The effects of spinal cord injury induced by shortening on motor evoked potentials and spinal cord blood flow: an experimental study in Swine.
Spinal cord injury due to spinal shortening is disastrous, but the amount that the spine can be shortened without injury is unknown. We assessed spinal cord injury and changes in spinal cord blood flow after spinal shortening in swine. ⋯ Spinal shortening of =104.2% of one vertebral body height at the thoracolumbar level caused spinal cord injury, but shortening of =73.8% did not result in injury. swine.
