Prospectively collected patient reported functional outcomes and post-operative complications were also studied.Stepwise regression analysis adjusted by age, gender and functional scores was performed to account for the small numbers andunequal sizes of the groups.Results: Back pain score was significantly lower in the FL group (P < 0.025). Core Outcome Measures Index scores and leg painscores, though low in the FL group, were not statistically significant. The regression analysis showed that the inclusion of thefracture-level screw was independently associated with a greater change in sagittal index and vertebral height restoration post-operatively. Sagittal index was maintained through to final follow up as well. The bi-segmental Cobb{\textquoteright}s angle correction was notassociated with fracture-level screw construct. There was no significant difference between the groups for revision surgery, deepinfection, implant failure or length of hospital stay.Conclusion: The inclusion of the fracture-level pedicle screws in the fixation construct significantly improves the immediate andfinal measured radiological parameters, with improved functional scores in single level unstable vertebral fractures of thethoracolumbar junction.",
