腰椎间盘突出症术后并发下腰痛的危险因素分析

Analysis of the risk factors for low back pain after the operation of lumbar disc herniation

目的:探索腰椎间盘突出症术后下腰痛发生率及危险因素。方法:回顾性分析自2009年1月至2011年12月在我院行腰椎间盘单纯后路开窗髓核摘除手术的103例患者,采用单因素和多因素结合的方法筛选影响因素。结果:腰椎间盘突出症术后下腰痛发生率为20.4%。年龄越大(OR=1.51,95%CI:1.17～1.83),BMI指数越高(OR=2.17,95%CI:1.92～2.47),吸烟(OR=1.72,95%CI:1.55～2.04),合并心血管疾病(OR=2.78,95%CI:2.13～4.32)等因素可明显增大下腰痛的发生率。结论:年龄大、肥胖、吸烟和合并心血管疾病等可增大椎间盘突出症术后下腰痛的发生风险。

Objective：To investigate the risk factors for low back pain after the operation of lumbar disc herniation. Methods： Infor- mation of medical record and demographic characteristics from 103 patients who were hospitalized for lumbar disc herniation surgery during Jan. 2009 to Feb. 2011 in our hospital were retrospectively collected. Risk factors were screened using univariate and multivari- ate analysis. Results： The grand rate of low back pain is 30.1%. Factors including age （ OR = 1.51,95% CI： 1.17 ~ 1.83 ） , BMI （ OR = 2.17, 95 % CI ： 1.92 ~ 2.47 ） , smoking statue （ OR = 1.72, 95 % CI ： l. 55 - 2.04） and cardiovascular disease related compli- cations significantly increased the occurrence of low back pain. Conclusion： Patients who were at old age, in higher BMI, smoking and combined with cardiovascular diseases had a higher risk of low back pain after the operation of lumbar disc herniation.
