目的：评价神经根沉降征在腰椎滑脱症（LS）和腰椎间盘突出症（LDH）患者中的表现，并比较其在二者中的差异。方法收集天津市天津医院脊柱外科2012年7月—2014年3月行手术治疗的腰椎退行脊柱病患者资料151例，分为LS组48例和LDH组103例。采用JOA评分评估2组患者术前临床表现，比较2组患者神经根沉降征阳性率，分析JOA评分与神经根沉降征的关系。结果 LS组和LDH患者在JOA评分差异无统计学意义（15.83±3.57 vs 16.76±3.10，t=1.624，P=0.107）。LS组神经根沉降征阳性39例（81.25%），而LDH组65例（63.11%），差异有统计学意义（χ2=5.028，P=0.031）。LS组中，神经根沉降征阳性者JOA评分低于阴性者（15.33±3.50 vs 18.00±3.20，t=2.092，P=0.042）；而LDH组中，神经根沉降征阳性和阴性者JOA评分差异无统计学意义（16.40±3.13 vs 17.37±2.99，t=1.539，P=0.127）。结论神经根沉降征阳性也见于腰椎间盘突出症中，但在临床表现更严重的腰椎滑脱症患者中更易出现。

Objective To evaluate and compare the presence of the nerve root sedimentation sign in patients with lumbar spondylolisthesis (LS) and lumbar disc herniation(LDH). Methods One hundred and fifty-one patients with degen?erative lumbar spinal disease treated by surgery from July 2012 to March 2014 were reviewed retrospectively in Tianjin Hos?pital. All the patients were divided into two groups:LS group (48 cases) and LDH group (103 cases). The clinical outcomes were evaluated by Japanese Orthopedic Association (JOA). The probability of positive sedimentation sign was compared be?tween LS group and LDH group. Correlation between the JOA score and nerve root sedimentation sign were analysed in two groups. Results There was no statistical difference in JOA score between LS group and LDH group (15.83±3.57 vs 16.76± 3.10, t=1.624, P=0.107). A positive sedimentation sign was identified in 39 patients in the LS group (81.25%) but in 65 pa?tients in the LDH group (63.11%). The difference between LS group and LDH group was statistically significant(χ2=5.028, P=0.031). In LS group, JOA scores of patients with positive nerve root sedimentation sign were lower than those of patients with negative nerve root sedimentation sign(15.33±3.50 vs 18.00±3.20, t=2.092,P=0.042);but in LDH group, there was no statistical difference in JOA scores of patients between positive nerve root sedimentation sign and negative nerve root sedi?mentation sign (16.40±3.13 vs 17.37±2.99, t=1.539, P=0.127). Conclusion A positive sedimentation sign also occurs in pa?tients with LDH, but positive nerve root sedimentation sign are more likely to appear in patients with lumbar spondylolisthe?sis who have worse clinical symptoms.
