The problem

The right diagnosis, the right technique, the right hand surgeon.

Carpal tunnel syndrome is a compression of the median nerve under the transverse carpal ligament at the wrist. Numbness in the thumb, index, middle and radial ring finger, worse at night, is the classic story. Late presentations lose thenar muscle bulk and never fully recover it.

  • Is it really carpal tunnel?

    Numbness that spreads into the little finger or up the forearm can be cubital tunnel, cervical radiculopathy or brachial plexopathy. Nerve conduction studies confirm.

  • Have you tried the conservative steps?

    A neutral wrist night splint and an ultrasound-guided steroid injection give 70 per cent short-term relief. Worth a proper trial before surgery.

  • Want it done in a specialist hand unit?

    A named BSSH hand surgeon, a CQC-registered day unit, and hand therapy in the same building - so scar and pillar pain get properly addressed.

When it helps

When release is the right step - and when it is not.

The most common presentations, plus the clinical and electrophysiology findings that mean surgery is delayed, redirected, or not offered at all.

  • Moderate to severe CTS on nerve conduction

    Prolonged distal motor latency, reduced sensory amplitudes or denervation on EMG despite splinting and activity change.

  • Nocturnal numbness and tingling

    Waking most nights with pins and needles in the thumb, index, middle and radial half of the ring finger, relieved by shaking the hand.

  • Thenar wasting or weakness

    A flattened thenar eminence, weak thumb opposition or dropping cups and keys signals motor involvement. Surgery is time-critical.

  • Failed splinting or steroid injection

    A neutral wrist night splint or a 40 mg methylprednisolone injection helped briefly, then symptoms returned within weeks or months.

  • Occupational impact

    Numbness that interferes with driving, sewing, keyboard work or using tools. If the hand keeps letting you down at work, release is usually justified.

  • Pregnancy-related CTS that has not settled

    Most gestational CTS resolves after delivery. If symptoms persist beyond 6 months postpartum, release is offered on the same criteria.

  • Pillar-only pain, no nerve signs

    Aching over the base of the palm with no numbness, normal Tinel and Phalen and normal NCS. Release is not indicated. Look for tendinopathy or arthritis.

  • Red flag: neck pain and arm-wide numbness

    Numbness that spreads above the wrist, involves the little finger, or comes with neck pain suggests cervical radiculopathy or brachial plexopathy, not CTS.

Procedure options

What each option on the table actually involves - and which fits which patient. Try conservative measures first if severity is mild on NCS and there is no thenar wasting.

  • Open carpal tunnel release (OCTR)

    A 3 cm palmar incision. The transverse carpal ligament is divided under direct vision. Gold standard, cheapest, low complication rate. The workhorse in the UK.

  • Endoscopic release (ECTR)

    One or two small portals with an endoscope and hook knife. Return to work is typically 2 to 3 weeks faster, at higher upfront cost and a slightly higher transient nerve issue rate.

  • Mini-open release

    A 1.5 cm palmar incision with specialised instruments. A compromise between open and endoscopic: smaller scar than OCTR, no scope, lower kit cost than ECTR.

  • WALANT (wide-awake, no tourniquet)

    Lignocaine with adrenaline is injected into the palm. You stay awake, chatting, with no arm tourniquet, no sling and no bandage change. Walk out and use the hand the same day.

  • Local anaesthetic day case

    Standard local anaesthetic infiltration with a light arm tourniquet. Outpatient. No sedation needed for most patients. A short recovery and home within the hour.

  • Bilateral in one sitting

    Both hands released at the same visit for patients who cannot afford two recoveries. Usually WALANT, staged short breaks between sides. Increases early dependence on family.

  • Revision carpal tunnel release

    For incomplete release, symptomatic scar or recurrent CTS. Usually open with a longer incision, extended release and sometimes hypothenar fat pad interposition.

  • Second-opinion review

    A specialist review of your NCS report, symptoms and prior injection response. Sometimes the answer is another splint trial or a cervical spine MRI, not another operation.

Safety and recovery

What to expect afterwards - honestly.

Carpal tunnel release is one of the safest hand operations. The things worth planning are your anaesthesia, pillar pain during the first six months, and hand therapy from day one.

  • WALANT versus general anaesthetic

    WALANT uses lignocaine with adrenaline in the palm. You stay awake and pain-free, without a tourniquet. A brief GA is available for patients who prefer to be asleep.

  • Pillar pain for 3 to 6 months

    Tenderness at the base of the palm on either side of the scar. Common, not a complication, and usually settles by 6 months. Hand therapy speeds it up.

  • Incomplete release, roughly 3 per cent

    A retained band of transverse carpal ligament leaves symptoms unchanged. Recognised at 3 months and treated with revision release.

  • Nerve injury under 1 per cent

    Injury to the recurrent motor branch or a palmar cutaneous branch is rare in experienced hands, and part of why endoscopic release carries a small transient risk.

  • Recurrence around 5 per cent

    True recurrence years later, usually after a good initial result. Confirmed on repeat NCS and treated with revision.

  • Wound problems, 2 per cent

    Delayed healing, mild infection or a hypertrophic scar. Kept low by careful skin technique, dressing changes and hand elevation for the first 48 hours.

  • CRPS is rare but real

    Complex regional pain syndrome after hand surgery is uncommon. Early mobilisation, hand therapy and good pain control reduce the risk.

  • Realistic outcomes

    85 to 95 per cent of patients lose night pain immediately. Sensation improves over 3 to 6 months. Motor recovery is slow and often incomplete if thenar wasting has been present for over 6 months.

  • Red flags after discharge

    Spreading redness, fever, worsening pain out of proportion, or new numbness of the little finger. Call the unit or go to A and E the same day.

Reading your operation note

Your operation note in four parts. Read the last one first.

Whichever technique was used, the note the hand surgeon sends you keeps to the same shape.

A quiet reminder

Operation notes are precise and can read coldly - a plain-English explanation can help.

If anything is unclear, ask your clinician to talk you through it at your next appointment.

Frequently asked

Common questions about carpal tunnel release.

Quick answers on WALANT, open versus endoscopic, recovery, pillar pain and how quickly night symptoms settle.

  • How long does carpal tunnel release take, and will I be awake?

    The operation itself takes 15 to 20 minutes. Most UK patients now have it under WALANT, which means lignocaine with adrenaline injected into the palm. You stay awake, comfortable and chatting throughout, with no arm tourniquet. If you prefer to be asleep, a brief general anaesthetic is available. It is always a day case.

  • Open or endoscopic - which should I choose?

    Long-term outcomes are similar. Open release is the gold standard, cheapest and has the lowest complication rate. Endoscopic release usually returns you to desk work 2 to 3 weeks sooner and leaves a smaller scar, at a higher upfront cost and a slightly higher rate of transient nerve issues. If you do heavy manual work or your hand is essential to your income, it is worth weighing both with your surgeon.

  • How much does private carpal tunnel release cost in the UK?

    Roughly £2,400 to £4,500 for an open release on one hand, £3,500 to £5,500 for endoscopic release, and £4,500 to £7,500 for both hands in one sitting. A WALANT premium is £2,800 to £4,800. Nerve conduction studies and a hand surgeon consultation add £670 to £1,100.

  • How soon can I go back to work?

    Desk work: 1 to 2 weeks after open release, 3 to 7 days after endoscopic. Driving: once you can grip the wheel firmly, usually 1 to 2 weeks. Heavy manual work, tools or repeated gripping: 4 to 6 weeks. WALANT patients can use the hand for light tasks the same day, but heavy loading still waits for the ligament scar to mature.

  • Will the numbness and weakness go away?

    85 to 95 per cent of patients lose night pain the first night after surgery. Daytime numbness usually improves over 3 to 6 months as the median nerve recovers. Thenar muscle weakness recovers slowly and often incompletely if the wasting has been present for more than 6 months, which is why surgery should not be delayed once motor signs appear.

  • What is pillar pain, and is it normal?

    Pillar pain is tenderness at the base of the palm, on either side of the scar, when you press or bear weight through the hand. It is common after any carpal tunnel release, is not a complication, and usually settles between 3 and 6 months. Hand therapy scar massage and desensitisation speed it up.
