Screening for developmental dysplasia of the hip

Screening programs relying primarily on physical examination techniques for the early detection and treatment of congenital hip abnormalities have not been as consistently successful as expected. Since the 1980s, increased attention has been given to ultrasound imaging of the hip in young infants (less than five months of age) as a possible tool for improving patient outcomes. Although ultrasound examination may not provide advantages over careful repeated physician examination for universal screening, a growing body of evidence indicates that ultrasound surveillance of mild abnormalities can reduce the need for bracing without worsening outcomes. Radiographic documentation of hip normality after the femoral nucleus of ossification has appeared (at three to five month of age) is still appropriate to rule out hip dysplasia.
