Minimally Invasive Lumbar Decompression
Image-guided minimally invasive lumbar decompression (MILD) describes a novel percutaneous procedure for decompression of the central spinal canal in patients with lumbar spinal stenosis (LSS) Which is characterized by pain that increases when a patient walks or stands, then subsides when sitting or bending forward. In this procedure, a specialized cannula and surgical tools are used under fluoroscopic guidance for bone and tissue sculpting near the spinal canal.
During The Procedure
The patient lies facedown on an x-ray table while numbing medication is injected into the targeted area of the back, and then a tiny incision (about the width of a baby aspirin) is made. Specialized tools are inserted, using fluoroscopic guidance for precision, to remove bits of bone and tissue that are compressing the patient’s spinal canal. Neither general anesthesia nor stitches are needed.
This outpatient procedure takes less than an hour and discomfort should be minimal. IV sedation is available and often utilized. In any event, the patient must be driven home and normal activity suspended for several days.
Most patients experience about a 50 percent reduction in pain and discomfort, and become able to stand and walk for longer distances and longer periods of time.
