Mohs’ nodes, so-called Schmidt’s nodes, are formed after the degeneration of the vertebral endplate cartilage, and the intervertebral disc tissues are embedded in the vertebral body through the damaged and ruptured cartilage fissure. Schmidt’s tubercle occurs under the cartilage of the vertebral endplates, which is a manifestation of degeneration of the vertebral endplate cartilage, and can be diagnosed by X-ray or MRI. X-ray lateral view shows a rounded defect at the upper or lower edge of the vertebral body, which can be accompanied by osteosclerotic shadows in the defect area; in the sagittal view of MRI, the rounded shadows are seen at the upper or lower edge of the vertebral body, which are roughly in line with the disc tissues. Schmidt’s nodes are usually asymptomatic, but in some cases they may cause back pain due to inflammation caused by the nucleus pulposus protruding into the vertebral body, which usually resolves spontaneously after the inflammation subsides.
