MILD Procedure
What it is
The MILD procedure is for spinal stenosis in the low back. Through a very small opening, the doctor removes a bit of thick tissue that crowds the nerves. This may make it easier to stand and walk.
Why it is done
- Lumbar spinal stenosis with a thickened ligamentum flavum on MRI or CT
- Leg pain or heaviness with standing or walking that eases with sitting
- Symptoms not adequately improved with conservative care
What to expect
- Before: We review your imaging to make sure this procedure fits your type of stenosis.
- During: You get numbing medicine and light sedation. The doctor works through a very small opening in the back. It usually takes less than an hour.
- After: Most people go home the same day with a small bandage. Walking is encouraged.
Self-care tips
- Rest the day of your injection. Most people return to light activity the next day.
- Ice on the site for 15 to 20 minutes may ease soreness.
- Keep a pain diary for 2 weeks to share with us.
- Keep taking your usual medicines unless we tell you otherwise.
When to call us
- Fever or chills
- Redness, swelling, warmth or drainage where the needle went in
- Pain that is much worse than before, or new weakness or numbness
- A bad headache that is worse when you sit or stand
Call 911 for trouble breathing, chest pain, or loss of bladder or bowel control.
