What is UBE?

 

Unilateral Biportal Endoscopic spine surgery overcomes the limitation of central canal stenosis, lateral canal stenosis and foraminal stenosis due to a wide range of access angles resulting in effective circumferential and focal decompression of the spinal canal without damage to the structural integrity of the spine with preservation of muscular and ligamentous attachments this approach through the spatium intermuscular and preserves the medial branch of the dorsal ramus thereby preventing distraction injury. This endoscopic approach allows for accessing the foramen both from the contralateral side posteriorly and the extra foraminal side  (paraspinal extraforaminal approach) just giving flexibility to treating all types of stenosis. UBE is useful in patients of instability lysis and lysthesis as a minimal access fusion approach.
