Abstract Objective: To explore the learning curve of orthopedic robot assisted percutaneous fixation of the sacroiliac screw in 3D mode. Methods: Clinical data of 31 patients with orthopedic “TiRobot II” assisted percutaneous fixation of the sacroiliac screw in 3D mode in Yueqing People’s Hospital from March 2021 to March 2022 were retrospective analyzed. These patients, numbered in chronological order according to the operation date, were divided into three groups: patients from N0.1 to No.10 were the early group, patients from N0.11 to No.20 were the intermediate group, and patients from N0.21 to No.31 were the late group. The three groups were
statistically analyzed according to the operation time, intraoperative bleeding volume, complications and sacroiliac screw position of patients at different stages. Results: None of the patients had postoperative orthopedic surgical robot-related complications. The mean operative time for robot-assisted sacroiliac screw placement decreased significantly with the number of surgical cases. There was significant difference between the mean operation time between the early group and middle and late period (P<0.05), but there was no significant difference in the mean operative time between the middle and late groups (P=0.278). Conclusion: The learning curve of orthopedic “TiRobot II” assisted percutaneous fixation of the sacroiliac screw in 3D mode is relatively steep in the early stage, tends to be stabilized after 10 cases. The adjuvant treatment of posterior pelvic ring fracture in 3D mode orthopedic robot assisted surgery is a safe and accurate method, which that can improve surgical accuracy and shorten operation time.
