Safety and effectiveness of percutaneous screw placement in pelvic and acetabular fractures assisted by 5G remote supervisory control of orthopedic robots
Objective To evaluate the effectiveness and safety of 5G remote control orthopedic robot-assis-ted percutaneous screw fixation for the treatment of pelvic and acetabular fractures.Methods From Mar.to Aug.2023,33 patients with pelvic and acetabular fractures who received robot-assisted percutaneous screw fixation were included.All the channel screws,76 in total,were implanted by an orthopedic robot that was remotely controlled by trauma surgeons from Beijing Jishuitan Hospital at the 5G+Orthopedic Remote Surgery Center of the National Ortho-pedic Medical Center.Of the patients,there were 21 males and 12 females,with the ages ranging from 18 to 78 years,mean 50.1 years.Injury mechanisms were road traffic injuries in 13 cases,falls from heights in 15,ground-lev-el falls in 3,and hit by heavy objects in 2.Among them,there were 19 pelvic fractures and 14 acetabular fractures.The screw insertion accuracy,incidence of intraoperative adverse events,screw planning time and actual insertion time,and incidence of complications within one week after surgery were assessed.Results Position of the implanted channel screws was excellent in 69 cases(90.8％)and good in 7 cases(9.2％),with no screw penetrating the cor-tical bone.The time from screw image acquisition to finish of insertion design was 3-8(mean 5.3)min,and the screw insertion time was 2-7(3.5)min.No adverse event occurred during the surgical procedure.Within one week after surgery,none of the patients experienced any complications such as wound infection,hematoma,loose or broken internal fixation,postoperative re-fractures,or vascular and nerve injuries.All the patients were satisfied with the sur-gical results.Conclusion The application of 5G remote control orthopedic robot technology in percutaneous screw insertion surgery for pelvic and acetabular fractures connects the operating room and the remote control center through a high-speed,low-latency 5G network,allowing surgeons to precisely control robots for surgical operations at different locations,which has significant advantages in improving surgical accuracy and safety.
