Illustration showing the measurement of anterior (HA), middle (HM), and posterior (HP) portions of fractured vertebral height; kyphotic angle (KA); Cobb angle; and vertebral heights 1 level above (upper) and below (lower) the index vertebra.

Change of the KA and Cobb angle during balloon kyphoplasty(−x±s). Note: Prone compared with preoperative, P < .05; balloon inflated compared with prone, P > .05; postoperative compared with preoperative, P < .05.

X-ray films of a typical patient: 69-year-old woman with a T12 vertebral compression fracture (wedge type). A, Preoperative standing lateral, HA, HM, KA, and Cobb were 20.20 mm, 24.57 mm, 17.27°, and 14.55°, respectively; B, intraoperative prone position lateral, HA, HM, KA, and Cobb were 25.33 mm, 25.23 mm, 8°, and 7°, respectively; C, intraoperative IBT inflated, HA, HM, KA, and Cobb were 25.33 mm, 25.23 mm, 8°, and 7°, respectively; D, postoperative standing lateral, HA, HM, KA, and Cobb were 24.82 mm, 24.91 mm, 8.56°, and 7.12°, respectively.
