Figure 1

The 72-year-old female patient received PSF (Th10 to ilium). (a) Immediate postoperation whole spine posterior-anterior (PA) standing radiograph demonstrates normal coronal alignment. (b) Immediate postoperation whole spine lateral standing radiograph demonstrates normal sagittal alignment. (c) Immediate postrevision lateral view shows normal sagittal alignment. (d) PA view at readmission shows severe PJK (PJA 33.4 deg.). (e) T1-weighed MR image (T1WI) around the UIV area shows bone destruction of both UIV and UIV+1 vertebra.
