FIG 1. Diagrammatic representation of lateral views of the spine and spinal fracture, pre- and post-vertebroplasty, are represented (1 indicates height of the control "normal" vertebral body; 2, height of the vertebral body pre- and postvertebroplasty; 3, kyphosis angle as according to the method of Cobb, as described by Teng et al [11]; 4, wedge angle as described by Teng et al [11]).

FIG 2. Height improvement with prone positioning and vertebroplasty.
A, Prevertebroplasty, T-12 osteoporotic fracture, with subtle anterior vertebral body cystic cavity, prone position, lateral (1). Midvertebral height of the fracture is compared with the adjacent normal appearing vertebral body height (2).
B, Postpercutaneous vertebroplasty, prone, lateral, with improvement in height. The improvement in height by using the method of Leiberman et al, is approximately 30%. The improvements of the wedge angle and kyphosis angle, by using the method of Teng et al are eight and 7°, respectively.
