Surgery for carpal tunnel syndrome
Doctors diagnose over
8 million people a year with carpal tunnel syndrome. And about
500,000 of them decide to treat it with surgery. The remainder use non-surgical remedies.
The technical term for this hand operation is
"carpal tunnel release surgery". It's specifically designed for relieving symptoms of carpal tunnel syndrome.
Doctors perform the surgery in one of two ways:
open or endoscopic.
You will have one of these procedures, depending on which one your doctor is comfortable and experienced with.
Both of these surgical techniques have a
success rate of about 50%. This is based on patient satisfaction at 6 months. The
primary reasons for dissatisfaction (including patient complaints) are:
- Persistent pain
- Symptoms didn't resolve
- Symptoms returned
- Poor hand function & weakness
What to expect during carpal tunnel surgery
Both operative procedures are generally performed on an outpatient basis.
For the open technique, you're usually given an intravenous
general anesthesia which puts you to sleep. For the open technique, you're generally given a
nerve block in the arm which deadens your hand while you remain awake.
The doctor then makes the incision in your hand.
- For open surgery, you'll have a 2-3" long incision from your wrist to your palm.
- For endoscopic surgery, you'll have either one or two small holes in your hand.
The incisions allow the doctor to see the
transverse carpal ligament. This ligament is a band of tough tissue connecting both sides of your hand. The doctor uses a scalpel to cut the ligament. When cut, the ligament lets your wrist bones snap apart. This relieves pressure on the
median nerve directly beneath it.
Open carpal tunnel surgery takes 40--20-30 minutes. Endoscopic surgery takes 40-60 minutes. Once the operation is complete, the staff wraps bandages around your hand. When you're fully awake (1-2 hours later) you're sent home to recover.
The surgical staff will give you
special written instructions to follow at home.
