Abstract: Objective To investigate the clinical effect of traumatic orthopedic robot assisting proximal femoral nail antirotation(PFNA) internal fixation for intertrochanteric fracture in the elderly patients. Methods A total of 43 elderly patients with femoral intertrochanteric fracture receiving the treatment of PFNA internal fixation in Nanchang County People's Hospital from September 2020 to September 2021 were selected.According to the surgical methods, the patients were divided into the robot group(n=21,receiving the treatment of PFNA internal fixation assisted by traumatic orthopedic robot) and the freehand group(n=22,receiving the treatment of traditional PFNA internal fixation). The fluoroscopy frequency, operation time, the volume of intraoperative blood loss, the puncturing times of guiding needle, and Harris hip score 3 months after operation were compared between the two groups. Results The fluoroscopy frequency, operation time, the volume of intraoperative blood loss, and the puncturing times of guiding needle in the robot group were lower than those in the freehand group(all P<0.01). Three months after surgery, the excellent rate of Harris hip score was 81.0% in the robot group, compared with 45.5% in the freehand group(P<0.05). Conclusions Applying traumatic orthopaedic robot to assist PFNA internal fixation in the elderly patients with femoral intertrochanteric fracture shows advantages in accurately locating the opening position, reducing the times of guiding needle adjustment and intraoperative fluoroscopy, shortening operation time, reducing intraoperative bleeding and improving the postoperative hip function of the patients.
