Carpal tunnel release is surgery that reduces the pressure on a nerve in the wrist. Your doctor will cut a ligament that presses on the nerve. This lets the nerve pass freely through the tunnel without being squeezed.
The surgery can be open or endoscopic. In open surgery, your doctor makes a small cut in the palm of your hand. This cut is called an incision. In endoscopic surgery, your doctor makes one small incision in the wrist, or one small incision in the wrist and one in the palm. Your doctor puts a lighted tube into the incision. The tube is called an endoscope, or scope. Surgical tools are put in along with the endoscope.
In both types of surgeries, the incisions are closed with stitches. The incisions leave scars that usually fade in time.
You may be asleep during the surgery. Or you may be awake and have medicine to numb your hand and arm so you will not feel pain.
After surgery, your wrist and hand pain should begin to go away. It usually takes 3 to 4 months to recover and 1 year before your hand strength returns. How much hand strength returns is different for each person.
You will go home the same day as the surgery. When you can return to work depends on the type of work you do.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
What happens before surgery?
Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.
Preparing for surgery
Understand exactly what surgery is planned, along with the risks, benefits, and other options.
Tell your doctors ALL the medicines, vitamins, supplements, and herbal remedies you take. Some of these can increase the risk of bleeding or interact with anesthesia.
If you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, be sure to talk to your doctor. He or she will tell you if you should stop taking these medicines before your surgery. Make sure that you understand exactly what your doctor wants you to do.
Your doctor will tell you which medicines to take or stop before your surgery. You may need to stop taking certain medicines a week or more before surgery. So talk to your doctor as soon as you can.
If you have an advance directive, let your doctor know. It may include a living will and a durable power of attorney for health care. Bring a copy to the hospital. If you don't have one, you may want to prepare one. It lets your doctor and loved ones know your health care wishes. Doctors advise that everyone prepare these papers before any type of surgery or procedure.
What happens on the day of surgery?
Follow the instructions exactly about when to stop eating and drinking. If you don't, your surgery may be canceled. If your doctor told you to take your medicines on the day of surgery, take them with only a sip of water.
Take a bath or shower before you come in for your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.
Do not shave the surgical site yourself.
Take off all jewelry and piercings. And take out contact lenses, if you wear them.
At the hospital or surgery center
Bring a picture ID.
The area for surgery is often marked to make sure there are no errors.
You will be kept comfortable and safe by your anesthesia provider. The anesthesia may make you sleep. Or it may just numb the area being worked on.
The surgery will take about 15 to 60 minutes.
Be sure you have someone to drive you home. Anesthesia and pain medicine make it unsafe for you to drive.
You will be given more specific instructions about recovering from your surgery. They will cover things like diet, wound care, follow-up care, driving, and getting back to your normal routine.
When should you call your doctor?
You have questions or concerns.
You don't understand how to prepare for your surgery.
You become ill before the surgery (such as fever, flu, or a cold).
You need to reschedule or have changed your mind about having the surgery.
