Dynamic acetabular cup orientation in fast and slow walking total hip replacement patients: raw motion data, processed cup angles and statistical analyses

This dataset includes the input, raw output and processes data from a study investigating the orientation of the total hip replacement acetabular cup when implanted in the pelvis and during walking gait. The associated project aimed to understand the variation in cup orientation during gait compared to its orientation within the pelvic bone on implantation. This work is motivated by the refinement of testing protocol for total hip replacement devices and the understanding of the implications of cup implantation position during surgery. Movement data are used from two sub-groups of patients, with faster and slower self-selected walking speeds post total hip replacement. And the statistical analysis looks for any differences between in the groups in terms of dynamic orientation of the acetabular cup. Correlation analysis is also included, which illustrates the relationship between pelvic orientation measurements and acetabular cup orientations. That provide information on which aspects of dynamic cup orientation can be predicted simply from single pelvic angles and which are a more complex combination of multiple angular orientations. The data itself includes tabulated measurements from every stage of the analysis from the pelvic orientation angles, through the cup angles, to the high-level statistical outcomes.
