Introduction: Ultrasound has an established role in the detection of developmental dysplasia of the hip (DDH). Lack of uniformity in the appropriate age to perform studies in at-risk children with a normal clinical examination at birth exists. Opening a new tertiary paediatric hospital saw a variety of referral time frames for initial screening ultrasound for DDH.Methods: Literature review and retrospective clinical audit were undertaken. DDH ultrasounds of babies with the following criteria were reviewed: normal clinical examination and one or more risk factors. Patients were followed up via their electronic medical record.Results: There were 187 eligible patients: 124 (66.3%) had normal initial scans while 63 (33.7%) were recommended to have a follow-up scan. Most subnormal results (Graf 2A or lower, laxity and/or less than 50% femoral head coverage) (n = 59, 93.7%) were scanned before 6 weeks of age, only four (6.3%) presented at 5 weeks after birth or later.Discussion: This study identified a potential for reduction in follow-up studies through delayed initial ultrasound, improving from 4 to 6 weeks of age, without adverse outcomes. Early screening ultrasounds may result in overdiagnosis of DDH during the maturation process of the neonatal acetabulum, potentially causing anxiety and unnecessary follow-up.
