Cystic changes within the endplates adjacent to the implants. Cystic changes within the endplates adjacent to the implants. A, Five months after surgery in a 62-year-old woman, CT scan shows cystic changes (arrows) in the endplates at the L5–S1 level on an axial image. B, Twenty-one months after the application of posterior instrumentation, CT scan shows that the cystic changes are much less prominent as the fusion is progressing to solid bony union. Alan L.
