 note = {Background: The recurrence of lumbar disk herniation (LDH) is a major problem in the treatment of LDH. The purpose of this study was to investigate the risk factors for recurrent LDH. Methods: Between April 2005 and March 2008, 298 patients with LDH, who underwent surgical treatment, were enrolled in this study. The patients were divided into a nonrecurrent group (N group) and a recurrent group (R group). We compared their clinical parameters including age, sex, body mass index, smoking, alcohol, sports activity, occupational lifting, and occupational driving. The relationships between the variables and recurrent LDH were evaluated by univariate analysis and multiple logistic regression analysis. Results: The N group had 266 patients (89.3%) and the R group had 32 patients (10.7%). Univariate analysis showed that current smoking (P<0.001) and occupational lifting (P=0.02) significantly correlated with recurrent LDH. Multivariate analysis showed that current smoking significantly related with recurrent LDH (OR, 3.47; 95% CI, 1.55-7.80; P=0.003). Conclusions: Our study suggests that smoking cessation and restraining from lifting may significantly decrease the incidence of recurrent LDH. © 2013 Wolters Kluwer Health, Inc.
