Spinal cord injuries typically are distinguished by the level of injury within the spinal column, whether it occurs at vertebrae in the cervical, thoracic, lumbar, or sacral region. Thus, cervical injuries can occur at levels C1–C8, thoracic injuries at levels T1–T12, lumbar injuries at L1–L5, and sacral injuries at S1–S5. Cervical spinal cord injuries typically result in quadriplegia (or tetraplegia), because they cause weakness or paralysis in the arms and legs.
