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.
