Abstract:Objective: To evaluate the clinical efficacy of percutaneous pedicle screw fixation combined with self-curing calcium phosphate in intensive treatment of thoracolumbar vertebral fracture. Methods: A total of 61 patients with thoracolumbar fracture admitted between June 2019 and June 2020 were enrolled in this study. Thirty-one patients were treated with percutaneous pedicle screw fixation(simple internal fixation group), thirty patients were treated with percutaneous pedicle screw fixation combined with minimally invasive self-curing calcium phosphate for intensive treatment (internal fixation and strengthening group). All patients were followed up for 13~25 months, with an average of (15.95±0.76) months. Perioperative indicators, follow-up indicators and imaging data were compared between the two groups. Results: The operation time of simple fixation group was less than that of the internal fixation and strengthening group (P<0.05). There were no statistical significance between the two groups in incision length, intraoperative blood loss and length of hospital stay (P>0.05). There was no statistical significance in the incidence of internal fixation failure between the two groups (P>0.05). There was no statistical significance in postoperative VAS score and ODI score between the two groups (P>0.05). At the last follow-up, the VAS score and ODI score of the simple fixation group were higher than those in the internal fixation and strengthening group (P<0.05). In terms of imaging, there was no statistical significance in compression ratio of the anterior edge of the injured vertebra and sagittal Cobb Angle between the two groups (P>0.05). At the last follow-up, the compression ratio of the anterior edge of the injured vertebra loss and Cobb Angle loss in the simple fixation group were greater than those in the internal fixation and strengthening group (P<0.05). Conclusion: Percutaneous pedicle screw fixation combined with minimally invasive self-curing calcium phosphate for intensive treatment can reduce the incidence of late vertebral height loss, reduce postoperative residual lumbago, so that patients can get better function.
