SPINE TRAUMA

 

 

Initial Assessment of Spinal Trauma
Karim Brohi, trauma.org 7:4, April 2002

Introduction

The diagnosis of an unstable spinal injury and its subsequent management can be difficult, and a missed spine injury can have devastating long-term consequences. Spinal column injury must therefore be presumed until it is excluded.

Initial Assessment of Spinal Trauma

     Introduction
     Spinal Stabilization
     Clinical Clearance
     Conscious Patients
     Unconscious Patients
     Thoracic & Lumbar Spine
     Paediatric Spinal Injury

Some studies of spinal trauma have recorded a missed injury rate as high as 33%. Delayed or missed diagnosis is usually attributed to failure to suspect an injury to the cervical spine, or to inadequate cervical spine radiology and incorrect interpretation of radiographs. An appropriate procedure for the evaluation of the potentially unstable spine must be robust and easy to implement, with a high sensitivity, given the potential importance of such injuries. It must also address the main issues raised by the modalities available for diagnosis.

For spinal trauma, the main concerns are which patients can be cleared by clinical exam alone, how many plain X-rays are necessary and when should additional imaging using Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) be used. An assessment for ligamentous injury in the absence of a fracture is also important, especially in unconscious patients who are unable to complain of neck pain or tenderness.

While it is tempting to focus on the cervical spine, it is important to assess and clear the entire spinal column. The thoracolumbar spine, while more protected, is at risk in major trauma and must be assessed both clinically and radiologically. Additionally, 5% of spinal injuries have a second, possibly non-adjacent, fracture elsewhere in the spine.

These pages discuss the initial assessment and management of the potentially spine injured patient. The actual protocol implemented at any given institution will depend on the expertise and facilities available. Where the required expertise or imaging are not available in a given institution, the protocol should encompass criteria for expeditious transfer of patients to specialist care.
