PERCUTANEOUS SCREW FIXATION FOR THE FRACTURES OF FEMORAL NECK WITH ASSISTED BY ISO-C2D COMPUTER NAVIGATION SYSTEM: AN EXPERIMENTAL STUDY
摘要
Abstract
Objective: To investigate the methods and application value of computer assisted orthopedic surgery system (CAOSS) in the percutaneous screw fixation for the fractures of femoral neck. Methods: Thirty femoral skeleton specimens were divided into two groups. Three cancellous screws were fixed in each of 15 fracture models with traditional standard fluoroscopy or Iso-C2D computer navigation system guidance randomly. The angle of screw deviation from cervicofemoral angle and femoral neck anteversion was accessed by calculating an index from the angles measured on the AP and lateral views of X-ray film, and the position of the screws was evaluated by direct measurement of the transverse section of femoral neck and assigned a score based on deviation from ideal screw position. The drilling attempts were documented. Results : Statistical analysis of the angle of screw deviation, screw spread within the femoral neck, and drilling attempts showed that the average screw deviation and screw spread were significantly better in the computer-assisted navigation group than in the conventional operation group ( P <0. 05). The drilling attempts in the navigation group were also lower. Conclusion: Computerized navigation can effectively assist the fixation of the cannulated screws in the treatment of femoral neck fractures, it improves the accuracy of cannu- lated screw placement and results in fewer drilling attempts.关键词
