About Spinal injuries
Most injuries to the spinal cord don't completely sever it. An injury is more likely to cause fractures and compression of the vertebrae, which then crush and destroy the spinal nerve tracts. The prognosis is variable between almost complete recovery and complete paralysis.
Depending on the level of the injury, various paralysis patterns occur: injuries in the neck area lead to paralysis of the hands, arms, torso and legs (known as tetraplegia). Injuries in the thoracic, lumbar or sacral area in turn cause paralysis of the legs, but sometimes also the torso and pelvic region (internal organs). This form is called paraplegia.
While sensations can often still be felt with incomplete spinal cord injury, movements are no longer possible. Medical devices such as orthoses support the body in such cases - sometimes the exact opposite applies: movements are possible, but the patient no longer feels anything in the affected region.
