C4 to C7 DCS with recurrent myeloradiculopathy 6 years after C4-C6 anterior cervical decompression and fusion (ACDF). a Preoperative radiograph shows DCS at C4-C7 levels. b Preoperative MRI of this 49-year-old female shows severe compression of the spinal cord at C4-C6 levels. c Radiograph after initial surgery shows ACDF at C4-C6. d Radiograph 6 years after initial surgery shows osseous fusion of C4 and C6 and development of adjacent-segment degeneration (ASD) at C6-7. e MRI at 6-year follow-up shows development of ASD and spinal cord compression at C6-7. f Radiograph after the second surgery shows ACDF at C6-C7. ACDF, anterior cervical decompression and fusion; ASD, adjacent-segment degeneration; DCS, developmental canal stenosis, MRI, magnetic resonance imaging
