[EFFECTIVENESS EVALUATION OF PERCUTANEOUS MONOAXIAL SCREW COMBINED WITH INJURED VERTEBRAE POLYAXIAL PEDICAL SCREW FIXATION FOR TREATMENT OF THORACOLUMBAR FRACTURES].

Objective: To explore the effectiveness percutaneous monoaxial screw combined with polyaxial pedical screw for treating thoracolumbar fracture by comparing with simple polyaxial pedicle screw fixation.

Methods: Between January 2012 and June 2014, 56 cases of thoracolumbar fractures were treated by percutaneous pedicle screw fixation, the clinical data were retrospectively analyzed. Of 56 cases, 30 were treated with percutaneous monoaxial screw combined with percutaneous polyaxial pedical screw fixation (group A), 26 patients with only percutaneous polyaxial pedicle screw fixation (group B).
