KumaFix fixation for thoracolumbar burst fractures: a prospective study on selective consecutive patientsAcknowledgments

Background Short-segment U-shaped pedicle screw fixation has been widely used to treat thoracolumbar burst fracture. Some studies reported the disadvantages of traditional U-shaped pedicle screw, which included a relatively high rate of adjacent segment degeneration and screw failure including screw pullout and breakage. The purpose of this study was to assess efficacy of open reduction and fixation using KumaFix fixation system in treatment of thoracolumbar burst fractures.
