Radiological evaluation of OVFs. V-deformity in OVF was evaluated by reference to Ha on lateral radiographs taken in SIT, DEC, and SUP. a, b, and c show lateral radiographs of a T12 OVF in SIT, DEC, and SUP, respectively, in the initial evaluation at 12 days after OVF onset, and d and e show radiographs taken in SIT and SUP, respectively, in the final evaluation at 3 months after OVF onset in an 81-year-old female. The difference in Ha between a, b, and c was > 1.0 mm and that between d and e was < 1.0 mm, demonstrating no V-mobility. OVF, osteoporotic vertebral fracture; V-deformity, vertebral deformity; Ha, anterior vertebral height; SIT, sitting position; DEC, lateral decubitus position; SUP, supine position; T12, 12th thoracic vertebra; V-mobility, vertebral mobility
