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.
