Traumatic Spinal Cord Injury: A Contemporary Review of Classification, Evaluation, and Acute Management

Traumatic spinal cord injury (SCI) is a catastrophic condition associated with profound neurologic disability, psychosocial disruption, high long-term healthcare utilization, and reduced life expectancy. Globally, SCI remains a major cause of morbidity, most commonly resulting from traumatic mechanisms such as motor vehicle collisions and falls, with a bimodal age distribution affecting both younger adults and older individuals. This narrative review provides a comprehensive, clinically oriented overview of SCIs with emphasis on classification, initial evaluation, imaging, and contemporary management strategies. The review highlights the dual-phase pathophysiology of SCIs-primary mechanical insult followed by secondary injury cascades-underscoring the rationale for rapid stabilization and timely, injury-specific interventions. Initial care is framed around immobilization and trauma resuscitation principles, with cervical spine clearance guided by validated decision tools and early, appropriate imaging acquisition. We discuss adjunctive imaging considerations and address the ongoing debate regarding MRI use in obtunded patients with negative initial studies. Acute inpatient management priorities include prevention of secondary complications, hemodynamic optimization, respiratory support, and vigilant surveillance for autonomic dysfunction. Pharmacologic neuroprotection with high-dose methylprednisolone remains controversial; current guideline recommendations are reviewed. Finally, we outline operative decision-making and evidence supporting early decompression in selected patients, as well as common surgical approaches and their indications. This review consolidates foundational concepts and current standards to support practical, evidence-informed SCI evaluation and management.
