A 1-centimeter nodule in the lumbar spinal canal is a phenomenon that occurs primarily in the lumbar spine as a result of abnormal growth and development of a physiologic structure. Imaging is called Schmoe’s node. 1. The cartilaginous plate of the vertebral body is ruptured, and the medulla protrudes into the vertebral body through the fissure, resulting in a semicircular defect shadow in the vertebral body, which is known as Schmidt’s node. If it is not combined with protrusion toward the posterior margin of the vertebral body, there may be no clinical signs of nerve root compression. 1. Under normal physiologic conditions, the upper and lower edges of the vertebral body are mainly covered by cartilage. When the lumbar vertebrae suffer from some kind of injury, developmental defect, or degenerative changes, the vertebral endplates will rupture. The nucleus pulposus of the lumbar intervertebral disc enters the vertebral body along with the ruptured position, forming the pressure of the nucleus pulposus on the bone and causing pain in the lower back. 2. Simple lumbar vertebral nodule phenomenon, the patient does not appear in the daily limb numbness, radiating pain and other neurological stress, you can not be treated first, daily appropriate for some lumbar back muscle rehabilitation training can be. From the CT examination, the lumbar intervertebral disc did not have obvious abnormalities, it is recommended that patients choose conservative treatment. 3. If the patient has obvious localized nerve compression, it is recommended that the patient undergoes surgery. After surgery, patients should pay attention to bed rest, and when the local symptoms are effectively recovered, they can do some auxiliary lumbar back muscle rehabilitation training to promote the effective recovery of symptoms. Lumbar spinal tuberculosis may also have other causes, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
