About This Issue

Given the potential for devastating disability and financial consequences of severe spinal cord injury, it is essential for emergency physicians to be able to act quickly to secure the airway and breathing, perform a neurological assessment, determine appropriate imaging, and expedite disposition. This issue reviews:

The key methods for determining and classifying spinal stability.

What the latest guidelines are recommending regarding spinal immobilization – is it still necessary?

Assessing the mechanism of injury to help determine spinal injury: flexion, extension, hyperextension, or axial loading.

The risks for spinal fracture in certain populations, with minimal or no trauma: the elderly, cancer patients, and those with ankylosing spondyloarthropathies.

The most important features of airway management in patients with spine injuries – including delayed airway obstruction – and the latest evidence on orotracheal intubation techniques.

NEXUS and the Canadian c-spine rule: using clinical decision rules to determine who is safe to discharge without imaging.

Using the Denver criteria to determine when further imaging for blunt cerebrovascular injury is needed.

Whether blood pressure augmentation and steroid therapies will help or hurt.

Abstract

The majority of the nearly 18,000 new cases of spinal cord injury in the United States each year involve the cervical spine. Although the morbidity, mortality, and healthcare costs associated with these injuries is very high, quality evidence to guide emergency management is limited. Recent changes to guidelines have called into question decades of practice, including prehospital spinal immobilization protocols, timing of surgery, and pharmacotherapy. A systematic approach to the diagnosis and management of the spine-injured patient is outlined in this review, with a focus on recent updates and management of emergent complications.

Case Presentations

CASE 1
EMS calls to alert you that they have 24-year-old man with head trauma, and they are 15 minutes out…
  • EMS says the man was found down on the street.
  • He has head trauma and a GCS score of 7, but his vital signs are normal.
  • You anticipate that this patient will need intubation. The EMS crew asks whether they should intubate in the field and whether he requires spinal immobilization...
CASE 2
A 64-year-old man walks into the ED complaining of left-sided neck pain after he was in a head-on motor vehicle crash several hours ago…
  • A resident is examining the patient, who said he was a restrained driver in the MVC, and the airbags did not deploy. He was ambulatory at the scene, and refused to go to the ED at that time, but now complains of left-sided neck pain.
  • On exam, he has left-sided paraspinal tenderness to palpation over the cervical and lumbar spinal area without step-offs or deformity. No neurological deficits are noted on exam.
  • The resident asks you whether the patient should be placed in a hard collar and whether imaging is appropriate…
CASE 3
A trauma is called overhead: a young woman was thrown from a horse onto her head and back…
  • You run to the trauma bay where the young woman has been brought in by EMS. The trauma resident is evaluating her ABCs.
  • You see that the patient is awake, has a GCS score of 15, and is answering questions appropriately, but she appears uncomfortable.
  • Her blood pressure on the monitor is 80/48 mm Hg. As the resident finishes the primary survey, you note that the patient is unable to lift her lower extremities on command. Her grip strength is weak, and she has gross loss of sensation in the bilateral upper extremities.
  • You wonder whether this is a head or a spine injury, and how best to treat her hypotension. Should she receive corticosteroids?
