Minimally Invasive Lumbar Decompression

If spinal stenosis makes it hard to stand or walk very far without your legs aching — and you’d rather not face major back surgery — the MILD procedure (minimally invasive lumbar decompression) may be an option worth exploring. Our pain physicians offer it across Long Island and northern New Jersey, with offices in Plainview, New Hyde Park, and Ronkonkoma, NY, and Clifton, Montville, and Plainfield, NJ.

What the MILD procedure treats

Lumbar spinal stenosis is a narrowing of the space around the nerves in your lower back. A common cause is a ligament in the spine — the ligamentum flavum — becoming thickened and crowding those nerves. That pressure is what produces the classic symptoms: pain, heaviness, or cramping in the legs that gets worse when you stand or walk and eases when you sit or lean forward.

As Johns Hopkins Medicine describes, minimally invasive lumbar decompression uses a small incision and specialized tools to remove some of that thickened ligament, widening the space and relieving pressure on the nerves. It treats this specific cause of stenosis — it isn’t a general fix for every kind of back pain.

Are you a candidate?

MILD may be worth discussing when:

• Imaging confirms lumbar spinal stenosis with a thickened ligamentum flavum
• Your main symptom is leg pain or heaviness when standing or walking, relieved by sitting or bending forward
• Conservative care — physical therapy, medication, and often epidural injections — hasn’t given you enough relief
• You’d like to try a less invasive step before considering open surgery

Not everyone with stenosis is a fit — it depends on what’s causing the narrowing. An evaluation and a look at your imaging is the only way to know.

What to expect

MILD is done in-office on an outpatient basis under light sedation and local anesthesia. Using live X-ray guidance, the physician works through a very small opening — no large incision, no implant, and no stitches. It usually takes about an hour, and you go home the same day with a driver.

Most people begin returning to normal activities over the first month, with much of the initial soreness and swelling settling within the first few weeks, as Johns Hopkins Medicine notes. Your physician will give you specific activity guidance and let you know if physical therapy is recommended.

How it compares to other stenosis options

Costs depend on your insurance; our team checks coverage before your procedure.

If you haven’t yet tried injections, an epidural steroid injection is often part of the conservative path before a decompression is considered. We’ll help you understand where you are in that sequence.

Frequently asked questions

How long does it take to recover from the MILD procedure?

Most people return to normal activities over the first month, with much of the early soreness and swelling easing within the first few weeks. Your physician will give you specific guidance.

Is the MILD procedure worth it?

For the right patient — stenosis caused by a thickened ligament, with leg symptoms when walking — it can meaningfully improve the ability to stand and walk farther while avoiding bigger surgery. Whether it fits you depends on your imaging and exam.

Who is not a candidate?

People whose stenosis is caused by something other than a thickened ligamentum flavum may not benefit. An evaluation and imaging review is the only way to know for sure.

How much pain is there afterward?

Some soreness and swelling in the first few weeks is normal and usually settles. Let your physician know if pain isn’t improving or seems to be increasing.

Is it surgery?

It’s a minimally invasive procedure done through a tiny opening, without a large incision, implant, or stitches — much less invasive than traditional open back surgery.

How is it different from an epidural steroid injection?

An epidural injection reduces inflammation around the nerves for a period of time. MILD physically removes some of the thickened tissue causing the narrowing. Injections are often tried first in the conservative path.
