Insights

Most recent cervical spinal cord injuries (cSCI) occur in older adults without fracture or dislocation, often from low-impact events. Current management guidelines may not apply to this evolving patient demographic.

Area of Science:

  • Neurosurgery
  • Trauma Surgery
  • Spinal Cord Injury Research

Background:

  • Existing acute spinal cord injury guidelines primarily address young individuals with spinal fracture dislocations from high-impact trauma.
  • Recent clinical observations suggest a shift in the demographic and injury patterns of cervical spinal cord injuries (cSCI).

Purpose of the Study:

  • To characterize the contemporary patient population with cSCI at a level 1 trauma center.
  • To compare current cSCI demographics and injury types against traditional profiles used in guideline development.
  • To test the hypothesis that most cSCI patients now fall outside the scope of established guideline principles.

Main Methods:

  • A cross-sectional cohort study design was employed.
  • Demographics, injury types, and diagnoses of cSCI patients admitted over 12 months were reviewed.
  • Data were cross-referenced from multiple archival systems at a level 1 trauma institution.

Main Results:

  • Eighty-two percent of 51 identified cSCI patients lacked spinal fracture or dislocation.
  • These patients were older (mean age 62), sustained low-impact injuries (93%), and had lower American Spinal Injury Association (ASIA) grades (98%).
  • In contrast, patients with fracture/dislocation were younger (mean age 48), had high-impact injuries (77%), and higher ASIA grades (66%).
  • Ninety-eight percent of cSCI patients without fracture/dislocation presented with hand/arm sensory and motor deficits, versus 11% with fracture dislocation (P < 0.0001).

Conclusions:

  • Patients with cSCI without fracture or dislocation now constitute the majority at this trauma center.
  • This demographic aligns with central cord syndrome, suggesting distinct pathophysiology and natural history.
  • Applying management principles from older guidelines to this new patient population is not straightforward.

The Spinal Cord01:54

The Spinal Cord

The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Spinal Cord

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.

Spinal Cord Injury ll: Pathophysiology01:14

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

Secondary Spinal Cord Injury llI: Pathophysiology01:25

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
