NCT00789048

Brief Summary

Goal of the research

  1. 1.To check the viability of "Operating Table Position Simulating Radiographs", while positioned on the contralateral side.
  2. 2.To determine whether knowledge about the angles displayed on this radiograph (pelvic tilt) influences the accurate positioning of the acetabular cup during the Total Hip Replacement procedure.
