Abstract

Background: Thoracolumbar spine trauma represents a serious clinical condition that may result in significant morbidity, including permanent motor and sensory deficits. Consequently, the application of the AOSpine classification system to computed tomography imaging has gained increasing attention. Objective: To describe computed tomography imaging characteristics and classify thoracolumbar spine trauma according to the AOSpine classification system. Materials and Methods: A descriptive cross-sectional study was conducted on 52 patients who were clinically diagnosed with thoracolumbar spine trauma and underwent computed tomography examination at Can Tho Central General Hospital between November 2022 and July 2024. Results: The mean age of patients was 59.4 ± 14.0 years, with a female-to-male ratio of 2.25:1. Domestic accidents were the most common cause of injury, accounting for 67.3% of cases. Neurological status assessment revealed that 42.3% of patients had no neurological deficit (N0), while complete spinal cord injury (N4) was observed in 5.8% of cases. According to the AOSpine classification, type A1 vertebral body fractures were the most frequently encountered morphology (36%). Among the 52 patients evaluated using the Thoracolumbar AOSpine Injury Score (TL AOSIS), 22 cases scored ≥ 6, all of whom received surgical treatment. Conclusion: This study provides a comprehensive evaluation of thoracolumbar spine fracture morphology on computed tomography using the AOSpine system. The findings contribute to enhancing diagnostic accuracy and support appropriate treatment decision-making for patients with thoracolumbar spine trauma.
