Staged Spinal Cord Decompression Through Posterior Approach for Thoracic Myelopathy Caused by Ossification of Posterior Longitudinal Ligament

Abstract

Staged posterior decompression to eliminate anatomic factors inhibiting posterior shift of the thoracic spinal cord is the safest and the most reliable method of spinal cord decompression to treat thoracic OPLL myelopathy, so far. However, long-term results are required before the methods can be established.
