We present a case of upper airway obstruction in a patient with an unstable cervical spine fracture in a halo orthosis. We also describe the mechanism by which the obstruction occurred and identify features that predispose patients in a halo orthosis to upper airway obstruction. ⋯ In this case, external cervical spine fixation in flexion resulted in a change to the O-C2 angle, which reduced the oropharyngeal area and predisposed to upper airway obstruction. This highlights the need for anesthesiologists to evaluate the degree of cervical spine flexion in patients with halo devices and to have the surgical team present during airway management in the event of acute airway obstruction.
