Biportal Endoscopic Laminectomy and Removal of Thoracic Ossification of Ligamentum Flavum

Abstract

Ossification of the ligamentum flavum (OLF) in the thoracic spine is a known cause of thoracic myelopathy, with a higher prevalence among East Asian populations, particularly in Koreans, Japanese, and Chinese, compared to other groups [1, 2]. Early diagnosis and timely surgical decompression are crucial for improving the functional outcomes of thoracic OLF. Surgical intervention is essential and should be performed promptly once symptoms appear. Treatment options vary widely, ranging from traditional open laminectomy to minimally invasive endoscopic decompression [3, 4].
