Spinal Stenosis: Do You Really Need Surgery?

Lumbar spinal stenosis is one of the most common causes of leg pain in patients over 60. The narrowing of the spinal canal compresses the nerves, causing the classic symptom of neurogenic claudication — leg pain, heaviness, and cramping that worsens with walking and standing, and improves when you sit down or bend forward.

Many patients with this diagnosis are told their only option is surgery — typically a lumbar laminectomy (removal of bone to widen the canal) or spinal fusion. But that's not always true, and surgery for spinal stenosis carries real risks, particularly in older patients.

Non-Surgical Options Worth Trying First

Epidural Steroid Injections

Lumbar epidural steroid injections reduce inflammation around the compressed nerves and can provide meaningful symptom relief — particularly during acute flares. While not curative for stenosis, they can dramatically improve walking tolerance and quality of life. Many patients use episodic injections to manage symptoms for years.

Physical Therapy

Lumbar flexion-based physical therapy can improve core strength and teach postures that open the spinal canal. Aquatic therapy is particularly well-tolerated for stenosis patients with significant walking limitations.

The MILD Procedure

The MILD (Minimally Invasive Lumbar Decompression) procedure is one of my preferred options for patients with stenosis caused by thickened ligamentum flavum. Through an incision the size of a baby aspirin — no stitches required — I remove small portions of the thickened ligament that's crowding the spinal canal.

No fusion, no general anesthesia, outpatient procedure. Clinical trials show MILD significantly improves walking tolerance, and it's covered by Medicare.

Vertiflex Superion Spacer

The Vertiflex Superion is a minimally invasive interspinous spacer that maintains a slightly flexed posture at the affected spinal level — the position that relieves stenosis symptoms. Placed through a small tube without open surgery, it provides mechanical decompression without removing bone or fusing the spine.

Spinal Cord Stimulation

For patients with refractory neurogenic claudication who have failed other treatments, spinal cord stimulation can dramatically improve walking distance and reduce pain.

When Surgery IS the Right Choice

Surgery is absolutely appropriate in some situations:

• Progressive neurological deficits (worsening weakness, foot drop)
• Bowel or bladder dysfunction from cauda equina involvement
• Failure of comprehensive non-surgical treatment after 6+ months
• Imaging showing severe canal compromise with correlating clinical findings

But surgery should not be the first recommendation for most patients with neurogenic claudication and preserved neurological function.

My Advice

If you've been told you need surgery for spinal stenosis, seek a pain management consultation before making that decision. In my experience, many patients who have been told surgery is inevitable can achieve excellent symptom control through a combination of interventional treatments — often indefinitely.
