Percutaneous Fixation of Mechanically Unstable Thoracolumbar Spine Fractures: Initial Experience in Minia University Hospital.

Aim of the study: To assess the initial clinical, functional and radiological outcomes of percutaneous fixation of mechanically unstable thoracolumbar spine fractures. Methods: This prospective study was performed on 30 patients with mechanically unstable thoracolumbar spine fractures according to Thoracolumbar AO Spine injury score (TLAOSIS). The age of patients ranged between 19 -50 years. All patients were treated with percutaneous fixation technique during the period from June 2024 to March 2025. Results: The mean operative time was 75.7 ± 19.4 minutes. Significant improvement was observed in all radiological metrics at the last follow-up, comprising the average measurements of bi-segmental Cobb's angle (BCA), vertebral body angle (VBA), and anterior vertebral body height (AVBH) 7.7˚ ± 3.4˚, 6.2˚ ± 2.9˚, and 18.4 ± 1.7 mm, respectively. The final average scores for VAS, ODI, and Prolo economic and functional rating scales were 0.6 ± 0.6, 1.4 ± 1.3, and 9.4 ± 0.5, respectively. There was no notable blood loss during the operation, and no serious complications were reported after surgery. Conclusion: Percutaneous pedicle screw fixation is an efficient technique for stabilizing thoracolumbar fractures, demonstrating satisfactory correction of radiological parameters, reduced morbidity associated with the approach, and a quicker return to functionality compared to traditional open surgery.
