Core Tip

Core Tip: A single center ambispective non-randomized evaluation of 204 consecutive patients with unstable thoracolumbar injuries treated pedicle screw fixation. Patients with pedicle screw loosening were identified using computed tomography, and those cases with clinically significant complications were registered. Multivariate logistic regression and general discriminant analysis suggest that the rate of pedicle screw loosening depends on bone radiodensity, length of fixation, type and extensiveness of decompression. Auxiliary posterior fusion, intermediate screw and anterior reconstruction can provide a clinically significant decrease in complication rate.
