What is spinal stenosis?

Spinal stenosis is a narrowing of the spinal canal that puts pressure on the spinal cord and nerves. This can cause pain, numbness, and weakness, particularly in the legs when walking.

What causes spinal stenosis?

Spinal stenosis is most commonly caused by age-related changes including arthritis, thickened ligaments, bone spurs, and herniated discs that narrow the spinal canal. Some people may also be born with a naturally narrow spinal canal.

How is spinal stenosis treated?

Treatment begins with conservative options like physical therapy, medications, and epidural injections. When these fail to provide adequate relief, minimally invasive surgical options like laminectomy can provide effective decompression of compressed nerves.

When does spinal stenosis need surgery?

Spinal stenosis typically needs surgery when walking distance drops below one to two blocks despite 3–6 months of dedicated conservative treatment, when leg weakness or numbness is progressive and affecting balance or safety, or when bowel or bladder dysfunction develops. Surgery involves decompression — creating more space for the compressed nerves — most commonly through a laminectomy, and in select cases through an endoscopic approach. Most decompression procedures allow same-day or next-day discharge.

What does spinal stenosis feel like?

Spinal stenosis typically feels like heaviness, cramping, aching, or burning in the legs that comes on with walking or standing and eases when you sit down or lean forward. This is called neurogenic claudication — the hallmark symptom of lumbar spinal stenosis. Some people describe it as their legs feeling like concrete or giving out after walking a short distance. Numbness and tingling in the legs or feet are also common.

Can spinal stenosis be treated without fusion?

Yes — the large majority of spinal stenosis cases are treated with decompression alone, without fusion. A laminectomy or endoscopic decompression creates more room for the compressed nerves without joining bones together. Fusion is reserved for cases where decompressing the stenosis would destabilize the spine, such as when there is also spondylolisthesis or scoliosis. Most patients do not need a fusion.

When should I see a surgeon for spinal stenosis?

You should see a spine surgeon for spinal stenosis when walking distance has dropped below one to two blocks despite 3–6 months of conservative treatment, when leg weakness or numbness is getting noticeably worse, when you have had falls because your legs gave out, or when you develop bowel or bladder changes — which require urgent evaluation.

Spinal Stenosis Treatment in Fort Wayne, IN

Spinal stenosis is narrowing of the spinal canal that crowds the nerves, most often in the low back or neck. In the low back it typically causes leg pain, heaviness, or cramping with walking that eases when you sit or lean forward. Treatment ranges from therapy and injections to targeted decompression.

Symptoms

Neurogenic Claudication

Leg pain, cramping, or weakness that occurs when walking and improves with sitting or leaning forward.

Numbness and Tingling

Loss of sensation or pins-and-needles feeling in the legs, feet, arms, or hands depending on the location.

Balance Problems

Difficulty maintaining balance while walking, especially in cervical stenosis cases.

Muscle Weakness

Progressive weakness in the legs or arms that may affect your ability to perform daily activities.

Causes

Arthritis

Osteoarthritis can cause bone spurs and thickened ligaments that narrow the spinal canal.

Natural aging process causes ligaments to thicken and discs to bulge.

Herniated Discs

Bulging or herniated discs can contribute to spinal canal narrowing.

Congenital Factors

Some people are born with a naturally narrow spinal canal.

Diagnosis

Clinical Evaluation

Dr. Greenberg will assess your walking ability, perform neurological tests, and evaluate your symptoms to identify characteristic patterns of spinal stenosis.

Neurological examination
Symptom pattern analysis

Advanced Imaging

MRI and CT scans provide detailed images of the spinal canal, showing the degree of narrowing and identifying specific structures causing compression.

MRI for soft tissue detail
CT for bone structure
Myelography when needed

Functional Assessment

Evaluation of how stenosis affects your daily activities and quality of life helps guide treatment decisions and measure improvement.

Conservative Treatment

Initial treatment for spinal stenosis focuses on non-surgical approaches to reduce symptoms and improve function. Many patients experience significant relief with conservative care.

Physical Therapy

Exercises to strengthen core muscles, improve flexibility, and enhance walking tolerance.

Epidural Injections

Targeted steroid injections to reduce inflammation and provide pain relief.

Medications

Anti-inflammatory drugs, nerve pain medications, and muscle relaxants as appropriate.

Assistive Devices

Walking aids or braces to improve stability and reduce symptoms during activity.

Activity Modification

Adjusting daily activities and using proper body mechanics to minimize symptoms.

Manual Therapy

Chiropractic care and massage therapy to improve mobility and reduce muscle tension.

When stenosis needs surgery

Spinal stenosis typically needs surgery when walking distance drops below one to two blocks despite 3–6 months of dedicated conservative treatment, when leg weakness or numbness is progressive and affecting balance or safety, or when bowel or bladder dysfunction develops — an indication for urgent surgical evaluation and decompression of the compressed nerves. If you are weighing whether your stenosis has reached the surgical threshold, an honest second-opinion consultation can help clarify the decision.

Red flags that point toward surgery

Spinal stenosis tends to progress gradually, and many people manage well without surgery. However, several findings shift the balance toward surgical decompression. The most important red flag is progressive walking limitation — when your walking distance shrinks from several blocks to half a block or less, and leaning on a shopping cart no longer provides enough relief, the stenosis has advanced beyond what conservative care can typically address. New or worsening leg weakness, particularly foot drop or difficulty rising from a chair, signals ongoing nerve compression that may become permanent if not relieved. Bowel or bladder changes — incontinence or retention — represent the most urgent warning sign and require immediate surgical evaluation. Falls caused by leg weakness or balance loss are another serious indicator, as they can lead to additional injuries in patients who already have limited mobility.

When conservative care has been given a fair trial

Conservative treatment for spinal stenosis is typically tried for at least 3–6 months before surgery is considered, unless neurological deficits are rapidly progressing. A fair trial includes structured physical therapy focused on flexion-based exercises and core strengthening, which opens the spinal canal and improves walking tolerance. Epidural steroid injections — often a series of one to three — can reduce inflammation around compressed nerves and provide windows of relief during which therapy is more effective. Activity modification is essential: using a walker or cane, taking sitting breaks during walks, and avoiding prolonged standing or walking downhill. Medications such as gabapentin or pregabalin may help with neurogenic leg pain. If you have done these things and still cannot walk far enough to grocery shop, attend appointments, or enjoy daily life, surgical decompression becomes a reasonable next step.

What spinal stenosis surgery involves

The goal of surgery is to create more space for the compressed nerves — this is called decompression. The most common procedure is a lumbar laminectomy, where a portion of the lamina (the bony roof of the spinal canal) is removed to relieve pressure on the spinal cord and nerve roots. In select cases, an endoscopic approach may be used to perform the decompression through an even smaller opening, potentially reducing muscle disruption and recovery time. If the spine is unstable or if decompression would compromise stability, a fusion may be added — but this is not automatically necessary with every decompression. For cases where fusion is indicated, a TLIF or PLIF procedure may be performed. Most decompression procedures are done in a hospital or surgery center setting, with many patients going home the same day or after an overnight stay. Walking is encouraged immediately, and leg symptoms often improve right away. Desk work can typically resume in 2–4 weeks, with full activity returning gradually over 6–12 weeks depending on the extent of surgery and your pre-operative condition.

Surgical options for spinal stenosis in Fort Wayne

At Greenberg Spine, Dr. Greenberg offers two primary decompression approaches for spinal stenosis that has not responded to conservative treatment. The choice depends on the number of levels involved, the degree of narrowing, whether there is any associated instability, and your overall health and goals. Importantly, most spinal stenosis surgery is decompression only — fusion is reserved for cases where decompression alone would compromise spinal stability. For more on the distinction, see our decompression vs. fusion overview.

Lumbar Laminectomy

The standard decompression procedure — removal of the lamina to create more room for the compressed nerves. Proven effective for central and lateral recess stenosis at one or more levels.

Endoscopic Lumbar Decompression

A minimally invasive camera-guided approach for select stenosis patterns. May reduce muscle trauma and accelerate early recovery compared to open laminectomy.

Not all stenosis patterns are suitable for every technique. During your consultation, Dr. Greenberg will review your MRI or CT, assess your walking tolerance and neurological function, and recommend the decompression strategy most likely to restore your mobility while preserving spinal stability.

When to Consider Surgery

Surgery may be recommended when conservative treatments have not provided adequate relief and symptoms significantly impact your quality of life or when there are progressive neurological deficits.
