Carpal tunnel release

Overview

Carpal tunnel release is a surgical procedure to relieve pressure on the median nerve in your wrist. This nerve runs through a narrow passage called the carpal tunnel, and when it gets squeezed, you may feel numbness, tingling, or pain in your hand and fingers. The surgery cuts the ligament that presses on the nerve, giving it more space to work properly.

Yes, carpal tunnel release is one of the most common hand surgeries performed worldwide. It is often done when other treatments haven't helped enough.

This surgery is for people who have carpal tunnel syndrome that does not get better with non-surgical treatments like wrist splints or hand therapy. It can affect adults of any age, but it's more common in people who do repetitive hand movements or have conditions like diabetes or arthritis.

Symptoms

Causes

Main causes

• Carpal tunnel syndrome is caused by pressure on the median nerve inside your wrist. This pressure can happen when the carpal tunnel becomes narrower or when the tissues inside swell.

Risk factors

• Repetitive hand and wrist movements, like typing, assembly line work, or using vibrating tools
• Pregnancy (fluid retention can cause swelling)
• Health conditions like diabetes, thyroid problems, or arthritis

When to see a doctor

See a doctor urgently if:

• If you have sudden and severe pain or weakness in your hand that does not go away
• If you have had surgery and notice signs of infection (redness, swelling, fever) or severe pain

Book a routine appointment if:

• If you have ongoing numbness, tingling, or pain in your hand that affects your daily life
• If symptoms last more than a few weeks or keep coming back

Diagnosis

Your doctor will start by asking about your symptoms and examining your hand, wrist, and arm. They may do tests to confirm the diagnosis and rule out other problems.

Tests that may be done

• Physical exam: Your doctor may tap on your wrist (Tinel's sign) or bend your wrist forward (Phalen's test) to see if it brings on symptoms.
• Nerve conduction study: A simple test that measures how fast signals travel through your median nerve. It can show if the nerve is compressed.
• Electromyography (EMG): A test that checks how well your muscles respond to nerve signals.

What to expect at your appointment

The diagnosis is usually straightforward. The tests are not painful, though you may feel a little tingling during the nerve study. Your doctor will explain the results and discuss treatment options with you.

Treatment

Treatment for carpal tunnel syndrome often starts with simple, non-surgical steps to reduce pressure on the nerve. If these don't help enough, surgery (carpal tunnel release) may be recommended.

Self-care at home

• Take breaks from repetitive hand activities and shake out your hands gently
• Wear a wrist splint at night to keep your wrist in a straight, neutral position
• Apply a cold pack (wrapped in a towel) to your wrist for 10–15 minutes if it feels sore or swollen
• Do gentle hand stretches and exercises your doctor or therapist shows you

Medical treatments

Your doctor may suggest a short course of anti-inflammatory medicines (like ibuprofen) or paracetamol to reduce pain and swelling. Corticosteroid injections (a strong anti-inflammatory) into the carpal tunnel can also help relieve symptoms for a time.

Living with this condition

After surgery, you will need to keep your hand elevated and your wound clean and dry. You may have a bandage for a few days and be told to avoid heavy lifting or gripping for several weeks. Most people can return to light activities within a week or two, but full recovery can take a few months.

Lifestyle tips

• Set up your work station so your wrists are straight and your hands are relaxed (ergonomics)
• Take frequent short breaks if you do a lot of typing or manual work
• Use tools with padded handles to reduce pressure on your hand

Diet and exercise

A balanced diet rich in fruits, vegetables, and healthy fats can help reduce inflammation. Gentle hand exercises (like making a fist and then stretching your fingers) can keep your hand flexible. Ask your doctor or a hand therapist for specific exercises.

Mental health and emotional wellbeing

Living with hand pain or numbness can be frustrating and may affect your mood or sleep. It's normal to feel anxious about surgery or recovery. Talking to your healthcare team or a counsellor can help.

Prevention

Carpal tunnel syndrome cannot always be prevented, but you can reduce your risk by using good posture and ergonomics, taking breaks during repetitive activities, and managing health conditions like diabetes or weight.

Vaccines

vaccines are not related to carpal tunnel syndrome

Screening programmes

there is no routine screening test for carpal tunnel syndrome; it is diagnosed based on symptoms and tests when needed

Complications

If left untreated

• If carpal tunnel syndrome is not treated, the pressure on the nerve can lead to permanent numbness or weakness in your hand
• You may lose some fine motor skills, making it hard to do tasks like writing or buttoning clothes

Long-term outlook

The outlook after carpal tunnel release is very good. Most people feel much better within a few weeks and can return to normal activities. With proper care, complications are rare, and the surgery is very effective at relieving symptoms.
