Comparative Study Of Minimal—invasive Percutaneous Pedicle Screw Fixation And Open Surgery In The Treatment Of Thoracolumbar Fractures

Objective:To compare the clinical outcomes of minimally invasive percutaneous pedicle screw fixation versus open surgery in the treatment of thoracolumbar fracture.Methods:A retrospective study of patients who had undergone surgery for thoracolumbar fracture from June 2014 to December 2014 was performed.Sixty-one cases were included and 29 cases were treated by minimally invasive percutaneous pedicle screw fixation and 32 cases were treated by the traditional open pedicle screw fixation.The differences in the total length of the incision,intraoperative fluoroscopy times,operative time,blood loss,the preoperative and postoperative visual analogue scale(VAS),postoperative off-bed time and hospital stay were compared.And the preoperative and postoperative anterior vertebral body height and Coobb’s angle of the kyphosis were also compared.Results:Compared with the open group,the total length of incision was smaller and intraoperative blood loss was less,off-bed time and hospital stay were shorter,and pain of the wound was lighter in the minimally invasive group.Postoperatively,the anterior vertebral body height was retorted and the Cobb’s angle of the kyphosis was corrected obviously in both groups.But no significant difference in the imaging results was found between the two groups(P>0.05).Conclusion:Minimally invasive percutaneous pedicle screw fixation has the similar fixation efficacy with open surgery in thoracolumbar fracture.However,it can avoid extensive muscle stripping,and reduce the surgical incision,operative time,postoperative pain,off-bed time and hospital stay significantly.According to the clinical efficacy,it’s worthy of clinical application and promotion.
