All patients underwent lumbosacral computed tomography, and each injured vertebra was classified according to the AOSpine classification system. The frequency and percentage of subtypes of lumbosacral spine trauma were determined.Results: The mean age of the patients was 50.6 ± 16.1 years, and the male-to-female ratio was 1.5:1. Falls and traffic accidents were found to be the main causes of injuries. Among the patients, 78.7% did not exhibit any neurological symptoms, while 1.3% experienced complete hemiplegia and 20% had incomplete hemiplegia. The most common fracture subtype was A3, accounting for 34.6% of cases.Conclusion: This study provides valuable insights into the demographics, associated injuries, and classification of traumatic lumbosacral spine injuries based on the new AOSpine classification system. The study found that falls and motor vehicle accidents were the main causes of these injuries, with a higher proportion of male patients. The majority of injuries were classified as type A fractures, while type C fractures were the least common. Sacral fractures were relatively infrequent and often associated with pelvic ring fractures. These findings contribute to our understanding of lumbosacral spine trauma and can aid in the development of more effective treatment protocols.Keywords: lumbosacral spine injury, AOSpine classification, computed tomography
