Historical Schmorls Node: Time to Differentiation and Renaming (A Mini- Review)

Abstract

Abstract"Schmorl's nodes" (SN) are lytic lesions at endplates which are believed to be due to the herniation of the nucleus pulposus through the cartilaginous endplate into the body of a vertebral endplates. Our observations disclose the fact that all Schmorl's nodes are not single entities and a subset of SNs seems to be a discrete clinical condition with similar (but not identical) imaging manifestations. They share many features of seronegative spondyloarthritis. We called them "Owlia's nodes".
