简要总结
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.
详细描述
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.

结局指标
主要结局
Oswestry disability index
时间窗: Oswestry disability index was measured the functional disability at 2 weeks
Primary outcome measure for functional disability, the higher score is better function
Roland-Morris Questionnaire
时间窗: Roland-Morris Questionnaire was measured the functional disability at 2 weeks
Primary outcome measure for functional disability, the higher score is worse function
次要结局
- Length of hospital stay(Measuring the days of postoperative hospital stay immediately after the surgery)
- Visual analogue scale(Visual analogue scale was measured at 2 weeks)
- Return to daily activities(Measuring the time needed t return to daily activities immediately after the surgery)
