Study on the currative effect of computer-guided percutaneous pedicle screw fixation combined with bone grafting through pedicle in the treatment of thoracolumbar fracture
Objective To analyze the efficacy of computer-guided percutaneous pedicle screw fixation combined with injured vertebral bone grafting(PPSF+BG)through pedicle in the treatment of thoracolumbar fracture.Methods The data were analyzed retrospectively of the 48 patients who undergone PPSF in the hos-pital from September 2019 to December 2021.Of them,24 underwent the computer-guided PPSF+BG,as the bone grafting group,and 24 by simple computer-guided PPSF,as the control group.The two groups were com-pared in terms of operation time,intraoperative blood loss,hospital stay,the Visual Analogue Scale(VAS)and Oswestry Disability Index(ODI),the height of the injured vertebra(anterior and posterior)and Cobb an-gle.All of them were followed up for more than 12 months,and the data were complete,and the endoplants were removed at the last follow-up.Results There were no significant differences in age,gender,length of hospital stay,AVH,cobb Angle and VAS score before and after operation between the two groups(P>0.05).There were significant differences in blood loss,operation time,VAS score at last follow-up,AVH loss between the two groups(P<0.05).Conclusion Computer-guided PPSF+BG in the treatment of thoraco-lumbar fracture reconstruct the vertebral body height very well,avoid the loss of vertebral height,and relieve the long-term pain of patients better,which had certain clinical value.
