Neurogenic claudication is a symptom caused by central lumbar stenosis. Most of the time, the stenosis is at L4-5, L3-4 or L2-3 with a combination of 1 or 2 continuous levels. Most patients present with stenosis at L4-5 or L3-4 & L4-5. Symptoms usually start as generalized low back pain across the lower back made worse with standing, walking and extension. Over time, the patient or family member may notice that the patient is frequently “hunched” or flexed forward a few minutes after they stand from a seated position and begin to walk. As they start walking, the pain worsens while flexion begins to relieve the pain. Pain then begins to travel down the legs, bilaterally, sometimes affecting the anterior (front) leg, posterior (back) leg, or both. Once the patient sits down, symptoms begin to subside. Stenosis is a component of Degenerative Disc Disease and can include a central disc herniation and /or facet hypertrophy. Enlargement or hypertrophy of the facet joint can be very painful adding to the back pain. Compression of the nerves from lumbar stenosis causes leg pain or neurogenic claudication. Once the symptoms start, they usually worsen over time.

A Spondylolisthesis at L5-S1 is called an “Isthmic” Spondylolisthesis and affects approximately 5 to 7% of the population. A Spondylolisthesis at L4-5 is a called a “Degenerative” Spondylolisthesis. Both types can be painful and present with back pain, leg pain or both.

If a patient develops a foot drop or other leg weakness, conservative care will be initiated but if the weakness persists, you may surgeon may need to strongly consider surgical decompression.
