Abstract:
Objective To explore the clinical effect of posterior pedicle screw internal fixation in the treatment of multiple level noncontiguous thoracolumbar fractures.Methods Thirteen patients with multiple level noncontiguous thoracolumbar fractures were treated by posterior pedicle screw internal fixation.The Frankel score,percentage of vertebral compression and Cobb angle of the injured vertebral segment were analyzed to evaluate the surgery efficacy.Results All patients were followed up from 12 to 24 months ( averaged 15 months ).All cases achieved bone fusion with no implant failure.The Cobb angle of the injured vertebral segment was corrected from preoperative(22.2 ±5.3) degree to postoperative(5.3 ±3.5) degree and(6.2 ±3.6) degree at the last follow up.The percentage of vertebral compression was corrected from preoperative (45.7 ± 14.1 )％ to postoperative ( 6.1 ± 3.8 ) ％ and ( 7.2 ± 3.9 ) ％ at the last follow up.All improvements showed significant differences when compared statistically( t =15.03,t =12.05,Ps ＜0.05 ).The spinal cord function was improved 1 to 2 degree in all patients except 2 patients of grade A.Conclusion The posterior fixation with pedicle screw is a secure,safe and effective method in treating multiple level noncontiguous thoracolumbar fracture.
