Patients with degenerative grade I spondylolisthesis with lumbar spinal stenosis may experience improved quality of life after undergoing a laminectomy with lumbar spinal fusion vs. laminectomy alone, according to findings presented at the American Association of Neurological Surgeons Annual Meeting. According to the release, the researchers concluded that lumbar spinal fusion in addition to laminectomy for the treatment of degenerative grade I spondylolisthesis was associated with superior SF-36 PCS outcome, resulting in fewer reoperations within 4 years of the procedure.
