Retrospective observational study.
There is no consensus to predict improvement of lower back pain (LBP) in lumbar spinal stenosis after decompression surgery. The aim of this study was to evaluate the improvement of LBP and analyze the preoperative predicting factors for residual LBP.
We retrospectively reviewed 119 patients who underwent lumbar decompression surgery without fusion and had a minimum follow-up of 1 year. LBP was evaluated using the numerical rating scale (NRS), Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) LBP score, and Roland-Morris Disability Questionnaire (RMDQ). All patients were divided into LBP improved group (group I) and LBP residual group (group R) according to the NRS score. Radiographic images were examined preoperatively and at the final follow-up. We evaluated spinopelvic radiological parameters and analyzed the differences between group I and group R.
LBP was significantly improved after decompression surgery (LBP NRS, 5.7 vs 2.6, < .001; JOABPEQ LBP score, 41.3 vs 79.6, < .001; RMDQ, 10.3 vs 3.6, < .001). Of 119 patients, 94 patients were allocated to group I and 25 was allocated to group R. There was significant difference in preoperative thoracolumbar kyphosis between group I and group R.
Most cases of LBP in lumbar spinal stenosis were improved after decompression surgery without fusion. Preoperative thoracolumbar kyphosis predicted residual LBP after decompression surgery.
回顾性观察研究。
对于腰椎管狭窄减压手术后下腰痛(LBP)改善情况的预测尚无共识。本研究旨在评估LBP的改善情况并分析术前残余LBP的预测因素。
我们回顾性分析了119例行非融合腰椎减压手术且至少随访1年的患者。使用数字评分量表(NRS)、日本骨科协会腰痛评估问卷(JOABPEQ)的LBP评分以及罗兰-莫里斯功能障碍问卷(RMDQ)评估LBP。根据NRS评分将所有患者分为LBP改善组(I组)和LBP残留组(R组)。术前及末次随访时检查影像学图像。我们评估了脊柱骨盆放射学参数并分析了I组和R组之间的差异。
减压手术后LBP显著改善(LBP NRS评分,5.7对2.6,P <.001;JOABPEQ LBP评分,41.3对79.6,P <.001;RMDQ评分,10.3对3.6,P <.001)。119例患者中,94例被分配至I组,25例被分配至R组。I组和R组术前胸腰椎后凸存在显著差异。
大多数腰椎管狭窄症的LBP病例在非融合减压手术后得到改善。术前胸腰椎后凸可预测减压手术后的残余LBP。
