The evaluation of the cervical spine in the emergency department is a common and often challenging task. We report the case of a 70-year-old female who presented intoxicated with evidence of a recent fall. A 64-slice computed tomographic (CT) scan with sagittal and coronal reconstructions revealed no acute injury. The patient was reexamined when alert and had persistent neck pain. Flexionextension static views revealed severe subluxation of C5 on C6 with jumped facets, and subsequent magnetic resonance imaging confirmed significant ligamentous injury. The evidence available suggests that although CT with reconstruction is highly sensitive for clinically significant cervical injury, the possibility of severe injury remains.
RÉ SUMÉL'é valuation de la colonne cervicale au service des urgences est une tâ che courante et souvent difficile. Nous signalons le cas d'une femme de 70 ans qui s'est pré senté e aux urgences en é tat d'é brié té et portant des signes d'une chute ré cente. Un tomodensitogramme à 64 coupes par reconstruction frontale et sagittale n'a ré vé lé aucune lé sion aiguë . La patiente, une fois consciente, a é té ré examiné e et souffrait d'une douleur persistante au cou. Des cliché s statiques en flexion-extension ont ré vé lé une subluxation grave de C5 sur C6 et des facettes disloqué es, et un examen subsé quent d'imagerie par ré sonance magné tique (IRM) a confirmé une lé sion ligamentaire importante. Les donné es disponibles permettent de pré sumer que bien que la sensibilité du tomodensitogramme par reconstruction soit é levé e en cas de lé sion cervicale importante sur le plan clinique, la possibilité de lé sion grave demeure.
