Do I need surgery for carpal tunnel syndrome?

In short

Most people with carpal tunnel syndrome do not need surgery. Dr. Knight runs a ladder that starts with changing the activity and wearing a wrist brace at night, then an anti-inflammatory, then a cortisone injection, and he treats surgery as the last rung. Surgery is considered when those steps fail or when the nerve is already losing feeling and strength.

What carpal tunnel syndrome is, and what the decision turns on

Let's take a look at the problem before the treatment, because the decision follows from what the nerve is doing. The carpal tunnel is a passage in the front of the wrist with a stiff band across its roof, and the nerve that serves your thumb, index, middle and half of your ring finger runs through it with the finger tendons. Swelling in a space that cannot expand presses on that nerve, which is where the numbness, the tingling that wakes you at night, and eventually the clumsiness with buttons and pens come from.¹ So the question is not how much it hurts. It is how far along the nerve is, and whether the pressure will come off without an operation.

Symptoms that come and go, or a nerve that is losing ground

This is the distinction Dr. Knight is weighing, and it is the one to bring to the visit. Early carpal tunnel is intermittent. The hand goes numb at night or on a long drive, you shake it out and it settles. A nerve that is losing ground behaves differently. The numbness stops leaving, feeling in the fingertips is dulled, and the muscle at the base of the thumb weakens so that you drop things and fumble buttons.¹

Here is the test you can run before your appointment. For one week, write down whether the numbness ever fully goes away. If the hand always comes back to normal, you are describing the first picture. If there is never a moment when it feels like the other hand, you are describing the second, and that is worth an exam sooner rather than later. Waiting is not neutral, because feeling and strength that have been gone a long time may not fully come back.

Dr. Knight's ladder, in his order

1. Change what is provoking it. Posture, the workstation, the keyboard and the mouse, and long stretches of repetitive use.
2. Wear a wrist brace at night. Dr. Knight calls this the number one treatment, because the wrist curls while you sleep and that raises the pressure inside the tunnel.
3. Rest the wrist and the fingers, and add an anti-inflammatory medication such as ibuprofen.
4. If that is not enough, a cortisone injection into the carpal tunnel can reduce the swelling.
5. Surgery, only once the steps above have failed, or when the exam shows the nerve already losing feeling and strength.

Where the diagnosis is not clear from the exam, Dr. Knight will arrange nerve testing and tell you where it is done.

When to call us

• The numbness no longer comes and goes and is present all the time.
• You are dropping things, or the muscle at the base of the thumb looks flatter than on the other hand.
• A night brace and an anti-inflammatory have been tried and the symptoms are unchanged.
• The numbness includes the little finger, which points away from the carpal tunnel.
• Both hands are affected, or the symptoms began during pregnancy or alongside another medical condition.
• Pain, numbness or weakness that started after a fall or a direct injury to the wrist.
