Episode notes
DDH Is A Spectrum With Age-Based Imaging
- Developmental dysplasia of the hip (DDH) ranges from dysplasia to dislocation caused by capsular laxity and instability.
- Diagnosis uses ultrasound early and radiographs after femoral head ossification around 4–6 months.
Epidemiology And Risk Factors
- DDH is the most common orthopedic problem in newborns with higher female predominance (6:1).
- Risk factors include first-born status, breech, family history, oligohydramnios, swaddling, and limited abduction.
Key Neonatal Hip Tests
- Use Barlow to test for a hip that is dislocatable and Ortolani to test for a reducible dislocation in infants under 3 months.
- Look for limb-length discrepancy and the Galeazzi (Gagliazzi) sign with apparent femoral shortening on the affected side.
