Abstract：Objective To investigate the effect and safety of robot-assisted percutaneous vertebroplasty(PVP)in the treatment of osteoporotic vertebral compression fractures(OVCF)with kyphosis.Methods A total of 114 patients with OVCF and kyphosis treated from April 2021 to March 2024 were selected as the research subjects.They were divided into the observation group(orthopedic robot-assisted PVP,n=57)and the control group(traditional X-ray fluoroscopy-assisted PVP,n=57)according to random number table method.The operation-related indexes,the anterior height of the injured vertebra,the Cobb angle of the injured vertebra,the visual analogue scale(VAS)score,and the incidence of postoperative complications were recorded and compared between the two groups before operation and at 1 d and 3 months after operation.Results The duration of operation,intraoperative blood loss,the number of intraoperative fluoroscopy and radiation dose received by operators in the observation group were shorter or less than those in the control group(P<0.01).At 1 d after operation,the anterior height of the injured vertebra was increased,while the Cobb angle of the injured vertebra was decreased in the two groups;the anterior height of the injured vertebra in the observation group was greater than that in the control group,and the Cobb angle of the injured vertebra in the observation group was smaller than that in the control group(P<0.05).At 3 months after operation,the anterior height of the injured vertebra was decreased,and the Cobb angle of the injured vertebra was increased when compared with that at 1 d after operation in both groups(P<0.05),but there was no significant difference between the two groups(P>0.05).The VAS pain scores at 1 d and 3 months after operation were significantly lower than those before operation in both groups,and the VAS scores at 3 months after operation were lower than those at 1 d after operation(P<0.05),but there was no significant difference in VAS scores between the two groups at each time point(P>0.05).The postoperative complications of the observation group was 12.28%(7/57),which was lower than 28.07%(16/57)of the control group,showing significant difference(P<0.05).Conclusion Orthopedic robot-assisted PVP shows good clinical advantages in the treatment of kyphosis after OVCF,which can reduce the intraoperative blood loss,times of intraoperative fluoroscopy and radiation dose received by operators,better restore the anterior vertebral height and Cobb Angle,and reduce the incidence of postoperative complications.
