Biportal endoscopic transforaminal thoracic interbody fusion for the treatment of thoracic myelopathy.

Abstract

Biportal endoscopic spine surgery independently controls two hands, similar to microscopic surgery, and utilizes a broader working space that is not disturbed by retractors under clear-magnified endoscopic vision. These advantages facilitate successful neural decompression and safe transforaminal interbody fusion, even in patients with thoracic spondylotic myelopathy. A wide laminectomy and precise total facetectomy, in conjunction with partial pediculotomy, establish a secure transforaminal space for cage insertion. Endplate preparation and cage insertion were performed without retracting the spinal cord under direct endoscopic vision. Biportal endoscopic transforaminal thoracic interbody fusion can be a feasible technique for treating thoracic spondylotic myelopathy at the thoracolumbar junction levels.
