BACKGROUND: The purpose of this study was to describe the clinical and imaging characteristics of patients experiencing blunt spinal trauma without radiological abnormalities but transient or persistent neurological deficits. METHODS: This retrospective study analyzed plain radiographs, computed tomographic scans, and magnetic resonance images of patients with spinal cord injury without radiological abnormality (SCIWORA) who were admitted to a Level I trauma center. Neurologic status, Frankel grade, and short-term patient outcome were assessed. RESULTS: Of 1,604 patients experiencing blunt spinal trauma, 21 (12 men and 9 women) with a mean age of 35.5 years (range, 16.2-70.9 years) presented with a clinicoradiographic mismatch. Magnetic resonance imaging (MRI) was available in 15 patients. In seven patients (46.6%), MRI revealed either neural (n = 2, 13.3%) or extraneural (n = 5, 33.3%) spinal abnormalities. Importantly, in eight patients (53.3%), no spinal abnormalities were visible on MRI. Furthermore, subgroup analysis revealed no prognostic value regarding the presence or absence of detectable spinal injuries. CONCLUSION: Spinal abnormalities were not detected on MRI in a substantial proportion of patients presenting with SCIWORA. The prognostic value of MRI findings in SCIWORA needs to be validated by future studies. (J Trauma Acute Care Surg. 2013;74: 845-848. Copyright (c) 2013 by Lippincott Williams & Wilkins)
