Background: Limping is a debilitating problem that can be prevented by screening at risk newborns. Jaundice isa problem that brings approximately one fifth of newborns to hospital in early infancy. The aim of this study wasto find out whether the newborns with physiologic jaundice are at an increased risk of developing developmentaldislocation of hip and whether it is logical to screen these newborns with Graf’s ultrasonographic method.Methods: Throughout a year, 320 icteric newborns (640 hips) that referred to Nemazee Hospital NeonatalEmergency Room for checking their bilirubin were screened by Graf’s ultrasonographic method for developmentaldislocation of hip (DDH). Any newborn with other problems such as congenital anomalies were excluded formthis study.Results: Of the 640 hips, 21 newborns (3.28%) had a dysplastic hip (Class IIa ) that needed follow up and 12from them came back for follow up of hip ultrasongraphy, all of whom became normal (Class Ia) without treatment.Only 1 hip did have severe dysplasia (Class IIc) (.16%) that needed treatment at the time of discovery.Conclusion: The rate of DDH seems not to increase in the newborns with physiologic jaundice. It seems not tobe logical to screen newborns with physiologic jaundice with Graf’s ultrasonographic method, if screening is notcost-effective.
