Fixação pedicular percutânea de fraturas vertebrais toracolombares sem compromisso neurológico

Abstract

Objective: To evaluate the efficacy and safety of percutaneous pedicle fixation in thoracolumbar fractures without neurologic compromise. Methods: The study included patients aged between 18 and 70 with AO thoracolumbar fracture type (A.3) and kyphosis >30° or reduction of vertebral body height >50% or >50% of spinal canal compromise, who underwent surgery with percutaneous pedicle fixation in the first ten days after fracture. Radiological parameters were evaluated: Cobb angle, vertebral collapse, anterior wedging and spinal canal compromise preoperatively, postoperatively and at the end of follow-up. The clinical and functional outcome was assessed by the Oswestry Disability Index (ODI
