TI  - Surgical Outcome in Thoracolumbar Fractures Managed by Short-segment Pedicle 
      Instrumentation.
PG  - 24-32
AB  - INTRODUCTION: This study aims to evaluate the efficiency of short-segment 
      instrumentation in treating thoracolumbar fractures in our institute. MATERIALS 
      AND METHODS: Twenty-two patients underwent posterior short-segment 
      instrumentation for thoracolumbar fractures in our institute from 2007 to 2010 
      were included in this retrospective study. Radiological evaluations were carried 
      out by measuring regional kyphosis angle (RA), anterior vertebral body 
      compression percentage (AVC), and sagittal index (SI) during preoperative, 
      postoperative and final follow-up, with the aim to investigate the rate of 
      correction loss and implantation failure in relation to the Arbeitsgemeinschaft 
      fur Osteosythese(AO) classification of fracture system and the Load Sharing score 
      system. CT scans were also used to determine the preoperative to postoperative 
      canal compromise ratio. During the final follow-up, clinical outcomes were 
      analysed based on scores from the Denis' Pain's and Work scales and neurological 
      function was scored according to the Frankel classification. RESULTS: At the 
      final follow-up (average duration of 15 months), 21 patients (95%) who partially 
      or fully recovered from thoracolumbar fractures were able to resume daily 
      activities with no complaints of pain, or only slight pain. No deterioration in 
      neurological function were recorded. Upon evaluation at each point of time, 
      (preoperative, postoperative and final follow-up), the average RA improved from 
      21 masculine to 3.5 masculine to 5.6 masculine, average AVC improved from 40.8% to 90.2% to 88.2%, and 
      average SI changed from 19.1 masculine to 3.1 masculine to 4.1 masculine, respectively. Average canal 
      compromise ratio decreased from 45% to 6.7% after surgery. No correlation was 
      found between loss of correction and AO classification of fracture system, and 
      loss of correction and Load Sharing system scores. Also, no correlation was found 
      between clinical outcomes and the correction loss limited to 10 masculine. CONCLUSION: 
      Posterior short-segment fixation in thoracolumbar fractures showed a satisfactory 
      outcome in 95% of the patients based on a 15-month follow-up in our institute, 
      even among patients with comminuted fractures injuries.
