Abstract:
BACKGROUND:There are many methods to treat thoracolumbar fractures However,it remains unclear whether a simple operation to treat a thoracolumbar burst fracture can decrease the trauma and obtain better effect to avoid the enlargement of operation.OBJECTIVE:To investigate the clinical outcome of posterior short-segmental transpedicular screw system internal fixation in treatment of single-level thoracolumbar burst fracture without nerologic deficit.METHODS:A total of 186 patients with single.level thoracolumbar burst fracture but without nerologic deficit treated in the First Affiliated Hospital of Soochow University between September 2003 and January 2008,including 152 males and 34 females,aged18 10 65 years.were treated by posterior pedicle screw The intraspinal bone fragments were treated with indirect decompression.All patients were checked with radiography and CT scan before/after operation as well as before implant removal.The correction of anterior vertebral body height and the ratio of bone fragment to cross section area of spinal canal were measured.RESULT AND CONCLUSION:Compared with normal.the anterior vertebral body height was 42%before operation,98%after operation,and 98%before implant removal The ratio of bone fragment to cross section area of spinal canal was 34%before operation,13%after operation.and 8%before implant removal.Internal posterior short-segmental transpedicular screw fixation treating single-level thoracolumbar burst fracture without nerologic deficit can obtain stability of spinal column,and it is beneficial to recovery of body height,physiologic postu ral contour and canal volumn .
