Objective  To investigate the clinical effect of orthopedic robot-assisted sacroiliac joint screws in the treatment of posterior pelvic ring fractures. Methods  Patients who underwent sacroiliac joint screw fixation in People’s Hospital of Deyang City between January 2018 and August 2021 were included, and the patients were divided intoa robotic group and a manual group by randomization. The robot group used robot-assisted insertion of sacroiliac joint screws, and the manual group used manual insertion of sacroiliac joint screws. The general condition, time of sacroiliac joint screw placement, intraoperative fluoroscopy times, guide needle drilling times, surgical blood loss, and Majeed pelvic function score were compared between the two groups. Results  A total of 42 patients were included, and there was no significant difference in gender, age, body mass index , injury type or injury cause between the two groups (P>0.05). Finally, 21 screws were placed in 19 patients in the robotic group and 23 screws in 23 patients in the manual group. The wounds of the two groups were completely healed after operation, and there was no wound infection, iatrogenic vascular and nerve injury, and no loosening of internal fixation. There was no significant difference in screw placement time, blood loss or Majeed score between the two groups (P>0.05). The number of fluoroscopy (14.53±4.54 vs. 19.87±5.48) and drilling times (1.00±0.00 vs. 7.24±3.77) in the robotic group were less than those in the manual group, and the differences were statistically significant (P<0.05). Conclusion  Orthopedic surgical robots have the advantages of minimally invasive, less fluoroscopy, and accurate screw placement in sacroiliac joint screw placement, and have good clinical results in the treatment of pelvic fractures.
