Brief Summary:
This prospective longitudinal study will compare incidence rates of Medicare beneficiary surgical and minimally invasive intervention post index procedure, as well as harms associated with the MILD procedure, at 24 months post-treatment with MILD, tested against a control group of similar patients that have had a comparable procedure. This study will start with patients treated with a study procedure having an index date on or after January 1, 2017, and enrollment will continue until stopped by the sponsor.

Condition or disease Intervention/treatment
Lumbar Spinal Stenosis Device: MILD

Detailed Description:
Using the Centers for Medicare and Medicaid (CMS) Medicare Research Identifiable Files (RIFs) containing all medical claims for 100% of Medicare beneficiaries enrolled in the Medicare fee-for-service program, claims-based patient history and demographics will be combined with longitudinal analyses. In this study, the control group will include all patients receiving interspinous process decompression (IPD) for the treatment of lumbar spinal stenosis (LSS) with neurogenic claudication (NC). The treatment group will include all patients receiving MILD during the enrollment period. The date of the MILD and IPD procedure will serve as the index procedure date for 24-month follow-up. This study is exempt from IRB oversight (Department of Health and Human Services regulations 45 CFR 46).

Group/Cohort Intervention/treatment
All Medicare patients treated with MILD as reported via CPT® Code 0275T (or successor code(s)).
Device: MILD
MILD is performed under fluoroscopic image guidance through an ipsilateral interlaminar dorsal approach to the spine. Following epidurography, partial decompression is performed through the removal of tissue and bone at the symptomatic level confirmed with correlated MRI and clinical findings.

Interspinous Process Decompression
All Medicare patients treated with interspinous process decompression (CPT Code 22869 or 22870, or successor code(s)) for the treatment of LSS with NC.

Primary Outcome Measures :
  1. Rate of surgical, minimally invasive intervention. [ Time Frame: 24 months ]
    Measure the rate of Medicare beneficiary surgical and minimally invasive intervention for LSS with NC post index procedure.

  2. Rate of participants with harms associated with the index procedure [ Time Frame: 24 months ]
    Rate of participants with harms associated with the index procedure including, but not limited to, revisions, displacement, mechanical complications, and death. Complications will be counted if they are recorded during the index hospitalization, or any rehospitalization within 30 days of discharge.
