Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are Medicare beneficiaries diagnosed with lumbar spinal stenosis who are receiving either the MILD procedure or interspinous process decompression.
✕Probably not a fit
Patients who have undergone prior lumbar surgeries such as laminectomy, laminotomy, fusion, or MILD within the last 12 months will not benefit from this study.

What this trial studies
This observational study aims to compare the incidence rates of surgical and minimally invasive interventions among Medicare beneficiaries who have undergone the MILD procedure for lumbar spinal stenosis. It will track outcomes and potential harms associated with the MILD procedure over a 24-month period, using Medicare claims data. The study will include a treatment group of patients receiving MILD and a control group of patients undergoing interspinous process decompression, allowing for a comprehensive analysis of both approaches. Enrollment will continue until the sponsor decides to stop the study.
Why it matters
Potential benefit: If successful, this study could provide valuable insights into the effectiveness and safety of the MILD procedure compared to traditional surgical options for patients with lumbar spinal stenosis.
How similar studies have gone: Other studies have explored similar minimally invasive techniques, but this specific comparison of MILD against interspinous process decompression in a Medicare population is relatively novel.
