Abstract: Objective  To investigate the clinical outcome differences between robotic-assisted intramedullary nailing and traditional manual surgery, and to analyze the advantages and feasibility of robotic-assisted intramedullary nail fixation in the treatment of intertrochanteric fractures in elderly patients. Methods  From December 2023 to December 2024, elderly patients with intertrochanteric fractures who underwent surgery at Department of Trauma Orthopedics, Beijing Luhe Hospital, Capital Medical University were included. Patients were divided into two groups based on the surgical method. The robotic-assisted group underwent robotic-assisted intramedullary nail fixation, while the traditional group received manual intramedullary nail fixation. Baseline data and observation indicators were collected and compared between the two groups to assess any differences. Results  There were no statistically significant differences in baseline data between the two groups (P > 0. 05). The intraoperative blood loss in the robotic-assisted group was (94. 28 ± 9. 43) mL, compared to (143. 00 ± 11. 11) mL in the traditional group (P<0. 001). The operative time in the robotic-assisted group was (53. 06 ± 9. 89) min, while in the traditional group, it was (66. 74 ± 10. 18) min (P<0. 001). The skin incision length for the main nail in the robotic-assisted group was (3. 23 ± 0. 64) cm, whereas in the traditional group, it was (4. 03 ± 0. 79) cm (P< 0. 01). Postoperative hemoglobin levels in the robotic-assisted group decreased by (12. 63 ± 4. 27) g/L, compared to (17. 29 ± 4. 32) g/L in the traditional group (P= 0. 018). At 6 months postoperatively, the Harris hip scores in the robotic-assisted group showed 30 cases of excellent, 10 good, and 3 poor outcomes, while in the traditional group, there were 22 excellent, 15 good, and 6 poor cases (P= 0. 198). Conclusion  Robotic-assisted intramedullary nailing for intertrochanteric fractures offers advantages such as minimally invasive and precise procedures, shorter operative times, and reduced blood loss. Compared to traditional surgical methods, it demonstrates certain benefits in reducing postoperative complications in elderly patients.
