Objective To evaluate the clinical effects of computerized navigation system assisted the placement of the cannulated screw and internal fixation for the treatment of femoral neck fractures. Methods Fifty-nine patients diagnosed with femoral neck fracture and treated with cannulated screw internal fixation from January 2017 to July 2020 were selected. All the patients were divided into a navigation group (n=29) and a non-navigation group (n=30) according to whether using Medtronic computer surgical navigation system (S7) or not. The intraoperative blood loss, times of intraoperative fluoroscopy, times of guide needle drilling, total operation time, persons’ movement frequency during operation of the two groups were compared. The average angles of any two screws and the dispersion degree of the two screws with the farthest distance in the femoral neck on the postoperative anteroposterior and lateral X-ray films of the two groups were recorded and compared. Results Compared with non-navigation group, there were less intraoperative blood loss, shorter total operation time, less usages of intraoperative fluoroscopy, fewer guide needle drilling and less persons’ movement frequency during operation of the navigation group. There were statistical significances in intraoperative blood loss, total operation time, usages of intraoperative fluoroscopy, guide needle drilling and persons’ movement frequency during operation between the two groups (P<0.05). The average angles of any two screws and the dispersion degree of the two screws with the farthest distance in the femoral neck on the postoperative anteroposterior and lateral X-ray films of the navigation group were better than those in the non-navigation group (P<0.05). There were statistical significances in the above two indexes between the two groups. Conclusions It is safe and accurate to insert cannulated screws for the treatment of femoral neck fracture with the aid of the computer navigation system. It is worthy of promotion and practice.
