OBJECTIVE: To determine clinical and radiological factors that predict the successful outcome of @entity5663 ( @entity5663 ) in @entity1 with lumbar @entity3976 ( @entity3976 ). METHODS: We retrospectively reviewed the clinical and radiological features of @entity1 who underwent lumbar @entity5663 from April 2009 to March 2013. Sixty-nine @entity1 with lumbar @entity3976 were studied. Clinical outcome was assessed by the visual analogue scale (VAS) and the @entity717 Index (ODI). Multivariate logistic regression analysis was performed to assess relationship among clinical and radiological factors and the successful outcome of the @entity5663 . RESULTS: The VAS and the ODI decreased significantly at 1 year follow-up (p<0.01). One year after @entity5663 , the reduction of the VAS (  VAS) was significantly greater in the @entity1 with @entity158 for <6 months (p=0.03) and subarticular @entity3976 (p=0.015). The reduction of the ODI (  ODI) was significantly greater in the @entity1 with high intensity zone (p=0.04). Multivariate logistic regression analysis revealed the following 5 factors that were associated with the successful outcome after @entity5663 : @entity158 duration for <6 months (odds ratio [OR]=14.036; p=0.006), positive straight leg raising test (OR=8.425, p=0.014), the extruded @entity3976 (OR=0.106, p=0.04), the sequestrated @entity3976 (OR=0.037, p=0.026), and the subarticular @entity3976 (OR=10.876, p=0.012). CONCLUSION: @entity5663 provided significant improvement of @entity158 and disability of @entity1 . The results of the analysis indicated that the duration of @entity158 <6 months, positive straight leg raising test, the subarticular @entity3976 , and the protruded @entity3976 were predicting factors associated with the successful response of @entity5663 in @entity1 with lumbar @entity3976 .
