Ultrasonography screening for developmental dysplasia of the hip joint.

The use of ultrasonography as a complement to clinical examination will increase the reliability of the evaluation of unstable hips in newborn infants. In particular, the number of false-positive Ortolani and Barlow tests will decrease. However, the interpretation of the ultrasonogram in newborn infants has a steep learning curve with considerable risk of a high number of false-positive hips being diagnosed. Therefore, universal screening for developmental dysplasia of the hip by ultrasonography cannot yet be recommended from a cost-benefit point of view.
