Schmorl's nodes were observed in 76 (19%) of 400 patients with lumbar symptoms, and in 10 (9.4%) of 106 control patients. In the lumbar group, the highest incidence was 57%, in the second decade of life, and the lowest was 5%, in the sixth decade of life. Using MRI, among both groups, a total number of 218 Schmorl's nodes were observed at 170 disc levels; however, plain x-ray revealed only 73 (33%) of them. There were associated posterior disc herniations at 39 disc levels in 30 cases (39%), most of which were at the L4/5 level. The ratio of the cases showing only Schmorl's nodes to those with associated disc herniations at the same level increased markedly with age. Three of the four teen-aged patients with multiple Schmorl's nodes at four or more disc levels had a history of hard sports. Schmorl's nodes, therefore, appear to be a type of vertical disc herniation, and to be an important pathognomonic condition, especially for young people.
