Abstract

To identify predictors of both intermediate and long-term unfavorable outcomes after first time, uncomplicated lumbar disc surgery. Patients (n=120) who had undergone lumbar disc surgery were followed up 1.5 and 12years thereafter. Baseline assessments were carried out 5-8days after surgery. Clinical outcome was assessed in both follow-ups using the Low Back Pain Rating Scale. Statistical analysis included binary logistic and linear regression. Unfavorable outcomes were found in 50.5% (1.5years) and 52.6% (12years) of patients available for follow-up examination.
