Surgery may ease symptoms right away. It will take months to fully heal.

  • Infection
  • Nerve or tendon damage

What to Expect

Prior to Procedure

Leading up to your procedure:

  • Talk to your doctor any medicines and supplements you take. You may be asked to stop taking them up to one week before surgery.
  • Arrange for a ride to and from the procedure.
  • Arrange for help at home after the procedure.
  • Do not eat or drink anything after midnight.

Anesthesia

Local or general anesthesia may be used. Local anesthesia will numb the area. With general anesthesia, you will be asleep.

Description of the Procedure

One of two methods may be used:

Open Carpal Tunnel Release

A small cut will be made in the lower palm and wrist area. The carpal ligament will be opened. This will free the median nerve. The incision will be closed with stitches and bandaged.

Endoscopic Carpal Tunnel Release

Two small cuts will be made on the palm side of the wrist. A small tool with a camera will be passed through the opening. This camera will allow the doctor to see inside of the carpal tunnel. Other tools will be passed through the other incision. These tools will be used to release the carpal ligament. All tools will be removed. The incision will be closed with stitches and bandaged.

How Much Will It Hurt?

Post-procedure Care

At the Care Center

Your wrist will be raised to control swelling. Ice packs will be used to ease swelling.

At Home

Call your doctor if you are not feeling better or you have:

  • Signs of infection, such as fever and chills
  • Redness, swelling, more pain, a lot of bleeding, or any discharge from the incision site
  • Pain that you cannot control with medicine
  • Fingers that are swollen, cold, or have changed in color
