Thirteen FCs were decompressed (no adverse events) NRSleg pain and ODI improved from 6.85 ± 0.69 and 65.08 ± 7.95 preoperatively to 1 ± 0.91 and 13.46 ± 5.19 at 1-yr follow-up, respectively.
Similar results could be observed for the long-term follow-up subgroup (50%, <i>n</i> = 33) with significantly less back pain (NRS 3.94 versus 7.0; <i>p</i> < 0.0001) and leg pain (visual analog scale 3.14 versus 5.39; <i>p</i> < 0.002) postoperatively.
Outcomes measured included the Oswestry Disability Index (ODI), NRS scales for back and leg pain (NRS-B/NRS-L), CSORN questions pertaining to patient satisfaction with surgery and whether or not the surgery met expectations.
Clinical outcomes were assessed using numeric rating scale for back and radiating leg pain (NRS back and leg), Oswestry Disability Index (ODI), and modified MacNab criteria at 1 month (short-term follow-up) and at least 12 months (long-term follow-up) after PELD.
