What is Carpal Tunnel Syndrome?

Carpal Tunnel Syndrome, is a nerve entrapment disorder that occurs as a result of the compression of the nerve located in the wrist called the median nerve. The median nerve passes through the wrist and controls the thumb, index finger, middle finger, and a part of the ring finger of the hand. While regulating the movements and sensations of the hand, this nerve passes through the carpal tunnel, which is a narrow canal of the wrist.

This syndrome occurs with the increase of pressure on the median nerve and is usually associated with repetitive strains in hand and wrist movements. Carpal Tunnel Syndrome manifests itself with symptoms such as numbness, tingling, weakness, and pain in the hand, and if left untreated, it can significantly affect a person's daily life.

This condition can be seen in a wide range of people, from office workers to carpenters. However, with early diagnosis and treatment, symptoms can be brought under control and its progression can be stopped.

Carpal Tunnel Syndrome is a common condition associated with the modern lifestyle. It is important to consult a specialist early on to improve the quality of daily life and for treatment.

What Are the Symptoms of Carpal Tunnel Syndrome?

Carpal Tunnel Syndrome manifests itself with various symptoms due to pressure on the median nerve in the hand and wrist. These symptoms often worsen over time and can negatively affect a person's quality of life. The most common symptoms of Carpal Tunnel Syndrome are:

Numbness and Tingling in the Hand and Fingers

• It is felt in the thumb, index finger, middle finger, and half of the ring finger.
• Numbness is usually more intense at night and can wake him from sleep.
• Waking up with numbness in the hands in the mornings is common.

Pain and Discomfort

• Pain may occur in the wrist and palm.
• The pain can spread to the arm and even the shoulder.
• Pain may increase during hand movements.

Weakness and Difficulty Gripping

• He may experience difficulty gripping or carrying items.
• Dropping problems are frequently seen in the hands.
• Weakness of the thumb muscles becomes prominent in later stages.

Burning or Shock Sensation in the Fingers

• A sensation similar to an electric shock may occur in the fingers.
• This sensation intensifies especially when the median nerve is under pressure.

Difficulty in Daily Activities

• He may experience difficulty in tasks requiring fine motor skills, such as writing and buttoning.
• Symptoms may increase during repetitive movements such as computer use.

Increase in Nighttime Symptoms

• Due to the position of the median nerve, numbness and pain are felt more intensely at night.
• He may try to relieve the numbness by shaking his wrist.

Symptoms of Carpal Tunnel Syndrome can progress over time and, if left untreated, can lead to permanent damage to the hand muscles. Therefore, when the above symptoms are noticed, consulting a specialist is of vital importance for early diagnosis and treatment.

What Causes Carpal Tunnel Syndrome?

Carpal Tunnel Syndrome occurs as a result of the compression of the median nerve passing through a narrow canal called the carpal tunnel located in the wrist. This compression disrupts the normal function of the nerve, leading to symptoms such as pain, numbness, and weakness in the hand and fingers. The factors causing the development of the condition are generally associated with repetitive movements, traumas, and certain health problems.

Main Causes of Carpal Tunnel Syndrome:

Repetitive Hand and Wrist Movements:

• Long-term computer use (keyboard and mouse usage).
• Occupations involving constant repetitive movements, such as assembly line work.
• Jobs that strain the wrist, such as sewing, writing, carpentry, and cooking.
• Playing musical instruments (especially instruments like the piano and guitar).

Wrist and Hand Traumas:

• Wrist fractures, dislocations, or impacts can disrupt the structure of the carpal tunnel.
• Narrowing in the tunnel may occur after sports injuries or accidents.

Anatomical Factors:

• The carpal tunnel being genetically narrow.
• Congenital deformities in the wrist.

Inflammation and Swelling:

• Inflammatory diseases such as rheumatoid arthritis can cause swelling in the carpal tunnel.
• Tendon inflammations (tendinitis) can also trigger this condition.

Hormonal Changes:

• Pregnancy: Fluid accumulation may occur in the carpal tunnel due to the effect of hormones.
• Menopause: Hormonal changes can trigger nerve compression.
• Thyroid gland diseases.

6. Systemic Diseases:

• Diabetes: Increases the risk of nerve damage.
• Obesity: The increase in adipose tissue around the wrist can narrow the tunnel.
• Kidney diseases: Swelling in the wrist may occur due to fluid imbalance in the body.

7. Occupational and Lifestyle Factors:

• Continuous phone or tablet use.
• Jobs performed without paying attention to wrist ergonomics.
• Heavy lifting or demanding sports.

Risk Factors:

• It is seen more frequently in women, especially in the middle-aged group.
• The risk increases in individuals with a family history.
• Smoking can increase the risk of Carpal Tunnel Syndrome by affecting the oxygenation of the nerves.

Carpal Tunnel Syndrome usually occurs when multiple factors come together. Reducing risk factors and paying attention to wrist ergonomics can be effective in preventing the syndrome. Early diagnosis and intervention are important to stop the progression of nerve compression.

How Is Carpal Tunnel Syndrome Diagnosed?

The diagnosis of Carpal Tunnel Syndrome is made based on the patient's complaints, physical examination, and necessary diagnostic tests. Symptoms caused by the compression of the median nerve are an important guide during the diagnostic process. Steps followed in diagnosing Carpal Tunnel Syndrome:

Taking the Patient History:

• The doctor listens to the patient's complaints such as pain, numbness, and weakness in the wrist.
• It is questioned when the symptoms started and with which movements they increase or decrease.
• Occupational activities, repetitive hand movements, or a history of trauma are evaluated.

Physical Examination:

• The doctor checks for tenderness, muscle weakness, or loss of sensation in the hand and wrist.
• A test for numbness or tingling in the median nerve distribution is performed.

Special Clinical Tests:

• Phalen Test: The patient bends his wrist 90 degrees and waits for a while. The occurrence of tingling or pain in this position is a positive sign for Carpal Tunnel Syndrome.
• Tinel Sign: The doctor taps lightly on the wrist. Feeling tingling or pain along the median nerve is important for diagnosis.
• Hand Grip Strength Test: The decrease in gripping strength is evaluated.

Electrophysiological Tests:

• Nerve Conduction Study (NCS): Used to measure the conduction velocity of the median nerve. Nerve compression is detected and the diagnosis is confirmed.
• Electromyography (EMG): Measures the electrical activity of muscles and nerves. Evaluates the degree of nerve compression and its effect on the muscles.

Imaging Methods:

• Ultrasonography: Used to visualize the structure of the median nerve and the condition of the carpal tunnel. Helpful in confirming nerve compression.
• Magnetic Resonance Imaging (MRI): Examines the structure of the carpal tunnel and the pressure on the nerve in detail in more complex cases.

Points to Consider During the Diagnostic Process:

• A detailed evaluation should be made to avoid confusion with other conditions showing similar symptoms (e.g., cervical hernia, rheumatic diseases).
• Early diagnosis in particular increases treatment success and prevents progressive nerve damage.

If he has symptoms of Carpal Tunnel Syndrome, it is important to consult a specialist to have the necessary examinations and tests for an accurate diagnosis. Early intervention helps maintain his quality of life.

How Is Carpal Tunnel Syndrome Treated?

Carpal Tunnel Syndrome treatment may vary depending on the severity of the disease, the duration of symptoms, and the individual's lifestyle. Treatment methods usually begin with non-surgical approaches, but surgical intervention may be required in advanced cases. Methods used in the treatment of Carpal Tunnel Syndrome:

• Occupations Requiring Manual Labor: Carpenters and turners using hand tools.
• Healthcare Professionals: Continuous use of injectors and jobs requiring precise hand movements.

Genetic Predisposition

• A congenitally narrow carpal tunnel can increase the risk of nerve compression.
• The risk is higher in individuals with a family history of Carpal Tunnel Syndrome.

Health Problems

• Diabetes: The risk of nerve damage increases.
• Obesity: Excess weight can cause the tunnel to narrow by placing pressure on the tissues around the wrist.
• Rheumatoid Arthritis: Can trigger nerve compression by causing inflammation in the wrist.
• Hypothyroidism: The slowing of metabolism can lead to fluid accumulation and swelling in the wrist.

Hormonal and Physical Changes

• Pregnancy: Changes in hormone levels can cause fluid retention and swelling in the wrist.
• Menopause: Hormonal changes can trigger nerve compression.
• Hand and Wrist Injuries: Fractures, dislocations, or impacts can disrupt the structure of the carpal tunnel.

Lifestyle Factors

• Smoking: Can lead to nerve damage by reducing the oxygenation of the nerves.
• Posture Disorders: Continuous use of the hand and wrist in an incorrect position.
• Intense Physical Activity: Excessive straining of the wrist during heavy lifting or sports.

Gender and Age

• Women: The carpal tunnel is narrower in women compared to men; this increases the risk of nerve compression.
• Age: The risk increases in individuals over 40 years of age because connective tissues lose their elasticity with age.

To protect against Carpal Tunnel Syndrome, it is important to make lifestyle changes taking these risk factors into account, to pay attention to occupational ergonomics, and to have regular health check-ups. Taking early precautions can prevent the progression of the syndrome.

What Are the Complications?

When Carpal Tunnel Syndrome is left untreated or allowed to progress, it can lead to serious complications. These complications are related both to the increase in pressure on the median nerve and the impairment of the hand's motor and sensory functions. Common complications of Carpal Tunnel Syndrome:

Nerve Damage

• Long-term nerve compression can lead to permanent damage to the median nerve.
• Impairment in nerve conduction, loss of sensation, and severe losses in motor functions can be observed.

Weakness in Hand and Finger Muscles

• When untreated, the thumb muscles (thenar muscle group) weaken and shrink (atrophy).
• Gripping and carrying items can become difficult.

Loss of Sensation and Feeling

• Permanent numbness and tingling can be seen in the thumb, index finger, middle finger, and part of the ring finger.
• In advanced stages, loss of sensation can become irreversible.

Difficulties in Daily Life

• Due to the loss of grip strength, basic activities such as writing, buttoning, or lifting items become difficult.
• Severe problems can be experienced in tasks requiring fine motor skills.

Chronic Pain

• If pressure on the median nerve is not treated, a constant sensation of pain can occur in the hand and wrist.
• Pain can spread to the arm and shoulder, severely affecting the quality of daily life.

Deformity of the Hand

• The shrinking of hand muscles (atrophy) can lead to a pronounced deformity in the thumb area.
• This condition is usually seen in advanced stages of nerve compression.

Post-Surgical Complications

• There may be a risk of infection, bleeding, or nerve damage after surgical treatment.
• There is a possibility of nerve compression reoccurring after surgery (recurrence).

Psychological Effects

• Chronic pain and difficulties in daily activities can cause psychological problems such as depression and anxiety.

Complications of Carpal Tunnel Syndrome usually occur when treatment is delayed. Therefore, consulting a specialist in the early period when symptoms are noticed is of critical importance to prevent its progression and avoid these complications. With treatment, nerve compression can be brought under control and serious complications can be prevented.

Carpal Tunnel Tests

Tests used in the diagnosis of Carpal Tunnel Syndrome are performed to evaluate the degree of median nerve compression and to rule out other diseases showing similar symptoms. Common tests used to diagnose Carpal Tunnel Syndrome:

Physical Examination Tests

• Tinel Test: The doctor taps lightly on the wrist area. If tingling or pain is felt along the median nerve, the test is considered positive.
• Phalen Test (Wrist Flexion Test): The patient bends his wrist 90 degrees, presses his hands together, and holds this position for 1-2 minutes. If numbness, tingling, or pain is felt in the hand or fingers during this time, the test is considered positive.
• Hand Grip Strength Test: A decrease in grip strength can be a sign of pressure on the median nerve.
• Durkan Test (Wrist Compression Test): The doctor applies direct pressure to the wrist. If numbness or tingling is felt along the median nerve, the test is considered positive.

Nerve Conduction Study (NCS)

• The speed of electrical impulses passing through the median nerve is measured.
• A slowdown in nerve conduction helps make a definitive diagnosis of Carpal Tunnel Syndrome.

Electromyography (EMG)

• Electrical signals transmitted by nerves to muscles are measured.
• Used to evaluate the effect of median nerve compression on muscles.

Imaging Tests

• Ultrasonography: The median nerve and surrounding tissues are visualized. It provides information about the degree of nerve compression and the condition of the tunnel.
• Magnetic Resonance Imaging (MRI): Shows the structure of the carpal tunnel and the pressure on the median nerve in detail. Used in complex cases.

Blood Tests

• Can be performed to check for the presence of systemic diseases that trigger Carpal Tunnel Syndrome, such as diabetes, hypothyroidism, or rheumatoid arthritis.

In the diagnosis of Carpal Tunnel Syndrome, physical tests are usually applied as the first step. In suspicious cases, the diagnosis is confirmed using nerve conduction studies or imaging methods. Early diagnosis increases treatment success and helps prevent complications.

Carpal Tunnel Syndrome Surgery

When Carpal Tunnel Syndrome progresses and non-surgical treatments are insufficient to alleviate symptoms, surgery becomes one of the most effective treatment methods. Surgery aims to alleviate pain, numbness, and loss of strength in the hand and fingers by reducing pressure on the median nerve.

When Is Surgery Necessary?

• If pain, numbness, and weakness cannot be controlled with non-surgical methods.
• If symptoms of nerve damage (e.g., muscle weakness or muscle shrinking) have begun.
• If nighttime pain and sleep problems are severe.
• If daily activities are seriously affected.

Surgical Methods

• Open Carpal Tunnel Release Surgery: It is a traditional method. A small incision is made in the wrist, the carpal tunnel connective tissue is cut, and the pressure on the median nerve is removed.
• Endoscopic Carpal Tunnel Surgery: It is a minimally invasive method. The carpal tunnel connective tissue is cut with the help of an endoscope entered through small incisions. Recovery time is faster and less tissue damage occurs.

Surgical Process

• Surgery is usually performed under local or regional anesthesia.
• The procedure usually takes 20-30 minutes.
• Patients are usually discharged on the same day.

Post-Surgical Recovery Process

• There may be mild pain or tenderness in the hand and wrist for the first few weeks.
• Physical therapy and hand exercises are important in regaining the hand's mobility.
• Patients can usually return to their normal activities within 4-6 weeks.

Risks and Complications of Surgery

• Infection
• Bleeding
• Nerve or vessel damage
• Persistence of pain or tenderness in the median nerve after surgery
• In rare cases, the risk of recurrence of Carpal Tunnel Syndrome
• Success Rate of Surgery
• Carpal Tunnel Syndrome surgeries generally have a high success rate (around 90%).
• When nerve compression is completely relieved, pain and numbness are largely reduced.

Carpal Tunnel Syndrome surgery offers an effective and permanent solution in advanced stage cases. However, when making a surgical decision, it is important to conduct a detailed evaluation with a specialist. Following doctor recommendations and the rehabilitation program during the recovery process is essential for a full recovery.
