Unilateral short-segment pedicle screw fixation for treatment of thoracolumbar fractures / 局解手术学杂志

ABSTRACT

Objective To assess the operation results of unilateral and bilateral short-segment pedicle screw fixation combined with in-termediate screws in thoracolumbar fractures .Methods A total of 73 patients with thoracolumbar fracture were included in our study .Among the 73 patients, 48 cases were treated by bilateral short-segment pedicle screw fixation and the other 25 cases were treated by unilateral short-segment pedicle screw fixation,with a mean follow-up of 24.6 months.Surgical time,surgical blood loss,surgical draining loss,hospital stays, hospitalization cost,Cobb’s angle,kyphosis of the vertebral body ,anterior height of the fracture vertebral body ,VAS and ODI scores between the two groups were compared .Results There were significant differences in the surgical time and hospitalization cost between two groups (P0.05).Conclusion Unilateral short-segment pedicle screw fixation combined with intermediate screws can significantly correct the kyphosis and achieve the clinical effect of bilateral short -segment pedicle screw fixation technique .Meanwhile , the unilateral short-segment pedicle screw fixation technique can significantly reduce the surgical time and hospitalization cost ,which is an ef-fective method for thoracolumbar fracture .
