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

Abstract

Mohammad Bagher Owlia and Pouran Farahifard

“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”.
