Comparison of clinical results between acrossing the injured vertebra precutaneous and traditional open fixation for Magerl A thoracolumbar fractures / 实用医学杂志

ABSTRACT

Objective To compare the efficacy of acrossing the injured vertebra percutaneous pedicle screw fixation and traditional open surgery for Magerl A thoracolumbar fractures.Methods Retrospective analysis 56 patients with single segmental Magerl A thoracolumbar fractures without neurological symptoms were stabilized,including percutaneous fixation in 26 cases and open fixation in 30 cases.The operation time,intraoperative,blood loss,incision length,sagittal Cobb angle,height of injured vertebral,VAS,ODI,were compared between 2 groups.Results The precutaneous group less surgical blood loss,incision length and postoperative go to the fields time than the open group (P ＜ 0.05).There were improvements in Cobb angle and anterior height in two groups (P ＜ 0.05).The precutaneous group had lower VAS and ODI scores postoperation (P ＜ 0.05).The fracture vertebral front height and Cobb angle had significantly loss at final follow up than on the third day postoperation (P ＜ 0.05).Conclusions The percutaneous pedicle screw fixation can achieve similar effect in the treatment of Magerl A thoracolumbar fractures without neurological symptoms than open surgery,with less iatrogenic injury,less intraoperative blood loss and quick recovery for patients.
