Longitudinal radiographic comparison of percutaneous and open pedicle screw fixation for thoracolumbar burst fractures: A two-year follow-up study.
PURPOSE While percutaneous pedicle screw fixation (PPSF) and open pedicle screw fixation (OPSF) demonstrate comparable clinical outcomes at 1-year follow-up, the longitudinal evolution of sagittal alignment beyond one year remains poorly characterized. This study compared the longitudinal radiographic outcomes of PPSF...
