Trauma
Trauma to the spine refers to injury that has occurred to bony elements, soft tissues and/or neurological structures. The two things that surgeons are most concerned about, in the case of spinal trauma, are instability of the vertebral column and actual or potential neurological injury.
Stability to the spinal column can be compromised when bony elements are injured or there is disruption to soft tissues such as ligaments. Instability causes the back to become unable to successfully carry normal loads, which can lead to permanent deformity, severe back pain and in some cases catastrophic neurological injuries. Most often the instability comes from a fracture in one of the bony parts of the vertebra, specifically the vertebral body, the lamina or the pedicles.
In the case of trauma, dislocations and fractures happen simultaneously and can result in a very unstable spinal column. They can occur in any region of the spine and are associated with a degree of neurological injury. A surgeon needs to restore the mechanical stability of the spine to try and prevent more neurologic injury, progressive deformity, back pain or prolonged incapacitation pain.
