Due to the aging society, the incidence of pyogenic spondylodiscitis is still rising. Although surgical treatment for spondylodiscitis in general is increasingly accepted, an optimal surgical strategy for treatment of pyogenic spinal infection has not yet been established. The aim of this study was to investigate the suitability of percutaneous posterior pedicle screw fixation for surgical treatment in patients with spondylodiscitis of the thoracolumbar spine.
