Paraplegia is the loss of sensation and movement in legs and in part or all of the trunk, usually resulting from an injury to the spinal cord below the neck. Quadriplegia (also Tetraplegia) is paralysis of all four limbs (from the neck down) resulting from injury to the neck. Fractures or compression of the Vertebrae, which cause permanent damage to the spinal cord may lead to loss of sensation, movement, pain management, bladder and bowel control, as well as affecting sexual function.
