What is Trigger Finger?

Trigger Finger (stenosing tenosynovitis) is a condition in which the flexor tendon thickens and cannot glide freely through the A1 pulley. The finger "locks" in a flexed position and extends with a characteristic click or does not extend at all.

The condition affects 2-3% of the population, more commonly women aged 40-60. In diabetes, the risk increases to 10%. It may affect multiple fingers simultaneously.

Stages (Quinnell classification):

I — pain, nodule, without locking
II — click during movement, finger extends independently
III — locking, finger extends only passively (with the other hand)
IV — fixed flexion contracture

Symptoms:

Clicking during finger extension
Locking in flexed position
Painful nodule at the base of the finger on the palm
Morning stiffness, worsening after rest
Pain when gripping objects

Trigger finger: treatment options and what is known about them

The treatment plan is made by the clinic doctor after an examination and a review of your images. The table shows the options usually discussed for this diagnosis and how well they have been studied.

Option	What to expect	How well studied
Braces, splints, insoles	Offload and stabilise, reduce pain under load	Limited or conflicting evidence
Corticosteroid injection	Quickly reduces inflammation and pain, the effect is often temporary; frequent injections are undesirable	Well studied, recommended
Painkillers and NSAIDs	Ease pain during flare-ups; long-term use is limited by side effects	Moderate evidence
PRP / CGF	Concentrate from your own blood; may reduce pain, growth of new tissue has not been shown	Little data
Release of the tendon sheath	If conservative treatment does not help or there is an indication	When indicated — the doctor decides

We send your request to several partner clinics. Some will suggest conservative treatment or injections, others surgery; each clinic quotes its own conditions and price. We help you compare the options.

Regenerative methods: realistic expectations

In tendinopathies the basis of treatment is graded loading of the tendon: specific exercises over 3–6 months. Shockwave therapy helps some patients. Evidence on PRP is conflicting: there are studies showing benefit in tennis elbow and plantar fasciitis, but no convincing evidence for other tendons. Corticosteroids relieve pain quickly, but the effect is often short, and repeated injections into a tendon are undesirable.

When surgery is discussed. Surgery is discussed for a complete tendon rupture or if pain persists for more than 6–12 months despite proper treatment.

If an injection helps, the effect usually builds up over 6–12 weeks, and the result is assessed after 2–3 months. No clinic can guarantee a result.

Good to know: diagnosis, self-help, outlook

How to tell trigger finger from similar conditions

In stenosing tenosynovitis the finger catches when bending and then straightens with a click; a tender nodule can be felt in the palm at the base of the finger. The thumb and ring finger are affected most often, frequently in people with diabetes. Dupuytren’s contracture causes cords without clicking, and arthritis causes swollen finger joints. The diagnosis is made on examination; ultrasound shows the thickened pulley.

What you can do yourself

Reduce forceful and repetitive gripping and use tools with thick handles. A night splint holding the finger straight helps in mild cases. Gentle tendon-gliding exercises as recommended by a physician.

Outlook and timelines

A corticosteroid injection into the tendon sheath helps most patients; sometimes a second one is needed. If the finger keeps locking, a small operation releases the pulley, usually under local anaesthesia.

Who it is not suitable for and possible risks

Contraindications

Active infection — at the injection site or systemic, with fever.
Active cancer or ongoing chemotherapy.
Blood clotting disorders or a low platelet count. Anticoagulants are discussed with the physician.
Pregnancy and breastfeeding — the procedure is usually postponed.
A corticosteroid injection into the same area in recent weeks.
A complete tendon or ligament rupture with loss of function — surgical repair is usually needed.

Possible risks

Pain and swelling at the injection site for 1–3 days.
Bruising where blood or fat tissue is taken.
Rarely, infection. The procedure is therefore performed under sterile conditions with ultrasound or X-ray guidance.
The effect may be absent or smaller than expected.

If any of these apply to you, mention it in your request. The coordinator will check with the clinic physician whether treatment is possible. Contact a coordinator.

Scientific evidence

Studies of regenerative methods show mixed results. Clinic physicians rely on research including the following:

Catapano M et al. Effectiveness of Platelet-Rich Plasma Injections for Nonsurgical Management of Carpal Tunnel Syndrome: A Systematic Review and Meta-analysis of Randomized Controlled Trials. Arch Phys Med Rehabil, 2020.
Sheth U et al. Efficacy of autologous platelet-rich plasma use for orthopaedic indications: a meta-analysis. J Bone Joint Surg Am, 2012.

Frequently Asked Questions about Treatment of Trigger Finger

Trigger finger: can surgery be avoided?

In most cases yes: the basis is exercise and load management, sometimes shockwave therapy or injections. Only a minority of patients need surgery.

Trigger finger: do PRP and cell-based methods help?

PRP may help some patients if exercise has not worked; the evidence depends on the tendon and is limited overall. Cell-based methods are poorly studied in tendinopathies.

When can I expect a result after an injection?

If an injection helps, relief usually builds up over 6–12 weeks. The result is assessed after 2–3 months; not everyone needs a repeat procedure. No clinic can guarantee a result.

Trigger finger: when is surgery needed?

Surgery is discussed for a complete tendon rupture or if pain persists for more than 6–12 months despite proper treatment. The decision is made by the clinic doctor.

How does RegenPAS help organise treatment?

RegenPAS is a patient service centre in Munich, not a clinic. We review your images and symptoms and send a request to several partner clinics at once. Clinics that can accept you send their own conditions and price; prices differ between clinics, and you choose the option that suits you. The coordinator replies within 24 hours, and a clinic physician’s preliminary opinion follows in 1–3 business days. We then arrange the appointment, visa invitation, interpreter, transfers and accommodation. Treatment decisions are made by the clinic physician. Contact a coordinator.

What is needed for a preliminary assessment?

Your MRI (or CT, X-ray) report and the images if you have them, plus a short description of your symptoms and previous treatment. Send them via the form on the website — the assessment is free and without obligation: the coordinator replies within 24 hours, and the clinic physician’s preliminary opinion follows in 1–3 business days.

How much does treatment cost and how long do I need to stay in Munich?

The cost depends on the method, the diagnostics needed and the clinic itself: prices differ between clinics. We request offers from several clinics and send you their conditions and quotes so you can compare. Price guidance is on the treatment cost page. For an outpatient procedure, 2–3 days in Munich are usually enough: examination, procedure and follow-up visit.
