What Is Trigger Finger?
Trigger finger (stenosing tenosynovitis) occurs when the tendon that bends a finger becomes inflamed and catches as it passes through a narrowed pulley at the base of the finger. The finger may click, catch, or lock in a bent position and need to be straightened with the other hand.
It's more common in women, people over 40, and those with diabetes or repetitive gripping activities.
Non-Surgical Treatment
- Rest and splinting: A splint keeps the finger straight, especially at night, for mild cases.
- Corticosteroid injection: First-line treatment for most cases — reduces tendon-sheath inflammation. Many resolve with one or two injections.
- NSAIDs: Help with discomfort but don't usually resolve the catching alone.
Surgery (Trigger Finger Release)
If injections fail or the finger is persistently locked, a release procedure divides the tight pulley so the tendon glides freely. Options:
- Open release: A tiny incision at the palm; very reliable.
- Percutaneous (needle) release: Done through a needle puncture in selected cases.
It's a short day-surgery procedure, usually under local anaesthesia.
Recovery
- After injection: Relief over a few days; normal use immediately.
- After surgery: Light use the same day; stitches out around day 10–14; full comfortable use over a few weeks.

Browse hand surgeons →A steroid injection typically costs S$150–S$400 plus consultation. Surgical release at a private clinic costs roughly S$2,500–S$5,000+. The surgery is medically indicated and usually Medisave-claimable up to limits.
For many people, one or two corticosteroid injections resolve trigger finger, especially when treated early. Diabetics and severe or recurrent cases respond less reliably and may need surgery.
Yes. Trigger finger release is a medically necessary procedure and is generally Medisave-claimable up to surgical limits. Confirm with the clinic.
Most people use the hand for light activities the same day and return to office work within a few days. Comfortable full use returns over a few weeks once the small wound heals.
