  "abstract": "Objective To compare the efficacy of placing sacroiliac screws under the assistance of the\"Tianji\"orthopedic robot system using two imaging guidance modes:3D fluoroscopy and 2D fluoroscopy with a C-arm X-ray during surgery. Methods A retrospective analysis of the clinical data of 47 patients with Tile B and Tile C posterior pelvic ring fractures who underwent sacroiliac screw fixation at Gansu Provincial People's Hospital from April 2022 to October 2025. Patients were divided into a 2D group(n=25)and a 3D group(n=22)based on intraoperative imaging guidance methods. Key parameters including operative time,fluoroscopy time,and guide wire adjustment frequency were recorded and compared between the two groups. Postoperative CT imaging was used to evaluate and compare the placement accuracy of screws using the Smith screw placement accuracy grading criteria. Results No significant inter-group differences were found in baseline data including age,gender and fracture classification(P>0.05). Compared with the 2D group,the 3D group had shorter surgery time and cumulative fluoroscopy time［(62.73±10.11)min vs(87.36 ± 23.56)min,t=4.754,P<0.01; (99.64 ± 3.68)min vs(115.32 ± 7.58)min,t=3.328,P<0.01］,and the differences were statistically significant. No statistically significant difference was observed in the number of guide wire adjustments between the two groups(Z=0.853,P=0.394). Both groups had their S2 screws placed accurately,while there was one case of inaccurate placement for the S1 screws in each group. Overall,the accuracy rates between the 2D and 3D groups showed no significant difference(96.00% vs 95.45%,P=1.000). None of the patients experienced serious complications like major blood vessel or nerve damage. Conclusion With the assistance of the\"Tianji\"orthopedic robot system,3D fluoroscopy guidance can significantly reduce both surgical duration and intraoperative fluoroscopy time. Both 2D and 3D fluoroscopy guidance also achieve safe and accurate placement of sacroiliac screws. Clinicians can choose based on the patient's situation and available equipment.",
