Fig. 2

The four measurement points on the vertebral images were set at the anterior superior (a1), anterior inferior (a2), posterior superior (p1), and posterior inferior (p2) margins of the vertebral body. Ha and Hp vertebral dimensions were defined as the distances from a1 to a2 and from p1 to p2, respectively. WA was defined as the angle between two lines through a1 and p1 and through a2 and p2. WR (%) was calculated as Ha / Hp × 100 (%). Lateral radiographs of an osteoporotic vertebral fracture are shown in the (a) non-weight-bearing position and (b) weight-bearing position. The shadowed area indicates the collapsed part of the vertebral body in the weight-bearing position (V-mobility).
