Background

Clinical Features

  • Often associated w/ brain injury

Diagnosis

  • Evaluate with the Powers ratio
    • Ratio of BC:OA > 1 suggests anterior subluxation
    • BC = distance between basion and midpoint of C2 post laminar line
    • OA = Distance between opisthion and ant arch of C2

Differential Diagnosis

Vertebral fractures and dislocations types

Vertebral anatomy.
Numbering order of vertebrae.

Workup

Atlanto-occipital Dissociation

Management

Prehospital Immobilization

See the NAEMSP National Guidelines for Spinal Immobilization

Hospital

  • C-collar
  • Consult ortho or spine as needed

Disposition

  • Admit
