A Comparative Analysis Of Minimally Invasive Percutaneous Pedicle Screw Fixation And Open Surgery For The Treatment Of Thoracolumbar Fractures

Objective: To comparison and analysis of minimally invasive percutaneous pedicle screw fixation and open reduction and internal fixation effect of surgical treatment for the treatment of thoracolumbar fractures. Methods: Select affiliated hospital of shandong university of TCM in October 2013- October 2015 admitted during the period of 40 patients with thoracolumbar single vertebral fracture as the research object. Experimental group 20 cases were treated by minimally invasive percutaneous puncture pedicle fixation, control group 20 cases were treated by traditional cut pedicle fixation. All the records in the two groups patients perioperative data indicators, including the operation time, intraoperative blood loss, postoperative patients with fields activity time and hospitalization days; Records of two groups of patients in the preoperative and postoperative, a month after operation, at the time of the last follow-up of wounded vertebral Cobb Angle and leading edge vertebral height; Records of two groups of patients with preoperative and postoperative 7 days, a month after operation, the VAS score of the last follow-up and Oswestry disability scores.By measuring the preoperative and postoperative wound vertebral height of vertebral body calculated height of vertebral body to restore, measure the injured vertebra in the preoperative and postoperative spinal canal encroachment of vertebral canal occupation rate. Results: Open surgery group and minimally invasive surgical operation time difference is not obvious, not statistically significant(P > 0.05); Bleeding amount of open surgery group with minimally invasive surgery group in the above activities on time and hospitalization days were comparable significant difference(P < 0.05). Group comparison: minimally invasive surgery group after one month, the last follow-up Cobb Angle compared with preoperative Cobb Angle were comparable significant difference(P < 0.05); Minimally invasive surgery group after one month, the last follow-up fanterior edge of highly significant difference compared with preoperative comparable(P < 0.05); Two groups of patients in the preoperative and postoperative one month, the last follow-up Cobb Angle difference is not obvious, not statistically significant(P > 0.05); Two groups of patients in the preoperative and postoperative one month, the comparison of the last follow-up fanterior flange height difference is not obvious, not statistically significant(P > 0.05). Group comparison: minimally invasive surgery group at the end of the week, a month after operation, postoperative followup time of VAS score and the significant difference(P < 0.01); Minimally invasive surgery group at the end of the week, a month after operation, postoperative follow-up time of Oswestry disability scores and preoperative significant difference(P < 0.01); Open surgery group with minimally invasive surgery group before surgery, postoperative follow-up a month and the last VAS score has no obvious difference is not statistically significant(P > 0.05), and postoperative week VAS score had significant difference(P < 0.05); Open surgery group and minimally invasive group no obvious difference before surgery and postoperative week Oswestry scores no statistical significance(P > 0.05), and after a month, the last follow-up differences(P < 0.05).The two groups after surgery, postoperative week vertebral body recovery rate was no significant difference(P > 0.05), after a month, the last follow-up differences(P < 0.05); Two groups of patients with preoperative and postoperative, at the end of the week, a month after operation, postoperative follow-up time spinal canal encroachment rate has no obvious difference(P > 0.05). Conclusion: Minimally invasive percutaneous pedicle screw internal fixation technology compared with open surgery with small trauma, postoperative fields activity time is short, short hospitalization days and the advantages of the rapid recovery, and postoperative wound vertebral Cobb Angle, height of injured vertebral fanterior margin recovery, recovery rate of vertebral bodies in vertebral reduction effect and no obvious difference was found between open surgery.
