This image-guided procedure treats lumbar spinal stenosis by relieving pressure on the spinal nerves with minimal trauma to the surrounding tissues. During this minimally invasive lumbar decompression (mildĀ®) procedure, part of the laminar bone at the site of stenosis is removed (laminotomy) and the ligamentum flavum that supports the laminar bone is partly eliminated, along with fatty tissue. This procedure is intended to reduce or eliminate pain, weakness, stiffness, cramping or numbness in the leg, buttock and groin region. Talk with your doctor to learn more.
