OLF is the most common cause of thoracic spinal stenosis. The most common surgical procedures involve semi\u2010lamina or full\u2010lamina resection and decompression. However, considering the anatomical structure of the thoracic spinal canal and the combination of OLF, traditional surgery has higher risks, more complications, and greater technical requirements. In the past ten years, with the development of endoscopic technology, spinal endoscopy has been increasingly applied for the treatment of intervertebral disc herniation and spinal canal stenosis. The present study demonstrated the effectiveness of visual trepan decompression under spinal endoscopy used for patients with single segment OLF. This surgical procedure had many advantages, including a shorter operation time, minimal trauma, less expenditure, and better functional recovery over the conventional open surgery.<\/jats:p>","DOI":"10.1111\/os.12538","type":"journal-article","created":{"date-parts":[[2019,10,30]],"date-time":"2019-10-30T00:57:43Z","timestamp":1572397063000},"page":"906-913","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Using
