What is Carpal Tunnel?

2021-05-24

what

Carpal tunnel syndrome, commonly abbreviated as CTS, is a condition that affects the hand and wrist. It occurs when the median nerve, which runs through the carpal tunnel, is compressed. This nerve controls movement and sensation in the thumb, index finger, middle finger, and half of the ring finger.

The carpal tunnel is a narrow passageway surrounded by bones and ligaments at the base of your hand. The median nerve and tendons that bend your fingers and thumb pass through this tunnel. When the tendons become inflamed, they can press on the median nerve and cause pain, numbness, and tingling in your hand and fingers.

Carpal tunnel syndrome is a common condition that can affect people of all ages. However, it is most common in people who perform repetitive hand and wrist movements, such as computer work, typing, or playing musical instruments.

Median Nerve Compression

Median nerve compression is the main cause of carpal tunnel syndrome. The median nerve is a major nerve that runs through the carpal tunnel, a narrow passageway in your wrist. The median nerve controls movement and sensation in your thumb, index finger, middle finger, and half of your ring finger.

Inflammation: When the tendons in your wrist become inflamed, they can press on the median nerve and cause compression.
This can happen due to repetitive hand and wrist movements, such as typing, using a computer mouse, or playing musical instruments.
Trauma: A wrist fracture or dislocation can also damage the median nerve and cause carpal tunnel syndrome.
This type of injury is more common in athletes and people who work in manual labor jobs.
Anatomic Abnormalities: Some people are born with a smaller carpal tunnel, which can increase the risk of median nerve compression.
This is a less common cause of carpal tunnel syndrome.
Medical Conditions: Certain medical conditions, such as rheumatoid arthritis, diabetes, and obesity, can also increase the risk of developing carpal tunnel syndrome.
This is because these conditions can cause inflammation and swelling in the wrist.

Median nerve compression can cause a variety of symptoms, including pain, numbness, tingling, and weakness in the hand and wrist. These symptoms can range from mild to severe. In severe cases, median nerve compression can lead to permanent nerve damage.

Causes Pain, Numbness, Tingling

The pain, numbness, and tingling caused by carpal tunnel syndrome are due to the compression of the median nerve. This compression can disrupt the nerve's ability to send signals to and from the hand and wrist.

Pain: The pain associated with carpal tunnel syndrome can range from mild to severe. It is often described as a burning, tingling, or aching pain in the hand and wrist.
The pain may also be worse at night or when you are holding something in your hand.
Numbness: Carpal tunnel syndrome can also cause numbness in the thumb, index finger, middle finger, and half of the ring finger.
This numbness may be constant or intermittent.
Tingling: Tingling is another common symptom of carpal tunnel syndrome. It is often described as a pins and needles sensation in the hand and wrist.
Tingling may also be worse at night or when you are holding something in your hand.
Weakness: In severe cases of carpal tunnel syndrome, you may experience weakness in your hand and wrist. This can make it difficult to perform everyday tasks, such as gripping objects or making a fist.
Weakness may also be a sign of permanent nerve damage.

The symptoms of carpal tunnel syndrome can vary depending on the severity of the condition. Some people may only experience mild symptoms, while others may have more severe symptoms that interfere with their daily activities.

Common in Repetitive Hand Movements

Carpal tunnel syndrome is common in people who perform repetitive hand and wrist movements. This is because these movements can cause inflammation of the tendons in the wrist, which can then press on the median nerve and cause compression.

Some of the most common activities that can lead to carpal tunnel syndrome include:

Typing: Typing is a common cause of carpal tunnel syndrome, especially if you type for long periods of time without taking breaks.
Using a computer mouse: Using a computer mouse can also contribute to carpal tunnel syndrome, especially if you use it for long periods of time without taking breaks.
Playing musical instruments: Playing musical instruments that require repetitive hand and wrist movements, such as the piano, guitar, or violin, can also increase the risk of developing carpal tunnel syndrome.
Working in manual labor jobs: People who work in manual labor jobs that require repetitive hand and wrist movements, such as construction, assembly line work, or factory work, are also at an increased risk of developing carpal tunnel syndrome.

In addition to these specific activities, any activity that requires you to hold your wrist in a bent or extended position for long periods of time can increase your risk of developing carpal tunnel syndrome.

If you are concerned about your risk of developing carpal tunnel syndrome, there are a few things you can do to reduce your risk, such as:

Take frequent breaks: When you are performing repetitive hand and wrist movements, it is important to take frequent breaks to rest your hands and wrists.
Use proper ergonomics: Make sure your workstation is set up properly so that your wrists are in a neutral position.
Strengthen your wrists: Strengthening the muscles in your wrists can help to protect them from injury.

Can Affect People of All Ages

Carpal tunnel syndrome can affect people of all ages, from children to seniors. However, it is most common in people between the ages of 30 and 60.

Children and Adolescents: Carpal tunnel syndrome is rare in children and adolescents, but it can occur. It is most often caused by an underlying medical condition, such as juvenile rheumatoid arthritis or a wrist injury.
Symptoms of carpal tunnel syndrome in children and adolescents are similar to those in adults.
Adults: Carpal tunnel syndrome is most common in adults between the ages of 30 and 60. This is because adults in this age group are more likely to perform repetitive hand and wrist movements in their jobs or hobbies.
Symptoms of carpal tunnel syndrome in adults can range from mild to severe.
Seniors: Carpal tunnel syndrome is also common in seniors. This is because the tendons in the wrist can become thicker and less flexible with age, which can increase the risk of compression of the median nerve.
Symptoms of carpal tunnel syndrome in seniors are similar to those in adults.
Pregnant Women: Pregnant women are also at an increased risk of developing carpal tunnel syndrome. This is because the hormonal changes of pregnancy can cause the ligaments in the wrist to relax, which can put pressure on the median nerve.
Symptoms of carpal tunnel syndrome in pregnant women usually improve after childbirth.

Anyone can develop carpal tunnel syndrome, regardless of their age or occupation. However, certain factors can increase your risk of developing this condition.

Treated with Rest, Medication, Therapy

Carpal tunnel syndrome can be treated with a variety of methods, including rest, medication, and therapy.

Rest: One of the best ways to treat carpal tunnel syndrome is to rest your hand and wrist. This means avoiding activities that aggravate your symptoms. You may also need to wear a splint or brace to help keep your wrist in a neutral position.
Rest can help to reduce inflammation and swelling in the wrist.
Medication: There are a number of medications that can be used to treat carpal tunnel syndrome. These medications can help to reduce pain, inflammation, and swelling. Some common medications used to treat carpal tunnel syndrome include nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, and corticosteroids.
Medication can be helpful in reducing the symptoms of carpal tunnel syndrome, but it is important to note that it does not cure the condition.
Therapy: Physical therapy and occupational therapy can be helpful in treating carpal tunnel syndrome. Physical therapy can help to strengthen the muscles in your wrist and improve your range of motion. Occupational therapy can help you to learn how to perform everyday activities in a way that does not aggravate your symptoms.
Therapy can be a very effective way to treat carpal tunnel syndrome and help you to manage your symptoms.
Surgery: In some cases, surgery may be necessary to treat carpal tunnel syndrome. Surgery is usually only recommended if other treatments have failed to relieve your symptoms. During surgery, the surgeon will cut the ligament that is pressing on the median nerve. This will relieve the pressure on the nerve and allow it to function properly.
Surgery is a major procedure, but it can be very effective in treating carpal tunnel syndrome.

The best treatment for carpal tunnel syndrome will vary depending on the severity of your symptoms and your individual needs. Talk to your doctor about the best treatment options for you.

Surgery May Be Necessary in Severe Cases

Surgery is usually only recommended for people with severe carpal tunnel syndrome who have not responded to other treatments. Surgery may also be necessary if you have damage to the median nerve.

Carpal Tunnel Release: The most common type of surgery for carpal tunnel syndrome is called carpal tunnel release. During this surgery, the surgeon will cut the ligament that is pressing on the median nerve. This will relieve the pressure on the nerve and allow it to function properly.
Carpal tunnel release surgery is usually performed on an outpatient basis. This means that you will be able to go home the same day as your surgery.
Nerve Repair: In some cases, surgery may be necessary to repair the median nerve. This is usually only done if the nerve has been severely damaged.
Nerve repair surgery is a more complex procedure than carpal tunnel release surgery. It may require a longer recovery time.
Tendon Transfer: In some cases, surgery may be necessary to transfer a tendon from another part of the hand to the thumb. This is usually done to improve the function of the thumb.
Tendon transfer surgery is a major procedure. It may require a long recovery time.
pollicization: In severe cases, pollicization surgery may be necessary. This surgery involves fusing the thumb to the index finger, creating a new thumb.
Pollicization surgery is a major procedure. It may require a long recovery time.

The type of surgery that is best for you will depend on the severity of your symptoms and your individual needs. Talk to your doctor about the best surgical option for you.
