The Amount of Bone Mineral and Schmorl's Nodes in Lumbar VertebraeHANSSON, TOMMY, MD*; ROOS, BENGT, PhD†Spine: April 1983 - Volume 8 - Issue 3 - p 266–271 Original Article: PDF Only Buy Abstract Author InformationAuthors The bone mineral areal content and the ultimate compressive strength were determined in 109 lumbar vertebrae from 36 subjects. The bone mineral areal content was related to the number, shape, and localization of the Schmorl's nodes detected in the x-rayed and sectioned vertebral bodies. One type of node, irregular in shape and localization, occurred only in the vertebrae with low bone mineral areal content values and thus in vertebrae with relatively low compressive strength. A second type of Schmorl's nodes, regular in shape and localization, did not reflect any general weakness of the vertebral bodies. *Departments of Orthopaedic Surgery, Sahlgren Hospital, University of Göteborg, Sweden. †Departments of Radiation Physics, Sahlgren Hospital, University of Göteborg, Sweden. © Lippincott-Raven Publishers.
