Carpal Tunnel Syndrome

What is it?

The carpal tunnel is a part of the anatomy of your wrist. It’s a passageway that contains tendons and the median nerve. It’s on the palm side of your wrist – when you bend your fingers into a fist, the tendons that pull your fingers into your palm travel through the carpal tunnel. The boundaries of the tunnel are formed by bones and a tight ligament called the transverse carpal ligament. It’s the structure closest to your skin in the region of the carpal tunnel – it forms the palm-sided “roof” of the carpal tunnel.

The following picture is a drawing of the anatomy of the carpal tunnel superimposed on a picture of my hand. Click the picture to read the full article on the cross section anatomy of the carpal tunnel:

Carpal tunnel syndrome is a syndrome because patients have a wide variety of symptoms. All these symptoms are related to compression (or pinching) of the blood flow within the median nerve.

The median nerve (inside the tunnel) is about as thick as a pencil and supplies sensation (feeling) to the thumb, index (pointer) finger, middle finger, and half of the ring finger.

Carpal tunnel syndrome is not just numbness or just pain. It can be a combination of both. The numbness and pain of carpal tunnel syndrome happen when the median nerve’s blood supply is squeezed by increased pressure in the carpal tunnel. This is similar to what happens when you step on a garden hose full of running water – the flow slows down or stops! This may cause numbness, tingling, “pins and needles”, and pain or aching – these symptoms may be there constantly or come and go during the day or night.

What are the Causes?

Carpal tunnel syndrome can be caused by a variety of things. Here are some examples:

  • swelling or inflammation around tendons
  • increased fluid or edema in the body
  • wrist fractures or other injuries
  • arthritis
  • diabetes
  • tumors
  • hypothyroidism
  • pregnancy

Certain work activities may make the symptoms of carpal tunnel syndrome worse. These activities may include repeated bending of the wrist or fingers, accompanied by strong gripping. Constant use of vibrating machinery or tools may also contribute to the symptoms. However, the specific relationship between work factors and carpal tunnel syndrome is still not well-understood.

Routine daily activities and hobbies may also contribute to worsening symptoms. Holding a book for long periods, use of power tools, driving, or crocheting are examples of common activities that may provoke symptoms.

What are the signs and symptoms?

Most patients with carpal tunnel syndrome have numbness, tingling and/or pain. Usually the small finger is not involved. The numbness may wake you up from sleep. Sometimes it helps to “shake it out” or massage the hand or wrist. Symptoms may be bilateral (on both sides) or involve only one side.

Patients may describe a feeling of clumsiness or weakness of the hand. You may notice that you drop things more often and doing fingertip-intensive tasks (like buttoning buttons) becomes difficult.

Muscle weakness/atrophy

Just below the thumb is a bulging pad of muscles called the thenar muscles. Some of these muscles control some of the thumb’s most important movements and are supplied by the median nerve. These muscles may begin to waste away with advanced carpal tunnel syndrome and make the thumb side of the palm look flattened compared with the other hand.

Treatment

Nonsurgical treatment of carpal tunnel syndrome is possible. It’s usually most effective for patients with mild symptoms. This involves avoiding activities that make symptoms worse (strong repetitive gripping, using vibrating tools, etc.). Splints are usually prescribed and are usually worn at night only, unless daytime use provides additional relief.

A steroid (cortisone) injection into the palm side of the wrist in the carpal tunnel may be recommended. This decreases swelling around the nerve and may provide lasting relief of numbness and pain.

Surgical treatment (carpal tunnel release) is recommended after nonsurgical treatment has stopped working or for patients who have more severe symptoms like muscle wasting and constant numbness.

Carpal tunnel release surgery is an outpatient procedure – you go home the same day of the surgery. This involves a small incision in the palm of your hand, near the wrist, through which the surgeon cuts (releases) the tight ligament on the palm side of the carpal tunnel. This relieves pressure on the median nerve. After surgery, you’ll have a soft dressing on your hand and begin moving your fingers right away in the recovery room to prevent stiffness.

The surgery increases blood flow to the median nerve and the first symptom to improve is night time pain and discomfort. Numbness is usually the last symptom to go away completely.

Soreness along the incision may last from 4-6 weeks. Soreness with deep pressure on the incision may last for a few months, but this is unusual. Improvements in symptoms depend on the severity and duration of those symptoms before surgery. Grip strength usually returns within three months after surgery.

Hand therapy may be recommended to reduce discomfort, regain strength, and improve range of motion in the fingers and hand.

What Dr. Henley’s Carpal Tunnel Patients Are Saying

by Allison McBride

I would highly recommend Dr. Henley. I definitely felt at ease with him and his knowledge immediately. My carpal tunnel is gone and the surgery was very simple and I recovered quickly. It’s a huge relief not to experience the symptoms of it anymore. His nurse is awesome, she’s so friendly and upbeat. All of my office visits and the surgical procedure were done in a timely manner and that is very much appreciated.

by Tonya Snell

I have had problems with both of my hands for a few years but the last 6 months have been unbearable. I was awake every hour in the night with my hands being numb and hurting so bad. I was tired all the time and in so much pain. I finally gave in and went to see Dr. Henley. He is a very caring doctor and explained what he was going to do in the surgery and how it was all going to work. I had the right hand done and 2 weeks later the left one done. The staff at the Eye Center were very nice and caring.

When I came in for my last appointment with Dr. Henley I told him the surgery truly changed my life. I could tell the first night after each surgery that my hands were fixed. I can now sleep at night and my hands have not hurt or been numb at all since the surgeries. I told him I can finally fix my hair again and that makes me happy. Thank you very much to Dr. Henley and all the staff at the Orthopaedic Clinic. It was the best experience I could have had.

 

by Kate Cox

Dr. Henley did an excellent job taking care of my carpal tunnel syndrome surgically. He considers conservative treatment first and then proceeds to surgery if necessary. I feel that this is really important in today’s medicine. He did a great job explaining the procedure and goal of surgery. He and his staff are personable, yet professional. The staff at Arkansas Outpatient Surgery Center are outstanding as well. As a nurse, I am very particular about how things are done in the medical setting. I feel that both Dr. Henley and the surgery center were exceptional in their care. I would highly recommend both.

 

by Lana Boone

I suffered with carpal tunnel in my left hand for 2 years because I was too scared to consider surgery. If I had only known how gentle and caring Dr. Henley and the surgical staff would be I would not have endured so much needless pain. The first day after surgery the numbness was completely gone and after two weeks the healing is almost complete. I would most certainly do the other hand if it becomes necessary.
