Impact of endplate facture on prognosis of thoracolumbar fracture / 中国矫形外科杂志

ABSTRACT

[Objective]To investigate the impact of endplate facture on prognosis of thoracolumbar fracture.[Method]Seventy-three patients with thoracolumbar fractures were treated with transpedicular bone grafting combined with pedicle screw fixation system.Of them,thirty-four cases eligible for the study were divided into groups A and B.Group Ano endplate fracture or minor endplate fracture.Group Bbursting endplate fracture.The height of fractured vertebra and the Cobb angle before and after operation,and at the final follow-up were determined and analysed.[Result]There were no significant differences in Cobb angles and height between growps A and B before operation.After operation,the height of fractured vertebra in group B were lower than that of group A.The Cobb angles had no significant difference between the two groups.The height and Cobb angles between the two groups had significant difference at final follow-up.The improvement in group A was significant higher than in group B.[Conclusion]Endplate bursting facture affects the reduction of fractured vertebra and causes loss of the vertebral height and the corrected angle.
