Overview
Minimally Invasive Lumbar Decompression (MILD®) Procedure
Lumbar spinal stenosis (LSS) is a common condition in older adults, often caused by the thickening of a spinal ligament called the ligamentum flavum. This can compress the spinal canal and nerves, leading to pain, numbness, and reduced mobility. The MILD® procedure is a safe, image-guided, outpatient treatment that relieves pressure on the spinal cord by removing small portions of this thickened tissue, without the need for open surgery or general anesthesia.
During the MILD procedure, your specialist will make a very small incision in the lower back and use advanced tools to access the spinal canal and remove the excess ligament tissue. The entire procedure is performed under local anesthesia and takes less than an hour. Because the structure of your spine remains intact, the risk of instability is minimal, and recovery is typically quick.
This procedure is FDA-cleared, Medicare-covered, and has been shown in clinical studies to significantly reduce pain and improve walking ability in patients with LSS.
Procedure Overview:
- No Stitches Required: The incision is typically closed with a bandage; no general anesthesia or implants.
- Imaging Guidance: Fluoroscopy (real-time X-ray) is used to locate the stenotic area.
- Small Incision: A tiny incision (~5 mm) is made in the lower back.
- Access to Spine: A portal device is inserted to access the spinal canal.
- Tissue Removal: Specialized instruments are used to remove small portions of the lamina and the thickened ligamentum flavum, decompressing the spinal canal.
Frequently Asked Questions
How long will this procedure take?
The MILD procedure typically takes less than 60 minutes. You’ll be able to return home the same day, and most patients are up and walking shortly after the procedure.
How will I feel afterwards?
Most patients experience mild soreness or discomfort at the incision site for a few days, which can be managed with over-the-counter pain medications. Many report immediate improvement in their ability to stand or walk, with continuing improvement over the following weeks.
How long will the relief last?
Clinical studies have shown that relief from the MILD procedure can last for several years. Patients often experience lasting improvements in mobility and a significant reduction in pain, particularly when the procedure is performed early in the progression of spinal stenosis.
