机器人辅助下微创治疗腰椎滑脱并腰椎间盘突出症的临床研究OA

Objective:To investigate the efficacy of robot-assisted minimally invasive treatment for lumbar spondylolisthesis(LS)combined with lumbar disc herniation(LDH).Methods:84 LS patients complicated with LDH who were treated in our hospital from January 2018 to January 2023 were selected.They were randomly divided into the control group(n=42)and the observation group(n=42)using the simple randomization method.The observation group underwent robot-assisted minimally invasive transforaminal lumbar interbody fusion(RA-MIS-TLIF),while the control group underwent minimally invasive transforaminal lumar interbody fusion with manual pedicle screw placement.The accuracy of pedicle screw placement,surgical indicators,visual analogue scale(VAS)scores,Oswestry disability index(ODI),postoperative complications,and bone fusion rates were compared between the two groups.Results:The accuracy of pedicle screw placement in the observation group was significantly higher than that in the control group(P＜0.05).The surgical time in the observation group was significantly longer than that in the control group(P＜0.05).Compared with that before surgery,VAS scores at all follow-up timepoints(immediately after surgery,6 months after surgery,and 12 months after surgery)decreased significantly in both groups(P＜0.05),but there was no statistically significant difference between the two groups at the same timepoints(P＞0.05).The ODI at medium-to long-term follow-up(12 and 24 months after surgery)decreased significantly in both groups compared to that before surgery(P＜0.05).There was no statistically significant difference in ODI between the two groups at 12 and 24 months after surgery(P＞0.05).There was no statistically significant difference in postoperative complications or bone fusion rates between the two groups(P＞0.05).Conclusion:Application of RA-MIS-TLIF in the treatment of LS complicated with LDH can improve the accuracy of pedicle screw placement.
