ASSESSMENT OF OUTCOMES OF MINIMALLY INVASIVE SURGERY FOR UNSTABLE THORACOLUMBAR SPINE FRACTURES USING PERCUTANEOUS PEDICLE SCREW FIXATION AT MILITARY HOSPITAL 103
Main Article Content
Abstract
Objectives: To evaluate the surgical outcomes of percutaneous pedicle screw fixation for treating unstable thoracolumbar spine fractures. Methods: A retrospective and prospective, descriptive study was conducted on 35 patients with unstable thoracolumbar spine fractures who underwent percutaneous pedicle screw fixation at Military Hospital 103 from July 2021 to May 2024. Results: The mean patient age was 45.06 ± 11.39 years, with 77.1% males. Occupational accidents were the main cause (62.9%), and L1 was the most frequently affected vertebra (48.6%). The mean operative time was 86.26 ± 13.78 minutes, with an estimated blood loss of 112.6 mL and a hemoglobin drop of 3.8 g/L, and no patient required blood transfusion. Pain scores (VAS) decreased from 7.49 preoperatively to 1.83 postoperatively. The kyphotic angle decreased from 15.8º to 5.68º (p < 0.05) and remained stable. No complications, including infection, neurological injury, or implant failure, were observed during long-term follow-up. Conclusion: Percutaneous pedicle screw fixation is a safe, minimally invasive, and effective technique that reduces pain and blood loss while restoring spinal alignment in the treatment of unstable thoracolumbar spine fractures.
