Carpal Tunnel Surgery
WHAT YOU NEED TO KNOW:
What do I need to know about carpal tunnel surgery?
Carpal tunnel surgery, or decompression, is used to take pressure off the median nerve in your wrist. The median nerve controls muscles and feeling in the hand. Surgery may be done through an opening on your palm. This is called open surgery. Your surgeon may instead put a scope and tools into 1 or 2 small incisions on your wrist or palm. This is called endoscopic surgery.
How do I prepare for surgery?
Your healthcare provider will tell you how to prepare for surgery. He may tell you not to eat or drink anything after midnight on the day of your surgery. He will tell you which medicines to take or not take on the day of surgery. Arrange to have someone drive you home after surgery. You may get antibiotics before surgery to prevent an infection. Tell your healthcare provider if you have ever had an allergic reaction to antibiotics.
What will happen during surgery?
- You may be given local or regional anesthesia to help prevent pain during surgery. Local anesthesia will make only your wrist numb. Regional anesthesia will make your wrist, hand, and arm numb. You may instead be given general anesthesia to keep you asleep and free from pain. You may need this anesthesia if your surgeon thinks surgery will take a long time or involve a large part of your wrist.
- For open surgery, your surgeon will make an incision on the palm of your hand. The incision may extend to your wrist. A ligament will be cut to release the pressure on the nerve. This ligament is a band of tissue that connects joints in your wrist. Your surgeon may also remove scar tissue or anything else that may be pressing on the nerve.
- For endoscopic surgery, your surgeon will make 1 or 2 incisions on your wrist or palm. He will insert the endoscope with the camera through an incision to help guide him during surgery. Tools may be put in your wrist to help protect the nerves. He will then cut the ligament that is pressing on the nerve.
- The incision will be closed with stitches and covered with bandages.
What will happen after surgery?
A splint may be placed on your wrist to keep it from moving. You will be taken to a room where you will rest until you are fully awake and gain feeling in your arm. Your healthcare provider may ask you to move your fingers soon after your surgery. Do not try to get out of bed until your healthcare provider says it is okay.
What are the risks of carpal tunnel surgery?
You may bleed more than expected or get an infection. Your skin may bruise. A thick, painful scar may form where you had surgery. You may develop trigger finger (fingers locked in a bent position). Surgery may cause long-term numbness or weakness in your fingers, hand, or wrist. Your symptoms may not go away, and you may need surgery again.
