Lumbar Spinal Stenosis

Lumbar spinal stenosis (LSS) is a common, painful spine condition. It generally occurs in older patients who have degenerative changes in the lumbar spine. A careful history will aid in the appropriate diagnosis of LSS, although the physical examination findings may be nonspecific. While exact diagnostic criteria for LSS have not been agreed upon, radiologic and electrodiagnostic studies can help confirm the diagnosis. Treatment generally progresses from conservative to aggressive. High-quality evidence regarding definitive treatment options is lacking, so therapeutic options should be discussed on a case-by-case basis.
