An injury to the thoracic or lumbosacral cord would likely result in neural deficits at the trunk, genital area, and lower extremities. Specific syndromes, such as Brown-SÃ©quard syndrome and anterior cord syndrome, may affect a major part of the spinal cord. See Overview for more detail.
The spine is made up of strong bones called vertebrae. A vertebra can break just like any other bone in the body. When the vertebral body collapses, it is called a vertebral compression fracture. These fractures happen most commonly in the thoracic spine (the middle portion of the spine), particularly in the lower part.steoporosis is a common cause of compression fractures in the spine. This disease thins bones, often to the point they become too weak to bear normal pressure. They can eventually collapse during normal activity, leading to a spinal compression fracture.
