Efficacy and safety of minimally invasive percutaneous surgery for treatment of thoracolumbar fracture combined with posterior ligament injury / 局解手术学杂志

ABSTRACT

Objective To investigate the efficacy and safety of the minimally invasive percutaneous surgery in the treatment of thoracolumbar fracture combined with posterior ligament injury.Methods The 94 cases of thoracolumbar fracture combined with posterior ligament injury who were admitted into our hospital from Septenber 2012 to January 2016 were selected and equally divided into the observation group and the control group(47 cases in each group) according to different methods.Patients of the observation group were treated with short segment of minimally invasive percutaneous surgery,while patients of the control group were underwent single segment of minimally invasive percutaneous surgery.Recorded the outcomes and prognosis of the two groups.Results There was no significant difference in the operation time and blood loss between the two groups(P ＞ 0.05).The postoperative volume of drainage and the length of stay in the observation group were significantly shorter than those in the control group(P ＜ 0.05).The JOA score of the observation group 1 month after operation was significantly better than that of the control group(P ＜ 0.05).The incidence of complications including pedicle screw breakage,pedicle screw loosening,incision infection,and pulmonary infection in the observation group was 4.3％,which was significantly less than 21.3％ in control group (P ＜ 0.05).The Cobb's angle of the obervation group and control group 1 month after operation were (8.55 ± 1.34) ° and (16.30 ± 2.33) ° respectively,which were significantly lower than (32.19 ± 1.98) ° and (32.08 ± 2.08) ° before operation (P ＜ 0.05).And the Cobb's angle 1 month after operation in the observation group were significantly lower than that of the control group(P ＜ 0.05).Conclusion The short segment of minimally invasive percutaneous surgery for the treatment of thoracolumbar fracture combined with posterior ligament injury can reduce the incidence of postoperative complications,promote the patient's rehabilitation,correct the kyphosis and promote the recovery of neural function,which was safer and more efficient.
