Abstract:
[Objective]To assess the clinical outcome of pedicle screw fixation plus bone graft of vertebral body via pedicle for thoracolumbar fractures.[Method]Ninety-six patients treated from 2003-2007 were reviewed.Twenty-eight were treated by short segment fixation(group1).Sixty-eight were treated by short-segment pedicle instrumentation combined with trans-pedicular intracorporeal bone grafting and fixation at the level of the fracture(38 artificial bone as group 2,30 autogenous bone as group 3).Preoperative TLISS(thoracolumbar injury severity score) was evaluated.Radiological evaluation was made for measuring Cobb′s angle,the percentage of the anterior and posterior height of injured vertebra and SI after operation and during the follow-up.[Result]All the patients achieved fracture union during the follow-up with a mean period of 16.8 months(range 12-20 months).All of the fractures were reduced satisfactorily.The height of the injured vertebra,Cobb′s angle correctivity were better in group 2 and 3.There was no difference between those of group 2 and 3.[Conclusion]Short segment plus fracture vertebral segmental fixation can restore the height of vetebra.It is an effcient method for thoracolumbar fracture.
