If you experience pain in your legs, buttock or groin when you stand or walk, you may suffer from a condition called lumbar spinal stenosis.


Lumbar (lower back) spinal stenosis can seriously affect your ability to enjoy the activities of everyday living. Many patients find relief with nonsurgical treatment options. However, if these treatments are not successful, your doctor may recommend surgery.
The Superion™ Interspinous Spacer (ISS) is a potential alternative to traditional spinal surgery designed to relieve chronic pain caused by moderate lumbar spinal stenosis. The Superion™ ISS has been implanted in more than 800 patients worldwide.
A clinical study is now underway to evaluate the safety and effectiveness of the Superion™ ISS for the treatment of moderate lumbar spinal stenosis. The FDA will evaluate data collected from this study to determine whether this device should be made commercially available in the U.S.
You or someone you know may be eligible to participate in this study.
