Weber's 1983 RCT enrolled 280 patients with radiculographically confirmed lumbar disc herniation. 126 patients with uncertain surgical indications were randomized to discectomy versus conservative physiotherapy. Follow-up examinations were performed at one, four, and ten years to determine whether surgery confers durable long-term benefit.
For most patients with lumbar disc herniation and no absolute surgical indication, surgery offers faster relief but not better long-term outcomes — this paper is why spine surgeons frame the surgical conversation around timing of recovery, not ultimate result.
When counseling a patient with sciatica and uncertain operative indications, the data support a supervised trial of conservative care: roughly 60% of patients who would qualify for surgery can achieve equivalent results without an operation.
The clearest signal for early surgery remains an absolute indication: progressive motor deficit, bladder or bowel paresis, intolerable pain, or immobile scoliosis. For everyone else, the decision hinges on how long the patient is willing to tolerate symptoms. Not on which treatment produces a better ten-year spine.
One practical prognostic rule from this data: a patient who has already been off work for three or more months before you see them is at significantly higher risk of a poor outcome regardless of what you do. Identify and address psychosocial barriers early.
