BackgroundTraumatic spinal injuries (TSI) pose a significant life-long burden, impacting both military and civilian populations. Assessing long-term outcomes is crucial for comprehending the enduring consequences of the initial insult and informing effective prevention and management strategies. Most existing studies have narrowly focused on subsets of traumatic cord injuries, leaving a gap in understanding the broader impact of severe spinal trauma. This study aims to examine severe TSIs in military personnel, who may face unique risk factors and injury patterns, and its association with long-term disability.MethodsA retrospective cohort study was conducted on all military personnel who suffered traumatic injuries (Injury Severity Score ≥ 9) from 1997 to 2020. Severe spinal injuries were defined using the spinal Abbreviated Injury Scale ≥ 3 (n = 95), and compared to all other injuries as a reference group (n = 1,394). Data were extracted and cross-referenced from three distinct nationwide registries-pre-hospital, admission, and rehabilitation. Logistic regression analysis was used to evaluate the impact of spinal injuries on long-term disabilities (defined as the highest possible disability tier). The study received approval from the institutional review board of the Israel Defense Forces Medical Corps.ResultsMotor vehicle accidents and falls were the primary causes of spinal injuries (50.5% and 15.8%, respectively). The median age at injury was 20 years (interquartile range 19-22). Personnel with spinal trauma had a significantly higher prevalence of Injury Severity Score  ≥ 25 (46.3% vs. 19.9%, P < .001), longer median hospital stays (11 vs. 8 days, P = .036), and increased intensive care unit admissions (55% vs. 40%, P = .05). The median follow-up duration was 10.9 years (interquartile range 6.7-14.3). Spinal injuries were associated with a more than 10-fold increase in the adjusted odds ratio for severe permanent disability (11.92, 95% CI, 5.95-23.72).ConclusionUpon long-term follow-up, military personnel with severe TSI exhibit a significantly higher prevalence of debilitating disability compared to those with significant non-spinal traumatic injuries. These findings highlight the critical need for targeted prevention strategies and improved management of spinal injuries to reduce long-term disability. Strengths of this study include its extensive follow-up period and the use of multiple nationwide registries. However, the study may be limited by potential discrepancies in identity matching across databases and the reliance on disability claims, which may underrepresent the true prevalence of long-term disability. Future research should explore the efficacy of early interventions and rehabilitation strategies in mitigating long-term disability following spinal injuries. This study underscores the importance of developing evidence-based policies to enhance care for individuals with TSIs.© The Association of Military Surgeons of the United States 2024.
