A catastrophic injury is a severe injury to the spine, spinal cord, or brain, and may also include skull or spinal fractures. This is a subset of the definition for the legal term catastrophic injury, which is based on the definition used by the American Medical Association.
Injuries that are considered catastrophic, due to the enormous impact they have on the lives of the individuals who experience them, include the following: brain injury, spinal cord injury, accidental amputation, severe burns, multiple fractures, or other, neurological disorders.
Direct injuries are caused by forces generated from outside the body. Indirect injuries are caused by a force from within the body. Overuse injuries result from excessive and repetitive force over extended periods of time.
