Magnetic resonance imaging in cervical spine trauma.
The ability of magnetic resonance imaging (MRI) to diagnose locked facets was examined in a series of six patients with traumatic cervical spine fractures. Plain films, computed tomography, and magnetic resonance scanning were done immediately following injury. Cord edema, contusions, and acute disc herniation were well visualized on magnetic resonance images. Magnetic resonance proved to be equally effective in diagnosing unilateral and bilateral locked facets, and demonstrated the disruption of the posterior longitudinal ligament (PLL) with clarity. The magnetic resonance diagnostic criteria of locked facets, herniation of intervertebral discs, and rupture of the posterior longitudinal ligament are described. Besides permitting direct visualization of the spinal cord, MRI may have a role in the diagnosis and management of acute bony injury to the cervical spine.
