Choice of modality

ACR Appropriateness Criteria for hip dysplasia[1]
Age Scenario Usual appropriate initial imaging
<4 weeks Equivocal physical examination or risk factors No imaging
Physical findings of DDH Ultrasonography
4 weeks - 4 months Equivocal physical examination or risk factors Ultrasonography
4 - 6 months Concern for DDH X-ray. Ultrasonography may be appropriate[notes 2]
>6 months X-ray
  • Ultrasonography of hip dysplasia is generally the investigation of choice at up to 4 months due to limited ossification of the skeleton.[1][notes 2]
  • X-ray of hip dysplasia is generally the initial imaging of choice thereafter.[1][notes 2]
