If, when, and how to fuse when treating lumbar degenerative stenosis

The U.S. population is living longer and staying increasingly more active. Symptoms of degenerative lumbar spinal stenosis are being seen with increasing frequency in older age groups. Many of the more symptomatic patients do not respond to nonoperative care and seek potential surgical solutions. The current article offers an evidence-based review of the literature for surgical treatment of degenerative lumbar spinal stenosis with a focus on the role of lumbar fusion. The author evaluates the evidence for surgical treatment of this condition so that appropriate, patient-centered care can be provided in the safest and most cost-effective manner possible.
