To investigate the short-term effectiveness and advantages of the orthopedic robot-assisted femoral neck system (FNS) fixation in the treatment of fresh femoral neck fractures compared with the traditional manual operation. A clinical data of 74 patients with fresh femoral neck fractures, who had undergone internal fixation with FNS between April 2020 and September 2021, was retrospectively analyzed. Among them, there were 31 cases of TiRobot-assisted operation (trial group) and 43 cases of traditional manual operation (control group). There was no significant difference between groups ( P>0.05) in terms of gender, age, cause of injury, time from injury to operation, fracture side and type. The fracture fixation time (intraoperative fracture reduction to the end of suture), invasive fixation time (incision of internal fixation to the end of suture), the number of placing key-guide needle, incision length, intraoperative blood loss, fracture healing, and Harris score of hip function were recorded and compared. All operations were performed with no neurovascular injury or incision complications. The invasive fixation time, intraoperative blood loss, the number of placing key-guide needle, and the incision length in the trial group were superior to the control group ( P<0.05), and there was no significant difference in fracture fixation time between groups ( P>0.05). All patients were followed up 4-16 months (mean, 7 months). The fracture did not heal in 1 patient of trial group, and the other fractures healed in 2 groups; the fracture healing time was (17.6±1.9) weeks in trial group and (18.2±1.9) weeks in control group, and there was no significant difference between groups ( t=0.957, P=0.345). At last follow-up, the Harris score of the trial group was 82.4±5.8, which was higher than that of the control group (79.0±7.7), but the difference was not significant ( t=-1.483, P=0.147). Orthopedic robot-assisted FNS fixation in the treatment of fresh femoral neck fractures has the similar short-term effectiveness as the traditional method, but the former has advantages in terms of operation time, intraoperative blood loss, and the number of placing key-guide needle, making the operation more minimally invasive and quicker, and more suitable for older patients.
