ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of posterior short-segment pedicle screw fixation combined reduction of central end-plate by end-plate expand clamp and vertebroplasty with calcium phosphate cement for the treatment of thoracolumbar burst fractures.</p><p><b>METHODS</b>Thirty patients with thoracolumbar burst fractures were treated with posterior pedicle screw fixation combined reduction of central end-plate by end-plate expand clamp and vertebroplasty with calcium phosphate cement. There were 22 males and 8 females with an average of 47 years (range from 25 to 71 years). Segment of fracture had 1 case in T11, 5 in T12, 14 in L1, 8 in L2, 2 in L3, 1 in L4, 1 in L5. According to Denis typing, 4 cases were type A, 25 type B, 1 type C, 1 type D, 1 type E. The relative anterior height of vertebral body and the vertebral angle were measured before and after operation and during the follow-up period (8 months after operation) through X-ray, the failure of internal fixation and recurrent kyphosis were evaluated during the follow-up period. Vertebral intracorporeal gap was measured by CT images after operation and the central end-plate fracture and reduction were observed by the reconstructed CT images (sagittal and coronary) before and after operation.</p><p><b>RESULTS</b>All patients were followed up from 8 to 15 months with an average of 12 months. Relative anterior height of vertebral body and vertebral angle were well restored after operation, and there was no significant change between after operation and 8 months after operation. Preoperative,postoperative and 8 months after operation, relative anterior height of vertebral body respectively was 40.1%, 98.2%, 97.8%, vertebral angle respectively was 18.30, 2.70, 3.20. No failure of internal fixation and recurrent kyphosis were found during the follow-up period. The vertebral intracorporeal gap was about 3.1% and reduction of central endplate fracture was satisfactory.</p><p><b>CONCLUSION</b>Posterior short-segment pedicle screw fixation combined with vertebroplasty with calcium phosphate cement can provide excellent reduction of post-traumatic segmental kyphosis and restore vertebral body height in the fracture level, prevent the failure of internal fixation which is an ideal method for the treatment of thoracolumbar burst fractures.</p>
