Lumbar spinal stenosis (LSS) is often a position-dependent condition that is aggravated in extension and relieved in flexion.
Ten consecutive elderly patients with LSS were assessed postoperatively by magnetic resonance imaging and the Swiss Spinal Stenosis Questionnaire. Cross-sectional areas of the dural sac and intervertebral foramina at the stenotic level were measured postoperatively and compared with the preoperative values.
Postoperatively the cross-sectional area of the dural sac increased 16.6 mm2 or 22.3% and intervertebral foramina increased 22 mm2 or 36.5%. The intervertebral angle and the posterior disc height changed significantly. Seventy percent of the patients were satisfied with the surgical outcome.
This new surgical method is effective in elderly LSS patients.
腰椎管狭窄症（LSS）通常是一种与体位相关的疾病，伸展时加重，屈曲时缓解。
连续10例老年LSS患者术后接受磁共振成像和瑞士脊柱狭窄症问卷评估。术后测量狭窄节段硬脊膜囊和椎间孔的横截面积，并与术前值进行比较。
术后硬脊膜囊横截面积增加16.6平方毫米或22.3%，椎间孔增加22平方毫米或36.5%。椎间角度和椎间盘后高度有显著变化。70%的患者对手术结果满意。
这种新的手术方法对老年LSS患者有效。
