Trigger finger release: what the operation involves and how recovery goes

In trigger finger the tendon that bends the digit thickens or the tunnel it slides through narrows, so the finger catches and may lock bent. It can be painful and awkward, but it is rarely harmful to the hand. That is why the NHS emphasises that it can settle without treatment and treats surgery as the final step.

A reasonable trigger for surgery is a finger that keeps locking despite a splint and an injection, or one that stays stuck bent so that gripping, dressing or work are hard. If your symptoms are mild and not interfering with daily life, waiting is a legitimate choice, and your GP can advise you on when to revisit it.

The NHS page sets out four routes in sequence: anti-inflammatory medicines for pain, splinting to keep the finger straight and reduce movement, steroid injections into the finger or thumb to reduce swelling and pain, and surgery to help the digit move properly.

The retrieved pages do not give success rates for the injection or for how long relief lasts, so it is worth asking your clinician what has happened for other people with a similar problem and what you would do if the symptoms came back.

The leaflets consulted do not specify fasting rules or the anaesthetic for this operation, and these vary by hospital and by whether you have local or another type of anaesthetic. Your pre-assessment letter is the authority; follow its instructions on food, drink and medicines.

Practical preparation matters more than usual for a hand operation. Remove rings from the hand and neighbouring fingers before swelling develops, think about which tasks at home and work need two hands, and arrange help for the first days if you live alone.

The operation releases the tight section of the tendon sheath so the tendon glides again. Technique differs between surgeons, so ask which approach will be used for you and where the scar will sit.

The wound is closed with stitches, a dressing is applied, and the Wigan leaflet describes using the hand for light activity as comfort allows once you are home. It also says you should not drive until the stitches have come out and the wound has healed, and that you must then be sure you have enough strength and control.

The Wigan leaflet describes some discomfort and swelling as normal after surgery and says to contact the team for persistent pain, swelling or scar sensitivity, significant stiffness in the wrist or fingers, a finger that will not straighten fully, or difficulty using the hand for daily tasks.

Other recognised risks of any hand operation include infection, a tender scar, and rarely injury to a small nerve, but the pages retrieved did not quantify these, so no figures appear here. Ask your surgeon for numbers specific to their practice.

The Wigan leaflet recommends light use as comfort allows, scar massage once the wound is healed and dry, and tendon-gliding exercises. Scar care means unscented moisturising cream with gentle pressure along the scar 3 to 4 times a day for a few minutes each time. If the scar is over-sensitive, it suggests touching it with different textures to desensitise it.

Redness spreading from the wound, discharge, fever or pain that is rising rather than easing should be reported promptly to the hospital team or your GP, or to NHS 111 when those are closed. A finger that turns pale, blue or cold, or that loses feeling, needs urgent assessment the same day. Chest pain or breathlessness is a 999 matter.

• Is another injection a sensible option before surgery for me?

• Will the operation be under local anaesthetic, and will I be awake?

• Which technique will you use, and where will the scar be?

• When will my stitches come out and who will do it?

• Which exercises should I begin, and who will review my progress?

Some NHS areas apply local funding criteria about when trigger finger surgery is offered. Private providers usually do not apply those rules, but you would be paying or using insurance. Either way, the operation itself is similar. Ask who provides hand therapy afterwards, since a therapist-led exercise plan is what the leaflets lean on.
