This retrospective observational study examines clinical outcomes in patients with lumbar spinal stenosis who underwent minimally invasive tubular decompression, with or without subsequent multisegmental percutaneous rhizotomy, at the General University Hospital of Valencia over 25 years (2000-2025). The purpose of the study is to determine whether decompression alone provides sufficient long-term symptom improvement or whether additional spinal fusion (transfacetal TLIF) is needed in specific patient subgroups. By analyzing real-world data from routine clinical practice, this study aims to identify clinical, radiological, and demographic factors associated with the need for fusion surgery, particularly in older adults who may benefit from less invasive treatment strategies. No new interventions are performed as part of this study, and all data are obtained from existing medical records.
