Abstract
INTRODUCTION: Low back pain (LBP) from superior or middle cluneal nerve entrapment has been addressed surgically. We recorded patient satisfaction with this treatment. METHODS: We included 22 consecutive patients who had undergone surgery for unilateral cluneal nerve entrapment (superior: n = 17, middle: n = 5). The numerical rating scale (NRS) for LBP, the Oswestry Disability Index (ODI) score, and the EuroQOL 5-dimension, 5-level (EQ-5D-5L) scale before and 6 months after the operation were compared. Using these scores, the treatment outcome was compared with the patients' preoperative expectations. RESULTS: LBP was ameliorated in all 22 patients; their NRS, ODI, and EQ-5D-5L were significantly improved after surgery. Surgical satisfaction based on the postoperative NRS scores was recorded as 8.8 ± 1.1 (range 7-10). While the postoperative was significantly better than the expected NRS, the postoperative ODI was significantly higher than expected by the patients (both: p < 0.05). There was a moderate correlation between the postoperative NRS and ODI and postoperative patient satisfaction. CONCLUSION: Patient satisfaction with the surgical result was rated as acceptable.
