title: Evaluation of the new C-arm guiding system ClearGuide® in an orthopaedic and trauma operating theatre.
abstract: BACKGROUND
  The objective was to evaluate whether the new intraoperative C-arm guiding system ClearGuide® (CG) reduces radiation exposure of the staff in an Orthopaedic and Trauma operation theatre.
  
  
  METHODS
  Data of 95 patients CG was used were retrospectively compared using matched-pair analysis with controls without CG. Radiation dose (RD), fluoroscopic time (FT) and operation time (OT) were analysed in ten types of operative procedures.
  
  
  RESULTS
  Use of CG led to a significant reduction (p ≤ 0.05) of the RD in intramedullary nailing and plate fixation of femoral shaft fractures as well as plating of tibia shaft fractures. Concerning FT, use of CG led to a significant reduction (p ≤ 0.05) while performing kyphoplasties and plate fixation of femoral shaft fractures. Regarding OT, no statistical significance was observed.
  
  
  CONCLUSIONS
  CG as a simple, reproducible and intuitive communication tool for C-arm guidance reduces intraoperative staff radiation exposure especially while fixation of long bone fractures and in spine surgery.
