SQ mild grade OVFs. (A,B) are the same image. The 6 points were on the vertebra with mild OVF. (B) The measured anterior and posterior heights of the deformed vertebra (unit in pixel number), as well as the anterior height of an adjacent upper vertebra. (C) Star denotes a mild OVF. We consider both these two deformed vertebrae have height less <20%. (A,B) are modified from (25). (C) is modified from https://www.iofbonehealth.org/what-we-do/training-and-education/educational-slide-its/vertebral-fracture-teaching-program.
