Abstract: The surgical anatomy of the lumbosacral spine junction is different from that of the other rostral levels. Its unique anatomy makes the L5 exiting nerve vulnerable to compression. The limited space might restrict surgical decompression of the L5 exiting nerve. Therefore, it is mandatory to recognize the anatomical features around the L5 exiting root. This narrative review introduces the essential surgical anatomy regarding the L5-S1 neural foramen and extraforaminal structures.
