Carpal Tunnel

What is Carpal Tunnel Surgery?

Carpal tunnel surgery is a procedure designed to relieve the symptoms of carpal tunnel syndrome (CTS) by cutting the ligament across the top of the wrist bones. This ligament forms the narrow carpal tunnel, which houses tendons and the median nerve that controls some hand movements.

In CTS, swelling within the wrist compresses the median nerve, causing pain, tingling, numbness, and a weakened grip. Cutting the ligament releases this pressure, often reducing or eliminating symptoms.

While there is no single cause of CTS, risk factors include pregnancy, repetitive wrist movements or gripping, conditions that cause fluid retention such as diabetes, arthritis, and previous wrist fractures or dislocations.

How is Carpel Tunnel Surgery Performed?

Carpal tunnel surgery is performed to relieve pressure on the median nerve by dividing the transverse carpal ligament at the wrist. The procedure is typically carried out under local anaesthetic, allowing the hand to be numb while you remain awake.

A small incision is made in the palm at the base of the hand. The transverse carpal ligament is carefully released to decompress the nerve, and the skin is then closed with sutures. A sterile dressing is applied, and the hand is supported before discharge.

The procedure usually takes around 15–30 minutes and is performed as a day-case treatment.

Carpal Tunnel Surgery Aftercare & Recovery

Aftercare: A light dressing is applied following surgery and should be kept clean and dry until your first review, usually at around 10–14 days. Mild discomfort and swelling are common in the early days and can be managed with simple analgesia. Elevating the hand when resting helps reduce swelling.

Recovery: Finger movement is encouraged immediately after surgery to prevent stiffness. Most patients return to light activities within 1–2 weeks, although return to work depends on occupational demands. Driving can resume once you are comfortable, have adequate control of the hand and are no longer requiring strong analgesia.

Wound Care: The incision should be kept clean and protected until healed. Sutures may be dissolvable or removed at follow-up depending on technique. Gentle hand and finger exercises are recommended to support mobility and recovery.

What is carpal tunnel surgery?

Carpal tunnel surgery is a procedure to relieve pressure on the median nerve by cutting the transverse carpal ligament in the wrist. This helps reduce pain, numbness, tingling, and weakness in the hand caused by carpal tunnel syndrome (CTS).

‍

Who is a good candidate for carpal tunnel surgery?

Candidates are people with persistent CTS symptoms that do not improve with conservative treatments like splints, physiotherapy, or medication. Those with severe nerve compression or weakness in the hand may also benefit.

‍

How is carpal tunnel surgery performed?

The procedure is usually done under local anaesthetic and can be performed as open surgery or endoscopic (keyhole) surgery. The surgeon releases the transverse carpal ligament to relieve pressure on the median nerve.

‍

What is the difference between open and endoscopic carpal tunnel surgery?

Open surgery involves a single incision in the wrist, while endoscopic surgery uses a smaller incision and a thin camera to guide the ligament release. Endoscopic surgery may reduce scarring and recovery time.

‍

How long does recovery take after carpal tunnel surgery?

Most patients regain finger movement within a day or two and can return to light activities within 1–2 weeks. Full recovery and hand strength usually take 1–3 months.

‍

What are the risks of carpal tunnel surgery?

Risks include infection, bleeding, swelling, scar tenderness, stiffness, numbness, nerve injury, and, rarely, recurrence of CTS. Your surgeon will discuss these before your procedure.

‍

Can I drive after carpal tunnel surgery?

Driving is not recommended immediately after surgery. You should wait until you are off painkillers, can comfortably grip the steering wheel, and can perform an emergency stop safely.

‍

What aftercare is needed following carpal tunnel surgery?

Keep the incision clean and dry, wear any recommended splints or dressings, elevate your hand to reduce swelling, and perform gentle hand exercises as advised by your surgeon or physiotherapist.
