Paraplegia is the result of spinal cord damage. The spinal cord is located in the spinal canal and is part of the central nervous system. It passes on information between the brain and the body. If damage occurs, the line is interrupted and usually cannot be restored. It corresponds to damage in the thoracic region or below and means paralysis of both legs. This is also referred to as low-level paralysis. The upper extremities remain functional; in most cases, the respiratory muscles are not or only slightly affected. Fractures of the spine, usually as a result of an accident, cause paraplegia. Due to this, vertebral bodies move and the spinal cord is squeezed. Tissue swelling and bruising can lead to damage to the spinal cord. In the process, a scar is formed at this point, but the original connections are broken and cannot be restored. Muscular failure in the form of paralysis is the most obvious symptom of paraplegia. The extent depends on how badly the spinal cord is damaged.
