SCIWORA

Abstract

Spinal cord injury without radiographic abnormality (SCIWORA) is a concept introduced to defi ne "clinical symptoms of traumatic myelopathy with no radiographic or computed tomographic features of spinal fracture or instability." Specifi c biomechanics of the vertebral column in children allow the musculoskeletal system to move beyond the normal physiological range of motion without the risk of fracture, a feature not shared by the spinal cord. Early diagnosis of spinal cord injury is important to optimize clinical outcome. MRI is the best modality for direct evaluation of the spinal cord, and the main fi ndings of an acute spinal cord injury include edema, hemorrhage, and transection. Spinal cord injury patterns revealed by MRI are important prognostic factors in patients with SCIWORA.
