Decompression surgery is the most common surgical treatment for lumbar spinal stenosis (LSS). Relatively low satisfaction rate was reported. Patients often complaint of residual numbness despite significant pain relief. We hypothesized that numbness had a significant impact on patient satisfaction, but had not been evaluated, which is associated with low satisfaction rate. This study aimed to examine how much numbness is associated with patient satisfaction. We retrospectively reviewed prospectively collected data from consecutive patients who underwent decompression without fusion for LSS. We evaluated the Numeric Rating Scale (NRS) scores of low back pain (LBP), leg pain, and leg numbness preoperatively and at the final follow-up visit. Improvement was evaluated using minimum clinically important differences (MCIDs). Patient satisfaction was evaluated using the question, "How satisfied are you with the overall result of your back operation?". There are four possible answers consisting of "very satisfied (4-point)", "somewhat satisfied (3-point)", "somewhat dissatisfied (2-point)", or "very dissatisfied (1-point)". Spearman correlation was used to evaluate the association between patient satisfaction and reaching MCIDs. A total of 116 patients were included. All three components had correlation with patient satisfaction with the correlation efficient of 0.30 in LBP, 0.22 in leg pain, and 0.33 in numbness. Numbness had greatest correlation efficient value. We showed that numbness has a greater impact than leg/back pain on patient satisfaction in patients undergoing decompression for LSS. We suggest not only LBP and leg pain but also numbness should be evaluated pre- and postoperatively.
减压手术是治疗腰椎管狭窄症（LSS）最常见的手术治疗方法。报告的满意度相对较低。尽管疼痛明显缓解，但患者常抱怨仍有麻木感。我们假设麻木感对患者满意度有重大影响，但尚未进行评估，这与低满意度有关。本研究旨在探讨麻木感与患者满意度的关系。我们回顾性分析了连续接受减压而未融合治疗 LSS 的患者前瞻性收集的数据。我们评估了术前和最后随访时的下腰痛（LBP）、腿痛和腿部麻木的数字评分量表（NRS）评分。使用最小临床重要差异（MCID）评估改善情况。使用以下问题评估患者满意度：“您对背部手术的总体结果有多满意？”。有四个可能的答案，分别是“非常满意（4 分）”、“有点满意（3 分）”、“有点不满意（2 分）”或“非常不满意（1 分）”。Spearman 相关分析用于评估患者满意度与达到 MCID 之间的关系。共纳入 116 例患者。所有三个组成部分均与患者对 LBP 的满意度相关，相关效率为 0.30，对腿痛的相关效率为 0.22，对麻木的相关效率为 0.33。麻木具有最大的相关效率值。我们表明，在接受减压治疗 LSS 的患者中，麻木对患者满意度的影响大于腿部/背部疼痛。我们建议不仅要评估术前和术后的 LBP 和腿痛，还要评估麻木感。
