How I do it: minimally invasive surgical decompression for lumbosacral extraforaminal stenosis (Far-Out Syndrome)

Year: 2025

Type: article

Abstract: BACKGROUND: Accurate diagnosis of extraforaminal entrapment of the L5 nerve root, commonly referred to as "far-out syndrome," is challenging due to its unique anatomical characteristics, which differ from those of other lumbar regions. Inadequate decompression may lead to poor outcomes. METHOD: A minimally invasive paraspinal approach utilizing a tubular retractor was used to decompress extraforaminal entrapment of the L5 nerve root. Procedures and discussions regarding indications, diagnoses, surgical endpoints, and ways to avoid complications were described. CONCLUSION: Adequate decompression requires sufficient resection of the L5 lower vertebral body bony spur, transverse process, and sacral ala as a ventral margin.
