Clinical results of surgical treatment for thoraco-lumbar burst fractures were studied. Fourteen patients (eight males and six females, average age 36.8 years) who were operated for posterior decompression and fusion were evaluated. The fusion of the instrumentation (pedicle screw system) applies to two areas above and two below the injured vertebral body. There was screw breakage and the average correction loss for Cobb's angle between the first examination after operation and the final follow-up examination was 1.1 degrees in this series. As a result, clinical results of the surgical treatment were thought to be evaluated as good. But our surgical method may be too invasive to be safe, and the fusion area may be too extensive to prevent complications. In conclusion, in cases of severe communicated vertebral body, the hybrid construction method and our method are thought to be recommended. In cases of moderate grade transpedicular fixation with transpedicular bone graft in addition to the above is thought to be recommended. In mild cases, the so-called short fusion is thought to be recommended.
