Minimally Invasive Lumbar Decompression (MILD): Techniques & Outcomes
Caught between conservative care and a large spine surgery, the MILD procedure offers potential as the in-between. On this episode of the BackTable MSK Podcast, Interventional Radiologist Dr. Dana Dunleavy welcomes pain specialist Dr. Denis Patterson to explore the evidence, technique, and evolving role of Minimally Invasive Lumbar Decompression (MILD) procedure for lumbar spinal stenosis with neurogenic claudication.

More about this episode
Dr. Patterson explains the pathophysiology and diagnostic process, highlighting key insights from patient history and MRI findings. The physicians review technique evolution from multiple paramedian incisions and epidurograms to streamlined single midline incision access, and cross lateral oblique (CLO) fluoroscopic safety landmarks.
The discussion also references the MiDAS and Cleveland Clinic studies showing pain and functional improvement with a complication rate similar to epidural steroid injections, along with promising long-term outcomes and reduced need for surgical re-intervention. This episode also tackles practical considerations, including the impact of Category I CPT codes on reimbursement, challenges in radiology reporting, privileging politics, and pathways for physician training and proctoring.
