Rotator cuff tears are the most common cause of shoulder pain and disability you will encounter in clinical practice. This in-depth masterclass covers everything from the critical zone hypovascularity to complex surgical decision-making for massive tears. ⏱ Chapters 0:00 Intro 0:16 Essentials 0:50 Anatomy 1:29 Classification 2:03 Goutallier 2:33 Sits 2:56 Clinical 3:30 Imaging 4:05 Algorithm 4:40 Numbers 5:11 Clinical reasoning — Manage 5:44 Clinical reasoning — Pearls Understanding rotator cuff pathology requires appreciating the entire spectrum of disease, from partial-thickness defects to massive full-thickness tears. This comprehensive video breaks down the vital force couple biomechanics, Cofield and Goutallier classifications, targeted physical examination techniquesand imaging protocols to guide evidence-based orthopaedic management. 🦴 IN THIS VIDEO YOU'LL LEARN • How to apply the SITS mnemonic to rotator cuff anatomy and functional priorities • The biomechanical importance of the coronal and transverse plane force couples • Why the critical zone hypovascular watershed area is prone to tendon tears • How to classify tear size using the Cofield system and fatty infiltration using the Goutallier grade • How to perform targeted clinical tests including the empty can, hornblower'sand bear-hug tests • The role of MRI and radiographs in evaluating acromiohumeral distance and the tangent sign • Differentiating treatment pathways from conservative management to reverse total shoulder arthroplasty • The surgical indications for single-row, double-rowand superior capsular reconstruction • How to predict repairability based on muscle atrophy, retractionand fatty degeneration ⏱️ CHAPTERS 📌 KEY TAKEAWAYS ✔️ Superior migration of the humeral head on radiographs indicates a disrupted critical force couple. ✔️ Goutallier grades 3 and 4 predict poor surgical outcomes as advanced fatty infiltration is largely irreversible. ✔️ Massive rotator cuff tears exceed 5cm or involve two or more tendons and often require superior capsular reconstruction. ✔️ Impingement tests like Neer and Hawkins-Kennedy are sensitive but not specific for actual cuff tears. ✔️ The critical zone, a hypovascular watershed area 1cm medial to the supraspinatus insertion, is the most common tear origin. 👩⚕️ WHO THIS IS FOR This masterclass is designed for orthopaedic trainees, medical studentsand practicing clinicians seeking a comprehensive understanding of shoulder pathology, as well as curious patients wanting detailed, medically accurate information about rotator cuff conditions. 📚 RELATED TOPICS: Superior Capsular Reconstruction for Irreparable Tears · Subacromial Impingement Syndrome · Reverse Total Shoulder Arthroplasty Biomechanics · Glenohumeral Joint Osteoarthritis and Cuff Tear Arthropathy · Ellman Classification for Partial-Thickness Tears · Long Head of Biceps Tendon Pathology 🔗 More free orthopaedic teaching at Orthovellum.com — subscribe for weekly videos. 🎨 CREDITS • Original Orthovellum production. ⚠️ DISCLAIMER: Educational only — not individual medical advice.
