Unilateral biportal endoscopic (UBE) decompression techniques is a percutaneous full endoscopic technique. It is performed through two separated small surgical wounds on either side of the spinous process. Unlike other endoscopic approaches, UBE is not confined by the working tube or the working channel. With continuous high-pressure normal saline irrigation and high-definition arthroscope, the surgeon can do very precise decompression in a clear and magnified surgical field.
UBE endoscopy in excellent alternative to microscopic assisted minimally invasive surgery. It developed to improve muscle preservation and other surrounding normal anatomical structures. Compared with open spinal surgery
