Abstract:
Objective To investigate the effectiveness of real-time tracking and virtual reality technology(RTVI)used to assist the intraoperative alignment of the trauma orthopaedic surgery robot for the treatment of femoral neck fractures and its impact on the treatment outcome.Methods A retrospective analysis was conducted on 60 patients with femoral neck fractures treated with trauma orthopedic robotic surgery from September 2020 to September 2022.Patients were divided into two groups according to whether RTVI technology was used during surgery to assist robotic surgery.There were 28 patients in the RTVI group(12 males and 16 females),with an average age of(46.2±9.3)years old ranging from 28 to 60 years old.There were 32 patients in the simple Tianji surgical robot group,including 15 males and 17 females,aged(48.2±7.8)years old ranging from 32 to 58.The number of registered fluoroscopy,operation time,total number of intraoperative fluoroscopy,intraoperative blood loss,and hospitalization time of the two groups of patients were observed and recorded.All patients received regular follow-up after surgery,and hip X-rays were routinely reviewed to record Garden alignment index,fracture healing time,postoperative complications,and Harris score.Results All 60 patients were followed up.The RTVI group was followed up for 9 to 16 months with an average of(13.0±l.2)months,and the Tianji surgical robot group alone was followed up for 10 to 14 months with an average of(12.0±1.3)months.During the follow-up period,the femoral neck fractures of both groups of patients healed well,and no complications such as internal fixation loosening and incision infection occurred.The number of registered fluoroscopy,operation time,and number of intraoperative fluoroscopy of patients in the RTVI group were significantly better than those in the simple Tianji surgical robot group(P＜0.01).There was no statistically significant difference in intraoperative blood loss,hospital stay,Garden alignment index,fracture healing time,and hip Harris score between two groups(P＞0.05).Conclusion Although RTVI technology assisted by the surgical robot for femoral neck fracture surgery has little impact on its postoperative outcome,it can effectively reduce the operating time,the number of intraoperative X-ray projections,and the risk of intraopera-tive radiation exposure to patients.It also shortened the learning curve of the operator and better reflected the precision and ef-ficiency of the trauma orthopaedic surgery robot.
