| Objective:The data that asses the preoperative and postoperative vertebral body reduction and kyphosis correction are collected,as well as perioperative related indexes,in the treatment of thoracolumbar fractures without nerve injury symptoms by robot-assisted.To verify percutaneous robot-assisted minimally invasive pedicle screw placement is a suitable and effective surgical procedure for the treatment of thoracolumbar fractures.Methods:The data include of 49 patients who underwent surgical treatment for single-segment thoracolumbar fractures without nerve injury symptoms in my hospital from May 2016 to December 2020 were collected.The robot-assisted group’s.hospitalized date records from February 2018 to March 2021,and the conventional open,group’s time was from May 2016 to November 2019.We define the robot-assisted group as group A and the conventional open group as group B.There are 24 patients in group A and 25 patients in group B.Recording and comparing the two groups of patients’ numerical value,that include the PAHC,Cobb angle and LKA angle before surgery,within one week after surgery,in the first follow-up after surgery and the last follow-up,pain scores before surgery,within one week after surgery,and at last follow-up hospitalization time,operation time,as well as postoperative and perioperative laboratory indicators of the two groups of patients.Results:The operations of the patients in both groups A and B were successfully completed,and the routine follow-up of groups A was 17.21±6.30 months,as well as the B groups follow-up being 17.24±4.90 months,with an average of no postoperative complications such as screw dislocation and wound inection.The PAHC,Cobb angles and the LKA angle of the two groups of patients at each follow-up time,was significantly improved compared with that before operation,with statistical significance（P<0.05）,but there was no significant difference in PAHC,Cobb angle and LKA angle between the two groups at any follow-up time after operation（P>0.05）.There was no significant difference between the two groups in terms of operative duration.（9.71±3.38 vs 10.60±2.43）and hospital stay（132.50±45.90 vs 119.00±36.91）（P>0.05）,but the hospitalization time in the robotic group was shorter than that in the conventional open group,while the two groups of patients laboratory indicators before and after surgery including ALB（42.09±2.66 vs 42.21±3.15,37.40±3.28 vs 36.57±3.17）.HB（132.44±10.04 vs 134.78±18.75,118.75±10.40 vs 120.17±18.60）,WBC（7.59±1.75 vs 7.56±2.50,10.20±2.95 vs 10.09±2.76）and NEUT（71.93±12.40 vs 75.24±8.26,81.96±4.25 vs 83.18±5.65）were not significantly different（P>0.05）,but by comparing the preoperative and postoperative differences between ALB and HB,we found that the robot group was better than the conventional group,and the postoperative mean ALB of the robot group（37.40±3.28）was higher than that of the conventional open group（36.57±3.17）.In terms of pain scores,there was no significant difference in the VAS score and ODI score between the two groups preoperatively and at the last follow-up,but the VAS score of the two groups of patients at the one-week follow-up after surgery（3.17±1.09 vs 4.16±1.52.1,P<0.05）.ODI score（41.58%±4.17%vs 47.52%±3.48%,P<0.001）,the robotic group had a significant improvement compared with the incision group.The difference was statistically significant.Conclusion:For thoracolumbar fractures without symptoms of nerve injury.both the surgical procedures of robot-assisted percutaneous,screw placement and conventional and open screw placement can achieve good results in vert ebral reduction and kyphosis correction,but the robot-assisted group is better than conventional open group Not only is it more advantageous in terms of safety and accuracy,but also it is less trauma of the patient,which is more conducive to the early recovery of the patient and the return to normal life.Therefore,the robot-assisted percutaneous screw technique is an appropriate and efficient treatment modality to treat thoracolumbar fractures without nerve damage symptoms. |
