Cubital tunnel syndrome is a condition that affects the ulnar nerve, one of the main nerves supplying the hand and forearm. The nerve travels through a narrow passage on the inside of the elbow, known as the cubital tunnel.
When the nerve becomes compressed or stretched, it cannot send signals normally. This can lead to changes in sensation, weakness and difficulty using your hand.
Cubital tunnel syndrome is the second most common nerve compression condition in the upper limb after carpal tunnel syndrome.
Cubital tunnel syndrome symptoms often develop gradually and may come and go at first. As pressure on the ulnar nerve increases, symptoms may become more frequent or persistent.
You may experience:
Cubital tunnel syndrome develops when pressure is placed on the ulnar nerve or when the nerve is repeatedly stretched.
Common causes and risk factors include:
Your consultant will review your symptoms, medical history and daily activities to help understand what may be contributing to your symptoms.
Diagnosis begins with a detailed consultation and examination by your specialist.
Your assessment may include:
If further information is needed, your consultant may recommend additional tests, including:
Different people require different tests, and your diagnostic pathway will be tailored to your symptoms and examination findings.
Treatment depends on your symptoms, how long they have been present and whether there are signs of nerve damage. Many people improve with nonsurgical treatment, especially when symptoms are mild or found early.
For many people, symptoms can improve without surgery.
Your treatment plan may include:
Activity modification
Avoiding activities that place prolonged pressure on the elbow or require repeated bending may help reduce irritation of the nerve.
Splinting
Wearing a splint at night can help keep the elbow in a straighter position while you sleep, reducing pressure on the ulnar nerve.
Medication
Pain-relieving or anti-inflammatory medicines may help manage discomfort, if appropriate.
Physiotherapy
Exercises and nerve gliding techniques may help improve movement and reduce irritation of the nerve. Your physiotherapist can also advise on posture and activity changes that may help prevent symptoms from returning.
Surgery
If symptoms are severe, continue to worsen, or there are signs of significant nerve damage, surgery may be recommended to relieve pressure on the ulnar nerve. Your consultant will discuss whether this is the most appropriate option for you.
