Retrospective analysis on a national longitudinal database (2007-2014).To determine the association between arthrodesis and complication rates, costs, surgical revision, and postoperative opioid prescription.Arthrodesis in patients receiving laminectomy for lumbar spondylolisthesis remains controversial. However, population-level evidence to support the use of arthrodesis remains limited.We identified 73,176 patient records and used coarsened exact matching to create comparable populations of patients who received laminectomy or laminectomy with arthrodesis.
