Trigger Finger
Quick summary
Locking or catching finger? Ultrasound-guided A1 pulley injection in Oxford — 80% resolve without surgery.
Trigger finger (stenosing tenosynovitis) is a mismatch between the flexor tendon and its A1 pulley, causing the finger to catch, click or lock, especially in the morning.
Key takeaways
- Locking or catching finger? Ultrasound-guided A1 pulley injection in Oxford — 80% resolve without surgery.
- Diagnosed with in-clinic ultrasound alongside clinical examination.
- Treated with a stepped, evidence-based plan — not one-size-fits-all injections.
- Self-referral available — no GP letter required.
Symptoms
- Clicking or locking of a finger or thumb
- Painful lump in the palm at the base of the affected digit
- Symptoms worse in the morning, easing through the day
Causes & risk factors
- Idiopathic in most cases
- Diabetes (higher recurrence rates)
- Rheumatoid arthritis
- Repetitive gripping
Who is most at risk
- Female sex, aged 40–60
- Diabetes mellitus (increased risk and reduced response to steroid)
- Rheumatoid arthritis
- Repetitive gripping occupations
Differential diagnosis
Conditions that can mimic Trigger Finger.
- Dupuytren's contracture
- Osteoarthritis of the MCP or PIP joint
- Flexor tendon rupture
- Ganglion cyst of the flexor sheath
How we diagnose Trigger Finger
Clinical. Ultrasound confirms A1 pulley thickening and rules out flexor tendon nodules, guiding accurate injection.
Treatment options
Ultrasound-guided A1 pulley injection
Precise placement between tendon and sheath resolves ~80% of cases with a single injection.
Splinting
Overnight splint reduces flexion during the healing phase.
Surgical release
For recurrent or refractory triggering — we refer within a trusted hand-surgery network.
What we look for on ultrasound
Thickened hypoechoic A1 pulley (>0.7 mm), sometimes with a hypoechoic tendon nodule proximal to the pulley.
When to seek help
Book early — persistent triggering can lead to fixed flexion contracture. Injection outcomes are best when treatment is not delayed.
Recovery timeline
Typical timeframes after diagnosis and treatment. Individual recovery varies — your clinician will personalise this plan.
- 1Day 0–3Post-injection
Mild soreness common; often triggering settles within a week.
- 2Week 1–4Full function
Return to normal use. Most single injections give lasting relief.
- 3Month 6+Follow-up
A minority need a repeat injection or referral for A1 pulley release.

How we make treatment decisions
Every recommendation at Oxford Injection Clinic is shaped by current UK guidance — including NICE recommendations for musculoskeletal pain, published NHS guidance on injection therapy, and peer-reviewed evidence from British and international MSK medicine journals. We follow a stepped-care model: accurate diagnosis first (clinical examination and diagnostic ultrasound), conservative measures where appropriate, and image-guided injection or referral only when clinically indicated. Consultant physiotherapist Bob Chandran reviews the latest MSK literature and updates our clinical protocols routinely.

Expert MSK care in Oxford
Oxford Injection Clinic is the specialist musculoskeletal service of GB Clinic Oxford, an independent physiotherapy and interventional MSK clinic based in Botley. Our consultants and advanced practitioners assess, scan and treat the full spectrum of joint, tendon, ligament and nerve problems — from acute sports injuries to long-standing arthritis. Every clinician is HCPC-registered and holds post-graduate qualifications in diagnostic ultrasound, injection therapy or advanced musculoskeletal practice.
We believe the fastest route to recovery is an accurate diagnosis on day one. That is why every consultation includes a full history, a hands-on clinical examination and, where useful, a real-time high-resolution ultrasound scan. If an ultrasound-guided injection is likely to help, we can usually perform it in the same visit — no separate trips, no waiting weeks for imaging.
Evidence-based, patient-led
Not everyone needs an injection. Our clinicians follow NICE, BOA and international best-practice guidance to decide when injections, shockwave therapy, hydrodilatation, barbotage or a structured loading programme is the right next step. Where surgery is genuinely the best option we say so, and we can refer to trusted orthopaedic and pain specialists across Oxford, London and the Thames Valley.
Patients travel to see us from Botley, Summertown, Headington, Cowley, Iffley, Abingdon, Witney, Kidlington, Bicester, Didcot, Wallingford, Wantage, Wheatley, Thame, Woodstock, Chipping Norton, Banbury, Henley-on-Thames and Reading.
