- Abstract: Objective To investigate the therapeutic effects of proximal femoral nail antirotation(PFNA)assisted by robot navigation and PFNA guided by C-arm X-ray machine for the treatment of intertrochanteric fracture of femur(IFOF).Methods The 100 patients with unilateral IFOF in our hospital were selected as the study subjects.They were divided into the control group(50 cases)and the robot-assisted group(50 cases)according to random number table method.The control group was treated with PFNA internal fixation under C-arm X-ray machine fluoroscopy,and the robot-assisted group was treated with PFNA internal fixation assisted by robot navigation.Surgical indicators,fracture reduction and fracture healing,stress response indexes,hip joint function,quality of life score and incidence of surgery related complications were compared between the two groups.Results The operation time,total fluoroscopy time,nail placement time and fracture healing time of the robot-assisted group were shorter than those of the control group(P<0.05);and the intraoperative blood loss,guide needle adjustment frequency,and fluoroscopy frequency of the robot-assisted group were less than those of the control group(P<0.05).The fracture reduction and fracture healing in the robot-assisted group were better than those in the control group(P<0.05).Two days after operation,the levels of serum norepinephrine(NE),angiotensin Ⅱ(Ang Ⅱ)and superoxide dismutase(SOD)in the two groups were higher than those before operation(P<0.05),and the levels of serum NE,Ang Ⅱ and SOD in the robot-assisted group were lower than those in the control group(P<0.05).The Harris score and 36-item short-form(SF-36)score of patients 7 days and 3 months after surgery in the two groups were higher than those before surgery(P<0.05),and the above scores 3 months after surgery were higher than those 7 days after surgery(P<0.05).Harris score and SF-36 score 7 days and 3 months after operation in the robot-assisted group were higher than those in the control group(P<0.05).The incidence of complications in the robot-assisted group was lower than that in the control group(P<0.05).Conclusion Compared with the C-arm X-ray machine fluoroscopy,the treatment of IFOF with PFNA assisted by robot navigation can further shorten the operation time,reduce the surgical trauma and the incidence of complications,achieve better effect of fracture reduction and healing,reduce stress response of the body,and improve hip joint function and quality of life for patients.
