1012 Evaluation of the ‘Clicky’ Hip in the Diagnosis of Developmental Dysplasia of the Hip (DDH)

Abstract Aim Early detection of developmental dysplasia the hip (DDH) is associated with improved outcomes conservative treatment. Therefore, we aimed to evaluate use a ‘clicky’ as an indication for secondary assessment per British Society Children's Orthopaedic Surgery (BSCOS) consensus statement. Method Prospective cohort study all patients born within catchment area single tertiary centre (n = 27,731) whom underwent new-born and 6–8-week examination ultrasonographic screening hip. Multivariate odds ratios, cumulative risk difference, were calculated in relation DDH (Graf type IIb-IV that required treatment) those only abnormality on examination. Results The prevalence pathological treatment our population was 5.1/1000 live births 148). An abnormal defined by presence had sensitivity 11.5% [(95%CI6.84 14.75) 17/148)] positive predictive value 4.39% (95%CI2.82 6.77%) DDH. increase having from clicky during 6-8-week 10.1% ratio 3.84 (95%CI2.33 6.32) demonstrated significant association (p<0.001). Conclusions This has evaluated role neonatal screening. Clearly demonstrating statistical also providing important information relating predicative hip, addressing principal research need BSCOS
