A 55-year-old woman underwent C3-6 anterior diskectomy with fusion, posterior instrumented fusion with C2, C7 pedicle screws and C3-5 lateral mass screws, and posterior decompression with C3-6 laminoplasty. a Preoperative X-rays show fixed cervical kyphosis with C2-7 marked spondylosis. b Preoperative midsagittal T2-weighted magnetic resonance imaging shows that C2-7 stenosis with spinal cord compression. c Postoperative X-rays show that cervical curvature has been restored and the fusion structure is solid. d Postoperative 6 months computed tomography scans demonstrate that hinge side fusion bed union (black arrows). e Postoperative 12 months midsagittal T2-weighted magnetic resonance imaging shows patent spinal cord without compression
