Ultrasonographic Graf type IIa hip needs more consideration in newborn girls

Abstract

As Graf type IIa hip is more common, has a lower rate of spontaneous normalization and higher rate of treatment in newborn girls than in boys, we recommend paying more attention the type IIa hip in newborn girls. The rate of missing the required follow-up is unacceptably high due to parents' insensitivity regarding the type IIa hip.
