Low incidence of early developmental dysplasia of the hip in universal ultrasonographic screening of newborns: analysis and evaluation of risk factors

摘要

Purpose Different timing and approaches to screening for developmental dysplasia of the hip (DDH) are used in the orthopaedic community. Thus ultrasonographic screening programs and reports based on clinical examinations produced differing incidence rates of DDH. Furthermore different risk factors and a change of incidence of DDH in the last decades were discussed. The purpose of this study was the evaluation of incidence and risk factors of the very early DDH in a modern cohort based on a universal ultrasound screening program.
