Ultrasound-Guided Cortisone Injections for Cubital Tunnel Syndrome at Alton Pain Clinic

Introduction

Cubital Tunnel Syndrome is a condition that affects the ulnar nerve as it passes through a narrow tunnel of tissue on the inner side of the elbow. This nerve plays a vital role in sensation and movement in the forearm, hand, and fingers, particularly the ring and little fingers. When compressed or irritated, the ulnar nerve can give rise to discomfort, tingling, weakness, or pain in these areas.

At Alton Pain Clinic, clinicians use a patient-centred approach, supported by imaging techniques such as ultrasound, to deliver precision-based treatments such as cortisone injections. This blog provides a detailed overview of Cubital Tunnel Syndrome, its anatomy, pathology, symptoms, diagnosis, and the role of ultrasound-guided cortisone injections.

Anatomy of the Cubital Tunnel

The cubital tunnel is a narrow space located on the inner aspect of the elbow. It is bordered by the bony prominence of the medial epicondyle of the humerus, the olecranon process of the ulna, and a fibrous band of tissue called Osborne’s ligament. The ulnar nerve travels through this space, making it vulnerable to compression.

The ulnar nerve originates from the brachial plexus in the neck, travels down the inner arm, and supplies sensation to the little finger and part of the ring finger. It also controls several muscles in the forearm and hand, especially those involved in fine motor control.

Because the cubital tunnel is relatively narrow and rigid, any swelling, thickening of surrounding tissue, or repeated bending of the elbow can contribute to pressure on the ulnar nerve.

Pathology of Cubital Tunnel Syndrome

Cubital Tunnel Syndrome occurs when the ulnar nerve becomes compressed within its passage. This compression can lead to disturbances in both sensory and motor function.

Factors that may contribute include:

• Prolonged elbow flexion — sustained bending during activities such as phone use, desk work, or sleeping positions.
• Direct pressure — leaning on the elbow for extended periods.
• Repetitive strain — repetitive bending and straightening of the elbow.
• Anatomical changes — narrowing of the cubital tunnel due to arthritis, injury, or thickened connective tissue.

Over time, ongoing compression can cause nerve irritation, leading to symptoms ranging from mild tingling to muscle weakness and reduced grip strength.

Symptoms

The symptoms of Cubital Tunnel Syndrome can vary in severity and may include:

• Tingling or “pins and needles” in the little finger and part of the ring finger.
• Numbness in the same distribution.
• Pain along the inner side of the elbow and forearm.
• Weakness in hand muscles, particularly affecting grip and finger coordination.
• Difficulty performing tasks requiring fine motor control.

Symptoms are often worse at night or during activities involving sustained elbow flexion.

Diagnosis

Diagnosis is made through a detailed clinical assessment, which may involve:

• History-taking — discussing onset, pattern, and aggravating factors of symptoms.
• Physical examination — including specific nerve tests such as Tinel’s sign over the cubital tunnel.
• Imaging — ultrasound may be used to visualise the ulnar nerve, detect swelling, or identify changes in surrounding tissues.

At Alton Pain Clinic, clinicians utilise ultrasound imaging as part of the diagnostic and treatment process to provide accuracy and precision in management.

Management Approaches

Treatment for Cubital Tunnel Syndrome may involve:

• Activity modification — avoiding prolonged elbow flexion or leaning on elbows.
• Injections — ultrasound-guided cortisone injections may be offered to reduce local inflammation around the nerve.

Ultrasound-Guided Cortisone Injections

Ultrasound-guided cortisone injections are a non-surgical option that may be considered for the management of Cubital Tunnel Syndrome. Ultrasound enables clinicians to directly visualise the ulnar nerve and surrounding structures, ensuring precise delivery of cortisone to the affected area.

At Alton Pain Clinic, ultrasound guidance is integrated into the process to optimise accuracy, reduce risks, and allow real-time monitoring throughout the procedure.

Mechanism of Action of Cortisone

Cortisone is a type of corticosteroid that mimics naturally occurring hormones in the body. Its effects are primarily anti-inflammatory.

When cortisone is injected into the region surrounding the compressed ulnar nerve, it:

• Reduces local inflammation in tissues surrounding the nerve.
• Minimises swelling within the cubital tunnel.
• Decreases pressure on the ulnar nerve.
• Creates an environment in which normal nerve function may be supported.

By targeting inflammation at the source, cortisone injections may contribute to a reduction in irritation and discomfort.

Benefits of Ultrasound Guidance at Alton Pain Clinic

The use of ultrasound-guided injections at Alton Pain Clinic provides several advantages:

• Direct visualisation of the nerve and nearby structures.
• Precise delivery of cortisone into the targeted area.
• Minimised risk of injection into unintended tissues.
• Real-time monitoring during the procedure.

These features enable clinicians at Alton Pain Clinic to tailor treatment with attention to detail and accuracy.
