The ulnar nerve goes round the back of the inner side of your elbow (sometimes called your ‘funny bone’). It then goes through a tight tunnel between the forearm muscles (see figure 1).
What will happen during my ulnar nerve release?
When you meet with your consultant surgeon they'll ensure that you have the opportunity to ask any questions you may have about your ulnar nerve release, they'll discuss with you what'll happen before, during and after the procedure and any pain you might have. Take this time with your consultant surgeon to ensure your mind is put at rest. We know that having an operation of any type can be stressful so we've created a short downloadable guide that you might find useful to print off and use to write down any questions you may have. Do take this with you to your consultation.
Ulnar nerve compression (also called cubital tunnel syndrome) is a condition where there is increased pressure on the ulnar nerve, usually resulting in numbness in your ring and little fingers. Ulnar nerve release surgery aims to resolve this.
What are the benefits of surgery?
Ulnar nerve release surgery helps to prevent further damage to the nerve. If you have the operation early enough, the numbness in your hand may get better.
Are there any alternatives to surgery?
If your symptoms are mild and happen mostly at night, a splint to hold your elbow straight while you are in bed often helps.
In many cases, it is best to have ulnar nerve release surgery to release the nerve to prevent permanent nerve damage.
What does the operation involve?
A variety of anaesthetic techniques are possible. The operation usually takes between half an hour and three-quarters of an hour.
Your surgeon will make a cut over the back of your elbow on the inner side. They will cut any tight tissue that is compressing the nerve.
Sometimes your surgeon will need to remove a piece of bone, or move the nerve so that it lies in front of the elbow.
What complications can happen?

How soon will I recover?

You should keep your arm lifted up for the first couple of days. It is important to gently exercise your fingers, elbow and shoulder to prevent stiffness.
Regular exercise should help you to return to normal activities as soon as possible. Before you start exercising, you should ask a member of the healthcare team or your GP for advice.
Your symptoms may continue to improve for up to six months.

Paying for your procedure
Ulnar nerve release surgery costs are covered by most medical insurance policies, but please check with your insurer first. If you are paying for your own procedure the cost will be explained and confirmed in writing when you book the procedure. Ask the hospital for a quote beforehand, and ensure that this includes the surgeon’s fee, the anaesthetist’s fee and the hospital charge for your procedure.
