    Objectives: To investigate the prevalence and risk factors of the misplacement of the pedicle screw in patients with thoracolumbar spine fracture. Methods: Patients who underwent posterior stabilization procedure due to thoracolumbar spine fracture were included. Association between potential risk factors and the misplacement of the pedicle screw were evaluated by logistic regression analysis. Results: A total of 88 consecutive patients with thoracolumbar spine fracture who underwent posterior stabilization surgery using pedicle screws and rods (mean age 43 ± 14, male 52.3 %). On post-operation CT evaluation, 98 (14.8 %) pedicle screws were misplaced (34 thoracic screws and 64 lumbar screws) and the prevalence of the misplaced pedicle screw was not significantly different between thoracic and lumbar screws (13.2 % vs. 15.8 %, p = 0.347). Among risk factors including location of spine fracture, multiple spine fracture and location of screws, the AO classification of spine fracture was significantly associated with the misplacement of the pedicle screw (OR = 1.27, 95 % CI 1.06 - 1.53, p = 0.011). Conclusion: High grade spine fracture, as assessed by the AO classification, was significantly associated with pedicle screw misplacement in patients with thoracolumbar spine fracture.

    Posterior fixation is usually performed to restore spinal stability and decompress the spinal canal for unstable thoracolumbar burst fractures.The purpose of this study was to compare trunk and lower-extremity kinematics during gait between healthy adults and patients who had undergone posterior fixation surgery after thoracolumbar fractures.Optical motion capture was used to record joint kinematics during walking.The trunk, hip, knee, and ankle joint angles and excursions in sagittal, frontal, and transverse planes were calculated, averaged, and compared between patients and control groups.The patient group had significantly increased total hip excursion in the frontal plane and reduced ankle dorsiflexion in the sagittal plane, with mean differences of 4.2 • and 6.4 • , respectively.However, there were no differences in knee joint kinematics.The patient group exhibited a more upright trunk position during walking than the control group, with both peak trunk flexion and extension significantly different, possibly indicating stiffer trunk movement.This study provides the fundamentals of the joint kinematics of the trunk and lower extremities after posterior surgical treatment for thoracolumbar fractures, which may help in evaluating surgical outcomes.
