Objective   To evaluate the clinical efficacy of vertebroplasty using vertebral pedicle screw technique combined with calcium sulfate cement injection in the treatment of thoracolumbar vertebrae fractures.    Methods   Twenty-eight patients with thoracolumbar vertebrae fractures admitted in our department in recent 2 years were enrolled in this study

including 21 cases of type A

3 cases of type B

and 4 cases of type C. All patients were fixed with vertebral pedicle screw

and then verteplasty was performed using calcium sulfate cement injection.    Results   All patients were followed up for an average time of 16 months. Within the follow-up

there was no complication noted

such as loosening or breakage of internal fixation

chronical lumbar back pain

and loss of effected vertebral height. Artificial bones injected into vertebrae were absorbed in about 3 months.    Conclusion   Vertebroplasty using vertebral pedicle screw technique combined with calcium sulfate cement injection is an effective and safe procedure for thoracolumbar vertebrae fractures

which renders it possible to bear weight early and to maintain corrected vertebral height postoperatively.
