Note:—PVP level indicates treated level of percutaneous vertebroplasty; Fx, fracture; Ad, adjacent.
* Vacuum cleft with fluid or air in the PVP level.
† Interval from the date of PVP to the follow-up MRI in which new symptomatic compression fracture was depicted.
‡ Disk rupture with migration toward the new adjacent compression level in the follow-up MRI.
