ObjectiveTo investigate the clinical characteristics and methods of diagnosis and treatment multiple level thoracolumbar spinal fractures.MethodsFrom March 2002 to March 2006, 17 patients with 35 thoracolumbar spinal fractures were treated, 13 males and 4 females, aged 21-52 years old (36.4 on average), among whom there were 10 cases of traffic accident injury and 7 of high falling injury. One fracture was located at T2, 1 at T3, 1 at T10, 4 at T11, 6 at T12, 5 at L1, at L2, 7 at L3, 5 at L4, and 2 at L15, with a total of 35 segments including 26 segments with unstable fractures and 9 segments with stable compression fractures. According to the Frankel grade, there was 1 case of grade A, 1 of grade B, 2 of grade C, 5 of grade and 8 of grade E. The preoperative height of the anterior border of the vertebral body was (20.8 +/- 3.8) mm and the preoperative kyphosis angle was (16.2 +/- 3.4) degrees. All the unstable fractures were performed operation. Sixteen injured vertebras were treated with long-segment pedicle screw internal fixation; 8 were treated with short-segment pedicle screw internal fixation, and 2 were treated with anterior fusion and fixation. Five injured vertebras with stable compression fractures were not treated and 4 were treated with pedicle screw implantation.ResultsThe operation time was 1.8-4.2 hours and the amount of blood loss was 300-900 mL. The incisions obtained healing by first intention after the operation. All 17 patients were followed up for 13-41 months (18 months on average), and radiological evaluation showed no failure of the internal fixation. After the operation, Frankel scale assessment showed that 1 patient of grade A improved to grade B, 1 of grade B improved to grade C, 1 of grade improved to grade D, 1 of grade C improved to grade E, 5 of grade D improved to grade E, and 8 of grade E had no improvement. At the final postoperative follow-up, the height of the anterior border of the vertebral body was (31.9 -/+ 3.2) mm and kyphosis angle was (6.8 +/- 3.7) degrees, which were significantly different from those of preoperation (P < 0.01).ConclusionThe treatment of multiple level thoracolumbar spinal fractures should be individualized according to the patients' actual conditions in order to obtain decompression and stability of spines.
