Surgical time, blood loss, postoperative complications, follow-up length, hospital stay and fracture healing time were recorded. Fracture reduction quality was estimated via criteria described by Matta.Fracture healing was evaluated on the pelvic radiographs at each follow-up.

The average intraoperative fluoroscopy in group A was 8.3 ± 1.5 times, while that in group B was 12.7 ± 2.0 times(P &lt; 0.001).

Tirobot‑aided screw fixation involves a learning curve. During the initial phase, the surgical time is prolonged due to unfamiliarity with the technology; however, as proficiency improves, the surgical time is significantly reduced compared to traditional freehand technique.
