Abstract

Background: Management of unstable thoracolumbar fracture remains controversial between short segment and long segment pedicle screw fixation. Surgical stabilization is indicated to adequately decompress the spinal canal, maximizing neurological recovery and creating spinal stability. 
Materials and Methods: A comparative study in unstable thoracolumbar fractures fixed with short and long segment transpedicular screw fixation was done and followed up for 6 months. For functional assessment Modified MACNAB criteria, Oswestry disability index and Visual analogue scale scoring system used. Neurological status, radiological kyphotic angle correction were analyzed.
Results: A total of 30 cases were included in the study of which 23 were male and 7 females. The mean age was 36.77 years. Younger individuals were more susceptible to road traffic accident. L1 was the most common vertebral level involved. Cases with a higher ASIA grade had a better improvement post operatively compared to one with a lesser ASIA grade preoperatively (P Value 0.003). Cases with lesser number of transfers had a better outcome at final followup. (P value 0.018). At all months of followup both short and long segment fixation groups have statistically significant kyphotic deformity correction, but long segment have better correction with 19.86 degrees pre-operative to 8.8 degrees at the end of 6 month of followup.
Conclusion: Short segment transpedicular fixation gives better functional outcome than long segment transpedicular fixation, but long segment transpedicular stabilization gives better radiological results in the form of kyphotic deformity correction.
