The purpose of this study was to analyse inter- and intra-rater reliability of the Head-Shaft angle (HSA) on radiographs from a surveillance programme for children with cerebral palsy (CP). A high HSA is a risk factor for hip displacement in children with CP. To evaluate inter- and intra-rater reliability of the HSA, hip radiographs from the CP surveillance programme CPUP in the southern part of Sweden during the first half of 2016 were included in this study.Purpose
