97 patients in 3 randomized groups were treated by Microdiscectomy for lumbar disc herniation; Group A was operated at 6 weeks of symptoms, Group B at 3 months and group C at 6 months. These patients were followed for 3 years for the clinical and functional outcomes.
150 patients were enrolled in this study and only 97 patients were finally analyzed for primary outcomes measures of Oswestry disability index and Roland-Morris Questionnaire and secondary outcome measures of Visual analogue scale for back pain and leg pain as well as length of hospital stay and time to return for daily activities. Assessments done at different periods of 2 weeks, 3 months, 6 months, 1year, 2 years and 3 years.
