The Role of Intraoperative Navigation-assisted Channel Screw Technique in the Treatment of Pelvic Fractures

This was a multicenter, prospective, randomized, controlled study. Patients with pelvic fractures (Tile B and c) were recruited from the First Affiliated Hospital of Xi'an Jiaotong University, Xi'an Red Society Hospital and Xi'an 521 hospital, the patients were randomly divided into two groups according to the Order of admission: Experimental Group (intraoperative navigation combined with channel screw technique) and Control Group (open reduction and plate internal fixation) , the difference of operative effect between the two groups was compared by fracture reduction, channel screw position, operative time, fluoroscopy frequency, hospitalization time, hospitalization cost, recovery time and Mayo Score. Use Access 2003 to build a database and store data; use SPSS 21.0. 0 Software for statistical analysis. The entire process required the development of a standardized staff manual, and all were subject to rigorous training and examination in order to participate in the pilot, and the investigation process was supervised by the project leader.
