More than 5-Year Follow-up Results of Two-Level and Three-Level Posterior Fixations of Thoracolumbar Burst Fractures with Load-Sharing Scores of Seven and Eight Points
Five-Year Results Comparing Two-Level and Three-Level Back Fixations for Severe Mid-Back Burst Fractures

Abstract
No cases of non-union or implant loosening were observed in 45 patients with thoracolumbar burst fractures.
- Two-level posterior fixation was assessed in 28 patients, while three-level fixation was evaluated in 17 patients.
- Two screw breakages occurred in the two-level fixation group, but bony union was achieved at the final follow-up.
- No significant differences were found in anterior vertebral body height loss, correction loss, or changes in adjacent discs between the two groups.
- Clinical evaluations indicated no significant differences in neurological deficits among patients during the follow-up period.
- Two-level posterior fixation may be successfully utilized in selected cases of thoracolumbar burst fractures with load-sharing scores of 7 and 8.
