Understanding the condition

What is Carpal Tunnel Syndrome?

Carpal tunnel syndrome occurs when the median nerve is compressed as it passes through a narrow passage at the wrist, alongside the tendons that bend the fingers.

The nerve provides feeling to the thumb, index and middle fingers and part of the ring finger. The little finger is usually unaffected. It also supplies some of the muscles at the base of the thumb.

Symptoms may develop gradually, sometimes without an obvious cause. Pregnancy, diabetes, arthritis and certain medical conditions can increase the likelihood of developing carpal tunnel syndrome. Symptoms can also be aggravated by tasks involving sustained gripping or bent wrist positions.

When to Seek Urgent Care

Know the Warning Signs

Carpal tunnel syndrome usually develops gradually and is rarely an emergency. However, arrange prompt medical assessment if you notice:

  • Numbness becoming constant rather than intermittent.
  • Increasing weakness of the thumb or difficulty gripping and pinching.
  • Visible wasting of the muscles at the base of the thumb, or a clear decline in hand function.

These changes can indicate more advanced compression of the median nerve. Delaying treatment may reduce the chance of full nerve recovery.

For emergencies, call 000 or attend your nearest Emergency Department.

Assessment & Imaging

How is it diagnosed?

Diagnosis is usually based on symptoms and examination findings. Nerve conduction studies are commonly used to confirm the diagnosis and assess the severity of nerve compression.

Clinical Assessment

Which symptoms and which fingers are affected, any night symptoms, and how they interfere with function.

Neurological Examination

Testing includes hand sensation, strength, muscle wasting and hand function.

Nerve Conduction Studies

Measure how fast electrical signals travel through the median nerve.

Treatment

Treatment Options

Treatment depends on the severity and duration of symptoms, whether there is evidence of nerve damage, and how much your hand function is affected. Mild symptoms can often be managed without surgery.

Many patients improve with conservative treatment.

Treatment may include:

  • Activity modification
  • Wrist splinting
  • Physiotherapy
  • Anti-inflammatory medication
  • Corticosteroid injections

Surgery may be recommended when symptoms are severe, progressive, or fail to respond to conservative treatment.
