Decompression of Lumbar Spinal Stenosis and Stabilization with Knodt Rods in the Elderly Patient

Abstract

Abstract We present a series of 25 elderly patients who exhibited signs and symptoms of neurogenic claudication and who were found to have one or two levels of spinal stenosis. At the time of decompressive surgery, excessive movement was found at the stenotic levels, so a simple stabilization procedure was performed using Knodt rods and a facet fusion. The expectation was that spine fixation would decrease the amount of postoperative back pain, which can be a result of continued abnormal mobility. All of the patients have been followed for 2 or more years. This elderly group of individuals tolerated surgery well, and long-term results were good.
