    Abstract

    Study Design

    Retrospective study.

    Objectives

    The purpose of this study is to compare the outcomes of short segment fusion and long segment fusion in posterior facet fracture-dislocation in the lumbar spine.

    Summary of Literature Review

    There are many controversies exist about the treatment of fracture-dislocation in lumbar spine.

    Material and Methods

    Sixteen patients with lumbar fracture-dislocation were studied retrospectively. The patients divided two groups; group one treated with one level above and below the fracture segment fixation, group two treated with two level above and below the fracture segment fixation. Two groups were compared with neurologic recovery, bladder function recovery and radiologic changes of deformities.

    Results

    The neurologic deficit in two groups was improved more than one Frankel grade at last follow up. Patients who showed intact dura were neurologically improved significantly than the patients whose dura was ruptured. Radiologic changes were not a sinificant difference in two groups.

    Conclusion

    In lumbar fracture-dislocation treatment, one level above and below the fracture segment fixed with pedicle screw fixation system was an effective treatment method which preserved the mobile segment lumbar spine.
