(a) Preoperative radiograph showing C3–C6 segment degeneration. (b) Preoperative sagittal T2W1 MR image revealed C34, C45, and C56 spinal cord compression. (c) Postoperative plain radiographs demonstrating adequate cervical lordosis and no cage subsidence 3 months (1) and one year (2) after ACDF. (d) Sagittal T2W1 MR image showing no spinal cord compression one year after ACDF. (e) Postoperative sagittal reconstruction CT image demonstrating C3–C6 fusion and no lucency between cages and endplates at one year postoperatively.
