Scientific title	Controlled trial of microdiscectomy for lumbar disc herniation
Study hypothesis	The UK has one of the lowest rates for lumbar disc surgery in the western world. A robust randomised controlled trial, incorporating a health economic analysis, is needed, considering the lack of evidence about clinical outcome and cost effectiveness, particularly in the medium and long term. Microdiscectomy, the standard surgical procedure, will be compared to conservative management. The study will be based in two neurosurgical departments, both leading centres for disc surgery. Follow-up will be at 3, 6, 12, 18 and 24 months, incorporating outcome measures of proven reliability and validity. The objectives of this project at to: 1. establish the efficacy and cost-effectiveness of surgical management for this patient group 2. to evaluate costs to health care purchasers of surgical and conservative management. A supplementary study will undertake follow-up at 3, 4, and 5 years, although funding is not being applied for at this stage.
