for big toe osteoarthritis. These injections aim to restore the natural cushioning and lubrication within the joint.

Mechanism of Action

  • Enhanced Lubrication: Hyaluronic acid improves the viscoelastic properties of synovial fluid, reducing friction.
  • Cartilage Protection: Forms a protective layer over the cartilage, minimising wear.
  • Inflammation Modulation: Reduces the activity of enzymes that degrade cartilage and exacerbate inflammation.

Benefits of Ultrasound Guidance

Using ultrasound technology for cortisone and hyaluronic acid injections offers several advantages:

  • Precision: Ensures accurate placement of the injection within the joint.
  • Safety: Minimises the risk of complications or damage to surrounding tissues.
  • Enhanced Comfort: Reduces procedural pain and anxiety for patients.

  Introduction Iliopsoas tendinopathy and iliopsoas bursitis are common causes of anterior hip pain, particularly in individuals who engage in repetitive hip flexion activities such as running, cycling, or dancing. These conditions can significantly impact mobility, causing discomfort during walking, climbing stairs, or even prolonged sitting. While conservative management often includes rest, physiotherapy, and anti-inflammatory medications, some individuals may experience persistent symptoms requiring targeted interventions.  Ultrasound-guided cortisone injections are an option for managing pain and inflammation associated with iliopsoas-related conditions. This blog explores the anatomy, pathology, symptoms, diagnosis, and treatment options for iliopsoas tendinopathy and bursitis, with a focus on the role of ultrasound-guided cortisone injections.
