Description
Dr. Nathan Lesley explains carpal tunnel syndrome, a common condition involving a pinched median nerve. Symptoms include numbness and tingling of the fingers. Dr. Lesley will recommend noninvasive treatments before considering surgical treatment.

Carpal tunnel syndrome is common.
[00:00:09.160]
It's one of the most common things we see.
[00:00:10.960]
At the most simple level,
[00:00:13.560]
it's just a nerve that's being pinched.
[00:00:16.600]
We have a nerve called the median nerve
[00:00:18.200]
that travels from the brain all the way to the fingertips.
[00:00:21.520]
It passes through a space in the palm here,
[00:00:25.120]
and that space is called the carpal tunnel.
[00:00:27.080]
There's a lot of things that live inside the carpal tunnel,
[00:00:29.440]
primarily that nerve,
[00:00:31.280]
but also all the tendons.
[00:00:33.160]
There's nine tendons that move your fingers
[00:00:35.840]
and those have to share the carpal tunnel with the nerve.
[00:00:39.560]
The problem is the tunnel gets too tight.
[00:00:42.000]
When the tunnel becomes too tight,
[00:00:43.480]
the little arteries that supply the nerve
[00:00:47.080]
become pinched off and the nerve doesn't work.
[00:00:49.840]
They can also occur because of those tendons.
[00:00:51.880]
The nine tendons that share that space swell up.
[00:00:55.400]
The pressure within the carpal tunnel rises
[00:00:58.440]
and the nerve doesn't get the necessary blood,
[00:01:01.440]
so it goes to sleep.
[00:01:02.880]
The most common symptoms of carpal tunnel syndrome
[00:01:05.640]
are numbness and tingling of the fingers,
[00:01:07.760]
primarily the thumb through half of the ring finger.
[00:01:12.000]
This side of the hand becomes numb.
[00:01:15.960]
It burns.
[00:01:16.880]
People will describe electric sensations or tingling.
[00:01:20.360]
Sometimes it can be severe pain.
[00:01:22.200]
I will see patients who haven't slept.
[00:01:24.480]
Other times its not as much pain,
[00:01:26.120]
it's just numbness
[00:01:27.240]
or they will complain of dropping objects
[00:01:29.600]
or not being able to feel when they button their shirt.
[00:01:33.160]
The symptoms can vary.
[00:01:35.000]
But to some degree, most of the time people have numbness and some pain.
[00:01:38.680]
We start treating carpal tunnel syndrome
[00:01:40.880]
with the minimally invasive or least invasive methods.
[00:01:47.200]
Anti-inflammatory medication is one.
[00:01:49.760]
A nighttime splint can be very helpful for patients.
[00:01:52.640]
We routinely try steroids.
[00:01:55.600]
Inside the carpal tunnel,
[00:01:57.760]
there's inflammation going on.
[00:01:59.320]
That's what's causing those tendons to swell.
[00:02:01.240]
If we can reduce that inflammation through the use of steroid,
[00:02:05.080]
either a pill or an injection,
[00:02:07.320]
oftentimes that will help.
[00:02:09.040]
Ultimately, if all of this fails,
[00:02:11.160]
then the treatment of choice is to open the carpal tunnel.
[00:02:14.760]
The recovery from carpal tunnel surgery has improved significantly
[00:02:18.440]
even in my 15-year career.
[00:02:20.960]
The recovery for the carpal tunnel surgery performed nowadays
[00:02:25.360]
and certainly the ones that are performed here,
[00:02:27.480]
it's much different.
[00:02:28.800]
We allow immediate use of the hand,
[00:02:30.520]
full range of motion.
[00:02:32.400]
I do not recommend the use of a splint.
[00:02:35.400]
We just put a soft bandage
[00:02:36.880]
and allow patients to go back to full use immediately.
[00:02:40.600]
There is a small incision, so we want to protect that and prevent infection.
[00:02:44.680]
That means keeping it dry for a matter of days.
[00:02:47.200]
I usually place two sutures
[00:02:49.480]
and those are left in place for about 6-8 days.
[00:02:53.880]
But return to most activities is immediate.
[00:02:56.240]
Return to heavy lifting activities
[00:02:58.920]
or working as a mechanic or a carpenter
[00:03:02.080]
will be on the order of a week or two
[00:03:04.240]
before I would recommend that you attempt that.
