Images from a 56-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 4 years and 6 months postoperatively. Preoperatively, the pelvic incidence to lumbar lordosis mismatch (PI-LL) was − 8.5°. Postoperatively, the PI-LL was 0.5° and the change in lumbar lordosis was 8°. Patients with a PI–LL of < 10° and a change in lumbar lordosis of < 10° were significantly less likely to develop adjacent segment disease
