Objective: The purpose of this study was to compare clinical and radiologic outcomes of patients who underwent short-segment posterior instrumentation with screw augmentation at the fracture level and long-segment instrumentation for thoracolumbar junction fractures.
Methods: Sixty-three patients were retrospectively evaluated by being divided into the following 4 groups: Groups A, B, C, and D included patients who had undergone 4-level instrumentation without insertion of screws at the fracture level, 3-level instrumentation by insertion of screws at the fracture level, 4-level instrumentation by insertion of screws at the fracture level, and 5-level instrumentation by insertion of screws at the fracture level, respectively.
Results: No significant difference was observed in preoperative local kyphosis angle (LKA) (P > 0.
