Clinical Results and Complications of Circumferential Spinal Cord Decompression Through a Single Posterior Approach for Thoracic Myelopathy Caused by Ossification of Posterior Longitudinal Ligament

Abstract

Despite circumferential spinal cord decompression through posterior approach for thoracic OPLL providing effective neurologic recovery, there was a high rate of complications such as postoperative neurologic deterioration. Risk factor analysis shows that multiple level circumferential decompression of 5 or more vertebral levels to be associated with unfavorable surgical outcome.
