The MILD Procedure for Lumbar Spinal Stenosis

Meaningful Mobility Improvements and Back Pain Relief


Excruciating back pain that makes it difficult to walk or stand for long periods of time.

The diagnosis: lumbar spinal stenosis (LSS).

MILD Lumbar Spinal StenosisEach of us has a bundle of nerves that runs through a tunnel in our spine, called the spinal canal. When that spinal canal narrows, it creates pressure on those nerves. This narrowing is called spinal stenosis.

It’s a common condition for because osteoarthritis will begin to change most of our spines starting around the age of 50. Statistically, women have a higher risk of developing this condition than men.

Symptoms? Pain in your back, particularly in the lower back. A burning pain that goes into your buttocks and runs down into your legs. A loss of sensation or weakness in your feet.

Treatments? Physical therapy can help. Medicines and targeted injections can relieve pain and swelling. But if those options aren’t effective, what’s your next step short of major surgery?

LSS sufferers in this situation may be candidates for an ultra-minimally invasive procedure called MILD®.

The MILD® Procedure

MILD is a treatment option to consider when conservative therapies such as physical therapy, medicines and injections fail to provide adequate relief. This procedure focuses on a major root cause of lumbar spinal stenosis by removing excess ligament tissue to restore space in the spinal canal.

The MILD® procedure typically takes less than an hour and is performed with local anesthetic and light sedation. It involves a single, tiny incision that is smaller than the size of a baby aspirin (5.1mm).

Clinical Outcomes

MILD® has been performed on thousands of patients to provide lasting pain relief and increased mobility. Clinical outcomes for MILD® include:

  • Increased Standing Time: Cleveland Clinic 1-Year Study: Patients were able to increase average standing time from 8 minutes to 56 minutes with less pain.
  • Increased Walking Distance: Cleveland Clinic 1-Year Study: Patients were able to increase their average walking distance from 246 feet to 3,956 feet with less pain.
  • Avoiding Back Surgery: Cleveland Clinic 5-Year Study: MILD® helped 88% of patients avoid back surgery for at least 5 years while providing lasting relief.
  • Safety Profile Similar to an Epidural Steroid Injection: MIDAS ENCORE 2-Year Study: MILD® has a safety profile similar to an epidural steroid injection, but with lasting results. In this study, there were no statistically significant differences in the safety profile between study groups.
  • Patient Satisfaction: MIDAS ENCORE 2-Year Study: Patients reported an 85% patient satisfaction rate with the MILD® procedure.

After the MILD® procedure, patients are able to return home the same day and resume light tasks and everyday activities within just a few days. Your Main Line Spine medical team will provide complete instructions on what to do immediately following the procedure and will schedule any necessary follow-up visits or suggested rehabilitation.
