Trigger finger, medically known as stenosing tenosynovitis, is a condition where one of your fingers gets stuck in a bent position and may suddenly straighten with a snap — like a trigger being pulled and released.
This happens when inflammation narrows the tendon sheath, restricting the smooth movement of the tendon responsible for finger flexion.
– Finger stiffness, especially in the morning
– A popping or clicking sensation during finger movement
– Tenderness or a small lump at the base of the affected finger
– Finger locking in a bent position, followed by a sudden straightening
– Repetitive gripping or hand use
– Diabetes mellitus
– Rheumatoid arthritis
– Age (common between 40–60 years)
– Gender (more common in women)
1. Non-Operative Treatments:
– Rest & Activity Modification: Avoid repetitive gripping or pinching tasks.
– Splinting: Immobilises the affected finger, allowing inflammation to settle.
> Evidence: Splinting is effective in early and mild cases. (Tarbhai et al., 2012)
2. Steroid Injection:
– A corticosteroid injection into the tendon sheath reduces inflammation.
– Effectiveness: 60–90% symptom resolution after the first injection.
> Reference: Fleisch et al., 2007
3. Platelet-Rich Plasma (PRP) Injection:
– PRP is an autologous blood-derived treatment rich in healing platelets.
– It aims to reduce inflammation and stimulate tendon healing.
– Ideal for patients who prefer biological therapy or do not respond well to steroids.
> Reference: Lee et al., 2020
4. Surgical Treatment:
– Indicated when conservative options fail.
– The procedure involves releasing the A1 pulley, allowing smooth tendon motion.
– Success rate: 95–100%. Recovery is often quick and uncomplicated.

| Treatment Option | Evidence-Based Summary |
|—————————-|—————————————————————–|
| Splinting | Effective for mild cases and early intervention (Tarbhai et al., 2012) |
| Steroid Injections | Strong first-line treatment with high success rates (Fleisch et al., 2007) |
| PRP Injections | Promising biological option; fewer systemic side effects (Lee et al., 2020) |
| Surgical Release | High success rate, low complication rate (Ryzewicz & Wolf, 2006) |
Your treatment should be based on:
✅ The severity of your symptoms
✅ Your medical history
✅ Your preferences — including interest in biological treatments
Discuss these options with your doctor to decide what’s best for you.
