Evidence comparing the effectiveness of surgical and conservative treatment of symptomatic lumbar disc herniation.
Surgical treatment patients reported less back pain at 6 weeks than those receiving conservative therapy were more likely to report ≥50% decrease in back pain and reported less physical function disability at 52 weeks.The other assessments showed minimal between-groups.
Compared with conservative therapy, surgical treatment provided faster relief from back pain symptoms in patients with lumbar disc herniation, but did not show a benefit over conservative treatment in midterm and long-term outcomes.
