Abstract

A new model of spinal cord injury (SCI) has been developed in the rat, which produces axonal and vascular injury within the spinal cord through lateral displacement of the vertebral column. An electromechanical feedback-controlled device produces the injury by displacing the vertebral column to the left hand side. The speed and lateral displacement is controllable by the user, and the resulting injury ranges from no histologically evident injury, to total disruption of the vertebral column with associated widespread axonal and vascular damage. Histological and immunohistological techniques were employed to correlate mechanical parameters with the extent of pathological injury of spinal cord. Axonal injury was most severe in the left lateral white matter, and vascular injury was concentrated in the gray matter.
