Master the orthopaedic management of gout, from identifying negatively birefringent needle-shaped monosodium urate crystals to deciding when surgical excision of tophi is required. Gout is the most common inflammatory arthritis in adults, triggering searing pain typically in the first MTP joint (podagra). Learn the precise pathophysiology, exam-ready mnemonics, and surgical indications essential for passing the FRCS and FRACS orthopaedic exams. This comprehensive guide covers the full spectrum of gout and crystal arthropathy for orthopaedic surgeons and medical trainees. Viewers will explore the NLRP3 inflammasome pathway, acute and chronic management protocols, and the critical distinctions between gout and pseudogout (CPPD). The video details high-yield fellowship exam content including definitive joint aspiration diagnosis, radiographic 'rat bite' erosions, and the MUSIC criteria for surgical intervention, ensuring candidates are fully prepared for both the bedside and the operating theatre. 🦴 IN THIS VIDEO YOU'LL LEARN: • Understand how hyperuricemia above 6.8 mg/dL leads to monosodium urate crystal precipitation in peripheral joints • Explain the NLRP3 inflammasome pathway and IL-1beta release triggered by macrophage phagocytosis of needle-shaped crystals • Identify negatively birefringent, needle-shaped MSU crystals as the definitive gold standard diagnosis via polarized light microscopy • Manage acute gouty arthritis with NSAIDs, colchicine, or steroids without initiating urate-lowering therapy like allopurinol • Recognise the classic radiographic appearances of gout, including punched-out erosions with overhanging edges • Differentiate between gout and pseudogout by comparing crystal morphology, birefringence, and classic joint involvement • Apply the NEEDLE and MUSIC mnemonics to accurately recall clinical features and surgical indications for the FRCS exam • Determine the exact orthopaedic surgical indications for chronic tophaceous gout, such as mechanical symptoms, ulceration, and nerve compression ⏱️ CHAPTERS: 0:00 Midnight foot explodes in pain 00:10 Uric acid passes the point 00:21 Crystals ignite the inflammasome 00:31 Crystal microscopy confirms the culprit 00:42 Stop the fire fast 00:52 Target serum urate below six 01:02 When crystals turn to tissue 01:12 NEEDLE guides gout care 📌 KEY TAKEAWAYS: ✔️ MSU crystals are needle-shaped and negatively birefringent (yellow when parallel to the polarizer). ✔️ Never start urate-lowering therapy (e.g., allopurinol) during an acute gout attack; douse the fire with NSAIDs or colchicine first. ✔️ Podagra (exquisite pain in the 1st MTP joint) is the classic hallmark presentation of gout. ✔️ Orthopaedic surgery for tophi is indicated for mechanical symptoms, skin ulceration, secondary infection, or nerve compression. ✔️ Target long-term serum urate levels below 6 mg/dL to dissolve crystals and prevent chronic tophaceous gout. 👩⚕️ WHO THIS IS FOR: This video is designed for FRCS and FRACS orthopaedic exam candidates, medical students, junior doctors, and rheumatology trainees preparing for board exams or seeking a rapid review of metabolic arthropathies. 📚 RELATED TOPICS: Pseudogout and CPPD Crystal Deposition · NLRP3 Inflammasome and Autoinflammatory Arthropathies · Total Joint Arthroplasty in Inflammatory Arthritis · Xanthine Oxidase Inhibitors and Uricosuric Agents · Carpal Tunnel Syndrome Secondary to Crystal Deposition · Differential Diagnosis of Acute Monoarthritis 🔗 More free orthopaedic teaching at Orthovellum.com — subscribe for weekly videos. 🎨 CREDITS: • Original Orthovellum production. ⚠️ DISCLAIMER: Educational only — not individual medical advice.
