The authors’ positioning technique for anterior odontoid screw fixation involves using an intravenous pressure bag, a widely available device in hospitals and operating rooms, to support the patient’s neck while supine. (A) Intravenous pressure bags are inflatable devices used to bolus intravenous fluids. (B) The contour of the intravenous pressure bag not only supports, but also matches the contour of the neck. Absolute neck stability is crucial during anterior odontoid screw fixation to minimize iatrogenic injury and navigational inaccuracy. This image is published with the participant’s consent.
