What is a spinal cord injury?

Back to overview

Spinal cord injury is the consequence of a traumatic or ischemic event, which results in damage to cells within the spinal cord or a severance of the nerve tracts that relay signals up and down the spinal cord. The most common type of SCI is caused by contusion injury (induced by bruising of the spinal cord). Other types of injuries include lacerations (severing or tearing of nerve fibres such as damage caused by a gunshot wound).
