Comparison of ODI scores for leg pain between the SELD and PEN groups at preoperative weeks 4, 12, and 24; statistically significant differences were observed at 24 weeks postoperatively (). ODI = Oswestry Disability Index; SELD = trans-sacral epiduroscopic laser decompression; PEN = percutaneous epidural neuroplasty; POD = postoperative duration.
