What is ulnar nerve compression?
The ulnar nerve goes round the back of the inner side of your elbow and through a tight tunnel between the forearm muscles. Ulnar nerve compression happens when there is increased pressure on the ulnar nerve, usually resulting in numbness in your ring and little fingers.
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 an operation to release the nerve to prevent permanent nerve damage.
What does the operation involve?
Your surgeon will make a cut over the back of the inner side of your elbow. 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.
The operation usually takes between half an hour and three-quarters of an hour. A variety of anaesthetic techniques is possible.
