[Lumbar disk prolapse. Alcohol, tobacco and prognosis].

The aim of the study was to examine whether smoking or the intake of different alcoholic beverages are associated with the outcome after first time lumbar disc surgery. One hundred and forty-eight patients consecutively operated upon for lumbar disk herniation over a one-year period were classified according to various social and demographic variables. Two and a half years later they were asked about their drinking and smoking habits and the outcome of the operation was assessed using a rating scale. Results showed that intake of wine, but not other alcoholic drinks, was associated with a good prognosis. Logistic regression analysis calculated that intake of wine was associated with a fourfold increase in success rate. This odds ratio was not significantly reduced by the following variables: Age, sex, smoking habits, employment status, social class, household income or marital status. In conclusion, intake of wine was associated with a good prognosis after lumbar discectomy.
