title: Are cervical spine radiograph examinations useful in patients with low clinical suspicion of cervical spine fracture? An experience with 254 cases.
abstract: Trauma patients with low clinical suspicion of cervical spine fracture are often examined with a plain X-ray cervical spine series rather than with cervical spine computed tomography (CT). The authors have been concerned by the absence of fractures in the group of patients examined with plain X-ray. The objective of this investigation was to determine the usefulness of plain X-ray examinations in suspected cases of cervical spine fracture compared to CT. A retrospective review was performed of all trauma patients undergoing imaging for suspected cervical spine fracture in our Emergency Department over a one-year period (January 1, 2007 to December 31, 2007). During the study period, 254 cervical spine plain X-ray and 3,080 cervical spine CT examinations were performed. Of the 254 plain X-ray examinations, 237 were interpreted as negative for fracture, 11 were suboptimal examinations, and six were interpreted as possible fractures (later ruled out by further imaging). Of the 3,080 CT examinations, 2,884 were interpreted as negative for fracture and 196 as positive. The overall positivity rates for acute cervical spine fracture were 0.0% in plain X-ray and 6.4% in CT examinations. These data confirm the authors' concern that plain X-ray imaging for patients with low clinical suspicion for cervical spine trauma in our hospital may have too low a yield to justify its use. However, the 6.4% positivity rate in the group of patients selected for CT examination justifies its use in this group.
