Newborn Hip Dysplasia Screening Guidelines Need Reassessment, Study Finds

The findings of a new study published in the British Journal of General Practice suggest national guidelines on newborn hip dysplasia screening need to be reassessed.

The NHS says around 1 or 2 in every 1000 babies have developmental dysplasia of the hip (DDH) that needs to be treated.

The single-centre 15-year observational cohort study assessed the value of the primary care 6- to 8-week clinical hip examination for the diagnosis of DDH.

Over the study period, there were 70,071 infants who underwent the 6- to 8-week clinical hip assessment. A total of 170 were referred, of whom, six were diagnosed with pathological DDH.

The sensitivity, specificity, positive predictive value and negative predictive value for the primary care hip assessment were 16.7%, 99.8%, 3.5% and 100.0%, respectively.

A multivariable model showed a positive Ortolani manoeuvre to be the sole independent predictor of instability at 6 to 8 weeks.

The authors say the results demonstrate the limitations of the primary care newborn hip check and support the reassessment of the national guidelines for this aspect of the Newborn and Infant Physical Examination DDH screening programme.
