Stenosis Surgery

Lumbar Decompression with Coflex Placement

Motion-Preserving Lumbar Stenosis Treatment in Phoenix, AZ — Decompression Without Fusion

For patients with lumbar spinal stenosis, the classic surgery is decompression (laminectomy or laminotomy). While effective, decompression alone can sometimes leave the spine less stable, leading to fusion. The Coflex® Interlaminar Stabilization® device offers an alternative: after decompression, a small implant is placed between the spinous processes to provide stability without eliminating motion. At Desert Spine and Pain, neurosurgeon Dr. David L. Greenwald, M.D., FAANS, FACS offers Coflex placement for properly selected patients, combining reliable decompression with motion preservation.

How the Coflex Device Works

After the nerves are decompressed, a Coflex U-shaped spacer is placed between the spinous processes — adding gentle stabilization while preserving motion, avoiding a full fusion.

Procedure Overview

This procedure combines a decompression for lumbar stenosis with a Coflex interspinous device — a small U-shaped implant placed between the spinous processes at the treated level. The decompression relieves the crowded nerves; the Coflex adds gentle stability and helps keep the canal open, while preserving motion rather than fusing the segment. For select patients, it sits between a decompression alone and a full fusion.

Am I a Candidate?

Coflex is considered for lumbar stenosis at one or two levels in patients who need decompression plus some stabilization — but not a full fusion — and whose anatomy and alignment are suitable. It isn't for every stenosis patient; a careful evaluation determines whether decompression alone, Coflex, or a fusion best fits your spine.

Benefits & Risks

Risks to understand

Risks include bleeding, infection, device issues, and, uncommonly, nerve injury or the later need for a fusion. Coflex suits specific situations — not every stenosis patient. Dr. Greenwald reviews candidacy and risks in detail.

Expected Outcomes

For well-selected patients, decompression with Coflex relieves stenosis symptoms while preserving motion and avoiding the larger footprint of a fusion. The key is candidacy — which is why a careful evaluation by a surgeon who also performs decompression and fusion matters. We set clear, individualized expectations.

Life Beyond the Pain

The goal of treatment is simple: relieve your pain and help you get back to the activities you love. Recovery and results vary from person to person.

How It's Performed

Under general anesthesia, through a minimally invasive posterior approach, the nerves are decompressed by removing the bone and thickened ligament crowding them. The Coflex U-shaped spacer is then placed between the spinous processes at that level to add gentle stabilization while preserving motion. No pedicle screws or fusion are required.

Recovery & Return to Activity

TimeframeWhat to expect
First weekHome the same day or after a short stay. Short, frequent walks; avoid heavy lifting, bending, and twisting; keep the incision clean and dry.
Weeks 2–6Activity increases steadily; many patients return to light or desk work; physical therapy typically begins to rebuild strength and mobility.
Months 2–3Resume most normal activities; symptoms keep improving as the nerves recover.
Month 6Most patients reach full recovery.

Because it avoids a full fusion, recovery can be quicker than a fusion for suitable patients, with the benefits of a minimally invasive decompression. Your timeline depends on the levels treated and your health.

Lumbar Decompression with Coflex: Frequently Asked Questions

What is a Coflex device?

It's a small U-shaped implant placed between the spinous processes after a decompression. It adds gentle stabilization and helps keep the canal open while preserving motion — without a full fusion.

How is it different from a fusion?

A fusion permanently joins the segment with screws and bone graft; Coflex preserves motion and avoids that larger surgery. For a suitable patient, it's a middle-ground option.

Am I a candidate?

Coflex suits lumbar stenosis at one or two levels in patients who need decompression plus some stabilization and have suitable anatomy. A careful evaluation determines whether it fits you.

Is it minimally invasive?

Yes, through a minimally invasive posterior approach, which supports a quicker recovery than a fusion.

Do I need a referral in Phoenix?

No. You can schedule directly with our Phoenix spine specialists, and we welcome out-of-network patients.
