A 57-year-old female patient at the time of presentation with lumbar spondylolisthesis. Image workup demonstrated responsible lesion at L4/5. The L4/5 were treated with unilateral pedicle screws, and the cage was implanted anteriorly. At the final follow-up, her ODI, VAS lumbar and leg pain scores had decreased from 50%, 5, 5 to 30%, 2, 3 respectively. Preoperative anteroposterior (A) and lateral (B) radiographs show typical radiological findings of lumbar spondylolisthesis. Anteroposterior (C) and lateral (D) radiographs obtained immediate postoperatively and the latter illustrated an anterior cage position
