A 52-year-old male developed numbness and weakness in his four extremities for 2 years, together with unbalance gait for 2 months. Preoperative radiographs showed that the sagittal alignment of the cervical spine was physiologic lordosis (a, b), and the magnetic resonance imaging scans showed that the spinal cord compressed at C3/4, C4/5, C5/6 (c, d). He was performed with ACHDF including 1-level corpectomy plus 1-level discectomy without surgery-related complications. After operation, his JOA scores improved from 9.7 preoperation to 13.6 postoperation. Postoperative lateral and flexion-extension cervical radiographs showed that the cervical kyphosis was corrected (e, f) and the graft was fused at 1-year follow-up (g, h)
