Lumbar Spinal Stenosis
Lumbar Spinal Stenosis affects over 3 million aging Americans each year.1
Symptoms include lower back pain or shooting pain, weakness, numbness or tingling in your buttocks or legs. Lumbar stenosis is a degenerative condition, which means if left untreated it will worsen over time. Patients begin to have difficulty with many activities and hobbies they enjoy, like bike riding, gardening, golfing or simply walking their dog. It typically affects men and women starting in their 50s and 60s, and the condition is the number one reason for spine surgery in patients over age 65. 2,3
Lumbar stenosis is caused by an overgrowth of bone and tissue in three distinct areas of the vertebra (spinal bone) that press on nerves as they exit the spine and travel to the lower half of the body. There are three distinct areas where lumbar stenosis can occur depending on the location of the overgrown bone and tissue. Research shows most commonly occurs in more than one location.7

About Decompression Surgery
This year alone, an estimated 325,000 surgical procedures that involve decompression to treat lumbar stenosis will be performed in the U.S.4 Decompression involves cutting away overgrown bone and tissue to relieve pressure around the impacted nerve. It is well documented as a successful spine surgery.5,6,7 The majority of lumbar stenosis patients have good results with decompression, and most leave the hospital in a few days and return to normal activities in only a few weeks.7
The iO-Flex® System:
Precision Decompression from the Inside Out®
The iO-Flex® System is the first minimally invasive set of flexible instruments designed to target lumbar stenosis in all three areas, with minimal disruption to the patient’s healthy anatomy. Instead of cutting through healthy pieces of the spine, the iO-Flex® System uses a fine surgical wire to guide the thin iO-Flex® shaver instrument to the location of the overgrown bone and tissue to shave away the stenosis from the inside out (iO).
The iO-Flex® Advantage
- Minimally Invasive Surgery
- Target All Three Areas of Stenosis
- Preserving Healthy Bone and Tissue
Talk With Your Doctor About The iO-Flex® System
There are risks associated with any type of surgery. Your doctor will help explain the risks associated with lumbar decompression surgery using the iO-Flex® System.
