Surgery for Lumbar Spinal Stenosis: Attempted Meta-Analysis of the LiteratureTURNER, JUDITH A., PhD*; ERSEK, MARY, MN, RN†; HERRON, LARRY, MD†; DEYO, RICHARD, MD, MPH§Spine: January 1992 - Volume 17 - Issue 1 - p 1–8 Original Article: PDF Only Buy Abstract Author InformationAuthors A meta-analysis was undertaken to determine the effects of surgery for lumbar spinal stenosis on pain and disability. Seventy-four journal articles met inclusion criteria and were independently reviewed by two readers. On average, 64% of patients treated surgically for lumbar spinal stenosis were reported to have good-to-excellent outcomes. However, there was wide variation across studies in the percentage with good outcomes. Few patient characteristics were found to predict outcome. Major deficits in study design, analysis, and reporting were common, and these precluded firm conclusions. *Departments of Psychiatry and Behavioral Sciences and Rehabilitation Medicine, University of Washington, Seattle, Washington, the † Back Pain Outcome Assessment Team, University of Washington, Seattle, Washington, the †Central Coast Spine Institute, San Luis Obispo, California, and the §Departments of Medicine and Health Services, University of Washington and Veterans Affairs Medical Center, Seattle, Washington. © Lippincott-Raven Publishers.
