If a compression fracture of the 12 thoracic vertebrae is not serious, it is certainly much more serious than a soft tissue injury. The compression fracture itself also has a degree of severity, like the whole vertebral body if not more than 1/3 of the compression fracture, relatively light, can be solved by conservative treatment. If the height of the vertebral body compression exceeds 1/2, it will lead to a certain compression of the nerves behind the spinal canal, which is very serious in comparison, and there will be urinary and fecal dysfunction or numbness and pain in both lower limbs. If the compression fracture is more serious, the entire vertebral body has been flattened, may directly lead to double lower limb paralysis, which is the most serious kind. Therefore, the specific results of the examination and the current clinical symptoms should be integrated to determine the seriousness of the situation.
