The Radiology of Osteoporotic Vertebral Fractures Redux

Abstract

When a low-energy fracture occurs, then osteoporosis has progressed to the point of bony structural failure. Because vertebral fractures are the commonest type of osteoporotic fracture, the correct identification of them becomes important for diagnosis, risk estimation, and management. However, there are no uniformly agreed criteria for their diagnosis. The purpose of this review was to examine the diagnostic radiological strategies available and suggest a coherent approach to diagnosis. Diagnosis had come to focus on comparative changes in vertebral dimensions. However, it has become apparent that mild reductions in vertebral height are of uncertain implication. The importance of structural damage in diagnosis has become recognized in parallel. Relative reductions in vertebral height may not be a necessary nor sufficient criterion by which to diagnose a fracture.
