“…The fourth anatomical interval, due to its overall outer position, allows for a complete lateral view of the entire vertebral pedicle area during the operation, that is, a direct view of the intervertebral foramen and the Kambin triangle, making it more convenient for the operating surgeon to determine the scope of the foraminotomy, thus providing a more complete exposure of the lateral recess compared to other anatomical intervals in UBE surgery. At the same time, due to the outer position of the portal, UBE surgery in the fourth anatomical interval can also better handle the Far-out syndrome (lesion located in the region formed by transverse processes, sacral wings, and iliolumbar ligaments), 60 further expanding the surgical indications. In addition, UBE surgery in the fourth anatomical interval can more conveniently observe and treat lesions near the anterior aspect of the vertebrae, such as extreme lateral disc herniation, reducing the difficulty of this type of surgery.…”

Study Design Review. Objective Unilateral Biportal Endoscopy (UBE) is a minimally invasive surgery that is gaining recognition and being employed in clinical practice. Nevertheless, the precise method for determining UBE portals’ location varies depending on the originator’s preferences or the anatomical structure’s proximity to the portal positions. Consequently, the relationship among UBE portals' locations is messy. This study aims to elaborate on the specific portal localization and explore the positional association and commonality among different UBE approaches’ portals. Methods The following keywords are used to search in the PubMed, Ovid, Web of Science, ScienceDirect, SpringerLink, Scopus, CNKI, and Wanfang database: “Biportal endoscopic spinal surgery”, “Two portal endoscopic spinal surgery”, “Percutaneous biportal endoscopic decompression”, “Unilateral biportal endoscopy”, “Irrigation endoscopic discectomy”, “UBE” and “BESS”. Results After screening, 29 pieces of literature are included. The study summarizes different UBE approach portal localizations, categorized by fusion or non-fusion surgery and pathological classification. The study presents an inaugural method for categorizing the lumber into four surgical intervals based on bone landmarks and assigns different UBE approaches to the appropriate intervals based on their characteristics, making the selection of UBE surgical approaches’ portal locations more flexible. Additionally, the study provides an overview of the indications, complications, and distinct benefits associated with each interval, further refining the novel UBE portal interval localization method. Conclusion The study clarifies the interrelationship and commonality between the portals of different UBE approaches and proposes a new UBE portal interval localization method to enhance surgeons’ understanding and proficiency in UBE procedures.
