Neurologic injury to the conus medullaris after burst fractures can result from compression of the spinal canal at the thoracolumbar junction. Injury severity can vary from subtle bowel and bladder findings to profound sensory and motor deficits. Although complete injuries have a poor prognosis, incomplete conus lesions have a good chance of improving one to two Frankel grades. In addition, bowel and bladder recovery is likely, especially if canal decompression is achieved early. Stabilization of the spine can be effected by anterior, posterior, or combined methods. Anterior decompressive maneuvers have demonstrated the most effectiveness in canal clearance.
