Summary

Helical computed tomography (CT) reliably clears the cervical spine in unconscious trauma patients. Dynamic screening offers no significant advantage over CT, especially when Power

Area of Science:

  • Emergency Medicine
  • Radiology
  • Orthopedic Surgery

Background:

  • Cervical spine clearance in unconscious trauma patients remains debated.
  • Helical computed tomography (CT) is hypothesized to be sensitive enough to replace dynamic screening.
  • Current protocols involve plain radiographs, CT, and dynamic screening.

Purpose of the Study:

  • To evaluate the efficacy of helical CT in cervical spine clearance.
  • To determine if dynamic screening is redundant in unconscious trauma patients.
  • To assess the sensitivity and specificity of CT versus dynamic screening.

Main Methods:

  • Retrospective review of 839 trauma patients over 10 years.
  • Analysis of cervical spine clearance protocols including plain radiographs, CT, and dynamic screening.

  • Recording of unstable cervical spine injuries and missed diagnoses by CT.

    • Main Results:

    • 87 patients had unstable cervical spine injuries; CT detected 85 (97.7% sensitivity).
    • Two cases were missed by CT, one detected by dynamic screening.
    • Dynamic screening missed one atlanto-occipital dislocation; Power's ratio on CT would have detected it.

    Conclusions:

    • Dynamic screening is safe but not superior to helical CT.
    • Power's ratio calculation on CT is crucial for detecting upper cervical injuries.
    • Helical CT alone is sufficient for reliable cervical spine clearance in unconscious patients.
