Lumbar spinal stenosis is one of the most common causes of back and leg symptoms in adults over 60 and one of the most undertreated. Patients often live with progressive limitation of walking distance for years — assuming it is simply aging — before being evaluated by a spine specialist. The good news: lumbar stenosis is well-understood, reliably diagnosed, and in most patients responds well to treatment, surgical or otherwise.
WHAT IS LUMBAR STENOSIS?
Lumbar spinal stenosis is a narrowing of the spinal canal in the lower back that compresses the cauda equina — the bundle of nerve roots below the spinal cord. The narrowing results from cumulative degenerative changes: disc bulging reduces the front of the canal; facet joint arthritis reduces the sides; and thickening of the ligamentum flavum reduces the posterior space. The result is a compressed, crowded spinal canal that impairs the blood flow and mechanical function of the nerve roots within it.
NEUROGENIC CLAUDICATION
The hallmark symptom of lumbar stenosis is neurogenic claudication — leg pain, heaviness, cramping, numbness, or weakness that comes on with walking or standing and is relieved by sitting or bending forward. Patients describe being able to walk only a short distance before needing to stop and rest. Cycling is often better tolerated because the flexed position opens the spinal canal. This positional nature distinguishes neurogenic claudication from vascular claudication (from arterial disease), which does not improve with bending forward.
SYMPTOMS
- Leg pain, heaviness, or cramping with walking — the most characteristic symptom
- Relief with sitting, lying down, or bending forward
- Progressive reduction in walking distance over months to years
- Back pain — often less prominent than leg symptoms
- Numbness or weakness in the legs with prolonged standing or walking
- Bladder symptoms (urgency) in severe cases
DIAGNOSIS
MRI is the primary diagnostic study, demonstrating the degree of canal narrowing and the levels involved. CT provides bony detail when needed. Standing X-rays assess alignment and rule out spondylolisthesis. Vascular studies may be needed to exclude peripheral artery disease in patients with atypical presentations.
NON-SURGICAL TREATMENT
- Physical therapy — flexion-based lumbar exercises, core strengthening, aquatic therapy
- Epidural steroid injections — can provide meaningful relief of claudication symptoms; most useful as a bridge or for patients not ready for surgery
- Activity modification — using assistive devices, preferring cycling over walking
WHEN IS SURGERY INDICATED?
- Failure of conservative treatment after 3–6 months
- Significant functional limitation — walking less than one block, inability to perform daily activities
- Progressive neurological deficit — worsening weakness, expanding numbness
- Bladder or bowel dysfunction (rare but requires urgent evaluation)
SURGICAL OPTIONS
- Minimally invasive lumbar decompression — for focal stenosis at 1–2 levels without instability; faster recovery than open surgery
- Open lumbar laminectomy — for multilevel stenosis or when access requirements exceed MIS techniques
- Lumbar fusion with decompression — when spondylolisthesis, instability, or deformity coexists with stenosis; decompression alone may worsen instability in these patients
WHY CHOOSE DR. SARDAR
Dr. Sardar treats the full spectrum of lumbar stenosis, from conservative management and injection-guided care to minimally invasive decompression and complex multilevel reconstruction. He selects the treatment and surgical approach based on each patient’s anatomy, symptoms, and functional goals.
