Robot\u2010aided technique has shown promising results in navigation of infra\u2010acetabular and posterior column screws placement. This study sought to further examine whether the emerging anatomical plate provided advantages over the reconstruction plate in robot\u2010aided complex acetabular fracture surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective cohort analysis comparing two internal fixation methods was conducted between September 2023 and January 2025. Specifically, 23 patients with complex acetabular fractures received robot\u2010aided Union Plate fixation (Union Plate group), while another 20 patients underwent robot\u2010aided reconstruction plate fixation (Reconstruction plate group). Intra\u2010operative plate contouring time, robot\u2010aided manipulation time, the number of channel adjustments per periarticular long screws, total operation time, blood loss, periarticular long screw placement quality, fracture reduction quality, hip joint function, and postoperative complications were compared between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>With identical robotic assistance, the Union Plate group experienced significantly shorter times for robot\u2010aided manipulation (\u221212\u2009min), intraoperative plate contouring (\u22129\u2009min), and total operation (\u221223\u2009min), along with reduced blood loss (\u2212128\u2009mL) and fewer channel adjustments of the periarticular long screws, compared to the reconstruction plate group. Both groups achieved satisfactory periarticular long screws placement, with a 95.7% perfect rate in the Union Plate group and 90.4% in the reconstruction plate group, showing no significant difference. Neither group experienced iatrogenic neurovascular injuries or screw penetration. There were also no significant differences in postoperative complications, fracture reduction quality, or hip joint function between the groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In surgery for complex acetabular fractures, the Union Plate showed superior operability and safety compared to traditional reconstruction plates.
