Figure 2

The 76-year-old female patient received PSF (Th10 to ilium). (a) Immediate postoperation whole spine PA standing radiograph demonstrates normal coronal alignment. (b) Immediate postoperation whole spine lateral standing radiograph demonstrates normal sagittal alignment. (c) Immediate postrevision whole spine lateral standing radiograph demonstrates normal sagittal alignment. (d) PA view at readmission shows moderate PJK (PJA 18.2 deg.). (e) T1WI around the upper instrumented vertebra (UIV) area shows bone destruction of the UIV vertebra. (f) T2WI around the UIV area shows fluid correction around the UIV+1 vertebra.
