Explore the complete clinical picture of cubital tunnel syndrome, the second most common entrapment neuropathy of the upper limb. This orthopaedic masterclass covers ulnar nerve compression at the elbow, from pathophysiology to surgical decompression. ⏱ Chapters 0:00 Intro 0:20 Essentials 1:00 Classification 1:40 Anatomy 2:23 Compression Sites 2:57 Clinical Signs 3:44 Hand Muscles 4:24 Algorithm 5:17 Complications 5:56 Clinical reasoning — Manage 6:33 Clinical reasoning — Pearls This video provides an in-depth breakdown of cubital tunnel syndrome, detailing the anatomy of the fibro-osseous tunnel and the dynamic effects of elbow flexion on intra-neural pressure. We explore the McGowan classification system to guide management decisions, demonstrate essential clinical signs like Froment's and Wartenberg'sand compare conservative treatments against surgical interventions like in-situ decompression and anterior transposition. 🦴 IN THIS VIDEO YOU'LL LEARN • How to identify the anatomical boundaries of the cubital tunnel including Osborne's ligament and the arcade of Struthers • The dynamic pathophysiology of ulnar nerve compression and how elbow flexion increases intra-neural pressure • How to accurately grade cubital tunnel syndrome severity using the McGowan classification system • How to elicit and interpret classic motor signs of ulnar palsy including Froment's sign and Wartenberg's sign • Understanding the ulnar paradox and why clawing is paradoxically worse in low ulnar nerve lesions • The four potential sites of ulnar nerve compression around the elbow using the FOAM mnemonic • Identifying all hand muscles receiving ulnar innervation using the HALF PAD mnemonic • Differentiating between surgical indications and recognising when urgent decompression is required • Comparing surgical techniques including in-situ decompression versus anterior transposition ⏱️ CHAPTERS 📌 KEY TAKEAWAYS ✔️ Elbow flexion narrows the cubital tunnel by fifty-five percent and increases intra-neural pressure sixfold. ✔️ Froment's sign indicates adductor pollicis weakness and signals definitive motor involvement. ✔️ Conservative management is only appropriate for McGowan Grade I disease with entirely normal motor function. ✔️ Visible intrinsic muscle atrophy constitutes Grade III disease and requires urgent surgical decompression. ✔️ Motor recovery may be incomplete if surgery is delayed after the onset of muscle atrophy. 👩⚕️ WHO THIS IS FOR This masterclass is designed for orthopaedic trainees, medical students, junior doctorsand physiotherapists, as well as curious patients wanting a comprehensive understanding of their diagnosis. 📚 RELATED TOPICS: Ulnar nerve anatomy and entrapment sites · Froment's sign and Wartenberg's sign pathophysiology · McGowan grading system for nerve compression · Ulnar paradox and claw hand deformity · In-situ decompression vs anterior transposition 🔗 More free orthopaedic teaching at Orthovellum.com — subscribe for weekly videos. 🎨 CREDITS • Original Orthovellum production. ⚠️ DISCLAIMER: Educational only — not individual medical advice.
