We investigated the local epidemiology of Developmental Dysplasia of the Hip (DDH), in order to define incidence, identify risk factors, and refine our policy on selective ultrasound screening. Data were recorded prospectively on all live births in the Exeter area from January 1998 to December 2008. We compared those treated for DDH with all other children. Crude odds ratios (OR) were calculated to identify potential risk factors. Logistic regression was then used to control for interactions between variables.Aims
