Abstract
Unilateral biportal endoscopic lumbar discectomy (UBE) is a minimally
invasive surgical procedure for treating lumbar disc herniation that is associated with
bony and soft tissue stenosis. This technique best suits surgeons who want to take
advantage of their great experience with the translaminar approach. It simplifies the
endoscopic learning curve by placing the endoscopic working cannula onto the
posterior spinal elements rather than placing it into the neuroforamen. This chapter
describes the technical and procedural aspects of UBE by providing a detailed
overview of the procedure, its indications, contraindications, surgical steps, and
potential complications. Furthermore, we highlight the advantages and limitations of
this innovative technique and discuss its established role in spinal surgery.
