Analysis of therapeutic effect of robot-assisted percutaneous screw in the treatment of thoracolumbar fractur
Objective To explore the clinical effect of PSIS-A robot-assisted percutaneous screw in the treatment of thoracolumbar fracture.Methods Patients with thoracolumbar fracture who were hospitalized in Mianyang Orthopedic Hospital between August 2022 and January 2024 and required percutaneous pedicle screw f ixation were selected.Patients were divided into robot group and free hand group by random number table.Operative time,intraoperative bleeding,intraoperative radiation dose and time,implant accuracy rate,small joint invasion rate,Visual Analogue Scale score for pain and other indexes were compared between the two groups.Results A total of 60 patients were included.Among them,there were 28 cases in the robot group and 32 cases in the free hand group.On the third day after surgery,the Visual Analogue Scale score of the robot group was better than that of the free hand group(P=0.003).Except for intraoperative bleeding and radiation frequency(P＞0.05),the surgical time,average nail implantation time,and intraoperative radiation dose in the robot group were all lower than those in the free hand group(P＜0.05).The accuracy and excellence rate of nail planting in the robot group were higher than those in the free hand group(94.6％vs.84.9％;x2=7.806,P=0.005).There was no statistically significant difference in the acceptable accuracy rate(96.4％vs.91.1％;x2=3.240,P=0.072)and the incidence of screw facet joint invasion(7.2％vs.14.1％;x2=3.608,P=0.058)between the two groups.Conclusion The application of PSIS-A type robot assisted percutaneous minimally invasive pedicle screw fixation in the treatment of thoracolumbar fr actures is promising.
