What is carpal tunnel syndrome?

Carpal tunnel syndrome is a condition where there is increased pressure on a nerve that crosses the front of your wrist (the median nerve).

The median nerve runs through a tight tunnel on the front of your wrist, together with the tendons that bend your fingers.

If the tunnel becomes too tight it can cause pressure on the nerve, usually resulting in pain or numbness in the thumb, index and middle fingers.

What are the benefits of surgery?

You should get relief from pain and numbness in your hand.

Are there any alternatives to surgery?

If your symptoms are mild, a wrist support worn at night often helps.

A steroid injection near the carpal tunnel can reduce the numbness or pain in most people but the symptoms usually come back after several weeks or months.

What does the operation involve?

The operation can usually be performed under a local anaesthetic and usually takes about 20 minutes.

Your surgeon will make a small cut on the palm of your hand. They will cut the tight ligament (the flexor retinaculum) that forms the roof of the carpal tunnel. This stops the nerve being compressed.

How soon will I recover?

You should be able to go home the same day.

Keep your hand raised and bandaged for 2 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, ask the healthcare team or your GP for advice.

Your symptoms may continue to improve for up to 6 months.

“Can not fault this hospital one bit. All of the staff were so lovely nothing was too much trouble. Very reassuring and caring which made me feel very much at ease, I didn’t want to come home! They all do such an amazing job and I’m very thankful for everything.”

Jade Baker

“Just had a total knee replacement at this fabulous hospital. From the moment you walk through the door you feel at ease. Everyone was so kind and caring. I was very nervous before my operation, but was soon assured everything would be fine. Thank you to all of you I met over my 4 day stay xx.”

Margaret Dawson

“I was very nervous and stressed before my treatment but all the staff went above and beyond to calm me down and reassure me. I was well informed and was made to feel like a person not just another number. The room I was in was spotlessly clean, not too hot and smelled fresh and not “hospitally”. The staff were very efficient and thorough.”

Leanne Helm

“I was discharged last night following an operation on my ankle. All of the staff where polite and extremely attentive. The room was cosy and clean. Every need was catered for. I was really dreading my operation the staff managed to make my stay very pleasant. Best hospital I’ve ever been in and would highly recommend to anyone. Excellent.”

Mark Goodlad
