A comprehensive analysis of traumatic atlanto-occipital and atlanto-axial dislocations: A case series from a level one trauma center.

Introduction: Traumatic atlanto-occipital dislocations (AOD) and atlanto-axial dislocations (AAD) are catastrophic injuries of the craniovertebral junction associated with high mortality and long-term morbidity. These injuries' outcomes are often poor due to severe neurological damage and challenges in management. This study aims to provide a comprehensive analysis of AOD and AAD cases at a level one trauma center in the Southwestern United States, in regard to injury characteristics, management strategies, and patient outcomes. Methods: A retrospective review was conducted on traumatic AOD and AAD patients admitted to a single trauma center between January 1, 2018, and November 14, 2023. Data included demographics, injury mechanism, clinical course, and post-injury outcomes. Patients were categorized into dislocation and subluxation groups. Statistical analyses were performed using Chi-square and independent Results: The cohort included 8 dislocations and 13 subluxation patients, with a mean age of 39.25 years. Motor vehicle collisions were the predominant injury mechanism (42.86 %). Patients with dislocations had significantly higher mortality rates compared to subluxations ( Discussion: This study emphasizes the severity of AOD and AAD traumatic injuries. Despite advances in management, these injuries remain highly lethal and result in significant disability for survivors. Our findings emphasize the need for improved diagnostic protocols and early intervention strategies. Future research should focus on multicenter studies to validate current literature and explore novel therapeutic approaches to improve patient outcomes.
