- Fig 1.
CT scan of a thoracic vertebra following KP. There was a lateral blowout fracture of the vertebra caused by balloon inflation and a large cement leak (arrow) into the mediastinum. The patient had severe pain requiring hospitalization and protracted analgesic therapy for weeks following therapy. (From JM Mathis. Percutaneous vertebroplasty. AJNR Am J Neuroradiol 2003; 24:1697–1706; by permission.)
- Fig 2.
Radiograph following PV and KP, showing small, asymptomatic cement leaks at both levels. The PV level (above) had a small cement leak into an adjacent vein (arrows). The KP level (below) had small cement leaks into both adjacent disk levels (arrowheads).

A, Compression fracture with anterior cleft before KP. Endplates are marked (arrows). The height is estimated at 50% of the height of the adjacent level above.
B, Fluoroscopic image showing balloon inflation during KP.
C, After cement injection, the height gain is approximately 4 mm, or 25% of a vertebral height (when compared with the adjacent level above). There was essentially no kyphosis to start with, and this vertebrae had a cleft originally and therefore would be expected to be a good candidate for height restoration.
- Fig 4.
A, Radiograph of a compression fracture and 18° of kyphosis.
B, Following PV, there is modest height gain, estimated at 3–4 mm, and a reduction in kyphosis to 9°. (From JM Mathis. Percutaneous vertebroplasty. AJNR Am J Neuroradiol 2003; 24:1697–1706; by permission.)
