Abstract

Spinal cord Injury following intervertebral disk herniation is a combination of a concussive and a compressive injury. Concussion of the spinal cord acutely damages meninges, blood supply, and neural tissue. This constitutes the primary injury. Following the primary injury, a cascade of vascular, biochemical, and cellular events results in additional secondary injury to the spinal cord. Compression of the spinal cord following intervertebral disk herniation may result from a mass of herniated disk material and hematoma within the vertebral canal (extradural compression) or spinal cord swelling within a rigid dura mater (intramedullary compression). Knowledge and understanding of the pathophysiology are Important for appropriate diagnosis and treatment of spinal cord injury.
