A revision case of a 61-year-old man 12 months after initial posterior laminectomy. a, b The anterior–posterior and lateral images showed the loss of cervical lordosis after the initial laminectomy. c, d The CT scan showed that there was a continuous type of OPLL, and only a semilaminectomy with one-sided lateral mass fixation was done in the initial surgery. e The intraoperative photo showed that after installation of the intervertebral cages and anterior cervical plate, we used 1-mm Kerrison rongeurs to remove the posterior vertebral wall on the bottom of the troughs for isolation of the VOC (arrows). f, g The postoperative anterior–posterior and lateral images showed good internal fixation position and improved cervical lordosis. h The CT scan showed that the VOC was hoisted forward, and the cervical spinal canal was obviously wider than it was before
