Clinical and Radiological Outcomes of Anterior Approach Microscopic Surgery for the Pincer Mechanism in Cervical Spondylotic Myelopathy

Figure 1

Female, 75-year-old, numbness of right limb, and difficulty in walking for 1 year. Preoperative JOA score was 12. The cervical MR scanning showed C5/6-disc herniation with posterior wrinkled and incrassated ligament Flava, leading to pincer spondylotic myelopathy. Anterior and posterior occupying rates were 36.4% and 36.4% (a). The lateral cervical X-ray showed intervertebral height loss in C5/6. Preoperative Cobb’s angle was 9.7° (b). The posterior compression was relieved at the same time by anterior decompression and fusion (ACDF), and the spinal cord was decompressed sufficiently (c). The intervertebral plate and body height were increased after the operation. Postoperative Cobb’s angle was 29.1° (d). Postoperative JOA score was 17 at 6th-month follow-up.
