Objective  To compare the efficacy of percutaneous and open internal fixation with pedicle screw in treatment of patients with spinal fractures.

  Methods  A total of 60 patients with spinal fractures were divided into percutaneous group and open group, with 30 cases in each group. The perioperative indicators, score of Visual Analogue Scale (VAS), score of Numeric Rating Scale (NRS), indicators of spine vertebral body, and postoperative complications were compared between the two groups.

  Results  The intraoperative blood loss was less, postoperative bedridden time and hospital stay of the percutaneous group were significantly shorter than those of the open group (P < 0.05). The VAS and NRS scores of the percutaneous group were significantly lower than those of the open group at two weeks after operation (P < 0.05). There were no significant differences in anterior vertebral height ratio and kyphosis angle of vertebral body between the two groups at the time points of before operation, 7 days after operation and 3 months after operation (P>0.05). The incidence of complications in the percutaneous group was 6.67%, which was significantly lower than 23.33% in the open group (P < 0.05).

  Conclusion  Curative effect is similar between percutaneous and open internal fixation with pedicle screw, but percutaneous internal fixation with pedicle screw can shorten the hospital stay, reduce intraoperative blood loss, alleviate postoperative pain and reduce the incidence of complications.
