Routine ultrasound screening for hip dysplasia in children with clubfoot is not supported

Despite the existence of guidelines for screening for developmental dysplasia of the hip (DDH), there remains controversy regarding the need for routine ultrasound screening for DDH in patients with clubfoot due to an unclear correlation between the two conditions. The purpose of this study is to determine whether ultrasound screening for DDH in this population improved the diagnostic accuracy of DDH over standard assessment for patient risk factors and physical exam. This is a retrospective cross-sectional review of infants diagnosed with idiopathic clubfoot who underwent hip ultrasounds to assess for DDH as identified by keyword search in an institutional radiological database at a tertiary care paediatric hospital. Patient demographics, risk factors for DDH, physical exam findings, and ultrasound results were recorded. Of the 120 patients who met the inclusion criteria between 2003 and 2018, 8 had hip dysplasia confirmed on ultrasound (6.7
