Images from a 71-year-old woman who underwent one-segment spinal fusion. a Preoperative radiograph. b 1-week postoperative radiograph. c MRI revealing the development of symptomatic adjacent segment disease at 1 year and 3 months postoperatively. Preoperatively, the pelvic incidence to lumbar lordosis mismatch (PI-LL) was − 35.9°. Postoperatively, the PI-LL was − 37.7° and the change in lumbar lordosis was 1.8°. Patients (age > 60) with a PI-LL of > 20° were significantly more likely to develop adjacent segment disease
