The Spine Network - Clive Segil, M.D. on Spinal Stenosis

Comments by Los Angeles orthopaedic surgeon Clive Segil, M.D. on a new, minimally invasive procedure to treat a type of spinal stenosis called "foraminal" stenosis. "Foramina" are nerve openings in the lumbar spine.

Lumbar spinal stenosis accounts for 1.5 million office visits per year, and is one of the most common reasons to have spine surgery.

If a patient doesn't respond to conservative treatment, the conventional surgical approach has been an extensive procedure called a "decompressive laminectomy" in which the bone structures at the back of the spine are removed to alleviate pressure on the nerves caused by the stenosis, or narrowing of the spinal nerve openings. However, this approach has the disadvantage of destabilizing the spine.

Dr. Segil explains that a new, minimally invasive procedure uses the iO-Flex™ System in which a very small incision is made and a miniature flexible saw is used by the surgeon, guided with x-ray imagery to perform decompression from the inside-out. The procedure takes about an hour and has a shorter recovery time than conventional surgical decompression procedures.
