Trial Summary

What is the purpose of this trial?

This trial aims to gather real-world results of using the Superion™ IDS device in everyday medical practice. The device is used to help patients with back problems by relieving pressure on their spinal nerves. It works by creating more space in the spine, which can reduce pain and discomfort.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the Superion™ IDS Device safe for humans?

The Superion™ IDS Device, used for treating lumbar spinal stenosis, is considered safe as it is a minimally invasive procedure that avoids direct surgical removal of tissue near nerves. It is FDA approved and has been shown to be effective and safe in clinical trials, offering a less invasive option compared to traditional surgery. ^{1 2 3 4 5}

How is the Superion™ IDS device treatment different from other treatments for spinal stenosis?

The Superion™ IDS device is a minimally invasive treatment for lumbar spinal stenosis that involves placing a small implant between the bones in the spine to relieve pressure on nerves, unlike traditional surgery that requires more extensive tissue removal. It is unique because it fills the gap between ineffective conservative treatments and more invasive surgeries, offering a less invasive option with significant symptom relief. ^{1 3 4 5 6}

Eligibility Criteria

This trial is for individuals over 45 with lumbar spinal stenosis, experiencing leg/buttock/groin pain that improves when bending forward. Participants must understand the study and commit to follow-ups. Exclusions include those with fixed motor deficits, conditions that could affect outcome reporting, involvement in conflicting trials, or only axial back pain.

Inclusion Criteria

I have signed an informed consent form in English.

I am 45 years old or older.

I have ongoing leg, buttock, or groin pain that gets better when I sit or bend.

Exclusion Criteria

I have a permanent weakness in my leg(s) due to spinal stenosis.

You have a medical or psychological condition, or external factors, that could make it difficult for the study to accurately measure the effects of the treatment on pain (such as a history of certain types of pain, involvement in legal cases, or work-related injuries).

Findings from Research

The Superion Interspinous Spacer is a minimally invasive titanium implant designed to alleviate moderate radicular symptoms in patients with lumbar spinal stenosis by limiting spinal extension and reducing nerve impingement.

Initial clinical results suggest that the Superion device effectively fills the treatment gap between conservative care and invasive surgery, providing a new option for patients who do not respond to traditional treatments.

Rationale, design and clinical performance of the Superion® Interspinous Spacer: a minimally invasive implant for treatment of lumbar spinal stenosis. Loguidice, V., Bini, W., Shabat, S., et al.[2011]

The Superion® interspinous spacer is an FDA-approved minimally invasive device that effectively prevents compression of neural elements in patients with spinal stenosis, showing very large effect sizes in improving disability and symptoms over 2 to 4 years.

This device offers a promising alternative to more invasive surgical options like decompressive laminectomy, potentially reducing the need for such procedures and addressing the growing demand for effective treatments for spinal stenosis.

Interspinous Process Decompression: Expanding Treatment Options for Lumbar Spinal Stenosis. Nunley, PD., Shamie, AN., Blumenthal, SL., et al.[2022]

The Superion interspinous spacer procedure is a minimally invasive option for patients with lumbar spinal stenosis who do not improve with conservative treatments, offering comparable outcomes to traditional laminectomy while potentially reducing costs.

Continuing conservative treatment for over 12 weeks yields only minimal improvements in pain and functionality, making surgical options more effective for patients who do not respond to initial therapies.

Cost-effectiveness and Safety of Interspinous Process Decompression (Superion). Cairns, K., Deer, T., Sayed, D., et al.[2020]

In a 4-year study of 122 patients with moderate lumbar spinal stenosis, 84.3% of those treated with the Superion device showed clinical success in relieving symptoms, indicating its long-term efficacy.

Patients experienced significant improvements in various measures of pain and function, with very large effect sizes, demonstrating that the Superion device effectively alleviates symptoms of intermittent neurogenic claudication.

Superion Interspinous Spacer Treatment of Moderate Spinal Stenosis: 4-Year Results. Nunley, PD., Patel, VV., Orndorff, DG., et al.[2022]

In a 3-year study involving 391 patients with moderate degenerative lumbar spinal stenosis, the Superion(®) device showed a higher success rate (52.5%) compared to the X-STOP(®) control (38.0%) in achieving the primary composite endpoint, indicating its effectiveness in treating this condition.

Patients treated with Superion(®) maintained significant improvements in back and leg pain severity, as well as functional outcomes, demonstrating the long-term efficacy of this treatment.
