Ulnar Decompression Surgery & Ulnar Nerve Surgery – Understanding Treatment, Recovery and Benefits

rs, especially when bending your elbow, you might be suffering from ulnar nerve compression. This common condition, often referred to as cubital tunnel syndrome, can greatly affect daily function and quality of life. Fortunately, procedures like ulnar decompression surgery or ulnar nerve surgery offer effective relief.

In this blog, we'll explore what these procedures involve, who may need them, and what you can expect in terms of recovery and outcomes.

What is the Ulnar Nerve?

The ulnar nerve runs from your neck through the shoulder, down the arm, and passes through a narrow tunnel at the elbow called the cubital tunnel. It provides sensation to the ring and little fingers and powers many of the small muscles in the hand that help with fine motor skills.

Compression of this nerve—especially at the elbow—can cause symptoms like:

• Numbness and tingling in the ring and little fingers
• Weak grip strength
• Hand clumsiness or muscle wasting in severe cases
• Pain at the inside of the elbow or forearm

When these symptoms persist or worsen despite non-surgical treatments such as bracing, activity modification, or physiotherapy, ulnar nerve surgery may be necessary.

What is Ulnar Decompression Surgery?

Ulnar decompression surgery is designed to relieve pressure on the ulnar nerve. There are several surgical techniques, and the most appropriate one depends on the severity and cause of your nerve compression.

The most common types include:

1. Simple Decompression

This involves releasing the ligament or tissue that is putting pressure on the ulnar nerve in the cubital tunnel. It is usually performed under local or general anaesthesia and involves a small incision around the elbow.

2. Ulnar Nerve Transposition

If the nerve is unstable or at risk of getting compressed again in its original location, the surgeon may move (transpose) the nerve to a safer position in front of the elbow. This prevents the nerve from being stretched during elbow movement.

3. Medial Epicondylectomy

In certain cases, a part of the bone called the medial epicondyle may be removed to make more space for the nerve. This is less common but can be effective for patients with structural abnormalities.

Who Needs Ulnar Nerve Surgery?

You may be a candidate for ulnar nerve decompression surgery if:

• Non-surgical treatments have failed after several weeks or months
• You experience muscle weakness or wasting in the hand
• Symptoms significantly affect daily tasks or quality of life
• There's evidence of nerve damage on tests like an EMG (electromyography)

What to Expect from the Surgery

Procedure Time: 30–90 minutes

Anaesthesia: Local, regional, or general, depending on the method and patient preference

Hospital Stay: Usually outpatient – go home the same day

Post-surgery, your arm may be in a bandage or splint for a short period. You’ll be encouraged to start gentle movements within days unless otherwise advised. Stitches are removed in 10–14 days.

Recovery After Ulnar Nerve Surgery

Recovery varies based on the procedure and severity of nerve damage before surgery:

• Mild cases often improve within a few weeks
• Moderate to severe cases may take several months
• Physical therapy helps restore strength and flexibility
• Return to desk work: Often in 1–2 weeks
• Manual work or sports: May require 6–12 weeks

It's important to follow post-operative instructions carefully, including avoiding prolonged elbow flexion and heavy lifting in the early weeks.

Success Rate and Long-Term Outlook

The majority of patients experience significant symptom relief after ulnar nerve surgery, especially when done before permanent nerve damage sets in.

• Studies show success rates of 80–90%
• Earlier intervention generally leads to better outcomes
• Some residual numbness may persist in long-standing cases
• Recurrent compression is rare but possible

Choosing the Right Specialist

For optimal results, it’s crucial to consult a surgeon experienced in upper limb and nerve conditions. In London, specialists like Mr Jagwant Singh, a leading shoulder and elbow surgeon, offer expert evaluation and advanced surgical techniques tailored to each patient’s needs.

Conclusion

If numbness, tingling, or hand weakness is interfering with your daily life, ulnar decompression surgery may be the key to relief. With modern surgical techniques and proper aftercare, patients can regain hand function, reduce discomfort, and return to their regular activities.

Don’t ignore persistent symptoms—early treatment of ulnar nerve compression can prevent long-term damage and improve your quality of life. If you're in the UK and seeking expert advice, consider booking a consultation with a trusted orthopaedic or elbow surgeon in London.
