Abstract

The aim of the study is to study the radiological outcomes of pedicle screw fixation in unstable dorsolumbar fractures by measuring the correction in various parameters namely Regional angle. Obtain images of the spine to confirm the degree of spinal reduction and determine the limits of the incision. Prepare and drape the thoracolumbar spine to be instrumented and the iliac crest. Make an incision from one spinous process above the area to be instrumented to one spinous process below the area to be instrumented. Result: In this study sex ratio among the patients was 1.5:1(M:F) 36 patients out of 60 were male and rest females. In this series most commonly fractured vertebra was found to be L1 followed by D12. There was a statistically significant improvement in mean anterior wedge angles with a p value off less than 0.001. Most of the patients at 6 months follow up only have a occasional minimal pain with no need of medications. Conclusion: In long term the radiological parameters namely anterior wedge angle, regional angle and vertebral body height ratio, which are the measure of deformity are well restored showing the efficacy of pedicle screw fixation in deformity correction and its maintenance. There is a very high statistically significant restoration of these parameters
