The fracture of the lumbar spine may result in nerve compression. The spinal canal is composed of the spinal nerve, and the intervertebral foramen also has nerve roots that emanate from the spinal cord, which are directed to the periphery to govern the movement of the muscles. If the lumbar spine is severely fractured, the normal structure of the lumbar spine will be abnormal and the lumbar spinal canal or intervertebral foramen will be structurally altered, which can cause symptoms of nerve compression. When there is trauma, orthopedics need to ask the patient’s symptoms in detail, nerve compression more lumbar, leg pain or numbness, need to improve the lumbar plain film, nuclear magnetic, CT examination to clarify the diagnosis, you can also check the electromyography and other understanding of nerve damage.
