Abstract：Objective To explore the application value of 3D printing and assisted reduction technology in the treatment of elderly patients with intertrochanteric femoral fractures.Methods A total of 120 elderly patients with intertrochanteric femoral fractures,treated at the People's Hospital of Yanzhou District,Jining,from January 2023 to December 2024,were included in this study.According to a random number table method,patients were divided into the observation group(60 cases treated with 3D printing-assisted intramedullary nail reduction)and the control group(60 cases treated with traditional imaging-assisted intramedullary nail reduction).The surgical-related indicators,healing time-related indicators,hip joint function,and postoperative complications were compared be-tween the two groups.Results The observation group showed significantly less intraoperative blood loss,short-er surgical time,fewer fluoroscopy times,shorter hospital stay,earlier weight-bearing time,and faster fracture heal-ing compared to the control group(P＜0.001).Before surgery,there was no significant difference in Harris scores between the two groups(P＞0.05).After surgery,the Harris scores increased in both groups,and the observation group had significantly higher Harris scores at 1 month,3 months,and 6 months post-surgery compared to the con-trol group(P＜0.001).The overall complication rate in the observation group was significantly lower than that in the control group(3.33％vs.16.67％,P＜0.05).Conclusion 3D printing and assisted reduction technology can effec-tively shorten the surgical time,reduce intraoperative blood loss,accelerate fracture healing,decrease postoperative complications,and significantly improve postoperative functional recovery in elderly patients with intertrochanteric femoral fractures.
