Percutaneous Adhesiolysis Versus Transforaminal Epidural Steroid Injection for the Treatment of Chronic Radicular Pain Caused by Lumbar Foraminal Spinal Stenosis: A Retrospective Comparative Study

To investigate the efficacy of percutaneous adhesiolysis (PA) compared to fluoroscopy (FL)-guided transforaminal epidural steroid injection (TFESI) in patients with radicular pain caused by lumbar foraminal spinal stenosis (LFSS) by assessing pain relief and functional improvement at 4 and 12 weeks post-procedure. This retrospective study included 45 patients who underwent PA or FL-guided TFSEI for radicular pain caused by LFSS of at least 3 months' duration. Outcomes were assessed with the Oswestry Disability Index (ODI) and Verbal Numeric Pain Scale (VNS) before the procedure and at 4 and 12 weeks post-procedure. A successful outcome was defined by >50% improvement in the VNS score and >40% improvement in the ODI score. ODI and VNS scores improved 4 and 12 weeks post-procedure in both groups. Statistically significant differences between groups were observed in ODI and VNS at 12 weeks (p
