A, Lateral radiograph of the spine showing a moderately compressed vertebra (black arrow).B, Postvertebroplasty, there are large leaks of cement (black arrows) into the adjacent disk spaces.C, Six months later, the patient returned with a second fracture (white arrow). This fracture is not an adjacent level. Adjacent levels did not fracture despite the large disk leaks. John M.
