  "abstract": "Pelvic posterior-ring injury is a severe traumatic condition accompanied by substantial perioperative hidden blood loss (HBL). Minimally-invasive sacroiliac screw fixation is widely applied for this injury, yet postoperative anemia remains common and is predominantly caused by HBL. Whether robotic-assisted screw placement can reduce HBL in patients with posterior pelvic-ring injuries remains unclear. We retrospectively analyzed the data of 64 patients with posterior pelvic ring injury treated with sacroiliac screw fixation in our hospital from January 2020 to June 2023. Based on the use of intraoperative robot assistance during surgery, the 64 patients were divided into 2 groups. The total blood loss (TBL) and HBL were compared to analyze the difference between the 2 groups. In the robotic surgery group, TBL was 335.51 ± 31.46 mL, and the HBL was 300.96 ± 37.01 mL. In the freehand group, the TBL was 410.57 ± 54.55 mL, and the HBL was 370.34 ± 54.51 mL. The difference between the 2 groups was statistically significant (P < .001). However, there was no statistically significant difference in visible blood loss (VBL) and surgical duration between the 2 groups (P > .05). The robotic group presented a significantly smaller postoperative maximum hemoglobin drop (P < .001), whereas transfusion-related indicators were comparable between the 2 groups (P > .05). In the treatment of posterior pelvic ring injuries with sacroiliac screws, the assistance of surgical robots plays a significant role in reducing intraoperative blood loss, particularly hidden blood loss. Compared to traditional freehand screw placement, we recommend considering the incorporation of robotic assistance during surgery.",
