Abstract:
As the gun shot wound outside the vertebral canal of the spine, what is the mechanism of spinal cord injury (SCI) ? We put transducers at the cauda equina or spincal cord in the vertebral canal to estimate intracanal pressure during sun shot injury at the spine. The results showed that: in penerating wound of vertebral canal the pressure was between17?10~5Pa and 56?10~5Pa and the spinal cord was brocken directly by the bullet. In pericanal wounds, such as lamina, root of spinous process or vertebral body, the pressures were at 33. 3～95?10~5Pa. All of these wounds were complete SCI. In perispinal wounds such as tip and interspace of spinous process, anteror border of vertebral body, they were incomplete SCI, the pressures were usually 10?10~5Pa. If the intracanal pressure was not determined determinafted, there was usually no SCI.
