The femoral necks were fixed using three cannulated screws with robot assistance applying the following procedure: image acquisition, path planning, and needle and screw placement. The results of the treatment, including operation duration, frequency of fluoroscopy use, implant placement accuracy, intraoperative bleeding, total drilling, surgical complications, fracture healing time, fracture healing rate, and Harris scores at the last follow\u2010up, were recorded and compared with 23 similar patients who underwent conventional manual positioning surgery.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 147 cannulated screws were placed in all patients. The TiRobot group had shorter operation duration (62.6 \u00b1 8.7 min\n vs<\/jats:italic>\n 72.4 \u00b1 10.3 min) and fracture healing time (5.1 \u00b1 2.4 months\n vs<\/jats:italic>\n 5.9 \u00b1 2.8 months) than the conventional group (\n P<\/jats:italic>\n > 0.05). The robot group had significantly less use of fluoroscopy (26.5 \u00b1 7.4 times\n vs<\/jats:italic>\n 51.3 \u00b1 9.4 times), intraoperative bleeding (8.2 \u00b1 5.3 mL\n vs<\/jats:italic>\n 36.4 \u00b1 12.5 mL), and total drilling (9.4 \u00b1 4.2 times\n vs<\/jats:italic>\n 18.3 \u00b1 9.1 times) than the conventional group (all\n P<\/jats:italic>\n < 0.05). The screw parallelism was significantly improved (24.0 \u00b1 0.6 points\n vs<\/jats:italic>\n 21.5 \u00b1 1.2 points) and the neck\u2010width coverage (72.0 \u00b1 6.7 mm\n 2<\/jats:sup>\n vs<\/jats:italic>\n 53.8 \u00b1 10.4 mm\n 2<\/jats:sup>\n ) was significantly enlarged compared to the conventional group (\n P <<\/jats:italic>\n 0.05). Only three guiding needles were used to penetrate the femoral head during manual insertion in the TiRobot group, which was significantly lower than that in the conventional group (3\/78, 3.8%\n vs<\/jats:italic>\n 9\/69, 13.0%;\n P <<\/jats:italic>\n 0.05). Other complications such as wound infection, vascular or nerve injury, screw loosening, and secondary screw displacement, did not occur in the two groups. There was no significant difference between the two groups in fracture healing rate (88.4%\n vs<\/jats:italic>\n 82.6%) and Harris scores at the last follow up (88.2 \u00b1 3.6 points\n vs<\/jats:italic>\n 87.3 \u00b1 4.7 points;\n P<\/jats:italic>\n > 0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n TiRobot\u2010assisted percutaneous cannulated screw fixation of femoral neck fractures is advantageous over conventional surgery with manual positioning due to easier manipulation, more accurate screw insertion, less invasion, and less radiation exposure, suggesting that it is a better method to stabilize femoral neck fractures.<\/jats:p>\n
