Carpal tunnel syndrome surgery, known as carpal tunnel release, is a procedure to relieve the pain and numbness of carpal tunnel syndrome.
The tendons that flex your fingers and the nerve that gives sensation to your thumb, index, middle, and half of your ring finger, go through a passageway in your wrist called the carpal tunnel. If you have carpal tunnel syndrome, pressure on a nerve in your wrist causes numbness and tingling in your hand. Causes include injury, health conditions like diabetes and rheumatoid arthritis, and repetitive wrist and hand movements.
During carpal tunnel surgery, surgeons cut the ligament that is roof of the carpal tunnel. This releases the pressure on the nerve and eases pain.
Carpal tunnel release is a very common outpatient procedure. Doctors consider it minor surgery. Surgeons may perform the release of carpal tunnel syndrome in a hospital or surgical center.
Carpal tunnel syndrome happens when the median nerve and tendons of the hand get squeezed inside the carpal tunnel. The carpal tunnel is a narrow passage in the wrist, covered by a thick ligament. Any amount of swelling around the carpal tunnel can pinch the nerve, causing pain, tingling, and weakness.
During carpal tunnel release, the doctor cuts through the carpal ligament. That opens up the carpal tunnel. When the ligament heals, it leaves more room for the median nerve and tendons.
Carpal tunnel release surgery can relieve symptoms of carpal tunnel syndrome or make them go away entirely.
There are several types of carpal tunnel surgery. The goal of each one is to release the carpal ligament and ease pressure on the carpal nerve. Success rates for all are high, so talk to your doctor about which may be right for you.
If you have persistent numbness, tingling, or weakness in your hand, you may benefit from carpal tunnel surgery. People with carpal tunnel syndrome often find permanent relief through the procedure.
Carpal tunnel release surgery may be right for you if:
Your doctor will try more conservative methods of treating your carpal tunnel syndrome before recommending surgery.
Many people do well with more moderate treatments, such as:
Carpal tunnel syndrome surgery is very common and very safe. However, every surgery comes with some risks.
The possible complications of carpal tunnel surgery are:
Carpal tunnel surgery is an outpatient procedure. It can happen in a hospital, surgical center, or doctor’s office. You will go home after the surgery.
Your doctor will give you specific instructions on how to get ready for your surgery.
They may ask you questions like:
Before your surgery, you may need to:
On the day of the surgery:
The procedure itself only takes about five to 15 minutes. But you may need to be at the surgical center for a few hours. You will need to get ready for the surgery and have some time to recover when it’s over.
Some patients elect to have procedural sedation through an IV. In that case, the medication is given and you would fall asleep. You can still breathe on your own and would not be placed onto the ventilator, but you would be unconscious. The surgeon then gives local anesthetic and performs the surgery.
Alternatively, patients may elect to have wide awake surgery. In that scenario, you would receive local anesthesia. That means you’ll be awake, but your wrist and hand will be numb.
Your doctor will make an incision, cut the carpal ligament, and open up the carpal tunnel. They will then stitch the incision closed and apply a bandage.
You will go home with a bandage or splint on your hand. You’ll need to wear it for about a week, keeping it clean and dry. You should avoid heavy lifting or any movement that puts strain on your hand.
You will have some discomfort as you recover. That means your body is healing. Your doctor will recommend prescription or over-the-counter (OTC) pain medicine.
After 10 to 14 days, you’ll have a follow-up visit with your doctor. They will remove the splint or bandage and make sure healing is progressing. Most patients do not require formal physical therapy.
Depending on the kind of job you have, you may have to wait several weeks to return to work. Others may return to work the day after surgery.
Your recovery time will depend on how severe your symptoms were before the surgery and how long they lasted. It can take several weeks or months for more severe symptoms to go away. But most people do see significant improvement with carpal tunnel surgery.
Most people have uncomplicated recoveries from carpal tunnel surgery.
You should call your doctor right away if you have:
