Background: There are many cases with lumbar disk herniation in which asymptomatic lumbar canal stenosis will be diagnosed radiologically. In current study, we compared the outcomes of treating these patients with either laminectomy or laminotomy. Methods: In this randomized clinical trial, there were 40 patients with lumbar disk herniation and asymptomatic lumbar canal stenosis assigned to 2 groups: laminectomy and fenestration.
