Curative effects of Sextant minimally invasive percutaneous pedicle screw fixation and open pedicle screw fixation on thoracolumbar multiple spine fractures

Objective To compare the curative effects of Sextant minimally invasive percutaneous pedicle screw fixation and open pedicle screw fixation on thoracolumbar multiple spine fractures. Methods A retrospective analysis was performed on clinical data from 50 patients with thoracolumbar multiple spine fractures who were admitted to Zhengzhou Cardiovascular Hospital from January 2016 to December 2018. They were divided into minimally invasive group (28 cases) and open group (22 cases) according to surgical methods. The minimally invasive group was given Sextant minimally invasive percutaneous pedicle screw fixation, while the open group was given open pedicle screw fixation. The related indexes of surgery (operating time, intraoperative blood loss, incision length, postoperative drainage volume, hospital stay), pain status evaluated by visual analogue scale (VAS) score, vertebral function assessed by Oswestry disability index (ODI), height of vertebral anterior margin, Cobbs angle, and activity of serum creatine kinase were compared between the two groups. All patients were followed up for 6 months, and the complications were compared between the two groups. Results The intraoperative blood loss, incision length, postoperative drainage volume and hospital stay in minimally invasive group were significantly less than those in open group (all P 0.05. Conclusions Compared with open surgery, the trauma of Sextant minimally invasive percutaneous pedicle screw fixation is less for patients with thoracolumbar multiple spine fractures, which can reduce blood loss and shorten hospital stay. And it is conducive to recovery of injured vertebrae height.
