Our experience and the literature demonstrated that a favorable outcome with resolution of neurologic symptoms can often be achieved after excision or ablation of the epidural varices.
Introduction: The optimal management of thoracolumbar spine fractures remains a matter of controversy. The current literature implies that the use of short-segment pedicle screw fixation may be inappropriate because of its high reported failure rate. The purpose of this study is to report the short-term results of thoracolumbar burst and compression fractures treated with short-segment pedicle instrumentation. Materials and Methods: From 2002 to 2007, 19 patients with thoracolumbar acute traumatic fractures were instrumented with posterior short-segment pedicle screws. The patients’ case notes, operation records, preoperative and postoperative radiographs (sagittal index, anterior body compression and regional kyphosis), computed tomography scans, neurological findings (Frankel functional classification), and follow-up records up to 18 months were reviewed. Results: A statistically significant difference was found between the patients’ preoperative, postoperative and follow-up sagittal index, anterior body compression and regional kyphosis measurement. One case resulted in screw pedicle screw pullout and subsequently, kyphotic deformity. The patient underwent revision surgery to long-segment posterior instrumentation and fusion. None of the patients showed an increase in neurological defi cit. Conclusion: In conclusion, the short-term follow-up results suggest a favourable outcome for short-segment instrumentation. Load shearing classification is essential for the selection of patient for short-segment instrumentation. However, the long-term follow-up evaluation will be needed to verify our findings.
