Spinal Stenosis Treatment in Napa, CA

What Is Spinal Stenosis?

Spinal stenosis is a condition in which the spaces within the spinal canal gradually narrow, placing pressure on the spinal cord and surrounding nerves. The spinal canal is the bony tunnel that runs through the center of your spine, protecting the delicate nerve pathways that connect your brain to the rest of your body. When that space tightens, the compressed nerves can produce pain, numbness, and weakness that progressively limit your ability to walk, stand, and stay active.

Lumbar spinal stenosis, which affects the lower back, is the most common form and the primary cause of neurogenic claudication in older adults. According to a systematic review published in the European Spine Journal, approximately 11% of the general adult population has clinical evidence of the condition, and it is among the most common reasons older adults seek spine-related care. The condition affects over 103 million people worldwide.

Spinal stenosis develops gradually, most often as a result of age-related degenerative changes. One of the most significant contributors is hypertrophy (thickening) of the ligamentum flavum, a band of tissue that lines the back of the spinal canal. As this tissue thickens over time, it encroaches on the space available for your spinal nerves. Research published in the Journal of Bone and Joint Surgery found that the ligamentum flavum in patients with spinal stenosis was more than twice as thick as in patients without the condition (5.7mm versus 2.7mm). This thickening is a key factor that Dr. Weisbein evaluates when determining whether a patient may be a candidate for the MILD procedure.

Cervical spinal stenosis, which affects the neck, can also occur but is less common. For most patients, lumbar stenosis is where daily life is affected most and where the most significant treatment advances have emerged.

Symptoms of Spinal Stenosis

Spinal stenosis often develops slowly. You may not notice symptoms for months or years as the spinal canal gradually narrows. When symptoms do appear, they tend to follow a recognizable pattern that worsens over time without treatment.

Neurogenic Claudication: The Hallmark Symptom

The most characteristic symptom of lumbar spinal stenosis is neurogenic claudication, pain, heaviness, or cramping in the legs that worsens with walking or prolonged standing and improves when you sit down or lean forward. Many patients describe it as a tired, heavy feeling in both legs that sets in after walking a certain distance. You may notice that leaning on a shopping cart or bending forward at the waist provides relief. This happens because flexing your spine temporarily opens the narrowed canal, reducing pressure on the compressed nerves.

Neurogenic claudication is different from leg pain caused by poor circulation (vascular claudication). The distinction matters because it points directly to a spinal source and helps Dr. Weisbein determine the most effective treatment approach.

Other Common Symptoms

In addition to neurogenic claudication, lumbar spinal stenosis may cause:

•   Pain in the lower back, buttocks, or legs that worsens when standing or walking

•   Numbness or tingling (“pins and needles”) in the legs or feet

•   Weakness in one or both legs

•   Difficulty with balance or coordination

•   A noticeable decrease in how far you can walk before needing to stop and rest

•   Symptoms that improve when sitting, lying down, or leaning forward

When to Seek an Evaluation

If leg pain or numbness limits how far you can walk, if you find yourself avoiding activities you once enjoyed, or if your symptoms have not improved with rest and over-the-counter medications, it may be time to see a specialist. Dr. Weisbein provides comprehensive evaluations to determine whether your symptoms are caused by spinal stenosis and, if so, what treatment approach may offer the most relief.

Spinal stenosis is one of several conditions that can contribute to persistent low back pain. A thorough evaluation is the first step toward understanding what is driving your symptoms.

What Causes Spinal Stenosis?

Spinal stenosis is most often the result of age-related wear and tear on the spine. As the body ages, the structures that support and protect the spinal canal can change in ways that gradually reduce the available space for nerves. Understanding what drives this narrowing helps guide treatment decisions.

The most common causes include:

•   Ligamentum flavum hypertrophy. The ligamentum flavum is a flexible band of tissue that lines the back of the spinal canal. Over time, this tissue can thicken and stiffen, pushing into the canal and compressing the nerves within it. Ligamentum flavum hypertrophy is one of the most significant contributors to lumbar spinal stenosis and is the specific structural problem that the MILD procedure is designed to address.

•   Bone spurs (osteophytes). Osteoarthritis can cause new bone growth along the edges of the vertebrae. These bony projections can extend into the spinal canal and narrow the space available for nerves.

•   Bulging or herniated discs. The cushioning discs between your vertebrae can flatten, bulge, or rupture with age, pressing against the spinal canal or nerve roots.

•   Facet joint enlargement. The small joints that connect each vertebra can become enlarged due to arthritis, contributing to canal narrowing.

•   Spondylolisthesis. When one vertebra slips forward over the one below it, the misalignment can narrow the spinal canal and compress nerves.

•   Previous spinal injury. Fractures, dislocations, or inflammation from a prior injury can lead to structural changes that contribute to stenosis over time.

In many patients, more than one of these factors is present at the same time. Dr. Weisbein’s evaluation identifies which specific structures are contributing to the narrowing so that treatment can be directed at the actual source of your symptoms.

How Is Spinal Stenosis Diagnosed?

Diagnosing spinal stenosis requires more than confirming that the spinal canal has narrowed. Dr. Weisbein’s evaluation is designed to identify exactly which structures are causing the compression, how severely the nerves are affected, and which treatment approach is most likely to help.

Comprehensive Physical Examination

Dr. Weisbein begins with a detailed review of your medical history, including when your symptoms started, what makes them better or worse, and what treatments you have already tried. She then performs a physical examination that includes gait assessment, neurological testing for reflexes and sensation in the legs, and range-of-motion evaluation. She may ask you to walk a short distance to observe whether your symptoms reproduce with activity, a direct way to assess neurogenic claudication in real time.

Diagnostic Imaging

Imaging studies are essential for confirming the diagnosis and planning treatment. Dr. Weisbein may order:

•   MRI (magnetic resonance imaging). The primary imaging tool for spinal stenosis. An MRI provides detailed images of soft tissues, including the ligamentum flavum, discs, and nerve roots, allowing Dr. Weisbein to measure the degree of canal narrowing and evaluate whether ligamentum flavum hypertrophy is a contributing factor.

•   X-rays. Useful for identifying bone spurs, spondylolisthesis, and other structural changes in the vertebrae.

•   CT scan. May be recommended when MRI is not an option or when a more detailed view of bony structures is needed.

The imaging findings, combined with your symptom pattern and physical exam results, allow Dr. Weisbein to determine the underlying cause of your stenosis and whether you may benefit from conservative care, epidural injections, or a minimally invasive procedure like the MILD procedure.

Spinal Stenosis Treatment Options

Spinal stenosis treatment is not one-size-fits-all. The right approach depends on the severity of your symptoms, how long you have been experiencing them, and what is causing the narrowing. Dr. Weisbein develops individualized treatment plans that may combine multiple approaches to address your specific condition.

Conservative Care

For patients with mild to moderate symptoms, conservative measures are typically the starting point. These may include:

•   Physical therapy. Targeted exercises to strengthen the muscles that support your spine, improve flexibility, and reduce pressure on compressed nerves. A physical therapist can also help you learn movement patterns that minimize symptom flare-ups.

•   Activity modification. Adjustments to daily activities that reduce prolonged standing and walking while keeping you as active as possible.

•   Medication management. Over-the-counter anti-inflammatory medications (NSAIDs) can help manage pain and inflammation. In some cases, Dr. Weisbein may recommend prescription options for short-term relief.

Epidural Steroid Injections

When conservative measures alone are not providing adequate relief, epidural steroid injections may help reduce inflammation around the compressed nerves. These image-guided injections deliver anti-inflammatory medication directly to the affected area of the spine.

Evidence from a 2025 systematic review published in Neurology suggests that epidural steroid injections may reduce short-term disability in patients with lumbar spinal stenosis, though the benefits are often temporary. For many patients, injections provide meaningful relief while allowing time to evaluate whether additional intervention may offer more durable improvement.

When Conservative Treatment Is Not Enough

If your symptoms persist or worsen despite physical therapy, medication, and injections, you may be a candidate for a minimally invasive procedure that targets the structural source of your stenosis. For patients whose imaging confirms ligamentum flavum hypertrophy as a contributing factor, the MILD procedure may offer a durable, outpatient alternative to open surgery.

The MILD Procedure: Minimally Invasive Lumbar Decompression

For patients with lumbar spinal stenosis caused by a thickened ligamentum flavum, the MILD procedure offers a well-established, evidence-backed treatment option that can restore space in the spinal canal without open surgery, general anesthesia, or implants.

MILD stands for minimally invasive lumbar decompression. During the procedure, Dr. Weisbein uses specialized instruments and real-time imaging guidance to remove small portions of excess bone and thickened ligamentum flavum tissue through a single, small incision. By restoring space in the spinal canal, the procedure reduces pressure on the compressed nerves that cause neurogenic claudication, leg pain, and limited walking ability.

What Makes MILD Different from Surgery

Many patients with spinal stenosis are told that open spinal surgery (typically a laminectomy) is their only option. The MILD procedure is not surgery. Key differences include:

•   No general anesthesia. MILD is performed using local anesthesia and light sedation. You remain comfortable but avoid the risks associated with general anesthesia.

•   No implants. Unlike spinal fusion or interspinous spacers, the MILD procedure does not leave any permanent hardware in your spine.

•   No hospitalization. MILD is an outpatient procedure, typically completed in under an hour. Most patients go home the same day.

•   Minimal recovery time. Many patients return to light daily activities within days, with a gradual return to full activity as directed by Dr. Weisbein.

For patients who do not respond to minimally invasive options, surgical decompression may be considered. Dr. Weisbein’s approach prioritizes the least invasive path first. For patients with chronic pain that persists after treatment, advanced options such as spinal cord stimulation may also be appropriate.

What the Evidence Shows

Dr. Weisbein is not only a fellowship-trained interventional pain specialist who has performed thousands of procedures over a decade and a half, she is also a published author on MILD procedure research. A comprehensive review she co-authored in Pain Management evaluated the procedure’s indications, safety, and efficacy, concluding that MILD demonstrated a safety profile equivalent to epidural steroid injections with superior efficacy. The review recommended MILD as the first intervention after failure of conservative measures for lumbar spinal stenosis patients with neurogenic claudication and ligamentum flavum hypertrophy.

Additional published evidence supports the durability and effectiveness of the procedure:

•   A Cleveland Clinic study published in Pain Practice followed patients for five years after MILD and found that only 12% required surgical decompression during that period. Patients experienced significant pain relief and reduced opioid use at three, six, and twelve months following the procedure.

•   Research published in Medical Devices demonstrated that MILD produced significant symptom improvement in both younger adults and patients over 65, with no meaningful difference in outcomes between age groups.

•   A study published in Pain Management found that patients who received multiple epidural steroid injections before MILD showed no additional benefit compared to those who underwent MILD earlier in their treatment course, supporting earlier intervention when imaging confirms ligamentum flavum hypertrophy.

Are You a Candidate for the MILD Procedure?

MILD may be appropriate for patients who:

•   Have been diagnosed with lumbar spinal stenosis

•   Experience neurogenic claudication (leg pain, heaviness, or cramping that worsens with walking and improves with sitting or leaning forward)

•   Have imaging (MRI) that confirms ligamentum flavum hypertrophy as a contributing factor

•   Have not experienced lasting relief from conservative care or epidural injections

Candidacy for the MILD procedure requires a formal consultation and imaging review with Dr. Weisbein. The procedure is not appropriate for every stenosis patient, and a thorough evaluation is essential to determine whether MILD is likely to provide meaningful improvement for your specific condition.

Living with Spinal Stenosis in Napa Valley

A spinal stenosis diagnosis does not mean giving up the activities that make life in Napa Valley worth living. With the right treatment plan, many patients are able to return to hiking vineyard trails, cycling through wine country, golfing, gardening, and spending active time with family and friends.

Ongoing management plays an important role in maintaining your results after treatment. Dr. Weisbein works with each patient to develop a long-term plan that may include regular exercise, core strengthening, and periodic follow-up to monitor your progress. Staying active within your comfort level is one of the most effective ways to support spinal health and manage symptoms over time.

Spinal stenosis can also occur alongside other conditions that contribute to pain and limited mobility. Sacroiliac joint dysfunction and chronic back pain are common in patients with degenerative spinal changes, and Dr. Weisbein evaluates for these during your initial assessment so that all contributing factors can be addressed together.

If you are living with spinal stenosis and have not found lasting relief, a comprehensive evaluation is the first step toward understanding your options.
