Developmental Dysplasia of the Hip (DDH) Masterclass: Diagnosis & Treatment

Master the complete spectrum of developmental dysplasia of the hip (DDH), from subtle acetabular dysplasia to complete dislocation. Learn the critical differences between the Ortolani and Barlow tests, Graf ultrasound classificationand age-specific management. ⏱ Chapters 0:00 Intro 0:22 Essentials 1:03 Classification 1:45 Graff 2:22 Risk Factors 2:41 Ortolani Barlow 3:07 Pavlik 3:48 Reduction 4:34 Numbers 5:14 Clinical reasoning — Newborn 5:51 Clinical reasoning — Late This orthopaedic masterclass provides a comprehensive breakdown of DDH pathophysiology, clinical assessmentand treatment algorithms. We explore why ligamentous laxity and mechanical factors like breech presentation cause a shallow acetabulumand detail exactly how to manage the condition based on the age at diagnosis—from Pavlik harness protocols in newborns to closed reductions, open reductionsand pelvic osteotomies in older infants and walking-age children. 🦴 IN THIS VIDEO YOU'LL LEARN • How to reliably perform and interpret the Ortolani and Barlow manoeuvres in newborn hip screening • The BFFF risk factors for DDH: Breech presentation, Female sex, First-bornand Family history • How to apply the Graf ultrasound classification and alpha angle to assess hip morphology objectively • The proper positioning and strict safety protocols for using a Pavlik harness in infants under six months • The specific soft tissue obstacles to reduction, including an inverted labrum and hypertrophied ligamentum teres • How to identify late presenting DDH using limited abduction and the Galeazzi sign • When to abandon a Pavlik harness to prevent 'Pavlik disease' and posterior acetabular erosion • The indications for proceeding to an examination under anaesthesia, arthrogramand hip spica casting • How to prevent the devastating complication of avascular necrosis (AVN) by avoiding forced abduction ⏱️ CHAPTERS 📌 KEY TAKEAWAYS ✔️ Ortolani reduces a dislocated hip; Barlow dislocates an unstable hip. Always feel for a clunk, not a click. ✔️ Pavlik harness is first-line for under six months, maintaining flexion (100-110°) and safe abduction (50-70°). ✔️ Avascular necrosis is the most severe complication—never force abduction during reduction or casting. ✔️ If a hip fails to reduce within 3-4 weeks of Pavlik harness wear, abandon it to prevent posterior acetabular erosion. ✔️ Limited hip abduction is the most reliable clinical sign in older infants presenting after six months of age. 👩‍⚕️ WHO THIS IS FOR This video is designed for orthopaedic trainees, medical students, junior doctorsand paediatric clinicians, as well as curious parents and patients seeking a high-yield, in-depth understanding of hip dysplasia. 📚 RELATED TOPICS: Graf ultrasound technique and alpha angle measurement · Pavlik harness complications and femoral nerve palsy · Salter innominate pelvic osteotomy for DDH · Tönnis radiographic classification in paediatric hips · Teratologic hip dislocation vs idiopathic DDH · Avascular necrosis of the femoral head in infants 🔗 More free orthopaedic teaching at Orthovellum.com — subscribe for weekly videos. 🎨 CREDITS • Original Orthovellum production. ⚠️ DISCLAIMER: Educational only — not individual medical advice.
