MSK: Trigger Finger: Free MSRA Podcast

🎧 MSRA Podcast: Trigger Finger – When Tendons Get Stuck🖐️ MSK Deep Dive | High-Yield for the MSRAEver felt your finger lock, catch, or click when you move it? 🎯 In this episode, we break down Trigger Finger (stenosing tenosynovitis) — a small mechanical problem with big day-to-day consequences. Ideal for MSRA prep or practical knowledge in clinic.🧠 What Is Trigger Finger?Inflammation causes thickening of the tendon or sheath, leading to a mismatch in size at the A1 pulley.🎢 This causes a snapping or locking sensation when the finger moves — it might get stuck and then suddenly pop free.📌 Causes & Risk Factors• Repetitive hand movements (e.g. gripping tools)• Rheumatoid arthritis• Diabetes mellitus• Age >40• Female sex• History of hand trauma• Anatomical variations⚙️ PathophysiologyThink of the tendon as a rope, sliding through a tunnel.🪤 A nodule (speed bump) on the tendon catches at the pulley entrance → snap, click, or lock.🩺 Symptoms• Pain/tenderness at base of the finger or thumb• Stiffness, worse in the morning• Audible/palpable clicking• Finger may lock in flexion• Often affects thumb, middle, or ring finger• May feel a palpable nodule over the A1 pulley🔍 Differential Diagnosis🧐 Don’t confuse it with:• Osteoarthritis• Dupuytren’s contracture• Flexor tendinitis• Ganglion cyst near tendon• Nerve compression📊 Epidemiology✅ Affects ~2–3% of the UK population✅ More common in women >40✅ Associated with systemic inflammatory diseases (RA, diabetes)🧪 Diagnosis• Clinical diagnosis based on history + exam• No imaging usually required• Ultrasound/MRI only if diagnosis uncertain💉 Management Options1️⃣ Conservative First-Line• Rest• Ice• Splinting (especially at night)• NSAIDs• Hand therapy2️⃣ Corticosteroid Injection• Injected into the flexor sheath at the A1 pulley• Often very effective – relief within days to weeks• Can be repeated if needed3️⃣ Surgical Release• Minor procedure under local anaesthetic• Cuts the tight pulley to allow smooth tendon glide• Reserved for refractory or severe cases🧠 Prognosis👍 Good with early treatment🔁 Recurrence possible if underlying causes persist⚠️ Untreated = risk of permanent stiffness and functional impairment📚 MSRA Revision Resources📄 Revision Notes:https://www.passthemsra.com/topic/trigger-finger-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/trigger-finger-flashcards/📖 Q&A Accordion Notes:https://www.passthemsra.com/topic/trigger-finger-accordion-qa-notes/🧪 Rapid Quiz:https://www.passthemsra.com/topic/trigger-finger-rapid-quiz/🎯 MSRA Quiz Bank:https://www.passthemsra.com/quizzes/trigger-finger/📘 Full MSK Course:https://www.passthemsra.com/courses/msk-for-the-msra/🎙️ A great example of a mechanical problem with a straightforward clinical solution — and a high-yield topic for your MSRA revision.#MSRA #TriggerFinger #MSRARevision #PassTheMSRA #MSK #MSRAFlashcards #MSRAQandANotes #MSRAQuiz #MSRAQuestionBank #Tenosynovitis #ClickingFinger #StenosingTenosynovitis #MSRAExam #NICEGuidelines
