This prospective longitudinal study compares outcomes between Medicare beneficiaries receiving percutaneous image-guided lumbar decompression (PILD), by using the mild® Procedure and a control group of patients receiving interspinous spacers for the treatment of lumbar spinal stenosis (LSS) with neurogenic claudication (NC).

Patients diagnosed with LSS with NC and treated with either the mild® Procedure or a spacer were identified in the Medicare claims database. The study included 2,229 patients in the mild® group and 3,401 patients who were implanted with interspinous spacers.

This comprehensive study of real-world Medicare claims data demonstrated a significantly lower rate of harms for the mild® Procedure compared to interspinous spacers for patients diagnosed with LSS with NC, and a similar rate of subsequent interventions during 2-year follow-up. The rate of harms for those treated with the mild® Procedure was less than half that of patients implanted with a spacer during 2-year follow-up.

These outcomes together with the lower healthcare cost burden for patients receiving mild® is an important element of decision making for treatment of patients early in the LSS continuum of care.
