Images from a 65-year-old man who underwent three-segment spinal fusion. a Preoperative radiograph. b 1-week postoperative radiograph. c MRI revealing the development of symptomatic adjacent segment disease at 3 years and 5 months postoperatively. Preoperatively, the pelvic incidence to lumbar lordosis mismatch (PI-LL) was − 1.6°. Postoperatively, the PI-LL was 13.7° and the change in lumbar lordosis was 15.3°. Patients (age > 60) with a change in lumbar lordosis of > 10° were significantly more likely to develop adjacent segment disease
