Review status: REVIEWED against 2 sources listed above (2026-08) IS IT THIS? - reference only, to read alongside your own examination SYMPTOMS - what the patient reports (3) - Stiffness, discomfort, or worsening pain on the palm side of the finger during bending, often with a painful click [finger pain · joint pain] - The finger can lock while straightening out, or get stuck in a bent position [locking] - Onset can be gradual or sudden, and symptoms often interfere with work SIGNS - what you find (2) - A tender lump or swelling can be felt at the base of the finger on the palm crease [skin nodule] - The digit may be stuck in a flexed position, and moving it can cause pain or a snapping sensation [finger pain · joint pain · locking] TESTS (4) - Diagnosis is clinical - a finger that locks in flexion, clicks painfully, and catches on extension - Ultrasound is the preferred imaging test for this condition - Ultrasound can show the catching and clicking of the tendon dynamically during motion - Plain x-rays can exclude an occult fracture, generally making MRI or CT unnecessary IF NOT THIS - what else fits (7) - Acromegaly is on the differential - A ganglion cyst of the wrist is on the differential - A ganglion involving the tendon sheath is on the differential - Infection within the tendon sheath is on the differential - A loose body within the MCP joint is on the differential - Osteophytes on the metacarpal head are on the differential - Palmar plate dislocation is on the differential Source StatPearls "Trigger Finger" - disease-level clinical article Status traced to the source above 1. METHYLPREDNISOLONE [1st line] Adult 4-30 mg methylprednisolone acetate (with 1% lidocaine), or 5-10 mg triamcinolone acetonide using the 10 mg/mL preparation, injected into the flexor tendon sheath at the A1 pulley; single injection, may repeat once after 6-12 weeks - Single local injection Peds Congenital trigger thumb in children requires pediatric orthopedic evaluation for splinting or surgical A1 release. Source Depo-Medrone with Lidocaine SmPC section 4.2 (eMC product 1081) Why Corticosteroid sheath injection is the definitive non-surgical treatment of choice (~60-80% resolution rate), combined with nocturnal extension splinting. Caution Avoid intratendinous injection to prevent flexor tendon weakening or rupture. Transient elevation of blood glucose may occur in diabetic patients following corticosteroid injection. If 2 corticosteroid injections fail to resolve triggering, refer for surgical percutaneous or open A1 pulley release. Use the 10 mg/mL triamcinolone preparation for a short tendon sheath, not the 40 mg/mL - the stronger strength is not intended for this site.

NAPROXEN [add-on - not a substitute] Adult 250-500 mg twice daily with food PRN for local inflammation and discomfort x 7-14 days Peds Not recommended under 16 years for this indication - the product label restricts paediatric naproxen to juvenile idiopathic arthritis (10 mg/kg/day in two divided doses, child over 5 years). Use paracetamol or ibuprofen instead. Source Naproxen 500 mg Tablets SmPC section 4.2 (eMC product 2639) Why Adjunct NSAID added for symptomatic pain and inflammation relief in trigger finger; it does not mechanically release the constricted flexor tendon sheath, so it does not replace splinting, corticosteroid injection, or surgical release when needed. Caution Oral NSAIDs provide symptomatic relief but do not mechanically unlock flexor tendon sheath. Take with food to reduce gastric irritation. The weight fields are empty on purpose. The note already says naproxen is not for under-16s in this indication, but the numbers stayed behind it and the calculator went on drawing a dose for a 10 kg child. A withdrawn drug must not still have a working dose card. Egypt ORGOPROXEN 500 MG 20 TAB. ORGANOPHARMA ... 16.00 EGP (0.80/unit) NAPROSYN 500 MG 10 TAB.
