Objective: To evaluate the short-term outcomes of TiRobot-assisted versus conventional closed re-duction and internal fixation with PFN-A for the treatment of intertrochanteric femoral fracture. Methods: Twentypatients were enrolled into the study between November 2017 and June 2018 and were divided into orthopedic robotgroup（OR group） and conventional surgery group（CS group）

with 10 patients in each group. Intraoperative X-rayfluoroscopy time

times of fluoroscopy

time of operation

intraoperative blood loss

time to fracture healing

post-operative complications after internal fixation

postoperative tip-apex distance

and Harris Hip Score at last fol-low-up were recorded for the two groups. Results: There were no significant differences between the two groups insex

age

body mass index

and type of fracture（P > 0.05）

indicating the comparability between the two groups.The OR group had significantly less time of operation

intraoperative blood loss

X-ray fluoroscopy time

and timesof fluoroscopy（P < 0.05）

as well as a significantly larger postoperative tip-apex distance（17.7 ± 5.5 mm vs 16.5 ±4.7 mm

t = 2.313

P < 0.05）

as compared with the CS group. Neither group had complications. Conclusion: TiRo-bot navigation and positioning system-assisted closed reduction and internal fixation with PFN-A significantly im-proves the surgical accuracy in the treatment of intertrochanteric femoral fracture

and has certain advantages in re-ducing intraoperative X-ray damage and intraoperative injury and shortening the time of screw placement.
