Trigger finger release

What is trigger finger release?

Trigger finger happens when the tendon that bends your finger or thumb struggles to glide through a snug tunnel (the A1 pulley) at the base of the digit. The finger can click, catch, or lock in a bent position and be sore, often worse in the morning.

Trigger finger release is a small operation that opens that tight tunnel so the tendon can move freely again. It can be done as open surgery through a tiny cut in the palm, or percutaneously using a needle through the skin.

Many trigger fingers settle with rest, a splint, or a steroid injection, so surgery is usually offered when those have not worked or the finger keeps locking. It treats the catching and locking; it does not treat other hand problems such as arthritis or carpal tunnel syndrome, which need their own assessment.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Steroid injection vs surgery for trigger finger

Many people try one or two injections first. Surgery is usually offered if injections do not work or the finger keeps locking.

Preparing for your procedure

• Tell your surgeon about diabetes, rheumatoid arthritis or other inflammatory conditions, as these affect healing and the chance of more fingers being involved.
• List all your medicines, including blood thinners, so the team can advise whether anything needs adjusting.
• Mention how many steroid injections the finger has already had, as several injections can make surgery slightly more likely to be needed.
• Arrange for the hand to be free of heavy use for a few days, and think about how you will manage at work.
• Wear loose sleeves so the hand and wrist are easy to access.
• You can usually eat and drink normally because it is done under local anaesthetic, but follow the clinic's specific instructions.
• Plan how you will get home; you may not be able to drive immediately afterwards.

What happens

The procedure is usually done under local anaesthetic, so you are awake but the hand is numb. You may feel pushing or pressure but should not feel pain.

For an open release, the surgeon makes a small cut in the palm at the base of the finger, finds the tight pulley and divides it, then checks the finger moves freely before closing the skin with a stitch or two. A percutaneous release uses a needle through the skin instead of a cut.

The whole thing usually takes about 15 to 30 minutes. You will have a dressing afterwards, and you can normally go home the same day and start gently moving the finger soon after.

Is this procedure right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

Comfort, sedation or contrast choices

If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.

Overall, serious problems are uncommon after trigger finger surgery, but the small nerves run very close to the tendon, so choosing a surgeon experienced in hand surgery matters, especially for the thumb and index finger. Ask how movement and stiffness will be managed afterwards and whether you will see a hand therapist.

Published figures to discuss

Trigger finger release is generally a low-risk procedure with high success, but reported rates vary with technique, surgeon experience, the digit involved and underlying conditions such as diabetes. Figures below are cautious ranges from published series and should be read as a guide, not a promise.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

Recovery is usually quick. The catching often stops immediately, but the palm can stay tender for a few weeks while the wound and deeper tissues settle, and keeping the finger moving early helps avoid stiffness.

• A tender, slightly swollen palm and scar for a few weeks
• Some stiffness first thing in the morning that eases with movement
• A scar that feels firm or sensitive when pressed, then softens
• Grip strength taking a little while to return to normal

Aftercare

• Keep the dressing clean and dry until you are told the wound can get wet.
• Move the finger gently and often from early on to prevent stiffness, as advised by your team.
• Elevate the hand in the first days to reduce swelling and throbbing.
• Take simple painkillers as needed for soreness.
• Avoid heavy gripping, lifting or repetitive hand work until your surgeon or therapist says it is safe.
• Massage the scar once healed, if advised, to keep it supple.
• Keep your follow-up appointment so healing and movement can be checked.

• Simple painkillers at home
• Time off heavy hand use arranged
• Loose sleeves for dressing changes
• A way to keep the dressing dry when washing
• Lift home arranged for the day of surgery
• Hand therapy or follow-up appointment noted
• Clinic contact number saved in case of problems

Scars and how they heal

Open release leaves a small scar in a natural crease at the base of the finger, usually about a centimetre or two long. It is often firm and tender for a few weeks and may be sensitive to direct pressure, then fades and softens over a few months. A percutaneous (needle) release usually leaves only a tiny puncture mark.

⚠ Get urgent help if…

• Spreading redness, heat or swelling around the wound
• Pus or discharge, or a wound that opens up
• Increasing rather than improving pain after the first few days
• Fever or feeling generally unwell
• New numbness, pins and needles or loss of movement in the finger
• A finger that becomes very stiff, swollen, shiny or intensely painful out of proportion to the wound

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your surgeon gives you.

Results & realistic expectations

A good result is a finger that bends and straightens without catching or locking, with the wound healing neatly. The triggering itself usually stops straight away after surgery, while soreness and grip take a few weeks to settle.

Surgery cannot guarantee a finger that feels completely normal immediately, and stiffness can take time to resolve, especially if the finger had been locking for a long time. It also does not treat other causes of hand pain, such as arthritis, which need separate assessment.

For most people, releasing the pulley gives lasting relief and the same finger does not trigger again. Recurrence after open surgery is uncommon. Some people develop trigger finger in other digits over time, particularly if they have diabetes or an inflammatory condition, and these are assessed and treated separately.

Related tests, treatments or support

If you have other hand problems being treated at the same time, such as carpal tunnel syndrome or another trigger digit, your surgeon may release more than one structure in a single procedure. This is planned with you in advance, because it can change the recovery and the amount of hand therapy you need.

Follow-up & long-term care

You will usually be seen at about one to two weeks to remove any stitches and check the wound and movement. If stiffness or tenderness is slow to settle, you may be referred to a hand therapist for exercises and scar care. Report any signs of infection or new numbness straight away rather than waiting for the appointment.

• Keep the finger moving with the exercises you are given to maintain full bend and straighten.
• Massage the healed scar if advised, to keep it supple and less sensitive.
• Manage diabetes or inflammatory conditions well, as good control may reduce the chance of further trigger fingers.

Repeat, follow-on and what comes next

• Most fingers are cured by one release and do not need further surgery.
• If triggering persists or returns, a repeat procedure or further assessment may be needed.
• Stiffness that is slow to settle is usually managed with hand therapy rather than more surgery.
• People with diabetes or inflammatory arthritis may need other digits treated over time.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

• Clear written wound-care advice and signs of infection to watch for, with a named contact route.
• Early gentle movement guidance and access to a hand therapist if stiffness develops.
• A follow-up appointment to remove stitches and check movement.
• Honest advice about when grip and full comfort are likely to return for your job and activities.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

• The surgeon's fee and whether one or more fingers are treated at the same time
• Open versus percutaneous (needle) technique
• Facility or day-case theatre fee
• Whether you have a steroid injection first as a separate step
• Hand therapy sessions if stiffness needs treating afterwards
• Follow-up appointments and stitch removal
• Whether any inflammatory condition makes the procedure more involved

• The surgeon's fee and how many fingers it covers
• The facility or theatre fee and local anaesthetic
• Dressings, stitch removal and follow-up appointments
• Any hand therapy that may be needed
• What happens, and what it costs, if triggering returns or further treatment is needed
• The cancellation policy
• What is included if a complication needs treating

On the NHS? Trigger finger surgery is often available on the NHS when simpler treatments have not worked, though local funding criteria vary; private treatment is sometimes chosen for speed or choice of surgeon.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Consent traps and marketing red flags

These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.

Choosing a specialist safely

• Check the surgeon is on the GMC Specialist Register for this area.
• Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
• You're entitled to time to consider and to have your questions answered before you agree — the surgeon who looks after you should explain it, not a salesperson.
• Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
• You're entitled to your total cost in writing — including any follow-up — before you decide.
