the spine is part of the the central nervous system, it connects all the nerves to the brain (basically) so if the spine is injured, it could mess up his nervous system, causing his legs to be paralyzed

the nerves in his legs communicate with the brain by traveling through the spinal cord. once this bond is broken his brain cannot send messages to his lower body any longer.
