Carpal Tunnel Syndrome: Symptoms, Diagnosis, and Treatment Options

Carpal tunnel syndrome (CTS) occurs when the median nerve in the wrist gets compressed, causing pain, tingling, and numbness in the hand. The carpal tunnel is a narrow passageway that contains the median nerve and tendons that bend the fingers. When pressure builds on the median nerve, it interrupts communication between the hand and the brain, causing the uncomfortable sensations we feel in the fingers.

Carpal Tunnel Syndrome symptoms

The symptoms of carpal tunnel syndrome include:

• Numbness or tingling in the fingers, particularly the thumb, index, middle, and ring fingers
• Numbness or pain that worsens at night and wakes you up from sleep
• Shock-like sensations that radiate to the thumb, index, middle and ring fingers
• Weakness in the hands - difficulty in holding and gripping items

If you experience these symptoms, it’s important to seek medical advice for early diagnosis and treatment to prevent further complications.

Carpal Tunnel Syndrome Risk Factors

The risk factors for carpal tunnel syndrome vary, with certain individuals being more prone to developing the condition due to genetics, lifestyle, and health conditions.

• Women are more likely to develop carpal tunnel syndrome than men.
• In some people, their carpal tunnel is naturally smaller, which increases the risk of developing carpal tunnel syndrome.
• Those with a family history of carpal tunnel syndrome may be at risk of developing carpal tunnel syndrome.
• Repetitive hand and wrist movements over an extended period can also cause nerve pinching.
• People with health conditions such as diabetes, rheumatoid arthritis, and thyroid gland imbalance are at a higher risk, too.
• During pregnancy, some women may experience swelling that results in pressure on the nerve due to hormonal changes.

Understanding these risk factors can help you take preventive measures and seek early treatment if necessary, especially if you are at higher risk for developing carpal tunnel syndrome.

Carpal Tunnel Syndrome Diagnosis

Your doctor would first question your general health and symptoms before conducting a thorough physical examination.

Diagnosis is made based on your reported symptoms, physical examination, and investigations.

• Electrophysiological tests, such as nerve conduction studies (NCS) and electromyogram (EMG) can be used to evaluate if there is too much pressure on your median nerve.
• X-rays provide images of dense structures like bones.
• High-frequency sound waves are used in an ultrasound to help create images of bone and tissue. An ultrasound of the wrist may be suggested to check for signs of median nerve compression.
• Magnetic Resonance Imaging (MRI) scans provide detailed images of the soft tissue.

Carpal Tunnel Syndrome Treatment

If carpal tunnel syndrome is left untreated for an extended period, it can worsen and cause dysfunction of the hand, including loss of sensation in the fingers.

There are several surgical and non-surgical treatment options for carpal tunnel syndrome.

Non-surgical Treatment Options for Carpal Tunnel Syndrome

• Wear a wrist splint at night to relieve pressure on the nerve by keeping your hands in a neutral position.
• Avoid or minimise activities that require the flexing and extension of the hand and wrist for a prolonged time.
• Steroids are a powerful anti-inflammatory medication that can be injected into the carpal tunnel to calm a flare-up of symptoms or to relieve painful symptoms. 
• Hand exercises may be beneficial for some patients.

Surgical Treatment Options for Carpal Tunnel Syndrome

Surgery may only be recommended if symptoms such as pain, numbness, and tingling sensation on a moderate to severe degree last six months or longer, or if other treatments have not improved your symptoms.

• In the open carpal tunnel release surgery, a small incision is made in the wrist, and the transverse carpal ligament is cut to ease the pressure on the median nerve.
• During the endoscopic carpal tunnel release surgery (minimally invasive carpal tunnel surgery), the surgeon makes a small incision in the wrist and inserts an endoscope (a camera attached to a narrow tube) to view the inside of your wrist. A special knife is then used to cut the transverse carpal ligament, similar to the open carpal tunnel release.

In most instances, carpal tunnel surgery is performed as a day-care procedure, and you are not required to stay overnight at the hospital.

Carpal Tunnel Syndrome Prevention

There are no specific methods to prevent carpal tunnel syndrome. However, you can minimise the risk by practising the techniques below: 

• Take frequent breaks. Occasionally, stretch and gently flex your wrists.
• Maintain good posture.
• Keep your hands warm.
• Ensure the computer mouse does not strain your wrist.
