Lumbar Spinal Stenosis in Older Adults.

Lumbar spinal stenosis (LSS) is a frequent cause of low back pain among adults, caused by a narrowing impinging on the spinal cord or nerve roots. Several conditions cause LSS, including disc herniation, spondylolisthesis, tumor, fractures, and other degenerative changes. Back pain is frequently experienced. MRI is the radiologic modality of choice. Radiographic evidence of LSS may not correlate well with symptoms. An increase in utilization of surgery has been noted. However, surgery has no significant benefit over more conservative options. An appropriate risk/benefit discussion between the patient and an interdisciplinary medical team is optimal.
