A comparison of flexion and extension radiographs with computed tomography of the cervical spine in blunt trauma.
The purpose of this study was to compare flexion and extension (F/E) cervical radiographs with CT of the cervical spine in patients sustaining blunt trauma for the evaluation of ligamentous injury. A retrospective chart review of 2 years duration at an American College of Surgeons-verified Level I trauma center was performed. All patients sustaining blunt trauma who were evaluated with both a CT as well as F/E radiographs were identified. Exclusion criteria included penetrating injuries, neurologic symptoms, and age younger than 18 years. Follow-up MRI of each positive F/E radiograph after a negative CT scan was performed. Flexion and extension cervical radiographs were obtained in 379 patients after CT. Eight positive F/E radiographs were obtained after a negative CT scan. Follow-up MRI was negative for ligamentous injury in all cases. No cases of a clinically relevant positive F/E radiograph after a negative CT scan were identified. Follow-up F/E radiographs are not efficacious when a negative CT has been performed in blunt trauma without neurologic findings.
