The demonstration and significance of neural compression after spinal injury

Standard metrizamide myeLography and CT myelography can accurately and safely define neural compression after a spinal injury. A lateral C1-C2 spinal puncture and a radiolucent fracture board reduce movement of the spine, and by injecting metrizamide in an isotonic concentration and by limiting the amount of contrast above a block, the risk of seizure is minimized. This capability for directly determining neural compression has important implications for the treatment of spinal fractures, and the significance of persisting posttraumatic neural compression is discussed. We believe neural compression should be the primary indication for surgical decompression after spinal injury and that evaluation for it should now be a standard part of the examination of patients with spinal fractures with potential for neurological recovery.
