Screening and Management of Developmental Dysplasia of the Hip in Newborns (2001)

There is fair evidence to include serial clinical examination of the hips by a trained clinician in the periodic health examination of all infants until they are walking independently. (level II-1 and III evidence, grade B recommendation)
There is fair evidence to exclude general ultrasound screening for DDH from the periodic health examination of infants. (level II-1 and III evidence, grade D recommendation)
There is fair evidence to exclude selective radiographic screening for DDH from the periodic health examination of high-risk infants. (level II-1 and III evidence, grade D recommendation)
There is fair evidence to exclude routine radiographic screening for DDH from the periodic health examination of high-risk infants. (level III evidence, grade D recommendation)
There is insufficient evidence to evaluate the effectiveness of abduction therapy (level III evidence; grade C recommendation), but good evidence to support a period of close observation for newborns with clinically detected DDH (level I evidence; grade A recommendation). However, there is insufficient evidence to determine the optimal duration of observation (level III evidence; grade C recommendation). (level III evidence, grade C recommendation; level I evidence, grade A recommendation)
