What kind of physical injury could cause a child paraplegia?

Seat belt syndrome: A kid that graduates too soon to a seat belt is at tremendous risk of paraplegia in a frontal impact crash.As the body is thrown forward, the belt slides up over the pelvis and compressed the abdominal contents.The shock wave travels back to the spinal cord and bends the vertebrae, often cracking them. The result can include rupture of abdominal organs, immediate paraplegia and a broken back.

Spinal cord injury: Injury to the spinal cord at the chest level and down result in paraplegia. (loss of motor and sensory function). Also dysfunction of the bowel and bladder is possible. The treatment is different from patient to patient.
